We propose a novel location-privacy preserving mechanism for TTP using hiding original location. To take advantage of the high effectiveness of hiding user queries from the server, which minimizes the exposed information about the users' location to the server; we propose a mechanism in which a user can hide in the mobile crowd while using the service. The rationale behind our scheme is that users who already have some location-specific information (originally given by the service provider) can pass it to other users who are seeking such information. They can do so in a wireless peer-to-peer manner. Simply put, information about a location can “remain” around the location it relates to and change hands several times before it expires. Our proposed collaborative scheme enables many users to get such location-specific information from each other without contacting the server, hence minimizing the disclosure of their location information to the adversary. Proposed system avoids the privacy problems of users by collaborate with each other to jointly improve their privacy, without the need for a trusted third-party. In effect, the mobile crowd acts as a TTP, and the protection mechanism becomes a distributed protocol among users. Desktop users concerned about their location privacy are indeed the most motivated to engage in protecting themselves.
