一种基于风险和推荐的用户信任计算方法

A computing method of user trust based on risk and reputation

结合客观的风险评估和主观的推荐信任共同计算用户可信度,并利用推荐可信度和域可信度来识别和惩罚提供虚假反馈的服务方,提出了基于风险和推荐的用户信任计算方法。仿真实验表明,该模型具有较好的动态适应性,能够准确反映用户行为,为信任决策提供安全、可靠的依据。

We calculate the user reliability jointly with objective risk evaluation and subjective reputation trust. And the server which provides inveracious feedback can be identified and punished by reputation reliability and field reliability. This paper propos- es a computing method of user trust based on risk and reputation. The experimental results show that the proposed model has good dynamic flexibility and reflects the activities of entities accurately. This method provides secure and reliable basis to trust decision.
