Title (EN) METHOD FOR MARKING AND AUTHENTICATING AN OBJECT
(FR) PROCEDE DE MARQUAGE ET D'AUTHENTIFICATION D'UN OBJET
Abstract:
(EN) The invention concerns a method for marking (A, B) and authenticating (C) an object (10) comprising the combination of two different data (K, N) mutually linked by means of a given arbitrary correspondence and used for authenticating the object, at least one of the two data (K) being intrinsically undetectable by an observer, the scanning of the two data and the verification of their mutual correspondence being performed during authentication of the object. The method is characterised in that the two data are non-random and said undetectable information is materialized by means interacting with the structure of the object.
(FR) L'invention concerne un procédé de marquage (A, B) et d'authentification (C) d'un objet (10) comportant l'association à l'objet de deux informations différentes (K, N) liées entre elles par une correspondance arbitraire données et utilisées pour l'authentification de l'objet, au moins une des deux informations (K) étant intrinsèquement imperceptible par un observateur, la lecture des deux informations et la vérificaiton de leur correspondance entre elles étant réalisées lors de l'authentification de l'objet, procédé caractérisé en ce que les deux informations sont non aléatoires et ladite information imperceptible est matérialisée par des moyens interagissant avec la structure de l'objet.
