Eclipse: Preserving Differential Location Privacy Against Long-Term Observation Attacks
IEEE Transactions on Mobile Computing(2022)
摘要
Mechanisms built upon geo-indistinguishability render location privacy, where a user can submit obfuscated locations to Location-Based Service providers but still be able to correctly utilize services. However, these mechanisms are vulnerable under inference attacks. Particularly, with background knowledge of a user’s obfuscated locations, an attacker can infer actual locations by carrying out lon...
