  • Existing commercial Digital rights management (DRM) schemes are not suitable for personal content protection because of centralized architecture and rigid constraints. To enable secure and flexible sharing of sensitive personal content, a new DRM scheme is proposed in this paper. Social trust between content sharers is modeled as computable concepts with DRM related contexts; based on the trust model, decentralized DRM architecture and scalable content sharing protocols are presented. Using the proposed DRM scheme, personal content owners can perform authentication and authorization without the intervention of Trusted authority (TA); by performing content sharing recommendations, authorized content users can conditionally have content shared with friends. Prototype implementation and simulation experiments indicate that the proposed scheme achieves satisfactory security and usability.
