Abstract

Web services collaborative environments are highly automatic, dynamic, heterogeneous, and full of cheating. These characteristics always lead to high risks of the services for the interaction participants. Hence, to guarantee that the private data in Cross-Organizational collaborative applications are not illegally collected and disclosed becomes a key for implementing the security services collaboration. In order to improve the reliability of the system, it is necessary in privacy-aware Web services collaboration systems to verify whether the implementation of a set of services satisfies the requirement specification of the system. This paper proposes a role-based privacy-aware Web services collaborative model, which delegates the privacy authorization based on trust relationships of services and then presents algorithms to make the consistency verification between the requirement specification and the implementation services. Finally, this paper verifies the correctness and efficiency of the role-based approach through an application example.
