The Application of RBAC in Digital Rights Management System

摘要：

Through further study on the characteristics of digital rights management system and the expansion of hierarchical role-based access control (RBAC) model, we proposed a context and hierarchical role based access control model and applied it to the digital rights management system. This model dynamically changes the permissions of users by obtaining context information related to security under complex network environment, and also can keep the advantages of traditional hierarchical RBAC model. This extended access control system is being implemented in practice, which makes the access control of digital rights management system become more flexible, safe and effective.
