The composite services of application layer have the attribute of evolution in cloud computing. Therefore, in the process of service composition, the user private data may be disclosed because of the evolution of services or service flow. Considering the evolution character of the composite services, based on the description logic, this paper proposes a privacy protection method, which is orienting the evolution of application layer. The privacy policies are described with the formal method. Secondly, according to the evolution character of the composite services, the running of the composite services is monitored to satisfy the users privacy requirements. In the end, the correctness and feasibility of this method are demonstrated through case study.

Key words: cloud computing, composite service evolution, privacy protection, evolution monitoring
