Knowledge based system for document authentication (apparatus)
First Claim
1. In a data processing system that includes a processor that serves a plurality of users at one or more data terminals and one or more data communication ports, a document authentication system comprising:
- means for interconnecting a first user and a second user with a document stored on said processor;
means responsive to said second user transmitting a document authentication signal to said processor for disabling both said first and said second users from modifying said document;
means for comparing said received document authentication signal with said document to determine whether said received document authentication signal contains data that matches corresponding data in said document;
means responsive to said comparing means determining a match between said received document authentication signal and said corresponding data in said document for authenticating said document.

Abstract
The document authentication apparatus provides document authentication and authenticity capability. Document authentication requires that the person to be charged apply an authentication mark on the document indicating intent to authenticate the document. This requirement is analogous to a signature on a printed document and is implemented in the document authentication apparatus electronically through the use of both hardware and software. A program which immediately checks the identicalness of the document at the transmitting and receiving station through a high speed comparison, locks in the document such that no modification can occur and then awaits authentication handshakes from the two end points. Such authentication is real-time and can be both hardware and software executable, i.e., password and physical confirmation.
