Trajectory Privacy Protection Mechanism based on Social Attributes
CoRR, 2022 The current trajectory privacy protection technology only considers the temporal and spatial attributes of trajectory data, but ignores the social attributes. However, there is an intrinsic relationship between social attributes and human activity trajectories, which brings new challenges to trajectory privacy protection, making existing trajectory ...

Interchange-Based Privacy Protection for Publishing Trajectories [PDF]
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.

CLM:differential privacy protection method for trajectory publishing
Tongxin xuebao, 2017 In order to solve the problem existing in differential privacy preserving publishing methods that the independent noise was easy to be filtered out,a differential privacy publishing method for trajectory data (CLM),was proposed.A correlated Laplace ...

A Semantic Behavioral Sequence-Based Approach to Trajectory Privacy Protection
SymmetryTrajectory data contain numerous sensitive attributes. Unauthorized disclosure of precise user trajectory information generates persistent privacy and security concerns that significantly impact daily life. Most existing trajectory privacy protection schemes focus on geographic trajectories while neglecting the critical importance of semantic ...

Trajectory mining, representation and privacy protection [PDF]
Proceedings of the 2nd ACM SIGSPATIAL PhD Workshop, 2015 The maturing of mobile devices and systems provides an unprecedented opportunity to collect a large amount of real world human motion data at all scales. The rich knowledge contained in these data sets is valuable. In this analysis, we first study information dissemination through the physical contacts learnt from the data sets.
