Omnify: Investigating the Visibility and Effectiveness of Copyright Monitors
The arms race between copyright agencies and P2P users is an ongoing and evolving struggle. On the one hand, content providers are using several techniques to stealthily find unauthorized distribution of copyrighted work in order to deal with the problem of Internet piracy. On the other hand, P2P users are relying increasingly on blacklists and anonymization methods in order to avoid detection. In this paper, the authors propose a number of techniques to reveal copyright monitors' current approaches and evaluate their effectiveness. They apply these techniques on data they collected from more than 2.75 million BitTorrent swarms containing 71 million IP addresses.
