Web服务组装中的隐私暴露分析方法

Research on Privacy Disclosure Analysis for Web Services Composition

保护Web服务用户的隐私已经成为目前服务计算领域的一个研究热点,但它们很少关注Web服务组装中的隐私暴露问题。针对上述不足,提出了一种Web服务组装隐私暴露分析方法。首先利用超图对服务组装隐私暴露进行建模,并给出了相应的转换方法。在此基础上提出了最小隐私暴露代价算法,利用该算法分析了隐私暴露最小的服务组装方案。最后通过实例说明了该方法的正确性及有效性。

Currently, to protect the privacy of Web services users is an important aspect of the research field for service computing. However, it is lack of research on privacy disclosure analysis for Web services composition. Based on improvement and expansion of existing related work, this paper proposes an approach for privacy disclosure analysis of Web services composition. Firstly, it models privacy disclosure for Web services composition based on hypergraph, and proposes a transformation method. Then, it gives an algorithm which can get the minimal privacy disclosure. Finally, it validates the effectiveness and correctness of the proposed approach through a case.
