摘　　要：为实现对移动群智感知中隐私信息的保护,解决请求者在云端监听,请求者与诚实且好奇的云相互串通导致用户隐私信息泄露的问题,提出一种基于云辅助的隐私信息保护机制。通过对用户贡献的数据进行拆分重组,使敏感数据脱敏,利用同态加密对拆分后数据进行处理,防止隐私信息的泄露,使移动用户可以安全地参与感知过程,保护请求者的权益。模拟实验结果表明了所提方案是可行有效的。To protect the privacy information in the mobile crowd sensing(MCS),and to solve the problem that the requester listens in the cloud,or the requester colludes with the honest but curious cloud,which causes the user privacy information to leak,a cloud-assisted private information protection mechanism was proposed.The data contributed by the user were splited and reorganized to desensitize the sensitive data,and the homomorphic encryption was used to process the split data to prevent the leakage of the private information,so that the mobile user safely participated in the sensing process while protecting the rights of the requester.Results of simulation experiments show that the proposed scheme is feasible and effective.
