Abstract
Abstract: Privacy based Context-aware systems based on location open up new possibilities to users and data servers in terms of acquiring custom services by gathering context information, especially in systems where thehigh mobility of users increases their usability. Location-based applications utilize the positioning capabilities of a mobile device to determine the current location of a user, and customize query results to include neighbouring points of interests. However, location knowledge is often perceived as personal information. One of the immediate issues hindering the wide acceptance of location-based applications is the lack of appropriate methodologies that offer fine grain privacy controls to a user without vastly affecting the usability ofthe service. In this paper, novel approach is proposed as a solution to one of the location-based query problems through Privacy preserving based Context Reputation System. The Solution of the System is as Follows, a user wants to query a database of location data, known as Points of Interest (POIs) with respect of protecting their location Information against data leakage. Similarly the owner of the location data, that is, the location server, does not want to simply distribute its data to all users. The location server desires to have some control over its data, since the data is its asset, hence security mechanism named as shared Authority is employed against data sharing also data is reputed based on the reputation mechanism . The solution is efficient and practical in many scenarios. By implementing the solution, it is possible to access the efficiency of the protocol and proposed introducing a security model and analysing the security and reputation of the context of protocol will improvethe performance of the system.
