Trusted Mediation for E-service Provision in Electronic Marketplaces
- 616 Downloads
From a commercial viewpoint, the Internet is evolving from a collection of web sites for advertising products to an open and distributed environment for service provision. Electronic marketplaces represent the mediation contexts where service providers and service consumers can interact to carry out their business transactions. In electronic business relationships the issue of trust becomes central, and its enforcement is a fundamental value that electronic marketplaces can offer to their members. The paper focuses on trusted contract enforcement in the context of an electronic marketplace infrastructure. In particular, it describes the model and the component for mediated service delivery developed at the HP labs in Bristol. The presented solution is based on the concept of externalisation for service consumer views of the business processes of service providers.
