Semantic Web services have brought great convenience to service-oriented software development. However, during the semantic Web service composition because the component Web services and licensing issues often require repeated dynamic binding, which greatly affect the efficiency of the service execution. To address this problem, we propose a defeasible policy based access control approach for semantic Web service composition. Firstly, before the semantic service is bound to a component of Web services, static analysis can avoid unnecessary service binding in the semantic Web service composition and execution time. Then we give the access control enforcement process in composition and execution time. Finally, the feasibility of this method has been verified through experiments. Our approach can increase the efficiency and successful rate of semantic Web service composition.
