摘要： The invention relates to a device for reading a message which comprises: a means for reading biometric data of a holder of the medium; a means for capturing, on a medium, an encoded message comprising elementary message units, said message having noise that consists of marking defects of the message on said medium which are random and unpredictable for each elementary message unit; a means for reducing the noise of the captured message, based on biometric data; and a means for decoding at least one portion of the message in which the noise has been at least partially removed. In certain embodiments, the decoding means uses redundancies of the message with the noise removed to determine at least one portion of the encoded message.

摘要： The method for marking materials comprises: a step (210) for generation of a code, a step (215) for random selection of at least one zone of said material and a step (220) for marking the surface or the core of each zone of the material with a laser beam to represent the code thereon in a manner imperceptible to the naked eye. The random selection step of at least one zone of the material is preferably carried out for each piece of material to be marked. During the step of generation of a code, a two-dimensional barcode is preferably generated and during the marking step, the barcode is represented in two dimensions. According to some embodiments, the method further comprises a step of marking the material in a manner visible to the naked eye, a random selection is made of at least one part of a mark visible to the naked eye and/or said visible mark comprises information relating to the position of at least one zone in which the code imperceptible to the naked eye is represented.

摘要： The method for identifying documents comprises: a step of marking the document with an anti-copy mark that is identical for a plurality of documents; a step of reading an anti-copy mark; a step of generating an identification mark varying from document to document based on the reading of the anti-copy mark; and a step of marking said document to form said identification mark on said document. As embodied, the method also comprises a step of printing a uniform area, and the step of marking the document to form the identification mark comprises a step of emitting light with a laser into the uniform area. As embodied, the method also comprises a step of invisibly marking the identification mark on said document.
