Abstract

The present invention discloses a privacy protection-based social network location sharing method. When a location of a user is changed, multiple false locations may be generated, then the false locations and a real location of the user are sent to a location server by using a social network server; when a nearby friend location is being queried, the social network server inserts and sends a friend list of the user to the location server according to a request message of the user, and the location server may find the nearby friend location of the user, and send the location to the social network server; the social network server filters location information and forwards a final result to the user. The location sharing method provided in the present invention is independent of a third-party server, can effectively resolve a location privacy exposure problem existed in a conventional location sharing method, and has greatly practical value in social network application scenarios.
