Abstract: A self-authenticating article comprising a substrate having an image receiving surface and a lenticular lens is provided. The lenticular lens has a predetermined lens frequency and is configured for optically decoding encoded indicia viewed therethrough. The lens is attached to the substrate so that the lens can be selectively positioned to overlie the image receiving surfac to decode encoded indicia printed thereon. The self-authenticating apicle further comprises an encoded image on the image receiving surface, the encoded image comprising at least one of th set consisting of printed indicia and indicia formed as variations in surface geometry of the imæ receiving surface. The surface geometry variations may comprise raised and non-raised areas surface areas that combine to define at least a portion of the indicia.

Abstract: A method is presented for decoding an encoded image produced from a primary image and at least one secondary image using at least one encoding parameter. The encoded image is formed so that when the encoded image is printed, the secondary image is not discernible to a viewer without an optical decoding device having characteristics corresponding to the at least one encoding parameter. The method comprises obtaining a digital version of the encoded image (S110), determining the at least one encoding parameter (S130), and constructing a decoded image from the digital encoded image using at least one of the encoding parameters in the encoding parameter set (S160).

Abstract: An illuminated decoder is disclosed. The illuminated decoder is useful determining genuine items form counterfeit items by decoding encoded images printed on genuine items to reveal an authentication image in low light situations. The illuminated decoder includes housing, a lens configured for optically decoding encoded images, and at least one light source attached to the housing.
