A Proposed Piracy Prevention Technique in P2P Network

Collusive piracy is first and fundamental cause of violation to intellectual property law. Illegally unpaid clients would get copyright contents from colluders. Such type of piracy causes to destruct to content delivery in P2P network. Proposed system aims to prevent colluders from pirating the copyright contents in P2P. The fundamental idea behind implementation of the system is to provide a security mechanism with identity based signature (IBS) and content poisoning technique. The proposed system assists to reduce the piracy percentage without disturbing paid clients by sending unnecessary data i.e. poisonous chunks to violators. Proposal to make Legal Client Authorization Protocol (LCAP) is to differentiate unpaid client form paid ones. Unique time stamp will be assigned to copyright content file which can be downloaded by paid clients exclusively. Based on simulation results, it is found that 90 percent prevention rate in Gnutella. These P2P-based CDNs gives very fast delivery speed, higher content availability and cost-effectiveness than traditional CDNs built with huge network of surrogate servers
