Abstract

Geo-security service, which refers to the authorization of persons or facilities based on their distinctive location information, is an application of the fields of position, navigation and time (PNT). Location features from radio navigation signals are mapped into a precise verification tag or geotag to block or allow certain action or access. A device that integrates a location sensor and geotag generation algorithm is tamper-resistant, that is, one cannot spoof the device to bypass the location validation. This paper develops a theoretical framework of the geotag-based positioning and security systems, and evaluates the system performance analytically and experimentally by using Loran signals as a case study.
