一种移动社交网络中的位置内容分享方法
Location content sharing method in mobile social networks
摘要
Abstract
Aimed at the problem of multiple user location privacy in mobile social networks,a cooperative access control model based on trust is proposed at the level of access control.The conflict resolution method based on concession willingness is given among multiple users to achieve a balance between the privacy protection and the sharing degree.According to the problems of untrustworthy friends' malicious forwarding,a control method,called the ‘refuse to be covered’ is studied to support the user in setting the number of forwarding hops and controlling the range of sharing.In the case of LBS location privacy protection,a dummy location selection algorithm based on the greedy algorithm is proposed to prevent the service provider from obtaining the sensitive location of the user,in which the constructed dummy location set can guarantee the maximum entropy and the maximum cloaking region.Experimental results show that the algorithm is available.关键词
