摘要
A copyright protection system for large scale content delivery over peer-to-peer P2P networks is disclosed. The system may integrate the complementary protections of a peer authorization protocol (PAP), selective content distribution and poisoning, and peer collusion detection. The system may include a transaction server computing system coupled to a P2P network and configured to enable users on the P2P network to conduct transactions for acquiring digital content to thereby become authorized clients for the digital content; and a plurality of distribution agent computing systems coupled to the central server and the P2P network, each distribution agent configured to store and distribute said digital content to said authorized clients distinguish authorized clients from unauthorized peers using a peer authorization protocol (PAP), selectively distribute poisoned versions of the digital content to unauthorized peers while distributing the digital content in a clean form to the authorized clients, cause a random plurality of the authorized clients to send download requests for a copyright protected file to other peers suspected of being unauthorized, receive, from one or more of the suspected other peers, clean copies of the file in response to the download requests; and identify the one or more suspected other peers as unauthorized peers.
