Description

PROCEDE DE TRACABILITE DES PRODUITS SANS AJOUT NI MODIFICATION DE LA MATIERE EN UTILISANT UNE SIGNATURE NUMERIQUE OBTENUE A PARTIR D'UNE OU PLUSIEURS CARACTERISTIQUES INTRINSEQUES DU PRODUITPROCESS FOR TRACEABILITY OF PRODUCTS WITHOUT ADDING OR MODIFYING THE MATERIAL USING A DIGITAL SIGNATURE OBTAINED FROM ONE OR MORE INTRINSIC CHARACTERISTICS OF THE PRODUCT
La présente invention concerne le domaine technique de la traçabilité des produits, et de la protection des marques.The present invention relates to the technical field of product traceability, and brand protection.
Il existe de nombreuses technologies développées pour protéger et tracer des produits.There are many technologies developed to protect and trace products.
Elles consistent pour l'essentiel à incorporer un signe aux produits, signe qui peut être visible ou dissimulé.They consist essentially of incorporating a sign to the products, a sign that can be visible or concealed.
Ces solutions répondent à des problématiques de logistiques, de gestion de flux et de stocks, pour lutter contre les ventes en marchés parallèles, pour lutter contre les ventes et les distributions de contrefaçons.These solutions address issues of logistics, flow management and inventory, to fight against sales in parallel markets, to fight against the sales and distribution of counterfeits.
Les solutions les plus simples consistent en une impression de chiffre, code barre , ou data matrice sur les différents emballages (primaire, secondaire). Les plus sophistiquées vont de l'intégration de micro puce RFID, aux gravures laser sur les parois intérieures du verre (dans le cas de flacons par exemple), en passant par l'intégration d'ADN artificiel, de nanotechnologies, etc.The simplest solutions consist of printing a number, barcode, or data matrix on the different packaging (primary, secondary). The most sophisticated ones range from the integration of micro RFID chips, to laser engravings on the inner walls of the glass (in the case of bottles for example), through the integration of artificial DNA, nanotechnologies, etc.
Toutefois, un inconvénient majeur des solutions de traçabilité ou d'authentification actuelles est qu'elles peuvent être détruites ou endommagées par les réseaux parallèles et contre facteurs. Ces réseaux sont capables d'investir fortement pour contrer les solutions de traçabilité actuelles. Toutes ont été détruites ou rendues illisibles en peu de temps.However, a major drawback of current traceability or authentication solutions is that they can be destroyed or damaged by parallel networks and against factors. These networks are able to invest heavily to counter current traceability solutions. All were destroyed or rendered illegible in a short time.
La demande FR2,870,376 propose un procédé pour l'authentification de supports fibreux, par exemple de type papier, basé sur la comparaison d'une signature numérique du produit fibreux testé avec une signature numérique générée à partir d'un support fibreux authentique. Dans ce procédé, il est fait appel à une signature numérique commune à tous les produits authentiques et non à une signature numérique unique de l'objet testé. Par ailleurs, les signatures effectivement décrites dans ce document sont des signatures obtenues à partir de caractéristiques microscopiques du produit.The application FR2,870,376 proposes a method for the authentication of fibrous supports, for example of the paper type, based on the comparison of a digital signature of the tested fibrous product with a digital signature generated from an authentic fibrous support. In this method, it uses a digital signature common to all authentic products and not to a unique digital signature of the object under test. Moreover, the signatures actually described in this document are signatures obtained from microscopic characteristics of the product.
Le brevet US5,673,338 et les articles de Wilkes et al. (Materials World, Institute ofUS Patent 5,673,338 and Wilkes et al. (Materials World, Institute of
Metals, London, 12, 1994) et de Buchanan et al. (Nature 436, 2005, p475) concernent également un procédé d'identification d'un objet basé sur l'utilisation d'une signature numérique obtenue à partir de caractéristiques microscopiques de cet objet. Ainsi, ces procédés prévoient l'acquisition d'une image microscopique d'une partie de l'objet, à un niveau de grossissement défini, et nécessitent un instrument de microscopie et des opérations de mise au point.Metals, London, 12, 1994) and Buchanan et al. (Nature 436, 2005, p475) also relate to a method of identifying an object based on the use of a digital signature obtained from microscopic characteristics of this object. So, these The methods provide for acquiring a microscopic image of a portion of the object at a defined magnification level and require a microscopy instrument and focus operations.
Il existe donc un besoin pour des procédés et techniques de traçage de produits manufacturés, qui soient fiables, facilement mis en œuvre, non dépendants de signes ajoutés et difficiles à détruire sans endommager les produits eux-mêmes. La présente invention permet de résoudre ce besoin.There is therefore a need for methods and techniques for tracing manufactured products which are reliable, easily implemented, not dependent on signs added and difficult to destroy without damaging the products themselves. The present invention solves this need.
La présente demande concerne en effet une nouvelle méthode pour assurer la traçabilité des produits manufacturés, tels que notamment des flacons ou emballages, qui repose en partie sur la détermination d'une signature numérique propre à chaque produit, à partir d'une ou plusieurs caractéristiques macroscopiques de celui-ci.The present application relates to a new method for ensuring the traceability of manufactured products, such as in particular vials or packaging, which is based in part on the determination of a digital signature specific to each product, from one or more characteristics. macroscopic of it.

Elle permet d'identifier de façon certaine un produit manufacturé.The present invention uses one or more macroscopic characteristics specific to each product to uniquely identify and trace it. It makes it possible to identify with certainty a manufactured product.
La présente invention a pour objet l'utilisation d'une signature numérique obtenue a partir d'au moins une caractéristique géométrique ou physique macroscopique intrinsèque d'un produit manufacturé, sans ajout de signe, ajout de matière ou de modification de la matière.The present invention relates to the use of a digital signature obtained from at least one intrinsic macroscopic geometric or physical characteristic of a manufactured product, without adding a sign, adding material or modifying the material.
Certains produits manufacturés ou artisanaux, en tout ou partie, présentent des formes complexes aléatoires, chaotiques, unique et stable, non copiable, non reproductible, difficilement altérable.Some manufactured or craft products, in whole or in part, have complex forms random, chaotic, unique and stable, non-copyable, non-reproducible, difficult to alter.
Les caractéristiques des produits manufacturés , en tout ou partie, peuvent être par exemple l'épaisseur des parois, les formes intérieures ou extérieures, la résistivité, ou toutes autres caractéristiques physiques macroscopiques à l'échelle du produit, qui sont notablement différentes.The characteristics of the manufactured products, in whole or in part, may be, for example, the thickness of the walls, the internal or external shapes, the resistivity, or any other macroscopic physical characteristics at the scale of the product, which are notably different.
Par exemple, il existe différentes façons de fabriquer des flacons ou emballages primaires de produits cosmétiques, aucune de ces façons n'est capable de produire des flacons ou emballages primaires rigoureusement identiques.For example, there are various ways of manufacturing vials or primary packages of cosmetics, none of these ways is able to produce vials or primary packages strictly identical.
Les flacons ou emballages primaires, de par leurs procédés de fabrication, sont tous différents. Ces différences sont parfois détectables à l'oeil nu.Bottles or primary packaging, by their manufacturing processes, are all different. These differences are sometimes detectable with the naked eye.
Ces flacons sont très largement utilisés dans l'industrie de la parfumerie et sont essentiellement en verre ou de composition verre et métal ou plastiques. De plus, les éléments matériels retenus auront une quasi invariance dans le temps.These flasks are very widely used in the perfume industry and are mainly made of glass or glass and metal or plastic composition. In addition, the material elements retained will have a quasi invariance in time.
Ainsi, plusieurs lectures de la signature numérique d'un même individu (produit manufacturé) donneront une signature numérique identique.Thus, several readings of the digital signature of the same individual (manufactured product) will give an identical digital signature.
La présente invention est complètement compatible avec les jus ou produits cosmétiques car aucun ajout n'est nécessaire et que les moyen d'acquisition ne sont pas destructif pour les jus ou produits cosmétiquesThe present invention is completely compatible with juices or cosmetic products because no addition is necessary and the means of acquisition are not destructive for juices or cosmetic products

La présente invention permet de générer un nombre a priori infini de signature unique.The present invention makes it possible to generate an a priori infinite number of unique signatures.
La présente invention s'intègre facilement dans les chaînes de production et de logistique sans les perturber. La présente invention permet d'installer des système d'acquisition déporter qui s'installe sans aucune modification des chaîne d'emballage.The present invention easily integrates into the production and logistics chains without disturbing them. The present invention makes it possible to install deporting acquisition systems which are installed without any modification of the packaging lines.

D'autres aspects et avantages de l'invention apparaîtront à la lecture de la description suivante de modes de réalisation, en références aux figures annexées dans lesquelles: les figures FIG 1 , FIG 2 et FIG 4 représentent des images de produits manufacturés issus de l'industrie du parfum, prises directement et traitées avec différents filtres. La figure FIG 4 fournit un exemple de la différence de l'angle entre les contours intérieurs synchronisée de deux différents flacons ; la figure FIG 3 reprend les étapes suivants un procédé selon la présente invention.Other aspects and advantages of the invention will appear on reading the following description of embodiments, with reference to the appended figures in which: FIGS. 1, 2 and 4 show images of manufactured products from the perfume industry taken directly and treated with different filters.

Le procédé décrit sur la FIG 3 se décompose classiquement en phases comme suit :The process described in FIG. 3 is classically decomposed into phases as follows:
1. Pour chaque type de produit manufacturé et pour chaque caractéristique retenue, une méthodologie et une zone d'acquisition sont définies.1. For each type of manufactured product and for each characteristic selected, a methodology and an acquisition area are defined.
Les Critères de choix sont multiples, tels que les caractéristiques retenues, les facilités d'acquisition et d'analyses, les perturbations, etc. Lorsqu'il s'agit de produit industriel, la configuration des chaînes de conditionnement peut être déterminante pour le choix de la zone d'acquisition. Toute les zones ne sont pas toujours facilement visibles sur les chaînes.The selection criteria are multiple, such as the characteristics retained, the acquisition and analysis facilities, the disturbances, etc. In the case of industrial products, the configuration of the packaging chains can be decisive for the choice of the acquisition zone. Not all areas are easily visible on channels.
2. Une phase de détection et d'acquisition d'au mois une caractéristique est réalisée, afin de générer au moins une signature numérique. Cette caractéristique peut être acquise de plusieurs façons, comme par exemple :2. A detection and acquisition phase of at least one characteristic is performed, in order to generate at least one digital signature. This characteristic can be acquired in several ways, for example:
-une prise optique directe des contours des surfaces intérieures ou extérieures des produits manufacturés ;a direct optical outlet of the contours of the interior or exterior surfaces of the manufactured products;
-une prise optique en plaçant par exemple une cible derrière le flacon et en récupérant le signal déformé à travers le produit manufacturé ;an optical socket, for example by placing a target behind the bottle and recovering the deformed signal through the manufactured product;
-une émission sonore et en récupérant la réponse ;-a sound emission and retrieving the answer;
-des systèmes laser permettant de mesurer l'épaisseur des parois propres à chaque produit manufacturé ;laser systems for measuring the thickness of the walls specific to each manufactured product;
-des rayons X ; et/ouX-rays; and or
-toute autre mesure physique liée aux caractéristiques du produit manufacturé.-any other physical measure related to the characteristics of the manufactured product.
3. Le traitement des « images » brutes afin d'en extraire au moins une signature numérique. Ce traitement peut se faire par différentes méthodes connues et classiques de l'analyse et des traitements du signal, de l'optique, de l'électronique ou de tout autre type. Tous les types de filtres numériques ou analogiques sont utilisables. Pour exemple et d'une façon non exhaustive, nous citerons.3. Processing raw "images" to extract at least one digital signature. This processing can be done by various known and conventional methods of analysis and processing of the signal, optics, electronics or any other type. All types of digital or analog filters are usable. For example and in a non-exhaustive way, we will quote.

L'analyse et l'extraction de données doivent être de préférence suffisamment fiables et ou redondantes pour que l'altération d'une partie du produit manufacturé, ou de la zone d'acquisition, permette quand même la génération de la signature numérique.Transformed known as wavelets. The analysis and the extraction of data must preferably be sufficiently reliable and redundant so that the alteration of a part of the manufactured product, or the area of acquisition, still allows the generation of the digital signature.

De plus, la présente invention évite ou réduit le risque lié à la destruction de la signature numérique. En effet, l'altération d'une partie du produit n'empêche pas la génération de signature(s) unique(s) suffisante(s) à son identification de façon certaine.A portable version may allow in situ reading of products The present invention has many advantages over prior art. Thus, the principle of using one or more random or stochastic macroscopic characteristics is very interesting because it is freed from the principle "What man did, man can undo or redo" which is the heel of Achilles from most current solutions. In addition, the present invention avoids or reduces the risk of destroying the digital signature. Indeed, the alteration of a part of the product does not prevent the generation of unique signature (s) sufficient (s) to its identification certainly.
Un autre aspect de la présente invention est constitué par la protection d'information. L'utilisation de(s) caractéristiques intrinsèques par des traitements numériques afin d'obtenir une (des) signature numérique rends les informations non directement accessibles ni traduisibles. Il faut en effet connaître la caractéristique retenue et le traitement permettant de générer la signature.Another aspect of the present invention is the protection of information. The use of intrinsic characteristics by digital processing to obtain a digital signature makes the information not directly accessible or translatable. It is indeed necessary to know the selected characteristic and the treatment allowing to generate the signature.
Néanmoins si pour l'utilisation il semble nécessaire de la rendre accessible, l'information générée par la présente invention peut être liée au produit et / ou aux emballages, soit en répétant la signature numérique générée par la présente invention soit par une signature autre qui est alors corréler au niveau de la base de données. Le système d'acquisition de la présente invention se trouvera alors le plus proche possible de la mise dans l'emballage secondaire, lorsqu'il est lui-même tracé, permettant ainsi une corrélation entre la(s) signature numérique du primaire et du secondaire au sein de la base de donnée. Les figures FIG 1 , FIG 2 et FIG 4 représentent un exemple de signatures numériques obtenues à partir de caractéristiques macroscopiques de produits utilisés dans l'industrie du parfum : Dans cet exemple, les images sont prises directement et traitées avec différents filtres. Il s'agit la du début de l'étape 3 qui permet de générer une signature numérique La présente invention est particulièrement adaptée au cas des flacons, notamment de parfum. Les procédés de fabrication leur donnent des formes internes facilement exploitables au sens de la présente invention. Les recherches esthétiques qui guident la création de ces flacons conduisent leur forme vers une complexification croissante, ce qui est favorable au procédé de la présente invention. Cela peut être par exemple une face d'un produit manufacturé, le « cul » de flacon ou une zone sur une des faces. However, if for the use it seems necessary to make it accessible, the information generated by the present invention may be linked to the product and / or the packaging, either by repeating the digital signature generated by the present invention or by another signature which is then correlate at the database level. The acquisition system of the present invention will then be as close as possible to the packaging in the secondary packaging, when it is itself drawn, thus allowing a correlation between the digital signature (s) of the primary and secondary within the database. FIGS. 1, 2 and 4 show an example of digital signatures obtained from macroscopic characteristics of products used in the perfume industry: In this example, the images are taken directly and processed with different filters. This is the beginning of step 3 which makes it possible to generate a digital signature. The present invention is particularly adapted to the case of flasks, in particular perfume bottles. The manufacturing processes give them easily exploitable internal forms within the meaning of the present invention. The aesthetic research that guides the creation of these bottles lead their shape towards increasing complexity, which is favorable to the process of the present invention. This can be for example a face of a manufactured product, the "bottom" of a bottle or an area on one of the faces.
