The New Casper: Query Processing for Location Services without Compromising Privacy

Summary: Casper offers private location-based services by converting exact positions into cloaked regions via a location anonymizer. A privacy-aware query processor in LBS DB operates on cloaked regions to deliver quality results with data and query anonymity. (summarized by gpt-5-nano on Feb 09 2026)
