Abstract
A method for deterring forgeries and authenticating signatures placed on any document or other object (collectively "Item") is disclosed. A first two dimensional bar code or forgery-proof diffraction grating pattern or similar information bearing medium (Electronic Fingerprint or "EF") is issued to a person whose signature is being protected ("Principal") by a central registrar ("CR"). A personal identification number ("PIN") which has been assigned by the CR to the Principal is encoded on the EF. The PIN remains constant and is encoded on all EFs distributed to the Principal.
