Abstract:

In outsourced spatial databases, the LBS provide query services to the clients on behalf of the data owner. However, the LBS provider is not always trustworthy and it may send incomplete or incorrect query results to the clients. Therefore ensuring spatial query integrity is critical. Efficient kNN query verification techniques which utilize the influence zone to check the integrity of query results. kNN query continuously reports the k results (restaurants) nearest to a moving query point. In order to minimize the communication cost between the service provider and the mobile client, a framework for authenticating both the query results and the safe regions of moving kNN queries is proposed. The new method can perform moving kNN query authentication with small communication costs.
