Abstract:

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

摘要:

云计算应用层中的组合服务具有演化属性,因此,隐私数据在服务组合过程中,用户的隐私数据可能会因为服务或服务流程的演化而暴露。根据服务演化的特征,以描述逻辑为基础,提出了一种面向云计算应用层演化的隐私保护方法。对隐私协议进行形式化描述;根据服务的演化特征,对服务的演化进行监控,保证满足用户的隐私需求;利用实例研究证明该方法的正确性与可行性。
