Peer-to-Peer (P2P) networks have been widely used in various Internet applications. However, P2P networks also cause serious concerns of piracy of copyrighted contents: P2P helps to pirate copyrighted contents, which impedes wide application of P2P networks. In this talk, we study several important issues on the ways to prevent pirated content propagation in P2P networks. We build two mathematical models for BT attacks, including leechers behavior model and fake-block behavior model. We performe real-world experiments of attacking the existing torrents to evaluate its efficiencies. Piracy download time can be prolonged in most cases.
