Abstract
A geo-location provider station signs geo-location data and a previous signature provided by a mobile device, returning a new signature to the mobile device. The mobile device uses the new signature when requesting a signature from another geo-location provider station. The mobile device stores the geo-location data and the signatures provided by geo-location provider stations. The stored geo-location data may be verified upon request by using the stored signature data.
