20100314861Authentication with built-in encryption by using moire parallax effects between fixed correlated s-random layers - This invention discloses new methods and security devices for authenticating documents and valuable products which may be applied to any support, including transparent synthetic materials and traditional opaque materials such as paper. The invention relates to parallax moire shapes which occur in a compound layer consisting of the superposition of specially designed and possibly geometrically transformed s-random base layer and s-random revealing layer with a small gap between them. The base and revealing layers are formed respectively by base layer element shapes and revealing layer sampling elements positioned at s-random locations, where the base layer locations and the revealing layer locations are strongly correlated. When tilting the compound layer or changing the viewing angle, a parallax moire intensity profile of a chosen shape is seen moving in the superposition, thereby allowing the authentication of the document. A major advantage of the present invention is in its intrinsically incorporated encryption system due to the arbitrary choice of the s-random number sequences used for defining the positions of the specially designed base layer element shapes and revealing layer sampling elements that are used in this invention.12-16-2010
20130181435Synthesis of authenticable halftone images with non-luminescent halftones illuminated by a luminescent emissive layer - A method and computing system are proposed for producing an authenticable security device with two sides. The verso side is covered with a luminescent emissive variable intensity layer formed for example by invisible luminescent ink halftones and the recto side is covered with transmissive non-luminescent ink halftones. The backlit colors resulting from the emissions of the luminescent layer or resulting from illumination by normal white light through the transmissive non-luminescent ink halftones are predicted by a backlighting model. This model enables computing the surface coverages of the luminescent and/or non-luminescent ink halftones in order to obtain a desired color either under excitation light (UV light) or under normal white light. This enable creating authenticable backlit images substantially similar to pre-stored reference images, either under normal white light, under excitation light, or under both the normal white light and the excitation light.07-18-2013
