Privacy-preserving trajectory stream publishing
Data & Knowledge Engineering, 2014Recent advancement in mobile computing and sensory technology has facilitated the possibility of continuously updating, monitoring, and detecting the latest location and status of moving individuals. Spatio-temporal data generated and collected on the fly are described as trajectory streams.

SST: Privacy Preserving for Semantic Trajectories
2015 16th IEEE International Conference on Mobile Data Management, 2015To preserve privacy in trajectory data, most existing approaches adapt cloaking techniques to protect individual location points or clustering and perturbation techniques to protect entire trajectories. To confirm to the k-anonymity model, they first group locations/trajectories and then modify location points to ensure a cluster of k location points ...

Trajectory Privacy Protection on Spatial Streaming Data with Differential Privacy
2018 IEEE Global Communications Conference (GLOBECOM), 2018Continuously sharing user's trajectory data which contain one's location information makes the crowd sensing of the traffic dynamics and mobility trends feasible. This kind of spatial streaming data is beneficial for intelligent transportation but at the risk of disclosing personal privacy, even if it is published in statistical form such as “the ...

DP-TrajGAN: A privacy-aware trajectory generation model with differential privacy
Future Generation Computer Systems, 2023Open Data Processing Services (ODPS) offers vast storage capacity and excellent efficiency, which collects and stores a lot of data. As an essential component of ODPS, location-based services (LBS) are widely used in many aspects. However, LBS generates tens of thousands trajectories, which have a significant likelihood of revealing personal ...

Protecting Privacy in Trajectories with a User-Centric Approach
ACM Transactions on Knowledge Discovery from Data, 2018The increased use of location-aware devices, such as smartphones, generates a large amount of trajectory data. These data can be useful in several domains, like marketing, path modeling, localization of an epidemic focus, and so on. Nevertheless, since trajectory information contains personal mobility data, improper use or publication of trajectory ...

An Enhanced Method of Trajectory Privacy Preservation Through Trajectory Reconstruction
2017Trajectory data of mobile users contain plenty of sensitive spatial and temporal information, and can support many applications through data analysing and mining. However, re-identification attack and inference attack on such data may cause serious personal privacy leakage.

Privacy and Security in Spatiotemporal Data and Trajectories
2008The European directive 2002/58/EC requires providers of public communication networks and electronic communication services to adopt techniques to ensure data security and privacy. This directive states, among others, that the provider of a publicly available electronic communication service must take appropriate technical and organizational measures ...
