  • Patent number: 7022385
    Abstract: The present invention provides a method for manufacturing an identification document that can contain both common information and unique information describing the specific document holder. The information is in the form of indicia applied by digital imaging means. The document itself is in the form of a laminated article having the information affixed to one or more internal layers. Attempt to gain access to these internally imaged layers causes the image to be sufficiently disrupted as to prevent modifying such images.
