Verifiable authentication services based on global navigation satellite system (GNSS) signals and personal or computer data

Abstract:

A verified authentication device has a navigation receiver, a processor, and a verification device. Navigation signals are transmitted from a Global Navigation Satellite System (GNSS). The processor authenticates the navigation signals and determines position coordinates of the navigation receiver. The verified authentication device receives input from a user of the verified authentication device. The verified authentication device provides reliability of the position coordinates based on the input from the user.
