A personalized trajectory privacy protection method

Computers & Security, 2021
Abstract 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

Protecting Privacy in Trajectories with a User-Centric Approach

ACM Transactions on Knowledge Discovery from Data, 2018
The 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 ...

Trajectory Privacy Protection on Spatial Streaming Data with Differential Privacy

2018 IEEE Global Communications Conference (GLOBECOM), 2018
Continuously 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 ...

Protecting trajectory privacy: A user-centric analysis

Journal of Network and Computer Applications, 2017
Abstract The existing evaluation methods for location privacy protection mechanism (LPPM) focus mainly on location privacy at the time of issuing a location-based query, and rarely consider trajectory privacy from where multiple successive queries are issued.

A Novel Time-Obfuscated Algorithm for Trajectory Privacy Protection

IEEE Transactions on Services Computing, 2014
Location-based services (LBS) which bring so much convenience to our daily life have been intensively studied over the years. Generally, an LBS query processing can be categorized into snapshot and continuous queries which access user location information and return search results to the users.

Method of trajectory privacy protection based on restraining trajectory in LBS

International Journal of Information and Communication Technology, 2018
With the development of mobile positioning technology, location-based services are becoming more and more widely used in life, but it has produced the security problem of the user's privacy leakage. In this paper, the problem of user trajectory privacy protection in location-based services is introduced, and a method of trajectory privacy protection ...

Trajectory Privacy Protection Scheme for Different Travel Modes

2021
The problem of trajectory privacy is getting more attention in recent years. It is unreasonable to adopt the same privacy protection scheme in diversified travel modes, since the trajectories have different constraints under different travel modes.

Protecting Privacy-Sensitive Locations in Trajectories with Correlated Positions

2019 IEEE Global Communications Conference (GLOBECOM), 2019
The location privacy issue has become a critical research topic recently. The existing solutions do not solve one typical problem in practice: people may only want to protect certain privacy-sensitive locations among a group of temporal and spatial correlated points in a trajectory.

User Relationship Privacy Protection on Trajectory Data

2019
Various mobile devices facilitate the users’ life, but the issues are brought into privacy focus by the individuals. This paper aims at the protection of intimate relationships among users. We consider the intimacy of user relationships based on similar sub-trajectories between the users. Then, we propose a \(k_{mn}\)-anonymity protection model.
