An efficient method for privacy-preserving trajectory data publishing based on data partitioning

The Journal of Supercomputing, 2019
Since Osman Abul et al. first proposed the k-anonymity-based privacy protection for trajectory data, researchers have proposed a variety of trajectory privacy-preserving methods. These methods mainly adopt a static anonymity algorithm, which only focusing on the trajectories in a specific time span, directly anonymizes data and publishes them without ...

A Clustering-Anonymity Approach for Trajectory Data Publishing Considering both Distance and Direction

Journal of computing and information technology, 2022
Trajectory data contains rich spatio-temporal information of moving objects. Directly publishing it for mining and analysis will result in severe privacy disclosure problems. Most existing clustering-anonymity methods cluster trajectories according to either distance- or direction-based similarities, leading to a high information loss.

Trajectory Data Publishing Scheme Based on Transformer Decoder and Differential Privacy

ISPRS International Journal of Geo-Information
The proliferation of Location-Based Services (LBSs) has generated vast trajectory datasets that offer immense analytical value but pose critical privacy risks. Achieving an optimal balance between data utility and privacy preservation remains a challenge,

Impact of prior knowledge on privacy leakage in trajectory data publishing

Engineering Science and Technology, an International Journal, 2020
Abstract The rapid growth in the usage of location-based services has resulted in extensive research on users’ trajectory data publishing. But, a key concern here is a potential breach of user privacy through various linkage attacks by an efficient adversary.

Privacy in trajectory micro-data publishing : a survey [PDF]

Trans. Data Priv., 2019
We survey the literature on the privacy of trajectory micro-data, i.e., spatiotemporal information about the mobility of individuals, whose collection is becoming increasingly simple and frequent thanks to emerging information and communication technologies.

Spatiotemporal Mobility Based Trajectory Privacy-Preserving Algorithm in Location-Based Services

Sensors, 2021
Recent years have seen the wide application of Location-Based Services (LBSs) in our daily life. Although users can enjoy many conveniences from the LBSs, they may lose their trajectory privacy when their location data are collected.
