A survey of computational location privacy
Personal and Ubiquitous Computing, 2008This is a literature survey of computational location privacy, meaning computation-based privacy mechanisms that treat location data as geometric information. This definition includes privacy-preserving algorithms like anonymity and obfuscation as well as privacy-breaking algorithms that exploit the geometric nature of the data.

We study the problem of releasing private data where the severity of the privacy concerns depends on the data itself. As a working example, we focus on the problem where a user shares an approximation of her private GPS location with a location-based service under privacy constraints that depend on the population density at user's current location ...

Location Obfuscation for Location Data Privacy
2015 IEEE World Congress on Services, 2015Advances in wireless internet, sensor technologies, mobile technologies, and global positioning technologies have renewed interest in location based services (LBSs) among mobile users. LBSs on smartphones allow consumers to locate nearby products and services, in exchange of their location information.

CHI '13 Extended Abstracts on Human Factors in Computing Systems, 2013
The privacy problems associated with disclosing location information have repeatedly been the subject of research during the past decade. Yet, only the increasing adoption of smartphones today unveils real world implications, since a large number of users currently use location-based services and GPS-enabled devices for a multitude of purposes ...

Middleware for location privacy
Proceedings of the 2012 ACM Research in Applied Computation Symposium, 2012As context-aware mobile applications become increasingly common, privacy issues hit headlines again. Users are faced with a trade-off. On one hand, releasing information about their location allows them to take advantage of new location-based services. On the other hand, releasing such information raises privacy issues about the potential inadequate or

We discuss ways to enhance the location privacy of Bluetooth. The principal weakness of Bluetooth with respect to location privacy lies in its disclosure of a device’s permanent identifier, which makes location tracking easy. Bluetooth’s permanent identifier is often disclosed and it is also tightly integrated into lower layers of the Bluetooth stack ...

In this chapter, the author raises a number of issues surrounding the ever-growing capabilities of geoinformatics. Location privacy can be defined as the claim of individuals to determine for themselves when, how, and to what extent information about their geographic location is communicated to others.

Privacy-aware Location Privacy Preference Recommendations
Proceedings of the 11th International Conference on Mobile and Ubiquitous Systems: Computing, Networking and Services, 2014Location-Based Services have become increasingly popular due to the prevalence of smart devices and location-sharing applications such as Facebook and Foursquare. The protection of people's sensitive location data in such applications is an important requirement.

Location Privacy of Users in Location-based Services
2006 Third Annual International Conference on Mobile and Ubiquitous Systems: Networking & Services, 2006In this paper, we introduce Location Traceability as an indicator for evaluating time-series location privacy for users on location-based services (LBS). The location trace-ability of a user is calculated with a formalized tree structure that represents all possible paths of a moving user. Through the results of the simulation experiments, we validated

Location privacy in pervasive computing
IEEE Pervasive Computing, 2003As location-aware applications begin to track our movements in the name of convenience, how can we protect our privacy? This article introduces the mix zone-a new construction inspired by anonymous communication techniques-together with metrics for assessing user anonymity. It is based on frequently changing pseudonyms.
