Interchange-Based Privacy Protection for Publishing Trajectories

IEEE Access, 2019
Information extracted from trajectory data is very useful in many practical application scenarios. Before trajectories for data mining are published, they need to be processed to protect the privacy of the trajectories' bodies.

A Trajectory Privacy Protection Scheme Based on the Replacement of Stay Points

Applied Sciences
Location-based services generate a large amount of location and trajectory data, which contain rich spatiotemporal and semantic information. Publishing these data without proper protection can seriously threaten users’ trajectory privacy.

Protecting privacy of semantic trajectory

, 2021
The growing ubiquity of GPS-enabled devices in everyday life has made large-scale collection of trajectories feasible, providing ever-growing opportunities for human movement analysis. However, publishing this vulnerable data is accompanied by increasing concerns about individuals’ geoprivacy.

Towards Privacy-Preserving Semantic Mobility Analysis [PDF]

By analyzing data reflecting human mobility, one can derive patterns and knowledge that are tightly linked to the underlying geography and therefore cannot be applied to another territory or even compared with patterns obtained for another territory ...

Dummy trajectory privacy protection scheme for trajectory publishing based on the spatiotemporal correlation

Tongxin xuebao, 2016
The spatiotemporal correlation was analyzed between neighboring locations and the trajectories similarity from the movement direction, the reachable time between neighboring locations and the movement distance, and a dummy trajectory privacy protection ...

Efficient scheme for user's trajectory privacy

Tongxin xuebao, 2015
As one of the most important information in location-based services (LBS),the trajectory privacy for smart devices users has gained increasingly popularity over recent years.To address this problem,(k−1) dummy trajectories to achieve trajectory k-anonymity with comprehensively considering side information were generated,user's mobility pattern and the ...
