摘要 针对基于位置的服务中社交位置的攻击问题,提出了一种基于协作的社交位置隐私保护方案,用来保护附近社交用户的位置。在现有的位置隐私保护技术的基础上,总结了现有位置隐私保护技术中优点和不足,给出了基于和社交好友的协作进行社交位置隐私保护的方案。在此方案中,社交好友在基于网格的环境内,利用网格的翻倍扩增来计算匿名区域。理论分析和仿真结果表明,该方案能有效用于附近社交用户的位置隐私的保护。 To protect social location from being attacked,a cooperation-based privacy protection scheme is proposed. The advantages and limitations of existing location privacy protection technologies are summarized and a privacy protection scheme based on cooperation with social friends is put forward.In the scheme,social friends use the amplification of grid to calculate the anonymous area in grid-based map. Theoretic analysis and simulation results prove that the scheme can effectively protect the location privacy of nearby social users.
