ABSTRACT
A location corroboration of a person is a proof, in the form of a digital record, indicating that this person was at a particular place at a given time. That is, given a user u, a location l and a time t, a location corroboration is a certified evidence that u was at location l at time t. Such corroborations can be used in legal procedures, help solving personal disputes or enable services that rely on knowing with certainty the location of a user at a given time. A corroboration without traces means that the user location is not stored in any public server or in any other public entity, to protect the user privacy. In this paper we present the problem of producing a location corroboration without traces, using a mobile device, and we discuss possible solutions to it.

Toward Privacy Preserving and Collusion Resistance in a Location Proof Updating System
Today's location-sensitive service relies on user's mobile device to determine the current location. This allows malicious users to access a restricted resource or provide bogus alibis by cheating on their locations. To address this issue, we propose A ...
Preserving location privacy without exact locations in mobile services
Privacy preservation has recently received considerable attention in location-based services (LBSs). A large number of location cloaking algorithms have been proposed for protecting the location privacy of mobile users. However, most existing cloaking ...
Protecting location privacy using location semantics
KDD '11: Proceedings of the 17th ACM SIGKDD international conference on Knowledge discovery and data miningAs the use of mobile devices increases, a location-based service (LBS) becomes increasingly popular because it provides more convenient context-aware services. However, LBS introduces problematic issues for location privacy due to the nature of the ...
