1. A system for determining the authenticity of a client seeking access to a host comprising:
- a client authentication device, comprising;
first sensor locationally associated with the client for sensing transmissions from two or more signal sources that produce constantly changing transmissions containing information sufficient to derive a state vector that identifies the client location, said first sensor including a converter for converting the sensed transmissions into first state vector observations for communication to an authentication server associated with the host, and circuitry for communicating the first state vector observations to the host authentication server; and
wherein the host authentication server, comprises;
an authentication processor for receiving and processing the first state vector observations and for comparing one or more attributes of the state vector contained in the first state vector observations to predetermined authentication criteria, and circuitry for developing a user authentication signal when the one or more attributes of the first state vector observations satisfy the predetermined authentication criteria.

Abstract
A method and apparatus for authenticating the identity of a remote user entity where the identity of such user entity is authenticated by use of information specific to geodetic location of the user entity but that changes constantly, making "spoofing" the host device extremely difficult. The invention is preferably implemented utilizing satellite positioning technology to produce the identifying information.

18. A system for applying to an electronic message existing at a client location and intended for a destination information for determining the authenticity of that message comprising:
-
a sensor locationally associated with the client for sensing transmissions from two or more signal sources that produce transmissions containing information sufficient to derive a state vector that identifies the client location, said sensor including a converter for converting the sensed transmissions into state vector observations for communication to the destination; circuitry for associating with the message the sensed state vector observations from the sensor; and circuitry for sending the message towards its destination with the sensed state vector observations. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
