摘要：Cloud computing provides elastic, scalable on-demand IT services for individuals and organizations. In the cloud computing, everything is as the service. Cloud clients enjoy convenience and efficiency service, but at the same time encounter new issues. Cloud clients needs to provide authentication information to access to service, which often contains a lot of sensitive information. The service provided by Cloud is dynamic, diverse, and context-related. The traditional identity authentication methods which implement coarse-grained to allow or prohibit access is no longer to adapt service-oriented cloud computing. In this paper, we propose a service-oriented identity authentication privacy protection method. In the method, we define cloud service access control as a process and extending the cloud client related information into a fuzzy set as the authentication condition for the exchange, according to the amount of information security level, dynamic opening the corresponding service access control and providing fine-grained service-oriented identity authentication, guarantees global minimal sensitive information disclosure, and maximally protects individual privacy
