AT&T Invests in Filtered Networking

Posted by CowboyNeal on Fri Nov 16, 2007 12:49 AM
from the dark-futures dept.
Filtered Coward writes "Last summer, AT&T announced its intention to begin filtering copyrighted content at some point. The telecom has now bought a chunk of Vobile, whose core product is VideoDNA. "Like other systems of its kind, VideoDNA develops a unique signature from every frame of video. The signature is meant to be robust enough to survive various transformations and edits, and it can then be used to run matches against incoming content.' Vobile claims that VideoDNA is good enough to be used on video when transmitted over a network. 'Based on the complexity of the problem, we suspect that anything initially deployed by AT&T will fall far short of a robust P2P video filter. But should AT&T truly have its eyes on just such a prize, the company would be in a powerful position to impose its own policies on the entire US, since it owns major parts of the Internet backbone.'"

[+] Your Rights Online: MPAA Boss Makes Case for ISP Content Filtering 282 comments
creaton writes "At the annual UBS Global & Media Communications Conference yesterday, MPAA boss Dan Glickman banged on the copyright filtering drum during a 45-minute speech. Glickman called piracy the MPAA's #1 issue and told the audience that it cost the studios $6 billion annually. His solution: technology, especially in the form of ISP filtering. 'The ISP community is going to be at the forefront of this in the future because they have everything to lose and nothing to gain by not seeing that the content is being properly protected ... and I think that's a great opportunity.' AT&T has already said it plans to filter content, but others may be more reluctant to go along, notes Ars Technica: 'ISPs that are concerned with being, well, ISPs aren't likely to see many benefits from installing some sort of industrial-strength packet-sniffing and filtering solution at the core of their network. It costs money, customers won't like the idea, and the potential for backlash remains high.'"

    This seems to imply that copyright-infringing video is being streamed over the network. Does this ever happen? More likely it is broken up into completely arbitrary chunks, which may or may not contain an entire frame and are unlikely to be delivered in sequential order. Furthermore, any form of network or P2P encryption currently in use ought to be able to defeat this. I wonder how much AT&T will be spending on this plan?
    • Bittorrent already has good encryption yeah.. and something like 25% of people have it turned on in the US and close to 80% of people in the UK.

      As soon as this absurd technology starts working (if ever) everyone will turn on the encryption.

          This is AT&T. They don't distinguish, they just give it all to the NSA, as demonstrated by the lawsuits filed by the EFF and the whisteleblower who revealed the taps on core fiber optic backbones.

          The NSA, now, has fairly good tools. There's a fascinating tool from a company called Sandstorm that re-assembles network traffic into its distinct streams and does quite a good job of re-assembling email and web transactions. Given a remote opportunity to do a man-in-the-middle SSL key replacement, or simply steal the SSL or SSH keys from the serving host (with or without a subpoena), such tools could doubtless do quite a good job of intercepting transmissions seamlessly. And innocent folks aren't bothered to go to that level of protection, such as using obscure languages or real one-time pads.

          Like the phone company's wilingness to tap phone conversations from the telephone offices, undetectably, because it's merely duplicating the digital bits and sending them to whomever they care to send them to, such monitoring constitutes a massive risk to the innocent for political and illegal monitoring. We see what such monitoring and related censorship does in China right now: we need to be extremely wary of it occurring here with such tools casually accepted.
          • I tried to create my own one time pad by XORing the Windows install CD with the Ubuntu install.... My computer burst into flames...

    Encryption can beat this, but should it have to? Now we've got to throw a lot of computing power at a problem just to get around our nominally "common carriers."

    I think we can all agree that there's a problem: lots of illegal video transmission is happening online. And while some of the slashdot crowd consists of "information wants to be free" hippies, there is also a good community of people who reasonably understand the value of intellectual property rights. But I don't think anyone is excited about a solution like this, which clearly removes the user's fair use rights and common sense.

    So where's the balance? Can a technical solution exist that will simultaneously stop the illegal pirating of movies and TV shows (which would be good), and allow other uses (even short clips, parodies, etc)? I think the answer is no. The determination of fair use relies heavily on intent, and no technical system will be able to determine that very effectively.

If a person makes a phone call or uses a bulletin board to commit a crime, the teleco is not part of the conspiracy. They are neutral. If AT&T starts filtering out "criminal" activity (and what jury of peers determined that anyhow?!), then are they giving up their neutral status? If they try to filter any material, will they be liable for all the material that inevitably slips through their net?

    Allows you to fairly use content in a situation which merits it, for example:
    * Educational material
    * Parodies
    * Licensed use
    * Short clips
    * Lots of others

    I'm not in the USA, but say for example I own a hard copy of a movie or TV show on DVD, am I "allowed" to stream it from home during my lunch break or after work when this system is possibly live?

    Remember, if they are doing filtering it means they are no longer a common carrier, what is the legality of this in regard to third party content; if I were to transfer illegal content over their connection will they be liable for this because they haven't filtered it out? Or will the law apply to them when it suites em.

    There are so many holes in this I couldn't possibly see this implemented, not to mention the resources that'd be required on their end to keep up with the constant change in codecs/compression methods and to be able to decode it in realtime.

    Yeah, it's just speculation at the moment, but in a really dark and unfunny way I can see PHBs combined with RIAA/MPAA mafia seriously pushing something similar based on their draconian previous tendancies.

    Dear AT&T,

    I have been a voice customer with you for many, many years, and I have chosen to get my internet service from you in the days of yore - 1996, with a 56k modem, and four years later, I upgraded to your residential ADSL product. I've always been content with your service - sure, the random two-hour downtimes at 1 AM every four or five months piss me off, but I understand that sometimes, you just gotta do it.

    I've done my part in being a loyal customer; I only call when I'm sure the problem lays beyond my DSL modem, I don't torrent often, and I've never tried to do anything shady to your other customers. Over the past decade, you've treated me well by not blocking inbound port 80 traffic. That's why I haven't ever moved to a much faster Cable connection. Hell, I even work for a CLEC and if I was so inclined, I could have a free 1.5 SDSL line - but I haven't done that because you've given me no reason to go through the hassle of set-up.

    You might have spied on me. Don't get me wrong - I'm plenty pissed off about that. But I know it wasn't anything personal. I know how upper management can be when the NSA comes knocking. The way things are going, I think you'll ultimately answer to us for what you did, so I won't stress too much about it. Anything important is encrypted, anyways.

    But now, my dear AT&T, for the first time in a decade, I don't know what to think about you. Your problems with torrenting and streaming video are that you don't have enough bandwidth to accommodate all of your customers. You've grossly oversold your network's capacity, just like my company does, and now you're being bit for it. It's an unpleasant situation for you - trust me, I know exactly how that feels.

    But now, how many billions are you going to spend on this fingerprinting system for video? How many people will work on this project? How many legitimate packets of mine is this going to slow down or drop? And, in the first week this system goes live, won't everybody just turn crypto on and use YouTube over https? Billions of dollars...flushed right down the toilet in an instant!

    Now, as I said, I'm just a humble legacy customer. I started out at SNET, then get assimilated into SBC/Yahoo, finally ending up as a customer of the Great Bell Company. But, might I, a meek twice-legacy customer, suggest that you ax this project and ***invest the fucking money in buying more fiber, thereby solving the actual problem***?

    I mean, come on. What the fuck do you care if people are stealing the latest blockbuster using your network? You're not in the business of being moral guardians, and there's no way in hell a court would ever hold you liable for something like this.

    Just know, my old friend, that if you do end up implementing this, the first time one of my packets gets dropped mistakenly, you damn well better believe I'll take my company up on that free SDSL line. And I'll be living here for a long time to come.
