The emergence of ubiquitous mobile devices, such as mobile phones, PDAs, and laptops, has sparked the growth of mobile web services. Unlike traditional identity/role based approaches for access control, access decisions for mobile web services will depend on the combination of the required attributes of user and the contextual information. As well as, it is crucial that the policy system can understand and interpret semantics of the context. This paper proposes a context-aware semantic-based access control model (called CASBAC) to be applied in mobile web services environment by combining semantic web technologies with context-aware policy mechanism. The proposed model adopts a context-centric policy method, and grants permissions to users according to current context information and allows high-level description and reasoning about contexts and policies. The model-theoretic semantics of CASBAC is an extension of the model-theoretic semantics defined in the OWL standard and SWRL.
