基于 P2 P网络模型的Web搜索引擎用户隐私保护

摘要

For the issues that user privacy violations in WSE,this paper proposed a user privacy protection scheme in WSE based on P2P network model.It used P2P network architecture to group the users according to their interests,and the con-struction of multilayer privacy protection mechanisms.The user query was submitted by nodes forwards,WSE could only ob-tain brief characteristics of queries and provide the corresponding services.At the same time,this scheme protected the honest users,and exposed the selfish users to WSE.Experimental results show that the proposed scheme can protect user privacy well and provide good service quality.%针对网页搜索引擎（Web search engine，WSE）中存在侵犯用户隐私的问题，提出一种基于P2P网络模型的WS E前端用户隐私保护方案。利用P2 P网络架构来将用户根据他们的爱好进行分组，并构建多层隐私保护机制，通过节点转发来提交用户查询，WSE只能获得一组查询的简要特征并提供相应的服务；同时保护诚实用户不被WSE暴露，并将自私用户暴露给WSE。实验结果表明，该方案能够很好地保护用户隐私，并提供良好的服务质量。
