1. A method for location-based authentication using medium earth orbit (MEO) and low earth orbit (LEO) satellites, the method comprising:
- receiving at a server a client MEO signal signature comprising samples over an MEO signature time period of at least one client received MEO satellite signal received at a client device from at least one MEO satellite footprint of at least one MEO satellite;
constructing a server MEO signal signature comprising samples over the MEO signature time period of at least one server received MEO satellite signal received from the at least one MEO satellite;
comparing the client MEO signal signature and the server MEO signal signature to provide an MEO comparison result;
receiving at the server a client LEO signal signature comprising samples over an LEO signature time period of at least one client received LEO satellite signal received at the client device from at least one LEO satellite footprint of at least one LEO satellite;
constructing a server LEO signal signature comprising samples over the LEO signature time period of at least one server LEO satellite signal of the at least one LEO satellite;
comparing the client LEO signal signature and the server LEO signal signature to provide an LEO comparison result; and
authenticating that the client device is at an asserted location based on the MEO comparison result and the LEO comparison result to authenticate the asserted location of the client device.

Abstract
A system and methods for location-based authentication using medium earth orbit (MEO) and low earth orbit (LEO) satellites are presented. Location of a client device is authenticated based on at least one client received MEO satellite signal received from at least one MEO satellite at the client device and at least one client received LEO satellite signal received from at least one LEO satellite at the client device.

17. A non-transitory computer readable storage medium comprising computer-executable instructions for client location-based authentication, the computer-executable instructions comprising:
-
receiving at least one client received MEO satellite signal at a client device from at least one MEO satellite footprint of at least one MEO satellite; receiving at least one client received LEO satellite signal at the client device from at least one LEO satellite footprint of at least one LEO satellite; constructing a client MEO signal signature comprising samples over an MEO signature time period of the at least one client received MEO satellite signal; constructing a client LEO signal signature comprising samples over an LEO signature time period of the at least one client received LEO satellite signal; and transmitting the client MEO signal signature and the client LEO signal signature to a server for authentication of an asserted location of the client device. - View Dependent Claims (18, 19, 20)
