Protecting location privacy [PDF]
Proceedings of the 2012 ACM conference on Computer and communications security, 2012 The mainstream approach to protecting the location-privacy of mobile users in location-based services (LBSs) is to alter the users' actual locations in order to reduce the location information exposed to the service provider. The location obfuscation algorithm behind an effective location-privacy preserving mechanism (LPPM) must consider three ...

DPLQ: Location‐based service privacy protection scheme based on differential privacy
IET Information Security, 2021 The existing privacy protection schemes for Location‐Based Service (LBS) only protect users' location privacy or query privacy, which can not adopt both of the privacy protections simultaneously in the LBS system. Moreover, these schemes cannot take into
