%X In order to improve and enhance the efficiency of role-managing and permission-assigning of traditional RBAC,an expanded model of RBAC based on isomorphic adapter-monitor of objects'states is proposed,which associ- ates roles and corresponding permission while objects are in different states.When the states switch and accordingly al- ter the assignment of roles and permission,with Observer Pattern,the adapter-monitor can catch it in time,response it automatically and then adapt it dynamically,to avoid acces...
