Collusive Piracy Prevention in P2P Network
The primary cause of violation to intellectual property law is collusive piracy. Unpaid clients may get copyright contents from colluders illegally. Such kind of piracy causes to damage to content delivery in P2P network. The authors propose a system which prevents colluders from pirating the copyright contents in P2P.The firm idea to implement the system is to provide 4 level security mechanisms with Identity Based Signature (IBS).The proposed system helps to decrease the piracy without disturbing paid clients by sending unnecessary data i.e. poisonous chunks to violators. They propose Client authorization protocol (Cap) to differentiate unpaid client form paid ones. They are assigning time stamp to copyright content file which can be downloaded by paid clients exclusively. Based on simulation results, they find 90 percent prevention rate in Gnutella.
