The usage control which involves traditional access control, trust management and digital right management is a comprehensive model. For the reasons included high abstract and the authorization hard to be managed, a new model was putted forward to administrate usage control mode1—RUCON model. Six functions of authorizations, which are user-role auto-assignment based on role-rule, role-hierarchy assignment, permissions -role assignment, usage-rule, obligations and conditions were defined in the new model. In order to simplify the management the new model adopted the advantages of the RBAC model. In the RUCON model the assignment and revocation of right are administrated automatically through the medium of roles. The formal description of the RUCON model was given as well.
