Mission: Infiltrate the P2P Network

prostoalex writes "Wired News unveils the secrecy behind Overpeer, the company whose mission is to infiltrate peer-to-peer networks with low-quality audio and video files, or corrupted chunks of data which carry the same name and have the same size as originals. Apparently OverPeer even managed to procure a USPTO patent on (a) producing an advertising digital music file by deteriorating or damaging a sound quality of an original music file of a record of a cooperating record corporation; and (b) distributing the advertising digital music file through the communication network."

    or corrupted chunks of data which carry the same name and have the same size as originals.

    Isn't there some magical algorithm that produces an unique checksum number for a file, and if it were missing chunks wouldn't that reflect in that magical number? Don't most P2P networks use this magical MD5 checksum algorithm to ensure files aren't screwed up?

    Gee, you would think the patent office would realize they just awarded a patent to the same guy that sells server pixie dust.

      Of course you can calculate the MD5 checksum for every file, but you seem to miss the bigger picture. Taking the Linux kernel as an example:

      1. You check on ftp://ftp.kernel.org/ the MD5 checksum of the kernel you want to download.

      2. Find a mirror and download that kernel.

      3. Calculate MD5 on the downloaded file and compare it to the checksum from ftp://ftp.kernel.org/

      The problem with music files is that even if you start from the same CD so many different wav->mp3 converters can be used that it's impractical.

      but the client supplies the checksum. There's nothing to stop a client from sending a phony checksum.

      What if the content were divided into blocks. Each block has its own hash. As you are downloading the content, each block can be checked. As soon as you encounter a corrupted block, you blacklist that node.

      Really a trust based ratings system is going to have to be established. But in a way that it totally decentralized.

      This can be extended such that you download different blocks of a file from different nodes at the same time, thus getting the file sooner.

      In fact, what would happen if no single node had a complete file? This might not absolve you from copyright infringement though. So suppose that in order to form each block of the file, you actually had to download multiple blocks by their hash number, and XOR them together. Yes, it might take 3 times the bandwidth to download a file, but not necessarily 3 times as long in real time on a broadband connection.

      Now if Joe offers block 0x2857389298371987578392 of bytes that must be XOR'ed with two other blocks in order to produce the first block of the file, is Joe guilty of copyright infringement? But that same block might also be needed to reconstruct The Constitution of the United States, or the Bible or Moby Dick.

      The process of obtaining a file would be to first obtain a trusted list of the block numbers you need to obtain. Then you download those many blocks over the P2P system. The blocks you obtain may come from many different nodes. You just recombine them by mixing and adding water.

    What the are doing is essentially sabotage, and shooting themselves in the foot besides. Those persons who delivered us anartistic offal on CDs have merely found a way to do the same over P2P networks. The reason the recording industry is doing so poorly has nothing to do with the P2P red herring, but rather, is entirely due to a dismal lack of quality.

    It won't work well with all P2P networks. A prime example is the eDonkey network which uses a hash of each file as an identifier, not a filename/size identifier. You can rename the file to anything and the hash won't change. eMule Project is another great eDonkey network client and is open source.

    This is too little, too late, unless you're stuck on Kazaa.

  5. Cold War escalation... by Modern+Hamlet · · Score: 5, Insightful

    Tit. Tat.

    I might not like it, but this response seems pretty logical to me. The Industry has declared war on P2P as the source of their dwindling profits. (I'm not going to argue the validity, that's irrelevant.) Of course they're going to try to sabotage these networks any way they can.

    This puts the ball back in the court of the P2Pers. So what's the next step? Seems to me it won't take long for someone to come up with either a moderation system or IP blocking scheme that will force the Industry into a different line of attack.

    When are these people going to learn that if they spend 6 months developing a technology to "protect" their copyrighted info, it will take 6 days (if that) for someone to defeat it?

    Dime to donuts someone has a way to beat these bogus files within the week...

    "...And, in certain cases, we also may help them build relationships with potential customers who happen to be on the P2P site"

    "On some level they understand that P2P users are also potential customers -- record buyers, video renters or gamers -- and don't want to alienate them"

    Well if you want my business, then maybe you should give me a sample of what you have to offer, and not just waste my time in the first place. But then again, If I can buy a complete movie on DVD for even as low as $5 on sale, or $20 not on sale, why would I want to pay $18 for a CD with maybe 15 tracks if I'm lucky.

    Either way, these businesses need to figure out how to attract my attention, rather than ram their practices which are tried and proven to be not working, down my throat. Can't open my wallet that way!

    Another amazing fact was the mod of this post. You make a very broad statement. 'P2P is good for the world'. Why is that? I know why it is good for you and me. It make it easier for the technology haves to download the music, games, videos they love so much. but why is this good for the world? How does this help society in anyway? Don't get me wrong I think the level of crap produced by the Music industry is at epic levels. However, the movie industry and game industry have been producing some major pieces of work. Yea they may be over priced and poor people may not be able to afford them (but I bet these same people can afford a kick-ass system to run those games on).

    Or maybe you just wanted to try out the full game. Whatever. It don't matter. What makes this P2P good for the world?

    Nothing. Don't try to justify your behavior. You can't. It's like using drugs. You don't use them to make you a better person. You use them because you can and it's fun. So please, don't try to make yourself out as any better than the 'scum' that would try to stop you. There is no honor among thieves.

    The P2P concept is awesome. It is a great way to quickly exchange ideas, papers, shareware/freeware, etc. But when was the last time you downloaded anything other than copyrighted material from a P2P system?

    There are many ways of justifying actions other than through the morality of those actions. I don't read books to make me a better person, I read them "because I can and it's fun." Perhaps reading makes me a better person (sometimes yes, sometimes no), but that's not why I do it. Does that mean I can't justify reading? And yes, sometimes drugs can make people better, too. Recreational drugs can make people less tense, they can give people new perspective, they can introduce people to whole new worlds of experience. Do they do this for most who use them? Probably not. But there is more "honor among thieves" among recreational drug users than exists between record labels and their consumers.

    It's this puritanical stance that has really started to get me over the last few years. "Just because it's legal, doesn't make it right", true, but just because someone doesn't think it's right, doesn't make it so. Everything doesn't have to make the world a better place to have justification.

    That aside, I do agree with your thesis. "P2P makes the world a better place" is one of the most specious and nebulous statements I've heard in a great while.
