Peer-to-peer 'seeders' could be targeted
BayTSP, based in California, US, monitors peer-to-peer (P2P) trading networks using a technique called software "spidering". The new software, called FirstSource, allows it to determine which user first uploaded a particular file for trading. It does this by mimicking the behaviour of a user on a massive scale - sending out multiple requests for a file extremely quickly. It deduces the culprits by assuming that only they will have the full 100% of the file, having uploaded the original.
Graham says FirstSource could enable copyright enforcers to focus their legal attacks against those who are at the root of illegal distribution.
Adam Langley, a UK-based P2P programmer adds that network developers could also modify their software to get around such monitoring.
"I suspect it would only require a trivial modification to render this technique useless," adds Ian Clarke, who is one of the programmers behind an anonymous file-trading network called Freenet. Freenet makes it impossible to tell who requests a file by encrypting data and communications and distributing between multiple sources.
