Abstract:
A sheet comprising a fiber substrate and at least one ribbon defining at least one zone of reduced opacity, the sheet including at least two complementary security elements situated respectively on either side of said at least one ribbon and of complementarity that is observable in show-through by virtue of the zone of reduced opacity.
Abstract:
An image presentation system employing microstructured icon elements to form an image. In one form a synthetic optical image system is provided that includes an array of focusing elements, and an image system that includes or is formed from an array or pattern of microstructured icon elements, such as those described below, wherein the microstructured icon elements are designed to collectively form an image or certain desired information, and wherein the array of focusing elements and the image system cooperate, for example through optical coupling, to form a synthetic optical image which image may optionally be magnified. In another form an image presentation system is provided that includes or is formed from an array or pattern of microstructured icon elements, such as those described below, wherein the microstructured icon elements are designed to collectively form an image or certain selected information, and wherein the image system is designed to stand alone and be the image viewed or the information read by use of a magnifying device, such as a magnifying glass or microscope, that is provided separately from the image system.

Abstract:
The invention relates to an authentication medium capable of eliminating problems with the formation of an authentication portion with and embossed hologram, for instance, difficulty with which fabrication time is cut down, and difficulty with which an authentication pattern is changed due to an increased step counts at the time of embossing mold fabrication. A thin-film layer(2) made up of a material that changes in transmittance of reflectance upon heating, an orientation film (4) that is provided if necessary, and a color change layer (3) such a light selective reflecting layer comprising a cholesteric liquid crystal layer are stacked on a substrate (12). By means of a thermal head or the like, recording is applied to the thin-film layer (2), and changes in the hue of the light selective reflecting layer (3) at a recorded site or the presence or absence of reflection or hues upon observation by way of a circular polarization sheet are observed, thereby solving the above problems.
Abstract:
An apparatus and method for securely providing identification information generates one or more obscured identifiers for a recipient, such as one or more identifiers that are generated based on data unique to a recipient or other information as may be appropriate. In one embodiment, the method and apparatus generates a translucent identification member, such as a plastic card, sheet, film or other suitable member that has a translucent area that includes one or more obscured identifiers. When the translucent identification member is overlayed on a screen displaying a visual filtering pattern, one of one or more obscured identifiers is visually revealed for use during the particular transaction. The revealed identifier is entered into a recipient device and sent to an authenticator to be verified as an appropriate identifier for the transaction.
Abstract:
The invention relates to a security element for security papers, documents of value, ID cards or the like that is of self-supporting design and has two different security features. The security features are disposed on opposite sides of the security element, at least one the security features being optically variable.
Abstract:
A security device comprises a substrate (1) having a viewing region (3) which is provided on one side with first indicia (7) and on the other side with second indicia (9) overlying the first indicia. The substrate carries an obscuring material (10) aligned with the second indicia (9) so as to prevent at least the second indicia from being viewed from the one side of the substrate under reflected radiation. The substrate is sufficiently transparent while the obscuring material permits the passage of sufficient transmitted radiation to allow the second indicia (9) to be viewed from the one side of the substrate under transmission conditions.
Abstract:
A security document such as an identification card including a base layer having at least one surface bonded and security markings printed on that surface. The bonded surface is covered by a protective layer including a film of material fused thereto so as to form a matrix encapsulating the printed security markings (which may include a xerographically reproduced photograph).
Abstract:
A method for producing a document blank or a security document includes providing a substrate layer having a metal layer or applying a metal layer to a substrate layer, forming a color-effective pattern in or on the metal layer, in which the pattern has a pixel structure and each pixel includes at least two subpixels which cause a monochromatic color effect, and joining together the substrate layer and at least one further transparent substrate layer to form a document body. A security document blank, a personalized security document and a method for the laser personalization of security document blanks in color are also provided.
Abstract:
A light control film is described that is formed with at least one security feature therein. The security feature is not visible when the film is viewed at an incorrect angle. The security feature only becomes visible when the film is viewed at the correct viewing angle or range of viewing angles. A plurality of security features can be formed in the film at substantially the same location(s), but at different angles, so that each security feature only becomes visible when the film is viewed at the correct respective viewing angle or range of viewing angles. The light control film can be integrated into any type of document where resistance to counterfeiting and fraudulent alteration are important, such as plastic identification or credit cards, or passports.
