Abstract
Since location-based service (LBS) was proposed, the location privacy protection schemes are wildly researched. However, because of many reasons such as making unrealistic assumption, incurring high server load or degrading quality of service, there are few schemes can be further practically implemented. A newly proposed location privacy protection scheme, named SpaceTwist [1], is novel as well as effective. Based on its concept, we propose an efficient way for location-based service privacy protection scheme in this thesis. The major differences are (i) maximum restriction termination condition in client-side algorithm and (ii) S-strategy for setting proper query distance and cell extent. We run our simulation in real POI (Point of Interest) datasets derived from Google local search API (Application Programming Interface) and the results is desirable.
