A Survey and Experimental Study on Privacy-Preserving Trajectory Data Publishing [PDF]
IEEE Transactions on Knowledge and Data Engineering, 2021 <div>Trajectory data has become ubiquitous nowadays, which can benefit various real-world applications such as traffic management and location-based services. However, trajectories may disclose highly sensitive information of an individual including mobility patterns, personal profiles and gazetteers, social relationships, etc, making it ...

Differential-Privacy Preserving Trajectory Data Publishing for Road Networks
, 2023 In the sharing of user trajectory data of road networks, privacy leakage emerges to be a major concern because attackers may make aggressive reasoning and analysis based on the published trajectory data with certain background knowledge to obtain the ...

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 ...

Trajectory anonymity in publishing personal mobility data
ACM SIGKDD Explorations Newsletter, 2011 Recent years have witnessed pervasive use of location-aware devices such as GSM mobile phones, GPS-enabled PDAs, location sensors, and active RFID tags. The use of these devices generates a huge collection of spatio-temporal data, variously called moving object data, trajectory data, or moblity data.

A Clustering-Anonymity Approach for Trajectory Data Publishing Considering both Distance and Direction [PDF]
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.

Sensitive attribute privacy preservation of trajectory data publishing based on l-diversity. [PDF]
Distrib Parallel Databases, 2021 The widely application of positioning technology has made collecting the movement of people feasible for knowledge-based decision. Data in its original form often contain sensitive attributes and publishing such data will leak individuals' privacy. Especially, a privacy threat occurs when an attacker can link a record to a specific individual based on ...
