Abstract

A self-verifying identification card having an image area which may contain a portrait, a finger print, a retinal image, or all of these together with an image signature which is derived from scanned intensity measurements taken from the image area. In the verification process, the image is scanned and aligned with respect to reference points corresponding to the original printing process which created the card, and intensity values, their averages, or any other function are compared to information provided by the image signature. Mathematical transformations, such as a one-way hash, an encryption, a compression algorithm, or a truth table may be used to encode the image signature.
Alignment markers aid in scanning the image and the image signature. The use of average values aids in reducing noise and the use of comparison functions makes the process less sensitive to variations among scanners. The verification may be done at the point of a transaction, for a standalone system, or may be referred to a centralized data base in a networked system for further inquiry. In a networked system the image signature may be stored in the database.
