Implementing Digital Right Management in P2P Content Sharing System

With the enrichment of digital content over the Internet, more and more people are using software for content sharing especially for multimedia content sharing, and most of these softwares are on the basis of P2P architecture which makes good use of high scalability and high efficiency. However, most P2P file sharing systems do not have security mechanism to protect intellectual property of authors and issuers. Moreover, it is difficult to control each peer's behavior due to its self-control principle and light-weight server. So we propose a new system based on P2P architecture for file sharing, to which we apply new DRM (Digital Right Management) mechanisms. Results have shown that our system outperforms other systems in features of security, server load and scalability.
