The invention relates to a method for authenticating a secure document comprising data printed by analogue or digital printing, said method comprising the following operations: &#x2014;definition, from among a set of graphical and/or alphanumeric data of the secure document, of at least one distinct data area including at least one distinctive pattern; &#x2014;during an operation of fabrication of the secure document, reading the distinct data area onto a storage device so as to form a distinct reference data area; &#x2014;in the course of an operation of verification of the authenticity of the secure document, extracting the distinct data area from a digitized version of the secure document; and&#x2014;comparing the extracted distinct data area with the distinct reference data area so as to determine a level of matching between said distinct data areas and to deduce therefrom a positive authentication or negative authentication.

Method for authenticating a secure document

Generation of one dimensional guilloche patterns able to be affixed on a document, each guilloche pattern being able to encode variable alphanumeric data providing a different appearance to each guilloche pattern, by formatting alphanumeric data to be encoded in the form of a predefined number of data blocks with a predefined size, generating a carrier function having a plurality of parameters, the formatted data blocks forming at least one of the parameters, and modulating the carrier function by the formatted data blocks so as to encode the alphanumeric data graphically, each data block defining a guilloche pattern, the number of data blocks defining the number of guilloche patterns, the carrier function associated with a formatted data block is modulated locally, each datum of the block being encoded locally in the guilloche pattern, by interpolation of a predefined point associated with the carrier function.

Method for generating variable guilloche patterns, implementing device and identification document comprising such patterns

A method of inserting guilloche patterns in a document, each guilloche pattern being capable of encoding variable alphanumeric data ensuring a different aspect at each guilloche pattern so as to render said document secure using an operation of determining an insertion intensity of each guilloche pattern previously generated on the basis of a mid-gray level of the document near said guilloche pattern. A device for implementing this insertion method. The method further provides for extracting guilloche patterns from a secure document likely to be degraded by determining a contrast card of at least one portion of the secure document that includes the guilloche patterns, identifying, on this contrast card an optimal percolation trajectory, and extracting the optimal percolation trajectory, said trajectory corresponding to the guilloche pattern. The method further provides for authentication of the guilloche patterns of a secure document likely to be degraded, by the extraction operations, and comparing each extracted guilloche pattern with a corresponding theoretical guilloche pattern.

Method for the insertion of guilloche patterns, method for the extraction of guilloche patterns, method for the authentication of these guilloche patterns and devices for implementation

To place an insert cut out of film with no gaps in a cavity formed in a foil, after placing the foil on a supporting substrate, the cavity is punched into the foil by means of a tubular cutting punch comprising an inner pusher with a cutting edge in the required shaped of the cavity and the insert, so that the edge goes through the thickness of the foil and cuts a slug out of it; the punch is lifted with the slug held inside the punch, without moving the foil, the film is brought between the foil and the edge of the punch, the punch is lowered once again so as to cut the insert out of the film and then push the insert cut in that way in the cavity with a pusher, and the punch and the pusher are removed, with the insert held in place in the cavity.
