Abstract

Trust is an important problem in a community of interest (COI) built on top of service-oriented architecture (SOA). Furthermore, ranking services, data, and workflows in service-oriented applications is also important. This paper presents a role-based trust model to address these two problems. In this paper, users are classified into different roles in COI using role ontology (RO). The RO describes their relationships, and is used as a basis for assigning a numeric value as each role´s trust degree (TD). Because TD is represented as a number, the trustworthiness of service and data can be easily ranked in a COI system. Finally, this paper presents a case study to illustrate the key feature of this model.
