TLMS: A Novel DRM Scheme for Multimedia Sharing in P2P Networks

A Three Layer Multimedia Sharing (TLMS) for managing access right of user in a P2P network is proposed in this paper. The features of TLMS include: 1) a novel DRM scheme for P2P networks, 2) a digital content protection without the need of an on-line server, and 3) low communication and computation cost. In addition to introducing the operation of TLMS model, we also compare its performance and security with Zhang et al's design in the context.
