Danmei Niu, Zhiyong Zhang, Lili Zhang · 2010
The purpose of DRM (Digital Rights Management) is to prevent from the illegal copy and distribution of digital contents. DRM technology could be used in home network, but in many situations, different users need different access rights to DRM contents in home network. The paper presented a DRM system for home network based on RBAC (Role-Based Access Control) and license chain. A DRM functional architecture for home network was shown, then the partition of roles and permissions for home network was made based on RBAC. Moreover, the working process of the system was put forward, and the system analysis was made. Finally, a conclusion was drawn and the future work was addressed.
