(FR) ELÉMENT, DISPOSITIF ET PROCÉDÉ DE MARQUAGE DE PRODUIT
Abstract: front page image
(EN) The invention relates to a method and device for the ultrasonic identification and/or authentication of an object to be identified and/or authenticated, including a marking element including a substrate in which impurities are distributed, wherein ultrasonic waves are absorbed by said impurities, and move within said impurities at speeds that are different than those at which the ultrasonic waves move within the substrate, the distribution of the impurities in said element being detectable by the ultrasonic reading device and used for identifying and/or authenticating said object.
(FR) Procédé et dispositif d'identification et/ou d'authentification par ultrasons d'un objet à identifier et/ou authentifier, comprenant un élément de marquage comprenant un substrat dans lequel sont réparties des impuretés dans lesquelles des ondes ultrasonores sont absorbées et se déplacent à des vitesses différentes des vitesses auxquelles elles se déplacent dans le substrat, la répartition des impuretés dans ledit élément pouvant être détectée par le dispositif de lecture à ultrasons et permettant l'identification et/ou l'authentification dudit objet.
