Patent ID: 8037307

Claim:
A system for providing an authentication code across a network for use in a game document comprising: one or more terminals that each include a document printing device, each terminal including a pseudo-random key generator configured to generate a key wherein the key remains at the terminal that generated the key and is not disclosed to the remainder of the network, each terminal configured for selectively receiving a bet for entry into a game and generating a game-entry document having document-specific information, each terminal further configured for generating a document code comprised of a mathematical function utilizing at least the key and a bet for a specific game entry, and each terminal configured for selectively transmitting the document-specific information and document code to another computer device on the network; at least one server in communication with the network, the server configured for receiving the document-specific information and document code transmitted from the one or more terminals, storing such document-specific information and code, and sending the one or more terminals an authentication code comprising at least a serial number for printing on a game document; and wherein upon receipt of the authentication code from the at least one server, each terminal configured for printing a game document including the received authentication code and deleting the key so that it no longer remains at each terminal so that neither the terminal or the server may reproduce the key.
