Knowledge based system for document authentication
First Claim
1. In a data processing system that includes a processor, at least one data terminal and at least one data communication port, a document authentication system comprising:
- means for interconnecting said at least one data terminal with said processor;
means, responsive to a first user activating said at least one data terminal to transmit a document origination signal from said at least one data terminal via said interconnecting means to said processor, for transmitting a document, identified by said document origination signal, from said processor to a second user via said data communication port;
means, responsive to receipt of a document authentication signal transmitted to said processor by said second user to acknowledge acceptance of said document by said second user, for comparing said received document authentication signal with said document to determine whether said received document authentication signal contains document acknowledgement data that matches corresponding data in said document, including;
means for identifying differences between said document acknowledgement data contained in said received document authentication signal and said corresponding data in said document,means for storing data indicative of a set of predetermined thresholds, each threshold in said set of thresholds corresponding to a maximum allowable variation in one of said corresponding data in said document,means for indicating a match between said received document acknowledgement data and said document when said identified differences do not exceed said maximum allowable variation for each of said corresponding data; and
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 authenticating 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.

10. In a data processing system that includes a processor, at least one data terminal and at least one data communication port, a method of document authentication comprising the steps of:
-
interconnecting said data terminal with said processor; transmitting, in response to said first user activating said data terminal to transmit a document origination signal from said data terminal to said processor, a document, identified by said document origination signal, to a second user via said data communication port; comparing, in response to receipt of a document authentication signal transmitted to said processor by said second user to acknowledge acceptance of said document by said second user, said received document authentication signal with said document to determine whether said received document authentication signal contains document acknowledgement data that matches corresponding data in said document, including; identifying differences between said document acknowledgement data contained in said received document authentication signal and said corresponding data in said document, storing data indicative of a set of predetermined thresholds, each threshold in said set of thresholds corresponding to a maximum allowable variation in one of said corresponding data in said document, indicating a match between said received document acknowledgement data and said document when said identified differences do not exceed said maximum allowable variation for each of said corresponding data; and authenticating, in response to said step of comparing determining a match between said received document authentication signal and said corresponding data in said document, said document. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
