DGS-HSA: A Dummy Generation Scheme Adopting Hierarchical Structure of the Address

open access: yesApplied 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

open access: yesIET 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

Semantic and Trade-Off Aware Location Privacy Protection in Road Networks Via Improved Multi-Objective Particle Swarm Optimization

open access: yesIEEE Access, 2021
Location privacy protection is an essential but challenging topic in the field of network security. Although the existing research methods, such as ${k}$ -anonymity, mix zone, and differential privacy, show significant success, they usually neglect the ...

A Location Privacy Aware Friend Locator [PDF]

open access: yes, 2009
A location-based service called friend-locator notifies a user if the user is geographically close to any of the user’s friends. Services of this kind are getting increasingly popular due to the penetration of GPS in mobile phones, but existing commercial friend-locator services require users to trade their location privacy for quality of service ...

Location Privacy in Conservation

open access: yesCoRR, 2019
The growing public nature of academic journals along with current best practices of sharing primary data for scientific research are profoundly valuable for the understanding of a species and their conservation efforts. On the other hand, public spatial data on endangered species may be easily abused by wildlife criminals. In this paper, we discuss how

Continuous location privacy protection mechanism based on differential privacy

open access: yesTongxin xuebao, 2021
Aiming at the problem of users’ location privacy leakage caused by continuously using LBS, a road privacy level (RPL) algorithm was proposed based on road topological network, which divided the privacy level of the road sections around the sensitive ...
