In-Network Trajectory Privacy Preservation
ACM Computing Surveys, 2015Recent 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 ...

A personalized trajectory privacy protection method
Computers & Security, 2021Abstract Trajectory data of sports or activities are usually collected and shared into social apps like Wechat moments, Sina weibo in public to provide health services and recommendation, while a large number of friends with weak ties in social circle will cause privacy leakage of users’ locations and life habits. To solve the problem, a personalized

Publishing trajectories with differential privacy guarantees
Proceedings of the 25th International Conference on Scientific and Statistical Database Management, 2013The pervasiveness of location-acquisition technologies has made it possible to collect the movement data of individuals or vehicles. However, it has to be carefully managed to ensure that there is no privacy breach. In this paper, we investigate the problem of publishing trajectory data under the differential privacy model.

Privacy Preserving Trajectory Data Publishing with Personalized Differential Privacy
2020 IEEE Intl Conf on Parallel & Distributed Processing with Applications, Big Data & Cloud Computing, Sustainable Computing & Communications, Social Computing & Networking (ISPA/BDCloud/SocialCom/SustainCom), 2020With the development of location-based applications, more and more trajectory data are collected and applied. Trajectory data often contains user's sensitive information, and direct release may pose a threat to users' privacy. Differential privacy, as a privacy preserving method with solid mathematical foundation, has been widely used in trajectory ...

Enhancing the Trajectory Privacy with Laplace Mechanism
2015 IEEE Trustcom/BigDataSE/ISPA, 2015Mobile-aware service systems are dramatically increasing the amount of personal data released to service providers as well as to third parties. Data may reveal individuals' physical conditions, habits, and sensitive information. It raises serious privacy concerns. Current approaches to mitigate the privacy concerns rely on the randomization.

Privacy of Spatial Trajectories
2011The ubiquity of mobile devices with global positioning functionality (e.g., GPS and Assisted GPS) and Internet connectivity (e.g., 3G and Wi-Fi) has resulted in widespread development of location-based services (LBS). Typical examples of LBS include local business search, e-marketing, social networking, and automotive traffic monitoring.
