“Authentication Stamp” software converts the document image into a complex but tiny sub-image. This sub-image, similar but more compact than a bar code, contains a “virtual” image of the original. Confirmation occurs when the document is rescanned and the “Authentication Stamp” is compared to the balance of the document.
Falsifiers who want to alter documents use the best tools available. Up to now, they simply scan in a document and use image editing tools to change the document. For example, a transcript could be scanned and an “F” turned into an “A”. It would be very difficult to detect the change in the newly printed document.
However, if a “Authentication Stamp” were printed on the document’s original copy, the forger would not be able to change the document without detection. A simple scan at an authentication system would detect the forgery. The difference between the “Authentication Stamp” and the altered document is automatically detected. In fact, the “Authentication Stamp” could tell the authenticator exactly where the alterations were made and what the original document looked like.
