Manu. P. Krishna, Jose Hormese

By tremendous improvement of pinpoint localization, more number of geo-social applications are used by millions, which gives an opportunity to interact, also sharing locations to unknown. However today’s geo-social application have many privacy issues, which can easily misused by an expert even a well known person. LocX is a latest technique used for providing security in geosocial application. In LocX working scenario, Location coordinates are transformed before updating to server. User must exchange their secret key prior to location sharing , . Medium of sharing key is via mail or messages. This mechanism is not suited for high end geosocial applications. One user can hold the secret key of his N friends. LocX is efficient but not a novel method, for reduce the complexity a new technique for Location privacy is introduced ,using attribute based encryption instead of sharing secret keys. By adopting this way, it provides performance overhead and ease of use.
