System for verifying the integrity of a document

摘要

A system to verify the integrity of a document generates a member ID for each member that signs up to draft a document, generates a checksum code when the document is complete, either through inquiry of the member by the system or otherwise, and associates the checksum and member ID with the completed document. The system displays the member ID and checksum on the document whenever it is printed or displayed electronically. Upon inquiry of a member ID and checksum, the system returns information that the document is or is not the most recent version, or that it cannot be determined if the document is the most recent version. The checksum can be in the form of an alphanumeric string of characters, a bar code, or a 2-dimensional matrix code, and is at least in part based on the content of the document, or the length of the document.
