20120091704 | IDENTIFICATION DOCUMENT COMPRISING A SECURITY PATTERN - The invention relates to an enhanced security feature for identification document. For that, the identification document comprises at least two constitution layers, a first specific coating ( | 04-19-2012 |
20110298205 | IDENTIFICATION DOCUMENT WITH AN IMPROVED ANTI-COUNTERFEITING ELEMENT - An identification document including a translucent portion is provided. The translucent portion has a first side and a second side, and includes a first personalized information. The first personalized information includes a second personalized information which is hidden in the first personalized information when viewed from the first side of the translucent portion. A filtering device is attached to or formed in the second side of the translucent portion. The filtering device is configured to reveal the hidden second personalized information. The second personalized information appears superimposed onto the first personalized information when viewed from the second side of the translucent portion, and remains hidden when viewed from the first side of the translucent portion. | 12-08-2011 |
20110158472 | METHOD FOR SECURING AN IMAGE BY MEANS OF GRAPHICAL ANTI-COUNTERFEITING MEANS, METHOD FOR SECURING AN IDENTIFICATION DOCUMENT, AND SECURE IDENTIFICATION DOCUMENT - The invention relates to a method for securing a first image by means of graphical anti-counterfeiting means and to a method for securing an identification document with such graphical anti-counterfeiting means. The invention also relates to a secure identification document that allows detecting either a fraudulent modification of the existing personalization or a fraudulent falsified document. For that, graphical anti-counterfeiting image is inserted into an identification image, each image being defined by a plurality of pixels. The characteristic level (for example grey level) of each pixel i of the graphical anti-counterfeiting image is linked, by a function F, to a matrix Ωi of pixels defined in the identification image, said pixels of the matrix Ωi surrounding the location i of a pixel of the graphical anti-counterfeiting image, said function F taking into account the characteristic level (for example average grey level) G(Ωi) and the texture level T(Ωi) of said matrix Ωi. | 06-30-2011 |
20100260372 | METHOD AND APPARATUS TO MARK A DOCUMENT USING A COMBINATION BETWEEN GUILLOCHES AND WATERMARKING, METHOD AND APPARATUS TO READ PREVIOUS COMBINATION - 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. | 10-14-2010 |
20100165414 | METHOD OF SUPERIMPOSING AN IMAGE ONTO ANOTHER, METHOD OF PERSONALIZING A DATA CARRIER USING THE IMAGE SUPERIMPOSING METHOD AND A PERSONALIZED DATA CARRIER - A method of superimposing a first image onto a second image, wherein each image is defined by a plurality of pixels is disclosed. The method includes changing target pixels of the second image corresponding in position to pixels of the first image to be superimposed on the second image. Changing target pixels of the second image includes changing the values of some of these target pixels of the second image to respective new values. Each new value is based on the original value of at least one pixel of the second image. A personalization method including such an image superimposing method and a data carrier thereby personalized are also disclosed. | 07-01-2010 |
20100164220 | Secure Identification Document and Method for Producing It - The invention relates to a secure identification document having two main surfaces (S | 07-01-2010 |
20100104801 | Method for Producing a Data Carrier and Data Carrier Produced Therefrom - A method for producing a data carrier with a see-through portion is disclosed. The method includes applying a layer of separation material ( | 04-29-2010 |
20100047488 | DATA CARRIER WITH SEE-THROUGH WINDOW AND METHOD FOR PRODUCING IT - A data carrier is provided having a see-through portion ( | 02-25-2010 |
