Privacy protection is still a key challenge in the Web service composition area. The user and Web service provider frequently share their privacy data with other Web service will increase the risk of misuse and disclosure of privacy. In this paper, we first analyze the privacy protection problem according to define four types shared data within Web service composition, and then present Web service composition and privacy models, our models allow user and Web service provider to define user´s privacy preference and Web service´s privacy policy specification. An algorithm is presented to check the policy compliance on the dependency edge and select a set of policy compliant Web services with compositing a well privacy protection Web service composition. Experiments demonstrate the applicability of our models and algorithm.
