Abstract:
A method is provided for producing an authenticatable object that includes providing a decoder lens having a lens pattern and providing an array of image elements having an image pattern that corresponds to the lens pattern. The decoder lens is disposed a substantially uniform distance from the array of image elements such that the decoder lens reveals a visible image that includes at least a portion of the image elements, the image elements being adjusted in size by a zoom factor so that the visible image appears to float above a given plane when viewed at different angles through the decoder lens. Alternatively, the image elements may be adjusted in size by a zoom factor and selected image elements may be flipped so that the visible image appears to float above a given plane in different directions when viewed at different angles through the decoder lens.
Abstract:
Various examples are provided for creating encoded security images that are formed by embedding a multi-shade hidden or latent image into a visible image. The multi-shade latent image may include image content having a wide range of tonal values. An article of manufacture is provided having a surface with image elements thereon, the image elements include characteristics that correspond to a relative color or a relative shade of a source image for a polychromic or multiple shade latent image. The latent image is visible when the surface is viewed at glancing angles.
Abstract:
A system and method are provided for constructing an optical device having a substrate and a filter layer provided on the substrate. The filter layer includes features that render a first image and gaps between the features. An image layer is provided on the filter layer and includes image elements provided within the gaps between the features. The first image is rendered in reflected light and the second image is rendered in transmitted light. According to one example, a second filter layer may be provided on a second side of the substrate such that features of the filter layer and second features of the second filter layer may be at least partially out of vertical alignment in order to define a plurality of light ray entry angles.
Abstract:
A computer-implemented method is provided for creating an animation from a plurality of latent images encoded into a visible image, where the encoded visible image is visually similar to the visible image when viewed with a naked eye. The method includes generating, via a processor, a first latent image having a first pattern of elements and assigning a first encoding parameter to the first pattern of elements. A second latent image is generated having a second pattern of elements and a second encoding parameter is assigned to the second pattern of elements, wherein the second encoding parameter is different than the first encoding parameter. The first pattern of elements and the second pattern of elements are embedded in the encoded visible image for decoding using a decoder having decoding parameters that match the corresponding first encoding parameter and the second encoding parameter. The decoded first latent image and the decoded second latent image are sequentially displayed to reveal the animation.

Abstract:
An authenticatable object comprises a surface having a latent hidden image embossed therein. The latent image is an encoded version of an authentication image and comprises a plurality of elements applied to the surface with a predetermined frequency. The latent hidden image is configured for optical decoding by a decoder having a decoder frequency corresponding to the predetermined frequency.
Abstract:
An illuminated decoder is disclosed. The illuminated decoder is useful determining genuine items from counterfeit items by decoding encoded images printed on genuine items to reveal an authentication image in low light situations. The illuminated decoder includes a housing, a lens configured for optically decoding encoded images, and at least one light source attached to the housing.
Abstract:
A method of authenticating objects is disclosed. At least one object having a print region with printed material contained thereon is provided. The printed material of the print region includes a layer of non-visible indicia which emits at least one wavelength of light outside a visible range of an electromagnetic spectrum when stimulated with electromagnetic radiation. An optical image of the object is recorded with an imaging device to make the non-visible indicia perceivable to a human eye. The perceived image is then compared against expected authentication indicia to authenticate the object. A system for authenticating objects includes at least one imaging device to record optical images of objects having a layer of non-visible indicia and to render the non-visible indicia perceivable to a human eye. The system also includes a central authentication system in communication with the imaging device to receive optical images recorded by the imaging device.
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.
