Quantifying Location Privacy [PDF]
2011 IEEE Symposium on Security and Privacy, 2011 It is a well-known fact that the progress of personal communication devices leads to serious concerns about privacy in general, and location privacy in particular. As a response to these issues, a number of Location-Privacy Protection Mechanisms (LPPMs) have been proposed during the last decade.

Collaborative Location Privacy [PDF]
2011 IEEE Eighth International Conference on Mobile Ad-Hoc and Sensor Systems, 2011 Location-aware smart phones support various location-based services (LBSs): users query the LBS server and learn on the fly about their surroundings. However, such queries give away private information, enabling the LBS to identify and track users. We address this problem by proposing the first, to the best of our knowledge, user-collaborative privacy ...

DGS-HSA: A Dummy Generation Scheme Adopting Hierarchical Structure of the Address
Applied Sciences, 2020 With the increasing convenience of location-based services (LBSs), there have been growing concerns about the risk of privacy leakage. We show that existing techniques fail to defend against a statistical attack meant to infer the user’s location privacy

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
