A Privacy Service for Comparison of Privacy and Trust Policies within SOA

Privacy for Service-Oriented Architecture (SOA) is required to gain the trust of those who would use the technology. Through the use of an independent Privacy Service (PS), the privacy policies of a service consumer and provider can be compared to create an agreed upon privacy contract. In this paper we further define a metamodel for privacy policy creation and comparison. A trust element is developed as an additional criterion for a privacy policy. We define the PS, outline what operations it must perform to accomplish its goals and present how the PS operates in different scenarios. We believe the PS combined with the enhanced metamodel provide a strong solution for providing privacy in an SOA environment.
