  • Patent number: 10078773
    Abstract: Embodiments are directed to methods and systems to increase flow and throughput of particular data through the use of a machine readable code with portion analysis. The machine readable code may be generated by a transaction processing network and correspond with one or more resource provider computers. When data is received by the transaction processing network that corresponds with one of the resource provider computers, a portion of the machine readable code that is proportional to a size or measurement of the data may be provided in exchange for the data. The recipient of the portion of the code and, once the recipient collects a predetermined number of machine readable code portions to complete the machine readable code, the complete machine readable code may be scanned and transmitted back to the transaction processing network to be exchanged for additional information or to initiate further processing.

  • Patent number: 9033245
    Abstract: A device is described for the hiding and subsequent recovery of visual information. The device comprises two or more tokens (1), each containing a mask (2,3) of coloured pixels (4), are overlaid (5), so that when the pixels are aligned, hidden information, invisible in the individual tokens. The hidden information consists of one or more recognisable alphabetic, numerical or pictorial characters (6). During token overlay and alignment, the information becomes recognisable because it is made up of pixels whose colour is differentiated from the other pixels in the overlay. The information is hidden by adding pixels of certain colours. When the tokens are overlaid and the pixels aligned, the added pixels are effectively subtracted, revealing the hidden information. The tokens may be printed on various media, or may be displayed on an electronic device.

  • Patent number: 8645281
    Abstract: A process for authenticating an end user. A first pattern of colored quadrilaterals is generated. A second pattern of multiple colored nodes that include a first subset of nodes is generated. The first and second patterns are sent to the end user. If a transparent credit card is overlaid by the end user on top of the second pattern, then a second subset of nodes in the credit card would match in color and location the first subset of nodes. The authenticity status of the end user is determined by determining whether each node of a third subset of nodes within the second subset of nodes (i) corresponds to a unique node of the multiple colored nodes and (ii) has a color that matches a specific color in one quadrilateral of the colored quadrilaterals. The determined authenticity status is sent to the end user via an output device.

    Abstract: A sensing device for authenticating an object. The device includes a sensor for sensing coded data provided on or in a surface associated with the object. The coded data encodes an identity and, at least one part of a signature, the signature being a digital signature of at least part of the identity. The sensed coded data is then used by a processor, to determine a sensed identity and at least one sensed signature part, which are then in turn used to authenticate the object. The processor may form part of the sensing device, or be connected to the sensing device via a communications system.

  • Patent number: 7362860
    Abstract: This invention allows the encryption side to set whether an image playback apparatus should play back image data in a scrambled state or a non-scrambled state. When a code-block of input image data is an object to be encrypted, it is encrypted. In playing back the data, it is determined whether playback is to be executed by using the encrypted code-block (the scrambling playback mode is to be set). To inhibit use of the encrypted code-block, a terminating marker is placed at the start of the code-block. To use the encrypted code-block, the terminating marker is placed at the end of the code-block.

  • Patent number: 7114750
    Abstract: The present invention provides a durable and self-verifying secure document system and a method for its production, wherein counterfeiting is prevented. The secure document system is potentially useful for a wide variety of documents including, but not limited to, lottery tickets, currency, traveler's checks, passports, stock and bond certificates, bank notes, driver's licenses, wills, coupons, rebates, contracts, food stamps, magnetic stripes, test answer forms, invoices, tickets, inventory forms, tags, labels and original artwork. The instant invention provides a plastic paper substitute having various indicia associated therewith including visible and hidden indicia. Application of the hidden indicia to the plastic paper substitute is implemented in accordance with a computer software program, and the document includes an integral lens area which is particularly designed to verify the document's authenticity by rendering the hidden indicia visible to the viewer.

  • Patent number: 7040664
    Abstract: A self-verifying security document, such as a banknote, comprises a flexible sheet formed from a plastics substrate bearing indicia. The sheet has a window of transparent plastics material that includes self-verification means for verifying a security device provided at a laterally spaced second portion of the sheet when the sheet is bent or folded to bring the window into register with the security device. The self-verification means may be an optical lens for reading an area of microprinting. In another embodiment, the self-verification means may be an optical filter for viewing an area printed with metameric inks. In other embodiments, the self-verification means and the security device may be polarizing windows or Moire inducing patterns.

  • Patent number: 6826289
    Abstract: In the attribute detection apparatus in the system of the present invention, an inputted image is transformed by DCT means to extract an estimation value of the embedded electronic watermark data in frequency space. Then, the statistical similarity between known electronic watermarks and the extracted electronic watermark data are calculated. The attribute change apparatus in a system of the present invention comprises a selector, an insert data register for storing the output of the selector, a brightness register for storing the brightness signal of the inputted image, a color difference register for storing the color difference signal of the inputted image, and adder for adding the output of the color difference register and the output of the insert data register. Here, the selector selects one of the insert data stored in a plurality of memory areas on the basis of the attribute inputted from attribute detection apparatus.

  • Patent number: 6792110
    Abstract: The invention relates to an apparatus and method for enhancing the security of selected information associated with a negotiable document, such as the monetary value of a cheque. In the invention, one or more security features are printed or applied onto the cheque. One such security feature is an encrypted control code. The preferred embodiment employs a secret key cryptographic scheme to encrypt the monetary value and thereby generate a first control code which is printed on the check. When the check is presented for payment, a validator, such as bank or cheque clearing house, employs a verification system having a copy of the encryption key to read the monetary value from the cheque and re-encrypt it according to said scheme to generate a second control code. The cheque is not honored if the first and second control codes are not identical. Another security feature is a security image, composed, for instance, from a foreground image of the monetary value superimposed over a background motif image.
