Abstract
Advances in network technologies and continuous growth of the Internet have triggered a new trend towards outsourcing data management need Service Providers. Outsourcing spatial database includes third party Service Providers which has attracted much attention from the individual and business data owners. With the popularity of mobile devices, it provides immediate and reliable location based information to smart phones. Hence the spatial information is delivered to real world users such as mobile users, therefore ensuring spatial integrity in OSDB becomes critical. To overcome this problem, Voronoi Neighbor Authentication (VN - Auth) technique is used, which utilizes the Voronoi diagram to prove the integrity of query result for the kNN query. Spatial query processing in spatial database attempts to extract specific geometric relations among spatial objects. The Service Provider verifies correctness and completeness of user query through which neighborhood information of Voronoi diagram. However the privacy of user location is not achieved in this paper. To avoid this drawback, it is proposed to apply Privacy aware LBS technique under the Voronoi Neighbor concept.
