  • Process to secure a personal portable object
    Patent number: 8538067
    Abstract: The invention relates to a process to make secure a personal portable object comprising a body of the personal portable object, a microchip, a printed image and a device to enable said personal portable object to communicate with an entity external to the device. The process includes using an image file and an insertion algorithm to generate an image feature vector Vsi(num), storing the image feature vector Vsi(num) in the microchip, using the printed image obtained by a scanning device to generate an image feature vector Vsi(dig), and using a read-back algorithm to match the image feature vector Vsi(num) and the image feature vector Vsi(dig).

  • Method and apparatus to mark a document using a combination between guilloches and watermarking, method and apparatus to read previous combination
    Patent number: 8406459
    Abstract: Guilloches (preventing modification) and watermarking (preventing substitution) technologies are combined to protect a medium, such as a card or a passport. The major idea stems from their dual role for medium authentication: the presence of one is needed to check the validity of the other one. By nature, the guilloche network is visible in the image and easily detectable by image processing. This network is therefore used to generate reference points as elements of synchronization to retrieve watermark information originally embedded in the medium that has submitted an RST transformation. These reference points are by nature stronger than any other means involving invisible templates in the spatial or Fourier space.
