The emerging location-detection devices together with ubiquitous connectivity have enabled a large variety of locationbased services (LBS). Location-based services are becoming popular for mobile users. The mobile users’ location plays a key role to provide the service from one side, but it can be considered as a dimension of their privacy and so necessary to keep it anonymous to the other part...

Location-based social discovery (LBSD) services enable users to discover their geographic neighborhoods to make new friends. Original LBSD services were designed to provide the exact distances to nearby users. It has been shown that it is easy to pinpoint any target user’s location by using trilateration based on the exact distances from three fake Global Positioning System locations to the tar...
