Themes and Goals

Although data security and privacy issues have been extensively investigated in several domains, the current available techniques are not readily applicable for privacy protection in location-based applications. These applications include, but are not limited to, Location-Based Services (LBS). LBS requests are typically invoked through mobile devices that can provide information including the location of the user, her direction, and speed. Other location-based applications use similar data, possibly stored in a moving object database, to solve different kinds of optimization problems, to perform statistical analysis of specific phenomena, as well as to predict potentially critical situations. While location data can be very effective for service personalization and can enable new kind of services, it poses serious threats to the privacy of users. LBS in travel, logistics, health care, and other industries already exist and are poised to proliferate. Examples of these services are the identification of resources close to the user (e.g., the closest pharmacy), or the identification of the optimal route to reach a destination from the user's position considering traffic conditions and possibly other constraints.

One of the critical issues for a wide-spread deployment of these applications is how to conciliate the effectiveness and quality of these services with privacy concerns. They bring unique challenges mostly due to the richness of location and time information that is necessarily connected to location based applications. The research in this field involves aspects of spatio-temporal reasoning, query processing, system security, statistical inference, and more importantly anonymization techniques. Several research groups have been working in the last years to identify privacy attacks and defense techniques in this domain.

Topics

• Formal models of attacks and defenses in LBA
• Anonymization/Pseudonymization in LBA
• Sensitive data obfuscation in LBA
• Authorization and Access Control involving spatio-temporal data
• Publication of micro-data acquired through LBA
• Privacy preserving data mining on geographically referenced data
• Statistical approaches to privacy preservation in LBA
• Trust Management in LBA
• Applied Cryptography for LBA

Format of the workshop and proceedings

It will be a one day workshop held in conjunction with the 13th European Symposium on Research in Computer Security.
The workshop will be opened by an invited talk, and will continue with sessions of 2-4 presentations, each one followed by a plenary panel/discussion including questions to the speakers. The session chair will moderate the panel.

Workshop proceedings are published as CEUR Workshop Proceedings (CEUR-WS.org is a recognized ISSN publication series) and are publicly accessible online (CEUR-WS.org/Vol-397).

Selected contributions will later be invited for inclusion in an edited book on the workshop topics published by Springer in the LNCS series.
