Introduction of mechanisms that resourcefully defend user privacy devoid of sacrificing accurateness of the system, or making tough assumptions in relation to security of application servers is the challenge faced in recent times. The authors aim geo-social applications, and suppose that servers can be compromised and, as a result, are untrustworthy. Their intention is to build a system that enables users to query for friends' information on basis of locations, while defending their location privacy. In this paper, they put forward LocX, location to index mapping which is a novel method to attain user privacy while sustaining complete accuracy in location-based social applications.
