Abstract: Particles conveying a code are incorporated into polymer matrix to form a core document substrate. These particles may be colored to create a distinctive look of the document that makes it unique for a particular document issuer and enables visual authentication. Addition of a covert attribute to the particle, such as a UV pigment or hidden layer of material, allows a covert, forensic characteristic and it also allows a mathematical description to be calculated describing the random distribution of a specific area on a document and then captured on it (e.g., in the bar code or magnetic stripe or digital watermark on an ID document).

Abstract: The invention provides a composition having laser engraving properties, comprising a host material and an effective amount of a laser enhancing additive. The laser enhancing additive comprises a first quantity of least one of copper potassium iodide (CuKI3) or Copper Iodide (CuI), and a second quantity at least one substance selected from the group consisting of zinc sulfide (ZnS), barium sulfide (BaS), alkyl sulfonate, and thioester. The composition can be engraved with grayscale images by an Nd:Yag laser and can be added to laminates or coatings. The composition can be used during the manufacture of many articles of manufacture, including identification documents.

Abstract: An image destruct material comprises a release layer positioned between an image receiving layer and a base layer. The adhesion between the release layer and the base layer is greater than adhesion between the release layer and the image receiving layer. The release layer material can be used in secure documents that have an image receiving layer. After information is printed on the image receiving layer, an overlaminate is applied over it. Removal of the overlaminate destroys the printed image on the receiving layer because of the relative adhesive properties of the image receiving layer, overlaminate and release layer.

Abstract: The invention relates to identification documents, and in particular to providing optically variable personalized data to identification documents. In one implementation, we provide an identification document comprising a document layer and a first indicium. The document layer comprises a material capable of being printed by a thermally transferable optically variable ink. The first indicium is printed on the document layer and comprises personalized data and printed to the document layer by a thermally transferred optically variable ink. The first indicium may be printed to the document layer by disposing a thermally transferable optically variable ink in a mass transfer panel of a printer ribbon adapted for use in a dye diffusion thermal transfer printer, and printing the first indicium as part of a mass transfer printing process.

Abstract: The invention provides hard coat and image receiving layer structures and related methods used in ID document production. These structures and methods provide ID documents that offer hard protection in areas where needed (e.g., in optical windows for machine readable data), and also provide image receiving layers for later printing of variable data, such as personalization information of the bearer. Implementations of the structure provide an effective interface between hard coat and image receiving layers that provides enhanced durability in manufacture and field use.

Abstract: An identification document which includes anti-counterfeiting features to provide tamper evidence in response to counterfeiting attempts includes an image receiving area having one or more fixed or variable items of information. In one embodiment, a pattern of material is embedded into the image receiving layer in the vicinity of the one or more fixed or variable items of information in a predetermined configuration. The embedded pattern is comprised of a solvent insoluble material such that attempted delamination of the document using solvents results in visually detectable tampering.

Abstract: An identification document manufacturing method makes an identification document with an optically variable security feature by forming a lens structure in the document's lamination layer along with image information. The method provides image information arranged to include at least two different images. The method uses pressure to form a lens profile in a laminate, including combining the laminate with ink representing the image information to form the document. The document is formed together with the laminate and ink such that the lens profile enables display of the at least two different images when the document is viewed at different predetermined angles. An information bearing document comprises a core layer, an image layer depicting at least two different images, and a laminate layer. The laminate layer is pressed on the core layer such that it forms a lens profile that enables display of the at least two different images when the document is viewed at different predetermined angles.

Abstract: The present invention provides identification documents with security features. For example, a document may include two or more inks that are designed to cohesively fail upon a de-lamination attack. A resulting failure pattern is preferably difficult to predict. The two or more inks are applied to an identification document including a core and laminate layer. At least one of the inks is characterized such that an adhesive strength of the ink to the core and an adhesive strength of the ink to the laminate layer is each greater than the cohesive strength of the ink itself. Thus, the ink rips apart in a somewhat random-like manner upon a de-lamination attack. The ink can be arranged in interwoven or interlocking patterns or in other desired patterns and locations.

Abstract: An identification document includes a lens system and a specially prepared photo of a document bearer. The lens system and the specially prepared photo cooperate to create a three dimensional photo effect. The document includes two or more document layers. There is a lens structure in one of the document layers, and it includes lens elements. A photo is printed on one or more of the document layers. The photo depicts the document bearer, and includes two or more separate images of the bearer from different perspectives. Parts of the separate images are interleaved together into sets, and the sets are positioned relative to corresponding lens elements of the lens structure. These sets include parts of the separate images such that when viewed through the lens structure, the parts are viewed simultaneously making the subject appear three-dimensional to a viewer.

Abstract: A security feature for an identification document comprises a base document layer, including a first image printed with a covert ink, and a personalized image relating to a bearer of the document (such as a facial photo) printed over the first image. The personalized image is printed with an ink that is incompatible with the covert ink such that the first image becomes overt within the personalized image upon printing of the personalized image. This feature creates an interlocking relationship between the covert image, which may be pre-printed prior to personalization on card stock, and personalized information printed over the covert image. Variations of this feature can be made in which the first image is not covert, yet still creates an interlocking relationship due to ink incompatibilities. Further, the second image may depict information other than personal information.

The method includes: providing a substrate constructed and arranged to receive printing thereon; printing a first variable indicium on the substrate, where the first variable indicium is not visible to the human eye in ambient light but is visible to the human eye when viewed using a first type of light; and printing a second variable indicium on the substrate, the second variable indicium being visible when viewed using ambient light. Other methods, systems and documents are provided as well.

Abstract: One aspect of the invention comprises a method of embedding data in a code readable by machine from a visible light scan of the code. The method comprises pre-printing a two dimensional array of pixels on a substrate. The pixels include at least one calibration pixel, and each have color values. The method selectively alters at least a subset of the pixels by using laser radiation to alter color saturation of the color values of the pixels in the subset relative to the calibration pixel according to digital data values of the code to be embedded in the subset of pixels. This method has been adapted to embed personalized information in pre-printed graphic elements on ID cards.
