The New Casper: A Privacy-Aware Location-Based Database Server

This demo presents Casper; a framework in which users entertain anonymous location-based services. Casper consists of two main components; the location anonymizer that blurs the users´ exact location into cloaked spatial regions and the privacy-aware query processor that is responsible on providing location-based services based on the cloaked spatial regions. While the location anonymizer is implemented as a stand alone application, the privacy-aware query processor is embedded into PLACE; a research prototype for location-based database servers.
