为了统筹考虑web服务中信任评估与隐私保护的要求,提出了一种隐私感知的web服务信任模型,并给出了基于该信任模型的web服务选择机制,从而帮助用户在满足服务质量的基础上选择能更好地保护隐私的服务实例;设计了基于相关性的属性选择和权值确定方法,以使web服务信任模型更加通用,适应不同的应用环境;基于实测数据上的实验结果验证了所提信任模型的有效性. In order to consider the requirements of trust evaluation and privacy protection in web services, this paper proposes a privacy-aware web service trust model and gives a web service selection mechanism based on the trust model to help users meet the quality of service Select the service instance that can better protect the privacy; design the attribute selection and weight determination based on the correlation to make the web service trust model more universal and adapt to different application environments; based on the experimental results on the measured data, The validity of trust model.
