The model takes web services in business process as protected objects and extends the classical RBAC model. Next, The software architecture of WS-RABC is presented. This paper also presents how to specify business process in the model and the authorization constraints of WS-RBAC based on WS-Policy.; Computer Science, Artificial Intelligence; Computer Science, Information Systems; CPCI-S(ISTP); 3
