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

The invention is a method for authenticating a device which comprises a chip and a body carrying the chip. The body comprises a graphical security feature. The method comprises the steps of: The extracting step and the authenticating step are carried out by a machine distinct from the device.

Method of authenticating a device

A method and associated device for checking a biometric signature by a simple and secure calculation adapted to personal objects of the chip card type. The method is based on the storage within the object of an obscured biometric signature and an associated authentication code. A terminal capturing a fingerprint compares the fingerprint data with the obscured biometric signature transmitted by the card and transfers the result of this comparison to the chip card, which validates this result with the authentication code.
