Abstract

It is cost-effective for data owners to publicize their spatial databases via database outsourcing; however, data privacy and query integrity are major challenges. In this demonstration, we implemented the INTACT (spatial query INTegrity AssuranCe framework for locaTion-based services) framework on the iPhone and the .NET Framework that protects data privacy using space encryption and ensures query integrity via audit queries.
