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 chapter, the authors further define a metamodel for privacy policy creation and comparison. A trust element is developed as an additional criterion for a privacy policy. The authors define the PS, outline what operations it must perform to accomplish its goals, and present how the PS operates in different scenarios. They believe the PS, combined with the enhanced metamodel, provides a strong solution for providing privacy in an SOA environment.
