Abstract
A method for authenticating an object is provided. The method comprises optically encoding an authentication image to produce an encoded image and applying the encoded image to an object in a layer of non-visible indicia to form a non-visible encoded image. The non-visible encoded image may be rendered visible and decoded to allow the authentication image to be viewed.
