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.

Abstract: A method for providing verified authentication services is presented. The method utilizes a verified authentication apparatus comprising a radio navigation receiver, a navigation processor, and a verification device. The method comprises: (A) receiving an authenticated navigation signal transmitted from a radio positioning system by using the radio navigation receiver, (B) obtaining the position coordinates, velocity and timing coordinates of the radio-navigation receiver by using the navigation processor, and (C) verifying reliability of the obtained position coordinates, velocity and timing coordinates of the radio navigation receiver by using a verification device; wherein a verified authentication service is provided.
