However, the mobile users in wireless network will constantly change their contexts. This traditional approach is not sufficient to protect modern digital contents in the complicated Internet environment or the wireless environment. In this paper, the FTA risk assessment of dynamic context access control for digital relics/museum content rights management is proposed. FTA is used to analyze the weakness of the DRM system. FTA helps us to know the information security requirement of the mobile digital relics/museum services. In order to satisfy the secure requirements, the watermarking, timestamp, RBAC, and the context access control are used to protect the digital relic content. The timestamp is stamped on the favorite relic and delivering the favorite relic to the viewer. The viewer can use operating right to view the favorite relic content. With our approach, it can offer an additional means for the definition and enforcement of the fine-grained context-dependent access control policies. This system authority can use the traitor tracing to revoke the usage license of the traitor and to catch traitors that leaks secrets. Furthermore, this approach reduces effectively the system weaknesses and the enterprise risk and decrease the production cost.
