Nearest Neighbor Search with Strong Location Privacy
Summary: Defines strong location privacy for kNN queries, making a single query indistinguishable from any location in the data space. Proposes secure hardware-aided PIR; evolves from a baseline to AHG, addressing drawbacks and boosting privacy-preserving kNN performance. (summarized by gpt-5-nano on Feb 09 2026)
