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 and what operations it must perform to accomplish its goals. We believe this PS combined with the presented metamodel provide a strong solution to providing privacy for SOA.
