A Review Paper on Security Wall: Resisting Unauthorization in Geosocial Network

Online Social Network has become a predominant source of information wherein users of all ages readily provide their personal information. With the advent of geosocial networks like Foursquare, Yelp assembles minute and detailed information of its registered users at various geographic locations which can be said as venues. Applications like targeted advertisement, personalized recommendations can be provided by the geosocial network with the help of the personal information aggregated by the users visit at a venue. This may lead the user towards a significant risk, if their personal information is somehow leaked or sold. Hence we provide a novel approach of building Location Centric Profiles (LCPs) of current users in a secured way and also proving its location correctness where users can modify LCPs in a predefined manner only.
