P2P (Peer-To-Peer) applications have enormous success in information sharing, although there exist illegal distributions of copyright-protected works (music, games, video streams, etc.) and anonymous malicious attacks. These abuses have resulted in heavy financial loss in media and content industry. Collusive piracy is the main source of intellectual property violations within the boundary of P2P networks. This problem resulted from paid clients (colluders) illegally sharing copyrighted content files with unpaid clients (pirates). Most P2P networks in use do not provide any function of Digital Rights Management (DRM) and are always blamed for illegally sharing copyrighted contents.
