Irrespective of which codings 12 and 18 are used, it can be seen that the first information and the second information can be obtained by the detection device 50 in conjunction with the associated decoding device 51 . This is preferably done immediately after the product 10 has been manufactured or packaged, for example by the manufacturer.

Otherwise, at a later point in time, a counterfeit product could be brought into circulation, which, for example, has different codings or does not have one or both of these codings at all, and at the same time the stored information, which corresponds to the original codings, could also be manipulated in order to do so it again matches the counterfeit product.

Only when this transmitted data matches the data stored in memory 120 is it the originally packaged original product. A corresponding notification can be transmitted from the server 102 to the querying data processing device.

Abstract

L'invention concerne des procédés de suivi et de contrôle de produits (10) de haute qualité ou sensibles. Selon un premier procédé, le produit (10) est enregistré de manière sûre par le fait que deux codages différents (12, 18), qui sont appliqués sur un emballage ou un scellement du produit (10), sont détectés et les informations codées sont stockées de manière sécurisée. Ce procédé est de préférence effectué dans un système réparti en utilisant par exemple une chaîne de blocs. Un nouveau contrôle du produit (10) peut être effectué à chaque autre endroit de la chaîne de distribution, les informations pouvant être à nouveau détectées étant également mémorisées en tant que partie de la chaîne de blocs. De cette manière, l'authenticité du produit peut être contrôlée en tout point de la chaîne, en particulier lors de la remise finale du produit (10), et toute manipulation en un emplacement déterminé dans la chaîne peut être déterminée.
