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.
To fulfill web service's requirements on trust evaluation and privacy protection, a privacy-a- ware trust model is put forward and a corresponding service selection mechanism is presented. They can help users to select the service providers which can provide better privacy protection besides service quali- ty. In addition, to increase the generality of the proposed model, a kind of method based on correlation for attribute selection and weight measurement is designed which can adapt to different application envi- ronments. Finally, through experiments on data from real environment, the effectiveness of the proposed model is validated.
