Historically, information security in the form of secrecy, integrity, and authentication is applicable for any personal computer systems and information dissemination networks. Mobile computing represent a new computing class consisting of large numbers of mobiles and base stations deployed at different geographical regions. Due to advancement in mobile technology users are able to share their location with each other. This leads to new security problems. Hence it is necessary to develop protocols to provide privacy. We provide a novel personalized location privacy model for mobile network in which location information of the target is preserved and made available to other user belonging to different groups depending upon the privacy level defined by the target by making use of trusted middle party between user and location server called as location control centre. User can query anything to Location Based Server (LBS) like nearest Point of Interest (POI) or location information of a friend, LBS provides response to user by taking information from location control centre. User can define privacy levels for different spaces, groups and store it at Location Control Centre (LCC). Location information of a target user depends on in which space he is currently present or whether for a particular time slot target’s location is blocked. Depending on this location control centre provides location information to LBS and LBS respond back to user. All the data transfer is performed in encrypted form and decryption is done on client side. For this key management is done by location control centre.
