User Location Anonymization Method for Wide Distribution of Dummies
2013Advances in GPS (global positioning system) technologies have led to a variety of services utilizing the user’s location becoming available. Since location information may reveal private information, preserving location privacy has become a significant issue. To preserve this privacy, we have proposed a user location anonymization method that generates

An anonymous communication technique using dummies for location-based services
ICPS '05. Proceedings. International Conference on Pervasive Services, 2005., 2005Recently, highly accurate positioning devices enable us to provide various types of location-based services. On the other hand, because such position data include deeply personal information, the protection of location privacy is one of the most significant problems in location-based services.

A Dummy Location Generation Model for Location Privacy in Vehicular Ad hoc Networks
2020The vehicular ad hoc networks are designed to tackle the problems that occur due to the proliferation of vehicles in our society. However, most of its applications require the access to location of vehicles participating in the network and may lead to life-threatening situations.

Privacy-area aware dummy generation algorithms for Location-Based Services
2014 IEEE International Conference on Communications (ICC), 2014Location-Based Services (LBSs) have been one of the most popular activities in our daily life. Users can send queries to the LBS server easily to learn their surroundings. However, these location-related queries may result in serious privacy concerns since the un-trusted LBS server has all the information about users and may track them in various ways.

Dummy-Based Location Anonymization for Controlling Observable User Preferences
2019 IEEE Global Communications Conference (GLOBECOM), 2019In this paper, we propose a location anonymization method which can control the degree of preserving user preferences on visiting locations, where the user's preferences are defined as a series of categories of the visiting locations. Based on the user's requirement, this method mixes dummies that move by following the user's preferences and that do ...

Combining Spatial Cloaking and Dummy Generation for Location Privacy Preserving
2012Location privacy preserving is attracting more and more attentions with the wide use of accurate positioning devices. Two kinds of methods based on k-anonymity have been proposed for location privacy preserving. One is spatial cloaking and the other is dummy generation.

Location privacy from dummy devices in database-coordinated spectrum sharing
2017 IEEE International Symposium on Dynamic Spectrum Access Networks (DySPAN), 2017One way to make more spectrum available is through white space sharing, where secondary spectrum users are allowed to transmit from any location except inside exclusion zones (EZs) that are drawn around primary spectrum users (PUs). However, EZ boundaries reveal the locations of PUs, and for some devices, location privacy is extremely important ...

2010 International Conference on Availability, Reliability and Security, 2010
We propose a binomial-mix-based location anonymizer system with global dummy generation to protect user location privacy in location-based services in the face of attacks from a global active adversary and even with untrusted location-based service providers.

Dummies and Nearest Neighbor Based Location Privacy Protection
Journal of Information and Computational Science, 2013Location-based services require users to supply their location information. However, a user’s location can be tracked without her consent or knowledge. Once the trajectory of a user is identified, his locations will be exposed. Thus, it is critical to protect the movement trajectories of mobile users in order to preserve user location privacy.

Dummy-Based Trajectory Privacy Protection Against Exposure Location Attacks
2019With the development of positioning technology and location-aware devices, moving objects’ location and trajectory information have been collected and published, resulting in serious personal privacy leakage. Existing dummy trajectory privacy preserving method does not consider user’s exposure locations, which causes the adversary can easily exclude ...
