CERTILOC: Implementation of a Spatial-Temporal Certification Service Compatible with Several Localization Technologies

Recently researchers are being encouraged to address security and privacy requirements for location information. This work contributes to this area by presenting CERTILOC, a prototype of a spatial-temporal certification service that is interoperable with representative localization technologies (GSM Cell-ID and GPS). Our work is completed with a broad threat analysis on spatial-temporal certification services and an exposition of legal considerations that can be made if used in work scenarios.
