A Service-Oriented Trust Management Framework for E-commerce Systems

While the increasingly e-commerce provides enormous opportunities, it presents potential threats and risks because of lack of trust as well. Various trust management polices are proposed to improve these issues. However, most of these existing approaches only take into account a global attribute. The evaluation granularity is too coarse for customers to make an exact transaction decision. This paper proposes a service-oriented trust management framework for E-commerce systems. It consists of an authentication center, an evaluation controller, a reference controller, an update controller and a history controller. Considering the different services have different quality of service and content, our model evaluates a node under each separate service category, the evaluation result is more exact than some existing approaches and can reduce the risk of transactions. Finally, an example is given to analyze the feasibility and security of the model.
