摘要:
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.

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.

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.

摘要:
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.

A security material for documents comprises a first layer of material, such as a polymeric film or laminate, having first and second sides. A pearlescent material is applied to at least one of the first and second sides. The pearlescent material defines a pattern comprising at least two different colors that are at least partially interlocked in the pattern, and the pattern permits printed information that is overlaid by the pattern to be effectively perceived.

An identification card is prepared by attaching an antenna and integrated circuit chip onto a core layer of polyolefin, attaching a bottom sheet to the core layer thus encasing the antenna and integrated circuit chip, providing an image-receiving layer on one or both outer surfaces of the resulting sandwich, and laminating a protective layer or layers over the image-receiving layer(s). The identification document displays improved durability, ease of manufacture and protection of the electronic components.

An identification document is provided comprising a printable layer, a computer readable data storage element, and a computer readable calibration element. The computer readable data storage element is formed on the printable layer and comprises a plurality of pixels, wherein each pixel has one of a predetermined plurality of colors. The computer readable calibration element is formed on the printable layer and comprises a plurality of pixels and includes information enabling a determination of the pixel size in the computer readable data storage element and also a determination of at least a portion of the predetermined plurality of colors.
摘要:
The present invention provides an emerging security or authentication feature for identification documents and other objects. The security feature is constructed using two differently emission-decaying inks. The inks are arranged so as to convey a first pattern when they are both exited. A second pattern emerges as a first and more rapidly decaying ink decays, but while a second and relatively longer decaying ink still provides emissions. The second pattern can be alphanumeric characters, a barcode, a pattern that will yield a predictable frequency domain representation, a digital watermark, etc. In one implementation, the first pattern is a first machine-readable code and the second pattern is a second, different machine-readable code.
