The invention concerns a method for reading single volume and non-reproducible identification means (100) comprising a mixture of at least two materials (110 and 120) distinguishable from each other (110 and 120), characterised in that it consists in recognising in two dimensions the internal heterogeneous structure of said identification means (100) and in isolating and demonstrating its third dimension thereby eliminating the risk of imposture. Said characteristic enables to reduce storage volume and the periods of time required for scanning, acquisition and comparison operations performed in such processes. The invention also concerns a device for implementing said method. The invention is useful for identifying and authenticating objects, living beings, transactions.
La présente invention concerne un procédé de lecture d'un moyen d'identification (100) volumique unique et non reproductible (100) du type de celui comprenant un mélange d'au moins deux matériaux (110 et 120) distinguables l'un de l'autre (110 et 120), remarquable en ce qu'il consiste d'une part à reconnaître la structure hétérogène interne en deux dimensions dudit moyen d'identification (100) et d'autre part à mettre en évidence et à prouver sa troisième dimension, ce qui rend un leurre impossible. Cette caractéristique permet de diminuer le volume de stockage ainsi que la durée nécessaires aux opérations de lecture, d'acquisition et de comparaison classiquement réalisées dans de tels procédés. L'invention concerne également un dispositif permettant de mettre en oeuvre ledit procédé ainsi qu'un moyen d'identification adapté audit procédé. Applications: identification et authentification d'objets d'êtres vivants, de transactions.
