Abstract

The present invention provides a system and method for facilitating authentication and data/content integrity verification of printed documents underlying legal transactions and other documents requiring durability, including real estate and loan transactions, for example. A Unique Content Identifier parses the document one page (or other pre-determined segment) at a time. Each segment of the document is assigned a digit or group of digits, and each page or document segment can be provided with a single digit in the overall identifier. The entirety of digits associated with a document is aggregated into an authentication string. Upon receiving a request to process the document later, the present invention can authenticate and verify the integrity of the document by reading the presented document to obtain an authentication string, and then compare the new string with the previously stored string. Upon a successful match, the document is considered valid, authenticated and unaltered.
