Web service has been widely used in the field of distributed application system. But the security issue of the Web service has often been considered as a crucial barrier to its application in many fields that conducts sensitive information. The proposed system presents a Context-Aware architecture for User Access Control model (CAUAC). Unlike traditional systems, in this access control has been explored and access decisions may depend on the context in which requests are made. It is illustrated and explained how the well-developed notion of roles can be used to capture security relevant context of the environment in which access requests are made.
