A new technique has been developed for detecting and tracking illegal content transferred using the BitTorrent file-trading protocol. According to its creators, the approach can monitor networks without interrupting the flow of data and provides investigators with hard evidence of illicit file transfers.Contraband files might include pirated movies, music, or software, and even child pornography. When the tool detects such a file, it keeps a record of the network addresses involved for later analysis, says Major Karl Schrader, who led the work at the Air Force Institute of Technology, in Kettering, OH.The use of peer-to-peer (P2P) software and of the BitTorrent protocol in particular have increased steadily over recent years. In fact, for many Internet service providers (ISPs), the vast majority of Internet traffic now consists of P2P transfers.ISPs are generally only interested in detecting this type of traffic in order to control, or "throttle," it and free up bandwidth for other uses. However, this approach reveals nothing about the contents of each transfer, says Schrader. A handful of network-monitoring tools can identify specific BitTorrent files, but the process is generally slow, since the contents of each file have to be examined. The time that this takes also increases exponentially as the number of files that need to be scanned grows. More At; http://www.technologyreview.com/computing/22107/?a=f
