Abstract

Location based system are used for discovering the point of interests (POI)s from a specific location based search on the user queries. The GPS latitude and longitude is sent as an input to the location servers which is based on the GPS coordinate with the point of interests and the current location of user can be served back to the client from the location server. This issue is characterized as tails: (i) a user needs to inquiry a database of area information, known as Points Of Interest (POI) s, and would not like to uncover his/her area to the server because of security concerns; (ii) the manager of the area information, that is, the area server, would not like to just convey its information to all clients. The area server longings to have some control over its information, since the information benefit for the location server. On the other concerns over how such possibly untrusted area servers can prompt client's private data revelation. This paper gives an exhaustive study of area based protection safeguarding, and present the different area security models and systems successful in the area anonymization based system.
