Research on Secure Digital Content Distribution for Peer to Peer E-Commerce Applications
To resolve network congestion and other problems in electronic commerce (e-commerce) applications, such as digital content distribution in e-commerce, the e-commerce applications distributed systems based on the traditional paradigm are nowadays replaced by peer-to-peer (P2P) systems. Peer to peer technology has a lot of advantages for ecommerce applications especially in digital content distribution field. For commerce applications, the security and P2P rights management become more and more urgent. New schemas and solutions for P2P e-commerce applications security and right management, which are expected to function automatically or semi-automatically, should be proposed. In this paper, a secure digital content distribution scheme is presented, which can trace illegal distributors in Peer to Peer e-commerce applications. In this scheme, the encrypted content is decrypted into different copy under the control of a fingerprint and encryption key at the peer side. Thus, each decrypted media copy contains unique information that identifies the peer. For the decryption operation and fingerprint embedding operation are combined together, which avoids the leakage of clear media content. Additionally, these operations are implemented by the peer, which makes the scheme compliant with existing Peer to Peer Digital Rights Management (DRM) systems and very proper for P2P digital content distribution e-commerce applications, performance evaluation is also included.
