Abstract
Recent advances in mobile device, wireless networking, and positional technologies have helped location-aware applications become pervasive. However, location trajectory privacy concerns hinder the adoptability of such applications. In this article, we survey existing trajectory privacy work in the context of wireless sensor networks, location-based services, and geosocial networks. In each context, we categorize and summarize the main techniques according to their own feathers. Furthermore, we discuss future trajectory privacy research challenges and directions.

Recommendations
Protection of sensitive trajectory datasets through spatial and temporal exchange
SSDBM '14: Proceedings of the 26th International Conference on Scientific and Statistical Database ManagementPrivacy concerns place a great impediment to publishing and/or exchanging trajectory data across companies and institutions. This has urged researchers to address privacy issues prior to trajectory data release. Currently, privacy preserving solutions ...
PGLP: Customizable and Rigorous Location Privacy Through Policy Graph
Computer Security – ESORICS 2020AbstractLocation privacy has been extensively studied in the literature. However, existing location privacy models are either not rigorous or not customizable, which limits the trade-off between privacy and utility in many real-world applications. To ...
Trajectory Privacy Preserving for LBS in P2P Environment
ICBDC '18: Proceedings of the 3rd International Conference on Big Data and ComputingThis paper presents a trajectory similarity measurement method based on user's local anonymous area. This method can protect the location privacy among users between each other in an anonymous group. Based on the trajectory similarity and real user's ...
