Application of the Extension RBAC Model in the Family Open Platform

Role-based access control（RBAC）technology is one of the hotspots in the research of access control.It is of great flexibility and high efficiency.The permission of RBAC model was refined,and four elements such as object,action,domain and group were added to the model.The inheritance of domain was put forward.The extended model（ODG-RBAC）provided a more fine-grained access control.Through using ODG-RBAC model in the family open platform STB manage system,the problem of access control was resolved.Meanwhile,by providing diversified design scheme of permissions and roles,the complex responsibility assignment was implemented.
