  • 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: 7374484
    Abstract: In a method for manufacturing instant lottery tickets where book numbers and ticket numbers are printed on the tickets utilizing a dual security process such that the book numbers are shuffled in each pool before the tickets are printed to break the link between the book numbers the ticket numbers or validation numbers, a reversing process can be used under certain predefined conditions to relate the original book numbers to the ticket numbers or validation numbers. In one example, where a shuffling algorithm utilizing seeds is used to shuffle the book numbers, the seeds used in the algorithm are maintained in an encrypted file. A decryption key for the encrypted seed file can be used by a lottery administration or trusted third party to reconstruct game play indicia for game adjustment purposes and manufacturing adjustments.

  • 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: 7193744
    Abstract: Conventionally, when counterfeit judgment processing by using electronic watermark is performed in a printer driver, a printing speed is lowered due to heavy load. To solve the problem, in the printer driver, first, it is judged whether or not image data indicated by input print information is in high quality. If the image data is in high quality, it is judged whether or not the image data represents a particular image. If the image data represents the particular image, predetermined processing is performed on the image data. This minimizes the execution of counterfeit judgment processing and reduces the load.

  • Patent number: 6859534
    Abstract: This invention relates generally to a method and apparatus, as implemented by a software program on a computer system, for digitally producing counterfeit-deterring scrambled or coded indicia images, typically in a printed form. This method and system are capable of combining a source image with a latent image so the scrambled latent image is visible only when viewed through a special decoder lens. The digital processing allows different latent images to be encoded according to different parameters. Additionally, latent images might be encoded into single component colors of an original visible image, at various angles from each other. A second embodiment teaches a method of forming an optical surface having diffraction properties that vary over the optical surface in accordance with a security graphic image that includes an encoded recognizable indicium formed as a parallax panoramagram image through a lenticular line screen.

  • 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.
