A reputation pattern for service oriented computing

Trust problems exist in open distributed service oriented computing environments. A lot of research work has been done on the theories and applications of trust and reputation management in service oriented environment. However, the design expertise on trust is not well documented yet. In this paper we propose to use trust patterns for documenting solutions for trust problems. The main benefit of using trust patterns is that it decouples the application domain expertise from the trust expertise. We also present a reputation service pattern as a solution to the trust problem in service provision which is one of the significant problems in service oriented computing environments.
