INTACT: a spatial query integrity assurance framework for location-based services

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 locaTionbased services) framework on the iPhone and the .NET Framework that protects data privacy using space encryption and ensures query integrity via audit queries.
