In one embodiment of the invention, a device such as an MFP, a printer, a scanner, a copier, or a fax machine comprises or is connected to a card reader. The device prevents users from using the device until the users have been authenticated. In order to authenticate himself to the device, a user inserts his CAC into the card reader. The device reads the user's digital certificate off of the user's CAC. The device determines whether the digital certificate is valid. If the digital certificate is not valid, then, in one embodiment of the invention, the device prevents the user from using any of the device's functions (e.g., printing, scanning, copying, faxing, etc.).

  • Patent number: 8610958
    Abstract: The present invention enables creating authenticable continuous tone color multi-ink multi-halftone images offering means of verifying their authenticity. The invention relies on color halftones, color separation into different ink surface coverages for different halftoning methods, mapping of an input gamut into a gamut defined by a set of inks, calculating the optimal boundary between region halftones created with different halftoning methods, and color multi-halftone image generation. The basic authentication is performed by examining the color multi-halftone image under a reference illumination and verifying that the message incorporated within the color multi-halftone is hidden and revealed under a different illumination. Authentication can further be performed by observing the color multi-halftone image both in reflection and transmission modes and verifying that in one of these modes the message is hidden and that in the other mode the message is revealed.

The method involves creating a halftone image using two different halftone strategies. The halftone method is combined with a binary watermark mask to form two color patterns (e.g., one in a background region of the image and one in a watermark region of the image) and two successive-filling halftone algorithms, such that the ink droplets deposited by one color pattern cover more of the substrate than the ink droplets deposited by the other color pattern, with the two color patterns having approximately the same reflectance under normal light. However, under UV illumination, a visible difference (e.g., the watermark) is seen in the two patterns.

  • Patent number: 7884983
    Abstract: An image display body in which a decorative effect is obtained more effectively by an optical diffraction structure. In an image display body, an optical diffraction structure portion constituted by the optical diffraction structure in a halftone dot state is provided in a colored region on a base material. In the image display body, a dot area percent of a halftone dot a constituting the optical diffraction structure portion to the colored region ranges from 15% to 60%, an area of each halftone dot a is smaller than 0.25 mm2. The halftone dots 21a are diffused by an error diffusion method.

  • Publication number: 20100314861
    Abstract: 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.

  • Patent number: 7778437
    Abstract: Stationery, or other printable media, is encoded with a digital watermark. The watermark is not conspicuous to a human observer of the media, yet conveys plural bits of auxiliary information when optically scanned and digitally processed. The watermark can be formed by ink-jet printing, or otherwise. The encoded information can be used for various purposes, including authenticating the document as an original, linking to associated on-line resources, and distinguishing seemingly-identical versions of the same document (document serialization).

  • Patent number: 7706025
    Abstract: Provided herein are teachings directed to the creation of moiré-based auto-stereoscopic watermarks in rendered images. By choosing different halftone structures, which differ by having different spatial frequencies for each of two delineated partitions in an image, it becomes possible to embed arbitrary binary patterns into printed documents as digital watermarks. The invisible watermarks become moiré auto-stereoscopic images when the prints are viewed through an overlaid transparency “decoder” suitably prepared by virtue of being rendered with a uniform halftone structure having the correct special frequency in relationship with the partition frequencies employed in the printed document.

  • Patent number: 7604257
    Abstract: The printed product comprises a carrier (1) provided with a relief on the surface thereof in the form of a plurality of grooves and a main visible image transmitted by an ordered screen, wherein said relief and the screen structure of the visible image are embodied in such a way that at least one additional image becomes manifest on the main image background when a lighting or viewing angle is modified. According to the invention, the angle and period (d) of the groove tracing is equal to the angle and lineature of the main image screen, and geometrical distortions whose value corresponds to the value of tonal gradations of the additional image are introduced into the relief and/or the main image screen structure without breaking the continuity of the pattern lines forming said screen and relief, whereby a nonuniform system of cross-points of the grooves with the screen pattern lines (8) forming said additional image is created.

  • Publication number: 20090115184
    Abstract: A forgery-proof value document, in particular a postage stamp, is examined for its authenticity. The value document contains a two-dimensional area with a security element in the form of a two-dimensional structure. The two-dimensional area is provided with, for example printed with, at least one first and at least one other substance. When illuminated with light that is visible to the human eye, the two substances have the same hue and different hues when illuminated with infrared light. The security element is placed on the value document by use the first substance, the remaining part of the area by use of the at least one other substance. When illuminated with visible light the entire two-dimensional area appears in the same hue. When illuminated with infrared light the security element is optically distinguished from the remaining area.
