Researchers Outline Targeted Content Poisoning For P2P Data

Diomidis Spinellis writes "Two USC researchers published a paper in the prestigious IEEE Transactions on Computers that describes a technique for p2p content poisoning targeted exclusively at detected copyright violators. Using identity-based signatures and time-stamped tokens they report a 99.9 percent prevention rate in Gnutella, KaZaA, and Freenet and a 85-98 percent prevention rate on eMule, eDonkey, and Morpheus. Poison-resilient networks based on the BitTorrent protocol are not affected. Also the system can't protect small files, like a single-song MP3. Although the authors don't say so explicitly, my understanding is that the scheme is only useful on commercial p2p distribution systems that adopt the proposed protocol."

    Poisoning the well. What an insightful revelation. Surely it's never been done before, maybe they should throw a patent on it.

    'mechanical law of nature'

    I don't think that phrase means what you think it means.

    Exactly, just go to YouTube and you will see the DMCA abused left and right. (Well, and if you read the comments page you will find the rules of spelling, rules of actually saying something along with the rules of grammar and common sense to be abused too....)

    These guys are from USC, not UCLA. As a UCLA graduate, I am extremely upset that anyone would make this mistake. USC students and professors are smelly, unclean, spoiled children who work for the RIAA. UCLA students and professors are the opposite.

    Never, EVER, confuse us again.

    of COURSE they aren't real researchers. The summary writer mistakenly thought the study authors were from UCLA, which would mean they would have been some of the smartest, unbiased, amazing people in the world. However, they were actually from USC, meaning they were spoiled, unprofessional, RIAA lapdogs who also smell.

    And yes I happened to go to UCLA, but that is besides the point.
