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.
Claims14
At least one non-transitory machine-readable medium comprising instructions, that, when executed cause a programmable device to:
- obtain geo-location data corresponding to a location of the programmable device;
- send the geo-location data and a first cryptographic signature to a geo-location data provider station, the first cryptographic signature including a chain of previous cryptographic signatures, respective ones of the chain of previous cryptographic signatures corresponding to previous locations of the programmable device;
- receive from the geo-location data provider station a second cryptographic signature, the second cryptographic signature including a cryptographic signature of (a) the geo-location data obtained from the programmable device, (b) geo-location data corresponding to a current location of the geo-location provider station and (c) the first cryptographic signature;
- and
- store the second cryptographic signature by adding the second cryptographic signature data to the chain of previous cryptographic signatures, the geo-location data including timestamped two-dimensional or three-dimensional coordinates in a geo-location coordinate system.

- and
- transmit the second cryptographic signature to the mobile device, the geo-location data obtained from the mobile device and the geo-location data corresponding to the current location of the geo-location data provider station including at least one of timestamped two-dimensional coordinates or three-dimensional coordinates in a geo-location coordinate system.
