Efficient K-Nearest Neighbours Discovery using Complex Secure Evaluation Function in Geo Tagged Dataset
K. Manoj, B. Tarakeswara · International Journal of Computer Applications · 2015
The materialization of mobile equipment with fast Internet connectivity and geo-tagged capabilities has led to a revolution in personalized position-based services where clients are enabled to admittance information about points of interest that are pertinent to their interests and are also close to their geo tagged coordinates.The important type of queries that absorb location attributes is symbolized by nearestneighbor queries, where a client wants to retrieve the k-Point of interests that are nearest to the user's current location.Entities specialized in various areas of interest and gather large amounts of geo-tagged data that appeal to subscribed users.In this paper the proposes development and implementation of frame work to provide more complex protected evaluation method on cipher texts, like skyline queries and security protection guarantees against the client, to prevent it from learning anything other than the received k query results.
