The object of this invention is a method for securing an electronic document. In particular, this invention relates to a method that prevents the forging of documents in which an electronic chip is incorporated. To that end, the invention proposes a method in which the data on the document medium are associated with a fingerprint of the document, so as to make them inseparable. That fingerprint is determined on the basis of measurable physical units of the electronic chip or the medium. Thus, the invention allows the combination of the physical protection of the document and the protection of the chip so as to reinforce the security of said documents.

Method for securing an electronic document

This invention relates to a method used by an authorized user for the verification of a document having electronic verification means, The method comprises the various steps consisting in:&#x2014;reading, with electronic reading equipment with which the authorized user is equipped, of information stored in the electronic verification means of the verified document;&#x2014;transferring verification information, established on the basis of the information saved in the electronic verification means, from the electronic reading equipment to a viewing device of the authorized user, which viewing device is positioned, in normal conditions of use, in front of the eyes of the authorized user, the said viewing device being transparent to allow the said authorized user to see through it.

Method for verifying documents and device implementing such a method

The invention relates to a secured identity document having an externally readable chip storing a cryptographic configuration of the chip, defining the cryptographic security levels supported by the chip, for establishing a secure communication with a controlling terminal, storing a private key of a cryptography key pair and adapted to cipher data based on the stored private key; a support to which the chip is fastened, the support having a machine optically readable area, the data encoded in this area including the cryptographic configuration of the chip for establishing a secure communication with a controlling terminal in non ciphered form and the cryptographic configuration of the chip ciphered based on said private key.

System providing an improved skimming resistance for an electronic identity document

The invention relates to a method for inputting a text in a distributed system that comprises a secured device, or server, communicating with at least one electronic device, or terminal. The method makes it possible to prepare an image by associating certain values to areas defining said image. The image is projected to the user who can touch the areas of the images that he wants to select as he would do with the keys of keyboard. The finger movements are analysed and the position of the virtual keys selected by the user is transmitted to the server that establishes a correlation between these positions and the previously associated values.
