Email this article Location Privacy And Geo Based Applications
Abstract
— Using Geo-social networking like Apple's i Groups and Hot Potato, many people communicate with their neighbouring locations through their associates and their suggestions. Without sufficient location protection, however, these systems can be easily misused, in this paper, we introduce, a technique that provides location secrecy without adding complexity into query results. Our idea here is to secure user-specific, coordinate conversion to all location data shared with the server. The associates of a user share this user’s secret key so they can apply the same conversion. This allows all spatial queries to be evaluated correctly by the server, but our privacy mechanisms guarantee that servers are unable to see or infer the actual location data from the transformed data or from the data access.
