Abstract

P2P content sharing is often blamed for copyright infringement, making the establishment of DRM technologies an urgent need. A PDRM (P2P- based Digital Rights Management) system is proposed with the support of Next Generation Internet Project. The system is based on a trust model that focuses on content security, rights management and access control. Encryption, digital watermarking, and packaging technologies are adopted to protect the confidentiality and integrity of contents, and support copyrights verifying and piracy tracing. The structure of rights management integrates the distributed and centralized modes, which not only reduces the burdens of networks and rights server, but also provides controllability. The contents downloaded on the P2P networks can be played only with rights control. To realize access control, the password and identity authentication are used. The PDRM system is implemented to prove that it can provide a more robust Intellectual Property protection solution for P2P content delivery.
