Integrating with practical e-commerce application,this paper introduces a novel multi-dimension evaluation method to depict and calculate the trust values.The multi-dimension evaluation metrics include functional and nonfunctional properties and corresponding weights.The continuous measurement values and the Markov chain mechanism are adopted to compute the trust value and detect the malicious behaviors.The current evaluation has larger influence factor on the next transaction behavior.A trust model is implemented with web service which consists of publication,filtrating,calculating and storage center.It is easily extended and the user only defines each property and its weights according to specific requirements,then the trust values are got.In order to conveniently manage and avoid the dead-lock,some constraint rules are proposed.The results show that the method based on multi-dimension can reflect objectively the dynamic change of trust values.
