%X The current access control models are mostly static and coarsely grained; they are not well-suited for the service-oriented Web Services environments where information access is dynamic. In order to solve this problem, a role-based dynamic access control (RBDAC) model for Web Services was proposed. The RBDAC model can activate role assignments and permission assignments based on context information, and make access control decision dynamically.
