Privacy Risks in Publishing Mobile Device Trajectories
IEEE Wireless Communications Letters, 2014Growing availability of mobile devices capable of sensing and transmitting geospatial information has led to a wide range of location based services (LBSs). Sharing location data with others is an intrinsic feature of LBSs. However, publishing location may raise serious privacy concerns due to its close connection with users' sensitive information ...

STDP: Secure Privacy-Preserving Trajectory Data Publishing
2018 IEEE International Conference on Internet of Things (iThings) and IEEE Green Computing and Communications (GreenCom) and IEEE Cyber, Physical and Social Computing (CPSCom) and IEEE Smart Data (SmartData), 2018As the smart devices and cloud services are rapidly expanding, a large amount of location information can easily be gathered. However, there is a conflict between collecting location information and protecting personal information since obtaining and utilizing the information may be restricted due to privacy concerns. In fact, various methods which use

Trajectory anonymity in publishing personal mobility data
ACM SIGKDD Explorations Newsletter, 2011Recent 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.

Mincer Algorithm: Privacy Protection for Publishing Trajectories Dynamically
2020 12th International Conference on Intelligent Human-Machine Systems and Cybernetics (IHMSC), 2020Some applications require real-time analysis of trajectory data. But the direct release of the original trajectory to a third party for analysis will threaten the privacy of the trajectory subject. So the protection of trajectory privacy published dynamically is important.

SLAT: Sub-Trajectory Linkage Attack Tolerance Framework for Privacy-Preserving Trajectory Publishing
2018 International Conference on Networking and Network Applications (NaNA), 2018The pervasiveness of location-aware devices offers terrific opportunities for analyzing and mining human mobility. Yet, sharing of trajectory data poses personal privacy issues. Consider a dataset of trajectories, containing detailed movement information about individuals, published with sensitive attributes such as disease, income, etc.

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 ...

Suppression techniques for privacy-preserving trajectory data publishing
Knowledge-Based Systems, 2020Abstract In this paper, we study the problem of protecting privacy in trajectory datasets from adversaries who can exploit their partial knowledge to infer unknown locations. To efficiently solve this problem, we propose a tree-based indexing structure to store all trajectory data and develop pruning strategies.

Real-Time Trajectory Data Publishing Method with Differential Privacy
2018 14th International Conference on Mobile Ad-Hoc and Sensor Networks (MSN), 2018With the increasing popularity of location technologies and location-based service applications, a large number of user's trajectory data have been collected. Publishing the real-time statistics data of trajectory streams can be useful in many fields such as intelligent transportation system, urban road planning and road congestion detection.

Optimal Space Trajectories—A Review of Published Work
The Aeronautical Journal, 1968The problem of transferring a space vehicle between two points in a given gravitational field such that the minimum amount of fuel is used has been called the fundamental navigational problem of astronautics. In such a problem it may be required to find the optimum thrust magnitude and thrust direction which yields a minimum fuel trajectory ...

Publishing Sensitive Trajectory Data Under Enhanced l-Diversity Model
2019 20th IEEE International Conference on Mobile Data Management (MDM), 2019With the proliferation of location-aware devices, trajectory data have been widely collected, published, and analyzed in real-life applications. However, published trajectory data often contain sensitive attributes, so an attacker who can identify an individual from such data through record linkage, attribute linkage, or similarity attacks can gain ...
