A Game-Theoretic Framework to Preserve Location Information Privacy in Location-based Service Applications

A taxonomy of approaches to preserve location privacy in location-based services

The ubiquity of smartphones and other location-aware hand-held devices has resulted in a dramatic increase in popularity of location-based services (LBS) tailored to users’ locations. The comfort of LBS comes with a privacy cost. Various distressing privacy violations caused by sharing sensitive location information with potentially malicious services have highlighted the importance of location...

Location Positioning and Privacy Preservation Methods in Location-based Service

Location-based services (LBS) become more feature-rich and versatile due to the explosion of mobile devices and the advances of positioning technologies. However, revealing personal private locations to potentially un-trusted LBS server and others may raise serious privacy concerns if these locations are not protected adequately. In this paper, we present a survey of existing methods dealing wi...

Survey of Location privacy in Location Based Service Proposal

Blind evaluation of location based queries using space transformation to preserve location privacy

In this paper we propose a fundamental approach to perform the class of Range and Nearest Neighbor (NN) queries, the core class of spatial queries used in location-based services, without revealing any location information about the query in order to preserve users’ private location information. The idea behind our approach is to utilize the power of one-way transformations to map the space of ...

Towards an information theoretic framework for location-based data linkage

A long-standing challenge for data management is the ability to correctly relate information corresponding to the same entity distributed across databases. Traditional research into record linkage has concentrated on string comparator metrics for records with common, or relatable, attributes. However, spatially distributed data are often devoid of such crucial information for database schema in...
