Some quick thoughts on the public discussion regarding facial recognition and Amazon Rekognition this past week

Post Syndicated from Dr. Matt Wood original https://aws.amazon.com/blogs/aws/some-quick-thoughts-on-the-public-discussion-regarding-facial-recognition-and-amazon-rekognition-this-past-week/

We have seen a lot of discussion this past week about the role of Amazon Rekognition in facial recognition, surveillance, and civil liberties, and we wanted to share some thoughts.

Amazon Rekognition is a service we announced in 2016. It makes use of new technologies – such as deep learning – and puts them in the hands of developers in an easy-to-use, low-cost way. Since then, we have seen customers use the image and video analysis capabilities of Amazon Rekognition in ways that materially benefit both society (e.g. preventing human trafficking, inhibiting child exploitation, reuniting missing children with their families, and building educational apps for children), and organizations (enhancing security through multi-factor authentication, finding images more easily, or preventing package theft). Amazon Web Services (AWS) is not the only provider of services like these, and we remain excited about how image and video analysis can be a driver for good in the world, including in the public sector and law enforcement.

There have always been and will always be risks with new technology capabilities. Each organization choosing to employ technology must act responsibly or risk legal penalties and public condemnation. AWS takes its responsibilities seriously. But we believe it is the wrong approach to impose a ban on promising new technologies because they might be used by bad actors for nefarious purposes in the future. The world would be a very different place if we had restricted people from buying computers because it was possible to use that computer to do harm. The same can be said of thousands of technologies upon which we all rely each day. Through responsible use, the benefits have far outweighed the risks.

Customers are off to a great start with Amazon Rekognition; the evidence of the positive impact this new technology can provide is strong (and growing by the week), and we’re excited to continue to support our customers in its responsible use.

Majority of Canadians Consume Online Content Legally, Survey Finds

Post Syndicated from Andy original https://torrentfreak.com/majority-of-canadians-consume-online-content-legally-survey-finds-180531/

Back in January, a coalition of companies and organizations with ties to the entertainment industries called on local telecoms regulator CRTC to implement a national website blocking regime.

Under the banner of Fairplay Canada, members including Bell, Cineplex, Directors Guild of Canada, Maple Leaf Sports and Entertainment, Movie Theatre Association of Canada, and Rogers Media, spoke of an industry under threat from marauding pirates. But just how serious is this threat?

The results of a new survey commissioned by Innovation Science and Economic Development Canada (ISED) in collaboration with the Department of Canadian Heritage (PCH) aims to shine light on the problem by revealing the online content consumption habits of citizens in the Great White North.

While there are interesting findings for those on both sides of the site-blocking debate, the situation seems somewhat removed from the Armageddon scenario predicted by the entertainment industries.

Carried out among 3,301 Canadians aged 12 years and over, the Kantar TNS study aims to cover copyright infringement in six key content areas – music, movies, TV shows, video games, computer software, and eBooks. Attitudes and behaviors are also touched upon while measuring the effectiveness of Canada’s copyright measures.

General Digital Content Consumption

In its introduction, the report notes that 28 million Canadians used the Internet in the three-month study period to November 27, 2017. Of those, 22 million (80%) consumed digital content. Around 20 million (73%) streamed or accessed content, 16 million (59%) downloaded content, while 8 million (28%) shared content.

Music, TV shows and movies all battled for first place in the consumption ranks, with 48%, 48%, and 46% respectively.

Copyright Infringement

According to the study, the majority of Canadians do things completely by the book. An impressive 74% of media-consuming respondents said that they’d only accessed material from legal sources in the preceding three months.

The remaining 26% admitted to accessing at least one illegal file in the same period. Of those, just 5% said that all of their consumption was from illegal sources, with movies (36%), software (36%), TV shows (34%) and video games (33%) the most likely content to be consumed illegally.

Interestingly, the study found that few demographic factors – such as gender, region, rural and urban, income, employment status and language – play a role in illegal content consumption.

“We found that only age and income varied significantly between consumers who infringed by downloading or streaming/accessing content online illegally and consumers who did not consume infringing content online,” the report reads.

“More specifically, the profile of consumers who downloaded or streamed/accessed infringing content skewed slightly younger and towards individuals with household incomes of $100K+.”

Licensed services much more popular than pirate haunts

It will come as no surprise that Netflix was the most popular service with consumers, with 64% having used it in the past three months. Sites like YouTube and Facebook were a big hit too, visited by 36% and 28% of content consumers respectively.

Overall, 74% of online content consumers use licensed services for content while 42% use social networks. Under a third (31%) use a combination of peer-to-peer (BitTorrent), cyberlocker platforms, or linking sites. Stream-ripping services are used by 9% of content consumers.

“Consumers who reported downloading or streaming/accessing infringing content only are less likely to use licensed services and more likely to use peer-to-peer/cyberlocker/linking sites than other consumers of online content,” the report notes.

Attitudes towards legal consumption & infringing content

In common with similar surveys over the years, the Kantar research looked at the reasons why people consume content from various sources, both legal and otherwise.

Convenience (48%), speed (36%) and quality (34%) were the most-cited reasons for using legal sources. An interesting 33% of respondents said they use legal sites to avoid using illegal sources.

On the illicit front, 54% of those who obtained unauthorized content in the previous three months said they did so due to it being free, with 40% citing convenience and 34% mentioning speed.

Almost six out of ten (58%) said lower costs would encourage them to switch to official sources, with 47% saying they’d move if legal availability was improved.

Canada’s ‘Notice-and-Notice’ warning system

People in Canada who share content on peer-to-peer systems like BitTorrent without permission run the risk of receiving an infringement notice warning them to stop. These are sent by copyright holders via users’ ISPs and the hope is that the shock of receiving a warning will turn consumers back to the straight and narrow.

The study reveals that 10% of online content consumers over the age of 12 have received one of these notices but what kind of effect have they had?

“Respondents reported that receiving such a notice resulted in the following: increased awareness of copyright infringement (38%), taking steps to ensure password protected home networks (27%), a household discussion about copyright infringement (27%), and discontinuing illegal downloading or streaming (24%),” the report notes.

While these are all positives for the entertainment industries, Kantar reports that almost a quarter (24%) of people who receive a notice simply ignore them.

Stream-ripping

Once upon a time, people obtaining music via P2P networks was cited as the music industry’s greatest threat but, with the advent of sites like YouTube, so-called stream-ripping is the latest bogeyman.

According to the study, 11% of Internet users say they’ve used a stream-ripping service. They are most likely to be male (62%) and predominantly 18 to 34 (52%) years of age.

“Among Canadians who have used a service to stream-rip music or entertainment, nearly half (48%) have used stream-ripping sites, one-third have used downloader apps (38%), one-in-seven (14%) have used a stream-ripping plug-in, and one-in-ten (10%) have used stream-ripping software,” the report adds.

Set-Top Boxes and VPNs

Few general piracy studies would be complete in 2018 without touching on set-top devices and Virtual Private Networks and this report doesn’t disappoint.

More than one in five (21%) respondents aged 12+ reported using a VPN, with the main purpose of securing communications and Internet browsing (57%).

A relatively modest 36% said they use a VPN to access free content while 32% said the aim was to access geo-blocked content unavailable in Canada. Just over a quarter (27%) said that accessing content from overseas at a reasonable price was the main motivator.

One in ten (10%) of respondents reported using a set-top box, with 78% stating they use them to access paid-for content. Interestingly, only a small number say they use the devices to infringe.

“A minority use set-top boxes to access other content that is not legal or they are unsure if it is legal (16%), or to access live sports that are not legal or they are unsure if it is legal (11%),” the report notes.

“Individuals who consumed a mix of legal and illegal content online are more likely to use VPN services (42%) or TV set-top boxes (21%) than consumers who only downloaded or streamed/accessed legal content.”

Kantar says that the findings of the report will be used to help policymakers evaluate how Canada’s Copyright Act is coping with a changing market and technological developments.

“This research will provide the necessary information required to further develop copyright policy in Canada, as well as to provide a foundation to assess the effectiveness of the measures to address copyright infringement, should future analysis be undertaken,” it concludes.

Google’s Chrome Web Store Spammed With Dodgy ‘Pirate’ Movie Links

Post Syndicated from Andy original https://torrentfreak.com/googles-chrome-web-store-spammed-with-dodgy-pirate-movie-links-180527/

Launched in 2010, Google’s Chrome Store is the go-to place for people looking to pimp their Chrome browser.

Often referred to as apps and extensions, the programs offered by the platform run in Chrome and can perform a dazzling array of functions, from improving security and privacy, to streaming video or adding magnet links to torrent sites.

Also available on the Chrome Store are themes, which can be installed locally to change the appearance of the Chrome browser.

While there are certainly plenty to choose from, some additions to the store over the past couple of months are not what most people have come to expect from the add-on platform.

Free movies on Chrome’s Web Store?

As the image above suggests, unknown third parties appear to be exploiting the Chrome Store’s ‘theme’ section to offer visitors access to a wide range of pirate movies including Black Panther, Avengers: Infinity War and Rampage.

When clicking through to the page offering Ready Player One, for example, users are presented with a theme that apparently allows them to watch the movie online in “Full HD Online 4k.”

Of course, the whole scheme is a dubious scam which eventually leads users to Vioos.co, a platform that tries very hard to give the impression of being a pirate streaming portal but actually provides nothing of use.

Nothing to see here

In fact, as soon as one clicks the play button on movies appearing on Vioos.co, visitors are re-directed to another site called Zumastar which asks people to “create a free account” to “access unlimited downloads & streaming.”

“With over 20 million titles, Zumastar is your number one entertainment resource. Join hundreds of thousands of satisfied members and enjoy the hottest movies,” the site promises.

With this kind of marketing, perhaps we should think about this offer for a second. Done. No thanks.

In extended testing, some visits to Vioos.co resulted in a redirection to EtnaMedia.net, a domain that was immediately blocked by MalwareBytes due to suspected fraud. However, after allowing the browser to make the connection, TF was presented with another apparent subscription site.

We didn’t follow through with a sign-up but further searches revealed upset former customers complaining of money being taken from their credit cards when they didn’t expect that to happen.

Quite how many people have signed up to Zumastar or EtnaMedia via this convoluted route from Google’s Chrome Store isn’t clear but a worrying number appear to have installed the ‘themes’ (if that’s what they are) offered on each ‘pirate movie’ page.

At the time of writing the ‘free Watch Rampage Online Full Movie’ ‘theme’ has 2,196 users, the “Watch Avengers Infinity War Full Movie” variant has 974, the ‘Watch Ready Player One 2018 Full HD’ page has 1,031, and the ‘Watch Black Panther Online Free 123putlocker’ ‘theme’ has more than 1,800. Clearly, a worrying number of people will click and install just about anything.

We haven’t tested the supposed themes to see what they do but it’s a cast-iron guarantee that they don’t offer the movies displayed and there’s always a chance they’ll do something awful. As a rule of thumb, it’s nearly always wise to steer clear of anything with “full movie” in the title, they can rarely be trusted.

Finally, those hoping to get some guidance on quality from the reviews on the Chrome Store will be bitterly disappointed.

Garbage reviews, probably left by the scammers

[$] Easier container security with entitlements

Post Syndicated from corbet original https://lwn.net/Articles/755238/rss

During KubeCon
+ CloudNativeCon Europe 2018
, Justin Cormack and Nassim Eddequiouaq presented
a proposal to simplify the setting of security parameters for containerized
applications.
Containers depend on a large set of intricate security primitives that can
have weird interactions. Because they are so hard to use, people often just
turn the whole thing off. The goal of the proposal is to make those
controls easier to understand and use; it is partly inspired by mobile apps
on iOS and Android platforms, an idea that trickled back into Microsoft and
Apple desktops. The time seems ripe to improve the field of
container security, which is in desperate need of simpler controls.

Amazon Sumerian – Now Generally Available

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/amazon-sumerian-now-generally-available/

We announced Amazon Sumerian at AWS re:Invent 2017. As you can see from Tara‘s blog post (Presenting Amazon Sumerian: An Easy Way to Create VR, AR, and 3D Experiences), Sumerian does not require any specialized programming or 3D graphics expertise. You can build VR, AR, and 3D experiences for a wide variety of popular hardware platforms including mobile devices, head-mounted displays, digital signs, and web browsers.

I’m happy to announce that Sumerian is now generally available. You can create realistic virtual environments and scenes without having to acquire or master specialized tools for 3D modeling, animation, lighting, audio editing, or programming. Once built, you can deploy your finished creation across multiple platforms without having to write custom code or deal with specialized deployment systems and processes.

Sumerian gives you a web-based editor that you can use to quickly and easily create realistic, professional-quality scenes. There’s a visual scripting tool that lets you build logic to control how objects and characters (Sumerian Hosts) respond to user actions. Sumerian also lets you create rich, natural interactions powered by AWS services such as Amazon Lex, Polly, AWS Lambda, AWS IoT, and Amazon DynamoDB.

Sumerian was designed to work on multiple platforms. The VR and AR apps that you create in Sumerian will run in browsers that supports WebGL or WebVR and on popular devices such as the Oculus Rift, HTC Vive, and those powered by iOS or Android.

During the preview period, we have been working with a broad spectrum of customers to put Sumerian to the test and to create proof of concept (PoC) projects designed to highlight an equally broad spectrum of use cases, including employee education, training simulations, field service productivity, virtual concierge, design and creative, and brand engagement. Fidelity Labs (the internal R&D unit of Fidelity Investments), was the first to use a Sumerian host to create an engaging VR experience. Cora (the host) lives within a virtual chart room. She can display stock quotes, pull up company charts, and answer questions about a company’s performance. This PoC uses Amazon Polly to implement text to speech and Amazon Lex for conversational chatbot functionality. Read their blog post and watch the video inside to see Cora in action:

Now that Sumerian is generally available, you have the power to create engaging AR, VR, and 3D experiences of your own. To learn more, visit the Amazon Sumerian home page and then spend some quality time with our extensive collection of Sumerian Tutorials.

Securing Your Cryptocurrency

Post Syndicated from Roderick Bauer original https://www.backblaze.com/blog/backing-up-your-cryptocurrency/

Securing Your Cryptocurrency

In our blog post on Tuesday, Cryptocurrency Security Challenges, we wrote about the two primary challenges faced by anyone interested in safely and profitably participating in the cryptocurrency economy: 1) make sure you’re dealing with reputable and ethical companies and services, and, 2) keep your cryptocurrency holdings safe and secure.

In this post, we’re going to focus on how to make sure you don’t lose any of your cryptocurrency holdings through accident, theft, or carelessness. You do that by backing up the keys needed to sell or trade your currencies.

$34 Billion in Lost Value

Of the 16.4 million bitcoins said to be in circulation in the middle of 2017, close to 3.8 million may have been lost because their owners no longer are able to claim their holdings. Based on today’s valuation, that could total as much as $34 billion dollars in lost value. And that’s just bitcoins. There are now over 1,500 different cryptocurrencies, and we don’t know how many of those have been misplaced or lost.



Now that some cryptocurrencies have reached (at least for now) staggering heights in value, it’s likely that owners will be more careful in keeping track of the keys needed to use their cryptocurrencies. For the ones already lost, however, the owners have been separated from their currencies just as surely as if they had thrown Benjamin Franklins and Grover Clevelands over the railing of a ship.

The Basics of Securing Your Cryptocurrencies

In our previous post, we reviewed how cryptocurrency keys work, and the common ways owners can keep track of them. A cryptocurrency owner needs two keys to use their currencies: a public key that can be shared with others is used to receive currency, and a private key that must be kept secure is used to spend or trade currency.

Many wallets and applications allow the user to require extra security to access them, such as a password, or iris, face, or thumb print scan. If one of these options is available in your wallets, take advantage of it. Beyond that, it’s essential to back up your wallet, either using the backup feature built into some applications and wallets, or manually backing up the data used by the wallet. When backing up, it’s a good idea to back up the entire wallet, as some wallets require additional private data to operate that might not be apparent.

No matter which backup method you use, it is important to back up often and have multiple backups, preferable in different locations. As with any valuable data, a 3-2-1 backup strategy is good to follow, which ensures that you’ll have a good backup copy if anything goes wrong with one or more copies of your data.

One more caveat, don’t reuse passwords. This applies to all of your accounts, but is especially important for something as critical as your finances. Don’t ever use the same password for more than one account. If security is breached on one of your accounts, someone could connect your name or ID with other accounts, and will attempt to use the password there, as well. Consider using a password manager such as LastPass or 1Password, which make creating and using complex and unique passwords easy no matter where you’re trying to sign in.

Approaches to Backing Up Your Cryptocurrency Keys

There are numerous ways to be sure your keys are backed up. Let’s take them one by one.

1. Automatic backups using a backup program

If you’re using a wallet program on your computer, for example, Bitcoin Core, it will store your keys, along with other information, in a file. For Bitcoin Core, that file is wallet.dat. Other currencies will use the same or a different file name and some give you the option to select a name for the wallet file.

To back up the wallet.dat or other wallet file, you might need to tell your backup program to explicitly back up that file. Users of Backblaze Backup don’t have to worry about configuring this, since by default, Backblaze Backup will back up all data files. You should determine where your particular cryptocurrency, wallet, or application stores your keys, and make sure the necessary file(s) are backed up if your backup program requires you to select which files are included in the backup.

Backblaze B2 is an option for those interested in low-cost and high security cloud storage of their cryptocurrency keys. Backblaze B2 supports 2-factor verification for account access, works with a number of apps that support automatic backups with encryption, error-recovery, and versioning, and offers an API and command-line interface (CLI), as well. The first 10GB of storage is free, which could be all one needs to store encrypted cryptocurrency keys.

2. Backing up by exporting keys to a file

Apps and wallets will let you export your keys from your app or wallet to a file. Once exported, your keys can be stored on a local drive, USB thumb drive, DAS, NAS, or in the cloud with any cloud storage or sync service you wish. Encrypting the file is strongly encouraged — more on that later. If you use 1Password or LastPass, or other secure notes program, you also could store your keys there.

3. Backing up by saving a mnemonic recovery seed

A mnemonic phrase, mnemonic recovery phrase, or mnemonic seed is a list of words that stores all the information needed to recover a cryptocurrency wallet. Many wallets will have the option to generate a mnemonic backup phrase, which can be written down on paper. If the user’s computer no longer works or their hard drive becomes corrupted, they can download the same wallet software again and use the mnemonic recovery phrase to restore their keys.

The phrase can be used by anyone to recover the keys, so it must be kept safe. Mnemonic phrases are an excellent way of backing up and storing cryptocurrency and so they are used by almost all wallets.

A mnemonic recovery seed is represented by a group of easy to remember words. For example:

eye female unfair moon genius pipe nuclear width dizzy forum cricket know expire purse laptop scale identify cube pause crucial day cigar noise receive

The above words represent the following seed:

0a5b25e1dab6039d22cd57469744499863962daba9d2844243fec 9c0313c1448d1a0b2cd9e230a78775556f9b514a8be45802c2808e fd449a20234e9262dfa69

These words have certain properties:

  • The first four letters are enough to unambiguously identify the word.
  • Similar words are avoided (such as: build and built).

Bitcoin and most other cryptocurrencies such as Litecoin, Ethereum, and others use mnemonic seeds that are 12 to 24 words long. Other currencies might use different length seeds.

4. Physical backups — Paper, Metal

Some cryptocurrency holders believe that their backup, or even all their cryptocurrency account information, should be stored entirely separately from the internet to avoid any risk of their information being compromised through hacks, exploits, or leaks. This type of storage is called “cold storage.” One method of cold storage involves printing out the keys to a piece of paper and then erasing any record of the keys from all computer systems. The keys can be entered into a program from the paper when needed, or scanned from a QR code printed on the paper.

Printed public and private keys

Printed public and private keys

Some who go to extremes suggest separating the mnemonic needed to access an account into individual pieces of paper and storing those pieces in different locations in the home or office, or even different geographical locations. Some say this is a bad idea since it could be possible to reconstruct the mnemonic from one or more pieces. How diligent you wish to be in protecting these codes is up to you.

There’s another option that could make you the envy of your friends. That’s the CryptoSteel wallet, which is a stainless steel metal case that comes with more than 250 stainless steel letter tiles engraved on each side. Codes and passwords are assembled manually from the supplied part-randomized set of tiles. Users are able to store up to 96 characters worth of confidential information. Cryptosteel claims to be fireproof, waterproof, and shock-proof.

Of course, if you leave your Cryptosteel wallet in the pocket of a pair of ripped jeans that gets thrown out by the housekeeper, as happened to the character Russ Hanneman on the TV show Silicon Valley in last Sunday’s episode, then you’re out of luck. That fictional billionaire investor lost a USB drive with $300 million in cryptocoins. Let’s hope that doesn’t happen to you.

Encryption & Security

Whether you store your keys on your computer, an external disk, a USB drive, DAS, NAS, or in the cloud, you want to make sure that no one else can use those keys. The best way to handle that is to encrypt the backup.

With Backblaze Backup for Windows and Macintosh, your backups are encrypted in transmission to the cloud and on the backup server. Users have the option to add an additional level of security by adding a Personal Encryption Key (PEK), which secures their private key. Your cryptocurrency backup files are secure in the cloud. Using our web or mobile interface, previous versions of files can be accessed, as well.

Our object storage cloud offering, Backblaze B2, can be used with a variety of applications for Windows, Macintosh, and Linux. With B2, cryptocurrency users can choose whichever method of encryption they wish to use on their local computers and then upload their encrypted currency keys to the cloud. Depending on the client used, versioning and life-cycle rules can be applied to the stored files.

Other backup programs and systems provide some or all of these capabilities, as well. If you are backing up to a local drive, it is a good idea to encrypt the local backup, which is an option in some backup programs.

Address Security

Some experts recommend using a different address for each cryptocurrency transaction. Since the address is not the same as your wallet, this means that you are not creating a new wallet, but simply using a new identifier for people sending you cryptocurrency. Creating a new address is usually as easy as clicking a button in the wallet.

One of the chief advantages of using a different address for each transaction is anonymity. Each time you use an address, you put more information into the public ledger (blockchain) about where the currency came from or where it went. That means that over time, using the same address repeatedly could mean that someone could map your relationships, transactions, and incoming funds. The more you use that address, the more information someone can learn about you. For more on this topic, refer to Address reuse.

Note that a downside of using a paper wallet with a single key pair (type-0 non-deterministic wallet) is that it has the vulnerabilities listed above. Each transaction using that paper wallet will add to the public record of transactions associated with that address. Newer wallets, i.e. “deterministic” or those using mnemonic code words support multiple addresses and are now recommended.

There are other approaches to keeping your cryptocurrency transaction secure. Here are a couple of them.

Multi-signature

Multi-signature refers to requiring more than one key to authorize a transaction, much like requiring more than one key to open a safe. It is generally used to divide up responsibility for possession of cryptocurrency. Standard transactions could be called “single-signature transactions” because transfers require only one signature — from the owner of the private key associated with the currency address (public key). Some wallets and apps can be configured to require more than one signature, which means that a group of people, businesses, or other entities all must agree to trade in the cryptocurrencies.

Deep Cold Storage

Deep cold storage ensures the entire transaction process happens in an offline environment. There are typically three elements to deep cold storage.

First, the wallet and private key are generated offline, and the signing of transactions happens on a system not connected to the internet in any manner. This ensures it’s never exposed to a potentially compromised system or connection.

Second, details are secured with encryption to ensure that even if the wallet file ends up in the wrong hands, the information is protected.

Third, storage of the encrypted wallet file or paper wallet is generally at a location or facility that has restricted access, such as a safety deposit box at a bank.

Deep cold storage is used to safeguard a large individual cryptocurrency portfolio held for the long term, or for trustees holding cryptocurrency on behalf of others, and is possibly the safest method to ensure a crypto investment remains secure.

Keep Your Software Up to Date

You should always make sure that you are using the latest version of your app or wallet software, which includes important stability and security fixes. Installing updates for all other software on your computer or mobile device is also important to keep your wallet environment safer.

One Last Thing: Think About Your Testament

Your cryptocurrency funds can be lost forever if you don’t have a backup plan for your peers and family. If the location of your wallets or your passwords is not known by anyone when you are gone, there is no hope that your funds will ever be recovered. Taking a bit of time on these matters can make a huge difference.

If your day has been a little fraught so far, watch this video. It opens with a tableau of methodically laid-out components and then shows them soldered, screwed, and slotted neatly into place. Everything fits perfectly; nothing needs percussive adjustment. Then it shows us glimpses of an AR future just like the one promised in the less dystopian comics and TV programmes of my 1980s childhood. It is all very soothing, and exactly what I needed.

Creating augmented reality with projection

We’ve seen plenty of Raspberry Pi IoT builds that are smart devices for the home; they add computing power to things like lights, door locks, or toasters to make these objects interact with humans and with their environment in new ways. Nord ProjectsLantern takes a different approach. In their words, it:

imagines a future where projections are used to present ambient information, and relevant UI within everyday objects. Point it at a clock to show your appointments, or point to speaker to display the currently playing song. Unlike a screen, when Lantern’s projections are no longer needed, they simply fade away.

Lantern is set up so that you can connect your wireless device to it using Google Nearby. This means there’s no need to create an account before you can dive into augmented reality.

Your own open-source AR lamp

Nord Projects collaborated on Lantern with Google’s Android Things team. They’ve made it fully open-source, so you can find the code on GitHub and also download their parts list, which includes a Pi, an IKEA lamp, an accelerometer, and a laser projector. Build instructions are at hackster.io and on GitHub.

This is a particularly clear tutorial, very well illustrated with photos and GIFs, and once you’ve sourced and 3D-printed all of the components, you shouldn’t need a whole lot of experience to put everything together successfully. Since everything is open-source, though, if you want to adapt it — for example, if you’d like to source a less costly projector than the snazzy one used here — you can do that too.

The instructions walk you through the mechanical build and the wiring, as well as installing Android Things and Nord Projects’ custom software on the Raspberry Pi. Once you’ve set everything up, an accelerometer connected to the Pi’s GPIO pins lets the lamp know which surface it is pointing at. A companion app on your mobile device lets you choose from the mini apps that work on that surface to select the projection you want.

The designers are making several mini apps available for Lantern, including the charmingly named Space Porthole: this uses Processing and your local longitude and latitude to project onto your ceiling the stars you’d see if you punched a hole through to the sky, if it were night time, and clear weather. Wouldn’t you rather look at that than deal with the ant problem in your kitchen or tackle your GitHub notifications?

Supply-Chain Security

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/05/supply-chain_se.html

Earlier this month, the Pentagon stopped selling phones made by the Chinese companies ZTE and Huawei on military bases because they might be used to spy on their users.

It’s a legitimate fear, and perhaps a prudent action. But it’s just one instance of the much larger issue of securing our supply chains.

All of our computerized systems are deeply international, and we have no choice but to trust the companies and governments that touch those systems. And while we can ban a few specific products, services or companies, no country can isolate itself from potential foreign interference.

In this specific case, the Pentagon is concerned that the Chinese government demanded that ZTE and Huawei add “backdoors” to their phones that could be surreptitiously turned on by government spies or cause them to fail during some future political conflict. This tampering is possible because the software in these phones is incredibly complex. It’s relatively easy for programmers to hide these capabilities, and correspondingly difficult to detect them.

This isn’t the first time the United States has taken action against foreign software suspected to contain hidden features that can be used against us. Last December, President Trump signed into law a bill banning software from the Russian company Kaspersky from being used within the US government. In 2012, the focus was on Chinese-made Internet routers. Then, the House Intelligence Committee concluded: “Based on available classified and unclassified information, Huawei and ZTE cannot be trusted to be free of foreign state influence and thus pose a security threat to the United States and to our systems.”

Nor is the United States the only country worried about these threats. In 2014, China reportedly banned antivirus products from both Kaspersky and the US company Symantec, based on similar fears. In 2017, the Indian government identified 42 smartphone apps that China subverted. Back in 1997, the Israeli company Check Point was dogged by rumors that its government added backdoors into its products; other of that country’s tech companies have been suspected of the same thing. Even al-Qaeda was concerned; ten years ago, a sympathizer released the encryption software Mujahedeen Secrets, claimed to be free of Western influence and backdoors. If a country doesn’t trust another country, then it can’t trust that country’s computer products.

But this trust isn’t limited to the country where the company is based. We have to trust the country where the software is written — and the countries where all the components are manufactured. In 2016, researchers discovered that many different models of cheap Android phones were sending information back to China. The phones might be American-made, but the software was from China. In 2016, researchers demonstrated an even more devious technique, where a backdoor could be added at the computer chip level in the factory that made the chips ­ without the knowledge of, and undetectable by, the engineers who designed the chips in the first place. Pretty much every US technology company manufactures its hardware in countries such as Malaysia, Indonesia, China and Taiwan.

We also have to trust the programmers. Today’s large software programs are written by teams of hundreds of programmers scattered around the globe. Backdoors, put there by we-have-no-idea-who, have been discovered in Juniper firewalls and D-Link routers, both of which are US companies. In 2003, someone almost slipped a very clever backdoor into Linux. Think of how many countries’ citizens are writing software for Apple or Microsoft or Google.

We can go even farther down the rabbit hole. We have to trust the distribution systems for our hardware and software. Documents disclosed by Edward Snowden showed the National Security Agency installing backdoors into Cisco routers being shipped to the Syrian telephone company. There are fake apps in the Google Play store that eavesdrop on you. Russian hackers subverted the update mechanism of a popular brand of Ukrainian accounting software to spread the NotPetya malware.

In 2017, researchers demonstrated that a smartphone can be subverted by installing a malicious replacement screen.

I could go on. Supply-chain security is an incredibly complex problem. US-only design and manufacturing isn’t an option; the tech world is far too internationally interdependent for that. We can’t trust anyone, yet we have no choice but to trust everyone. Our phones, computers, software and cloud systems are touched by citizens of dozens of different countries, any one of whom could subvert them at the demand of their government. And just as Russia is penetrating the US power grid so they have that capability in the event of hostilities, many countries are almost certainly doing the same thing at the consumer level.

We don’t know whether the risk of Huawei and ZTE equipment is great enough to warrant the ban. We don’t know what classified intelligence the United States has, and what it implies. But we do know that this is just a minor fix for a much larger problem. It’s doubtful that this ban will have any real effect. Members of the military, and everyone else, can still buy the phones. They just can’t buy them on US military bases. And while the US might block the occasional merger or acquisition, or ban the occasional hardware or software product, we’re largely ignoring that larger issue. Solving it borders on somewhere between incredibly expensive and realistically impossible.

Perhaps someday, global norms and international treaties will render this sort of device-level tampering off-limits. But until then, all we can do is hope that this particular arms race doesn’t get too far out of control.

Creating a 1.3 Million vCPU Grid on AWS using EC2 Spot Instances and TIBCO GridServer

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/creating-a-1-3-million-vcpu-grid-on-aws-using-ec2-spot-instances-and-tibco-gridserver/

Many of my colleagues are fortunate to be able to spend a good part of their day sitting down with and listening to our customers, doing their best to understand ways that we can better meet their business and technology needs. This information is treated with extreme care and is used to drive the roadmap for new services and new features.

AWS customers in the financial services industry (often abbreviated as FSI) are looking ahead to the Fundamental Review of Trading Book (FRTB) regulations that will come in to effect between 2019 and 2021. Among other things, these regulations mandate a new approach to the “value at risk” calculations that each financial institution must perform in the four hour time window after trading ends in New York and begins in Tokyo. Today, our customers report this mission-critical calculation consumes on the order of 200,000 vCPUs, growing to between 400K and 800K vCPUs in order to meet the FRTB regulations. While there’s still some debate about the magnitude and frequency with which they’ll need to run this expanded calculation, the overall direction is clear.

Building a Big Grid
In order to make sure that we are ready to help our FSI customers meet these new regulations, we worked with TIBCO to set up and run a proof of concept grid in the AWS Cloud. The periodic nature of the calculation, along with the amount of processing power and storage needed to run it to completion within four hours, make it a great fit for an environment where a vast amount of cost-effective compute power is available on an on-demand basis.

Our customers are already using the TIBCO GridServer on-premises and want to use it in the cloud. This product is designed to run grids at enterprise scale. It runs apps in a virtualized fashion, and accepts requests for resources, dynamically provisioning them on an as-needed basis. The cloud version supports Amazon Linux as well as the PostgreSQL-compatible edition of Amazon Aurora.

Working together with TIBCO, we set out to create a grid that was substantially larger than the current high-end prediction of 800K vCPUs, adding a 50% safety factor and then rounding up to reach 1.3 million vCPUs (5x the size of the largest on-premises grid). With that target in mind, the account limits were raised as follows:

  • Spot Instance Limit – 120,000
  • EBS Volume Limit – 120,000
  • EBS Capacity Limit – 2 PB

If you plan to create a grid of this size, you should also bring your friendly local AWS Solutions Architect into the loop as early as possible. They will review your plans, provide you with architecture guidance, and help you to schedule your run.

Running the Grid
We hit the Go button and launched the grid, watching as it bid for and obtained Spot Instances, each of which booted, initialized, and joined the grid within two minutes. The test workload used the Strata open source analytics & market risk library from OpenGamma and was set up with their assistance.

The grid grew to 61,299 Spot Instances (1.3 million vCPUs drawn from 34 instance types spanning 3 generations of EC2 hardware) as planned, with just 1,937 instances reclaimed and automatically replaced during the run, and cost $30,000 per hour to run, at an average hourly cost of $0.078 per vCPU. If the same instances had been used in On-Demand form, the hourly cost to run the grid would have been approximately $93,000.

Despite the scale of the grid, prices for the EC2 instances did not move during the bidding process. This is due to the overall size of the AWS Cloud and the smooth price change model that we launched late last year.

To give you a sense of the compute power, we computed that this grid would have taken the #1 position on the TOP 500 supercomputer list in November 2007 by a considerable margin, and the #2 position in June 2008. Today, it would occupy position #360 on the list.

I hope that you enjoyed this AWS success story, and that it gives you an idea of the scale that you can achieve in the cloud!

Cryptocurrency Security Challenges

Post Syndicated from Roderick Bauer original https://www.backblaze.com/blog/cryptocurrency-security-challenges/

Physical coins representing cyrptocurrencies

Most likely you’ve read the tantalizing stories of big gains from investing in cryptocurrencies. Someone who invested $1,000 into bitcoins five years ago would have over $85,000 in value now. Alternatively, someone who invested in bitcoins three months ago would have seen their investment lose 20% in value. Beyond the big price fluctuations, currency holders are possibly exposed to fraud, bad business practices, and even risk losing their holdings altogether if they are careless in keeping track of the all-important currency keys.

It’s certain that beyond the rewards and risks, cryptocurrencies are here to stay. We can’t ignore how they are changing the game for how money is handled between people and businesses.

Some Advantages of Cryptocurrency

  • Cryptocurrency is accessible to anyone.
  • Decentralization means the network operates on a user-to-user (or peer-to-peer) basis.
  • Transactions can completed for a fraction of the expense and time required to complete traditional asset transfers.
  • Transactions are digital and cannot be counterfeited or reversed arbitrarily by the sender, as with credit card charge-backs.
  • There aren’t usually transaction fees for cryptocurrency exchanges.
  • Cryptocurrency allows the cryptocurrency holder to send exactly what information is needed and no more to the merchant or recipient, even permitting anonymous transactions (for good or bad).
  • Cryptocurrency operates at the universal level and hence makes transactions easier internationally.
  • There is no other electronic cash system in which your account isn’t owned by someone else.

On top of all that, blockchain, the underlying technology behind cryptocurrencies, is already being applied to a variety of business needs and itself becoming a hot sector of the tech economy. Blockchain is bringing traceability and cost-effectiveness to supply-chain management — which also improves quality assurance in areas such as food, reducing errors and improving accounting accuracy, smart contracts that can be automatically validated, signed and enforced through a blockchain construct, the possibility of secure, online voting, and many others.

Like any new, booming marketing there are risks involved in these new currencies. Anyone venturing into this domain needs to have their eyes wide open. While the opportunities for making money are real, there are even more ways to lose money.

We’re going to cover two primary approaches to staying safe and avoiding fraud and loss when dealing with cryptocurrencies. The first is to thoroughly vet any person or company you’re dealing with to judge whether they are ethical and likely to succeed in their business segment. The second is keeping your critical cryptocurrency keys safe, which we’ll deal with in this and a subsequent post.

Caveat Emptor — Buyer Beware

The short history of cryptocurrency has already seen the demise of a number of companies that claimed to manage, mine, trade, or otherwise help their customers profit from cryptocurrency. Mt. Gox, GAW Miners, and OneCoin are just three of the many companies that disappeared with their users’ money. This is the traditional equivalent of your bank going out of business and zeroing out your checking account in the process.

That doesn’t happen with banks because of regulatory oversight. But with cryptocurrency, you need to take the time to investigate any company you use to manage or trade your currencies. How long have they been around? Who are their investors? Are they affiliated with any reputable financial institutions? What is the record of their founders and executive management? These are all important questions to consider when evaluating a company in this new space.

Would you give the keys to your house to a service or person you didn’t thoroughly know and trust? Some companies that enable you to buy and sell currencies online will routinely hold your currency keys, which gives them the ability to do anything they want with your holdings, including selling them and pocketing the proceeds if they wish.

That doesn’t mean you shouldn’t ever allow a company to keep your currency keys in escrow. It simply means that you better know with whom you’re doing business and if they’re trustworthy enough to be given that responsibility.

Keys To the Cryptocurrency Kingdom — Public and Private

If you’re an owner of cryptocurrency, you know how this all works. If you’re not, bear with me for a minute while I bring everyone up to speed.

Cryptocurrency has no physical manifestation, such as bills or coins. It exists purely as a computer record. And unlike currencies maintained by governments, such as the U.S. dollar, there is no central authority regulating its distribution and value. Cryptocurrencies use a technology called blockchain, which is a decentralized way of keeping track of transactions. There are many copies of a given blockchain, so no single central authority is needed to validate its authenticity or accuracy.

The validity of each cryptocurrency is determined by a blockchain. A blockchain is a continuously growing list of records, called “blocks”, which are linked and secured using cryptography. Blockchains by design are inherently resistant to modification of the data. They perform as an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable, permanent way. A blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority. On a scaled network, this level of collusion is impossible — making blockchain networks effectively immutable and trustworthy.

Blockchain process

The other element common to all cryptocurrencies is their use of public and private keys, which are stored in the currency’s wallet. A cryptocurrency wallet stores the public and private “keys” or “addresses” that can be used to receive or spend the cryptocurrency. With the private key, it is possible to write in the public ledger (blockchain), effectively spending the associated cryptocurrency. With the public key, it is possible for others to send currency to the wallet.

What is a cryptocurrency address?

Cryptocurrency “coins” can be lost if the owner loses the private keys needed to spend the currency they own. It’s as if the owner had lost a bank account number and had no way to verify their identity to the bank, or if they lost the U.S. dollars they had in their wallet. The assets are gone and unusable.

The Cryptocurrency Wallet

Given the importance of these keys, and lack of recourse if they are lost, it’s obviously very important to keep track of your keys.

If you’re being careful in choosing reputable exchanges, app developers, and other services with whom to trust your cryptocurrency, you’ve made a good start in keeping your investment secure. But if you’re careless in managing the keys to your bitcoins, ether, Litecoin, or other cryptocurrency, you might as well leave your money on a cafe tabletop and walk away.

What Are the Differences Between Hot and Cold Wallets?

Just like other numbers you might wish to keep track of — credit cards, account numbers, phone numbers, passphrases — cryptocurrency keys can be stored in a variety of ways. Those who use their currencies for day-to-day purchases most likely will want them handy in a smartphone app, hardware key, or debit card that can be used for purchases. These are called “hot” wallets. Some experts advise keeping the balances in these devices and apps to a minimal amount to avoid hacking or data loss. We typically don’t walk around with thousands of dollars in U.S. currency in our old-style wallets, so this is really a continuation of the same approach to managing spending money.

Some investors with large balances keep their keys in “cold” wallets, or “cold storage,” i.e. a device or location that is not connected online. If funds are needed for purchases, they can be transferred to a more easily used payment medium. Cold wallets can be hardware devices, USB drives, or even paper copies of your keys.

Wallets are suited to holding one or more specific cryptocurrencies, and some people have multiple wallets for different currencies and different purposes.

A paper wallet is nothing other than a printed record of your public and private keys. Some prefer their records to be completely disconnected from the internet, and a piece of paper serves that need. Just like writing down an account password on paper, however, it’s essential to keep the paper secure to avoid giving someone the ability to freely access your funds.

How to Keep your Keys, and Cryptocurrency Secure

In a post this coming Thursday, Securing Your Cryptocurrency, we’ll discuss the best strategies for backing up your cryptocurrency so that your currencies don’t become part of the millions that have been lost. We’ll cover the common (and uncommon) approaches to backing up hot wallets, cold wallets, and using paper and metal solutions to keeping your keys safe.

In the meantime, please tell us of your experiences with cryptocurrencies — good and bad — and how you’ve dealt with the issue of cryptocurrency security.

Ray Ozzie’s Encryption Backdoor

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/05/ray_ozzies_encr.html

Last month, Wired published a long article about Ray Ozzie and his supposed new scheme for adding a backdoor in encrypted devices. It’s a weird article. It paints Ozzie’s proposal as something that “attains the impossible” and “satisfies both law enforcement and privacy purists,” when (1) it’s barely a proposal, and (2) it’s essentially the same key escrow scheme we’ve been hearing about for decades.

Basically, each device has a unique public/private key pair and a secure processor. The public key goes into the processor and the device, and is used to encrypt whatever user key encrypts the data. The private key is stored in a secure database, available to law enforcement on demand. The only other trick is that for law enforcement to use that key, they have to put the device in some sort of irreversible recovery mode, which means it can never be used again. That’s basically it.

I have no idea why anyone is talking as if this were anything new. Several cryptographers have already explained why this key escrow scheme is no better than any other key escrow scheme. The short answer is (1) we won’t be able to secure that database of backdoor keys, (2) we don’t know how to build the secure coprocessor the scheme requires, and (3) it solves none of the policy problems around the whole system. This is the typical mistake non-cryptographers make when they approach this problem: they think that the hard part is the cryptography to create the backdoor. That’s actually the easy part. The hard part is ensuring that it’s only used by the good guys, and there’s nothing in Ozzie’s proposal that addresses any of that.

I worry that this kind of thing is damaging in the long run. There should be some rule that any backdoor or key escrow proposal be a fully specified proposal, not just some cryptography and hand-waving notions about how it will be used in practice. And before it is analyzed and debated, it should have to satisfy some sort of basic security analysis. Otherwise, we’ll be swatting pseudo-proposals like this one, while those on the other side of this debate become increasingly convinced that it’s possible to design one of these things securely.

Already people are using the National Academies report on backdoors for law enforcement as evidence that engineers are developing workable and secure backdoors. Writing in Lawfare, Alan Z. Rozenshtein claims that the report — and a related New York Times story — “undermine the argument that secure third-party access systems are so implausible that it’s not even worth trying to develop them.” Susan Landau effectively corrects this misconception, but the damage is done.

Here’s the thing: it’s not hard to design and build a backdoor. What’s hard is building the systems — both technical and procedural — around them. Here’s Rob Graham:

He’s only solving the part we already know how to solve. He’s deliberately ignoring the stuff we don’t know how to solve. We know how to make backdoors, we just don’t know how to secure them.

A bunch of us cryptographers have already explained why we don’t think this sort of thing will work in the foreseeable future. We write:

Exceptional access would force Internet system developers to reverse “forward secrecy” design practices that seek to minimize the impact on user privacy when systems are breached. The complexity of today’s Internet environment, with millions of apps and globally connected services, means that new law enforcement requirements are likely to introduce unanticipated, hard to detect security flaws. Beyond these and other technical vulnerabilities, the prospect of globally deployed exceptional access systems raises difficult problems about how such an environment would be governed and how to ensure that such systems would respect human rights and the rule of law.

Finally, Matthew Green:

The reason so few of us are willing to bet on massive-scale key escrow systems is that we’ve thought about it and we don’t think it will work. We’ve looked at the threat model, the usage model, and the quality of hardware and software that exists today. Our informed opinion is that there’s no detection system for key theft, there’s no renewability system, HSMs are terrifically vulnerable (and the companies largely staffed with ex-intelligence employees), and insiders can be suborned. We’re not going to put the data of a few billion people on the line an environment where we believe with high probability that the system will fail.

EDITED TO ADD (5/14): An analysis of the proposal.

Danish Traffic to Pirate Sites Increases 67% in Just a Year

Post Syndicated from Andy original https://torrentfreak.com/danish-traffic-to-pirate-sites-increases-67-in-just-a-year-180501/

For close to 20 years, rightsholders have tried to stem the tide of mainstream Internet piracy. Yet despite increasingly powerful enforcement tools, infringement continues on a grand scale.

While the problem is global, rightsholder groups often zoom in on their home turf, to see how the fight is progressing locally. Covering Denmark, the Rights Alliance Data Report 2017 paints a fairly pessimistic picture.

Published this week, the industry study – which uses SimilarWeb and MarkMonitor data – finds that Danes visited 2,000 leading pirate sites 596 million times in 2017. That represents a 67% increase over the 356 million visits to unlicensed platforms made by citizens during 2016.

The report notes that, at least in part, this explosive growth can be attributed to mobile-compatible sites and services, which make it easier than ever to consume illicit content on the move, as well as at home.

In a sea of unauthorized streaming sites, Rights Alliance highlights one platform above all the others as a particularly bad influence in 2017 – 123movies (also known as GoMovies and GoStream, among others).

“The popularity of this service rose sharply in 2017 from 40 million visits in 2016 to 175 million visits in 2017 – an increase of 337 percent, of which most of the traffic originates from mobile devices,” the report notes.

123movies recently announced its closure but before that the platform was subjected to web-blocking in several jurisdictions.

Rights Alliance says that Denmark has one of the most effective blocking systems in the world but that still doesn’t stop huge numbers of people from consuming pirate content from sites that aren’t yet blocked.

“Traffic to infringing sites is overwhelming, and therefore blocking a few sites merely takes the top of the illegal activities,” Rights Alliance chief Maria Fredenslund informs TorrentFreak.

“Blocking is effective by stopping 75% of traffic to blocked sites but certainly, an upscaled effort is necessary.”

Rights Alliance also views the promotion of legal services as crucial to its anti-piracy strategy so when people visit a blocked site, they’re also directed towards legitimate platforms.

“That is why we are working at the moment with Denmark’s Ministry of Culture and ISPs on a campaign ‘Share With Care 2′ which promotes legal services e.g. by offering a search function for legal services which will be placed in combination with the signs that are put on blocked websites,” the anti-piracy group notes.

But even with such measures in place, the thirst for unlicensed content is great. In 2017 alone, 500 of the most popular films and TV shows were downloaded from P2P networks like BitTorrent more than 15 million times from Danish IP addresses, that’s up from 11.9 million in 2016.

Given the dramatic rise in visits to pirate sites overall, the suggestion is that plenty of consumers are still getting through. Rights Alliance says that the number of people being restricted is also hampered by people who don’t use their ISP’s DNS service, which is the method used to block sites in Denmark.

Additionally, interest in VPNs and similar anonymization and bypass-capable technologies is on the increase. Between 3.5% and 5% of Danish Internet users currently use a VPN, a number that’s expected to go up. Furthermore, Rights Alliance reports greater interest in “closed” pirate communities.

“The data is based on closed [BitTorrent] networks. We also address the challenges with private communities on Facebook and other [social media] platforms,” Fredenslund explains.

“Due to the closed doors of these platforms it is not possible for us to say anything precisely about the amount of infringing activities there. However, we receive an increasing number of notices from our members who discover that their products are distributed illegally and also we do an increased monitoring of these platforms.”

But while more established technologies such as torrents and regular web-streaming continue in considerable volumes, newer IPTV-style services accessible via apps and dedicated platforms are also gaining traction.

“The volume of visitors to these services’ websites has been sharply rising in 2017 – an increase of 84 percent from January to December,” Rights Alliance notes.

“Even though the number of visitors does not say anything about actual consumption, as users usually only visit pages one time to download the program, the number gives an indication that the interest in IPTV is increasing.”

To combat this growth market, Rights Alliance says it wants to establish web-blockades against sites hosting the software applications.

Also on the up are visits to platforms offering live sports illegally. In 2017, Danish IP addresses made 2.96 million visits to these services, corresponding to almost 250,000 visits per month and representing an annual increase of 28%.

Rights Alliance informs TF that in future a ‘live’ blocking mechanism similar to the one used by the Premier League in the UK could be deployed in Denmark.

“We already have a dynamic blocking system, and we see an increasing demand for illegal TV products, so this could be a natural next step,” Fredenslund explains.

Another small but perhaps significant detail is how users are accessing pirate sites. According to the report, large volumes of people are now visiting platforms directly, with more than 50% doing so in preference to referrals from search engines such as Google.

In terms of deterrence, the Rights Alliance report sticks to the tried-and-tested approaches seen so often in the anti-piracy arena.

Firstly, the group notes that it’s increasingly encountering people who are paying for legal services such as Netflix and Spotify so believe that allows them to grab something extra from a pirate site. However, in common with similar organizations globally, the group counters that pirate sites can serve malware or have other nefarious business interests behind the scenes, so people should stay away.

Whether significant volumes will heed this advice will remain to be seen but if a 67% increase last year is any predictor of the future, piracy is here to stay – and then some. Rights Alliance says it is ready for the challenge but will need some assistance to achieve its goals.

“As it is evident from the traffic data, criminal activities are not something that we, private companies (right holders in cooperation with ISPs), can handle alone,” Fredenslund says.

“Therefore, we are very pleased that DK Government recently announced that the IP taskforce which was set down as a trial period has now been made permanent. In that regard it is important and necessary that the police will also obtain the authority to handle blocking of massively infringing websites. Police do not have the authority to carry out blocking as it is today.”

Stream your video gaming exploits to the internet at the touch of a button with the Twitch-O-Matic. Everyone else is doing it, so you should too.

Twitch-O-Matic: Raspberry Pi Twitch Streaming Device – Weekend Hacker #1804

Some gaming consoles make it easy to stream to Twitch, some gaming consoles don’t (come on, Nintendo). So for those that don’t, I’ve made this beta version of the “Twitch-O-Matic”. No it doesn’t chop onions or fold your laundry, but what it DOES do is stream anything with HDMI output to your Twitch channel with the simple push of a button!

eSports and online game streaming

Interest in eSports has skyrocketed over the last few years, with viewership numbers in the hundreds of millions, sponsorship deals increasing in value and prestige, and tournament prize funds reaching millions of dollars. So it’s no wonder that more and more gamers are starting to stream live to online platforms in order to boost their fanbase and try to cash in on this growing industry.

Streaming to Twitch

Launched in 2011, Twitch.tv is an online live-streaming platform with a primary focus on video gaming. Users can create accounts to contribute their comments and content to the site, as well as watching live-streamed gaming competitions and broadcasts. With a staggering fifteen million daily users, Twitch is accessible via smartphone and gaming console apps, smart TVs, computers, and tablets. But if you want to stream to Twitch, you may find yourself using third-party software in order to do so. And with more buttons to click and more wires to plug in for older, app-less consoles, streaming can get confusing.

Enter Tinkernut.

We’ve featured Tinkernut a few times on the Raspberry Pi blog – his tutorials are clear, his projects are interesting and useful, and his live-streamed comment videos for every build are a nice touch to sharing homebrew builds on the internet.

So, yes, we love him. [This is true. Alex never shuts up about him. – Ed.] And since he has over 500K subscribers on YouTube, we’re obviously not the only ones. We wave our Tinkernut flags with pride.

Twitch-O-Matic

With a Raspberry Pi Zero W, an HDMI to CSI adapter, and a case to fit it all in, Tinkernut’s Twitch-O-Matic allows easy connection to the Twitch streaming service. You’ll also need a button – the bigger, the better in our opinion, though Tinkernut has opted for the Adafruit 16mm Illuminated Pushbutton for his build, and not the 100mm Massive Arcade Button that, sadly, we still haven’t found a reason to use yet.

For added frills and pizzazz, Tinketnut has also incorporated Adafruit’s White LED Backlight Module into the case, though you don’t have to do so unless you’re feeling super fancy.

The setup

The Raspberry Pi Zero W is connected to the HDMI to CSI adapter via the camera connector, in the same way you’d attach the camera ribbon. Tinkernut uses a standard Raspbian image on an 8GB SD card, with SSH enabled for remote access from his laptop. He uses the simple command Raspivid to test the HDMI connection by recording ten seconds of video footage from his console.

One lead is all you need

Once you have the Pi receiving video from your console, you can connect to Twitch using your Twitch stream key, which you can find by logging in to your account at Twitch.tv. Tinkernut’s tutorial gives you all the commands you need to stream from your Pi.

The frills

To up the aesthetic impact of your project, adding buttons and backlights is fairly straightforward.

Pretty LED frills

To run the stream command, Tinketnut uses a button: press once to start the stream, press again to stop. Pressing the button also turns on the LED backlight, so it’s obvious when streaming is in progress.

The tutorial

Aussie Federal Court Orders ISPs to Block Pirate IPTV Service

Post Syndicated from Andy original https://torrentfreak.com/aussie-federal-court-orders-isps-to-block-pirate-iptv-service-180427/

After successful applying for ISP blocks against dozens of traditional torrent and streaming portals, Village Roadshow and a coalition of movie studios switched tack last year.

With the threat of pirate subscription IPTV services looming large, Roadshow, Disney, Universal, Warner Bros, Twentieth Century Fox, and Paramount targeted HDSubs+ (also known as PressPlayPlus), a fairly well-known service that provides hundreds of otherwise premium live channels, movies, and sports for a relatively small monthly fee.

The injunction, which was filed last October, targets Australia’s largest ISPs including Telstra, Optus, TPG, and Vocus, plus subsidiaries.

Unlike blocking injunctions targeting regular sites, the studios sought to have several elements of HD Subs+ infrastructure rendered inaccessible, so that its sales platform, EPG (electronic program guide), software (such as an Android and set-top box app), updates, and sundry other services would fail to operate in Australia.

After a six month wait, the Federal Court granted the application earlier today, compelling Australia’s ISPs to block “16 online locations” associated with the HD Subs+ service, rendering its TV services inaccessible Down Under.

“Each respondent must, within 15 business days of service of these orders, take reasonable steps to disable access to the target online locations,” said Justice Nicholas, as quoted by ZDNet.

The ISPs were given flexibility in how to implement the ban, with the Judge noting that DNS blocking, IP address blocking or rerouting, URL blocking, or “any alternative technical means for disabling access”, would be acceptable.

The rightsholders are required to pay a fee of AU$50 fee for each domain they want to block but Village Roadshow says it doesn’t mind doing so, since blocking is in “public interest”. Continuing a pattern established last year, none of the ISPs showed up to the judgment.

A similar IPTV blocking application was filed by Hong Kong-based broadcaster Television Broadcasts Limited (TVB) last year.

TVB wants ISPs including Telstra, Optus, Vocus, and TPG plus their subsidiaries to block access to seven Android-based services named as A1, BlueTV, EVPAD, FunTV, MoonBox, Unblock, and hTV5.

The application was previously heard alongside the HD Subs+ case but will now be handled separately following complications. In April it was revealed that TVB not only wants to block Internet locations related to the technical operation of the service, but also hosting sites that fulfill a role similar to that of Google Play or Apple’s App Store.

TVB wants to have these app marketplaces blocked by Australian ISPs, which would not only render the illicit apps inaccessible to the public but all of the non-infringing ones too.

Justice Nicholas will now have to decide whether the “primary purpose” of these marketplaces is to infringe or facilitate the infringement of TVB’s copyrights. However, there is also a question of whether China-focused live programming has copyright status in Australia. An additional hearing is scheduled for May 2 for these matters to be addressed.

Also on Friday, Foxtel filed yet another blocking application targeting “15 online locations” involving 27 domain names connected to traditional BitTorrent and streaming services.

According to ComputerWorld the injunction targets the same set of ISPs but this time around, Foxtel is trying to save on costs.

The company doesn’t want to have expert witnesses present in court, doesn’t want to stage live demos of websites, and would like to rely on videos and screenshots instead. Foxtel also says that if the ISPs agree, it won’t serve its evidence on them as it has done previously.

The company asked Justice Nicholas to deal with the injunction application “on paper” but he declined, setting a hearing for June 18 but accepting screenshots and videos as evidence.
