    Abstract: An automated method of producing an encoded image for use in authenticating a printed version of a digital document is presented. The method comprises establishing at least one digitized authentication image, receiving at least one user-supplied encoding parameter, and determining at least one non-user-supplied encoding parameter. The method further comprises establishing a first encoding parameter set including the at least one user-supplied encoding parameter and the at least one non-user-supplied encoding parameter. The first encoding parameter set is usable to encode one or more of the at least one digitized authentication image. The method also comprises encoding one or more of the at least one digitized authentication image using the first encoding parameter set to produce a final encoded image.

The authentication image is viewable using a decoder lens having one or more decoder lens frequencies. The method comprises generating a first plurality of component images in which corresponding tonal areas are tonally balanced around at least one tonal value. At least one of the component images is configured to include a representation of the authentication image. The method further comprises determining a pattern of component image elements for each of the component images. The pattern having at least one element frequency that is equal to or a multiple of a decoder lens frequency. At least a portion of the content of each component image element is extracted and used to construct a composite image element.

    Abstract: A reflective decoding device is provided for use in decoding an encoded image comprising a latent image encoded using at least one encoding parameter. The device comprises a substrate with a reflective surface portion having a surface topography comprising a predetermined pattern of topographical features. The predetermined pattern is configured with at least one geometric characteristic corresponding to the at least one encoding parameter so that placement of a light-transmissive sheet having the encoded image formed thereon over the predetermined pattern of topographical features allows the latent image to be viewed.

    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).
