Description

System and method for traceability and authentication of a product

TECHNICAL FIELD OF THE INVENTION

The present invention relates to the field of traceability and authentication systems of a product, more particularly, on which is affixed an identification and authentication device. The present invention also relates to a method of traceability and authentication of at least one product on which is affixed an identification and authentication device.

BACKGROUND OF THE INVENTION

A problem in the field of product traceability and authentication systems concerns the reliability of the system, in all domains.

Indeed, most manufactured products have a marking to ensure their traceability and identification, for example when packaging the product at the manufacturer or transmitter, when the product is shipped by the manufacturer, at each step of the delivery of the product by one or more conveyor (s) or intermediate (s), and when receiving the product by a destination or a receiver. In order to guard against the loss, theft or the realization of counterfeits of the product; it is necessary, on the one hand, to trace the delivery of a product, and on the other hand, to identify and authenticate the product upon receipt of the product by the recipient.

It is known from the prior art that most manufactured products have a unique identifier, coded and difficult to reproduce. There are in the prior art various coding and product identifier systems known to those skilled in the art. Two-dimensional codes include frequently used. These are generally in the form of a matrix composed of dark squares and white or translucent squares, whose relative position makes it possible to encode a specific string of characters on the product. The string can be a keyword, or a concatenation of different keywords, that refer to data included in a database. In this family of two-dimensional coding system, the "QR Code" is one of the most widespread. It is usually small in order to be discreet about the product, and to complicate the illegal reproduction of the product identifier. The QR Code is used in particular to store digital information (texts, website addresses, etc.) and can be decrypted from a mobile phone equipped with a camera and appropriate decoding software.

This solution of the prior art has the disadvantage of using a single identifier encrypted by a two-dimensional code for both the traceability and authentication of a manufactured product. Indeed, the encrypted information for the traceability of the product is the same as for the product authentication. Thus, once the encrypted identifier has been decrypted by a device comprising appropriate software, it is easy to copy the original identifier and create a falsified identifier containing the same encrypted information and, for example, use it on a other product. The falsified identifier contains the same information as the original encrypted identifier, which makes possible a false identification and an authentication of a product of different origin, when the recipient receives the product. It will also be difficult to know at what point in the delivery stage, the product has been changed and falsified. This traceability and authentication system using a unique encrypted identifier to track and authenticate a product is easily falsifiable and is therefore not reliable in use.

He also known from the prior art a system and a method for authenticating a drug product with a mobile computing device, as for example described in US Pat. No. 8,534,543. This system, intended to protect a medicine against counterfeiting, comprises a inactive ingredient in the product for creating a first encrypted identifier on a surface of the product and including information to distinguish only the product from another similar or different product; a second identifier is applied on the surface of the product, so as not to mask the first identifier and the second identifier is encrypted to authenticate the product and its manufacturer.

The disadvantage of the system described in the document of the prior art above, is that it does not allow to trace the product during its transit from the manufacturer to the recipient. Indeed, the two identifiers contained in the system of the previous document only allow to authenticate the product with respect to another product and the manufacturer of the product. In addition, unlike the first identifier disposed in the product, the second identifier of the system, which is arranged on the product, is easy to access for a counterfeiter that can decrypt and copy and / or falsify this second identifier, or both identifiers. To overcome this drawback, this system provides an introduction of the first identifier in the product, which limits the scope to products comprising a transparent package so that the first identifier is visible to authenticate the product. This feature also has the disadvantage that the customer or receiver may err in the order of tag scanning and trigger an inappropriate system error.

In this context, it is interesting to propose a solution to overcome the disadvantages of the prior art by facilitating and improving the traceability and authentication system of a product.

FIG. 1 represents a diagram according to an embodiment of a system for traceability and authentication of a product on which an identification and authentication marking is used, the system further comprising a reading device and registration and an information system;

FIG. 2 represents a perspective view of an embodiment of the identification and authentication marking comprising a first encrypted identifier and a second encrypted identifier, before the first identifier is affixed to the second identifier;

- Figure 3 shows a diagram showing an embodiment of a method of traceability and authentication of a product on which is used identification marking and authentication. DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

The invention, with reference to Figures 1 to 3, will now be described.

The present invention relates to a system for traceability and authentication of at least one product (1) on which at least one marking (2) of identification and authentication is used.

In certain embodiments, for example as shown in FIGS. 1 and 2, the identification and authentication marking (2) of the traceability and authentication system of the product (1) comprises, on the one hand, a first encrypted identifier (31) comprising at least a series of basic information about the product and / or its provider and / or recipient, and secondly a second encrypted identifier (32) comprising a series of confidential information . Thus, the marking consists of a dual identifier including encrypted information to facilitate and secure the identification, authentication and traceability of a product issued by a supplier and received by a recipient. The first encrypted identifier includes basic product information (e.g., order number, product type, etc.), and / or the supplier (e.g., such as name, physical address and / or web, the number of the supplier) and / or the addressee (eg such as the name, address of the recipient) so that the product is well distributed by one or more intermediaries or conveyors; while the second identifier includes confidential information so as to authenticate the product in a secure and reliable manner. In this embodiment, the second identifier (32) also includes information relating to the integrity of the product (1), encrypted. Indeed, the encrypted information on the integrity of the product can distinguish without confusion, for example an original and legitimate product of a counterfeit. In this embodiment, for example as shown in FIG. 2, the second encrypted identifier (32) is affixed under the first identifier (31) encrypted so as to be masked by the first identifier (31). Thus, it will be difficult to falsify the second encrypted identifier masked by the first encrypted identifier. The first encrypted identifier (31) is destroyed to allow access to the second encrypted identifier (32). This is a reliable way to secure and enhance access to confidential information held by the first identifier.

In some embodiments, the system for traceability and authentication of at least one product (1) on which at least one identification and authentication marking (2) is used also comprises at least one system for information (4). This information system makes it possible, on the one hand, to generate identification and identification marking identifiers, and on the other hand, to trace the distribution path of the product and to deny integrity or not. marking and therefore the product on which the marking is affixed.

Indeed, in one embodiment, the link between the two encrypted identifiers is only known in the information system, and on the other hand each reading and communication or processing device is recorded with its identifier and its location on the information system, so that the distribution path and product validation are stored in the information system. In some embodiments, the system further comprises at least one device (5) for reading and communicating and processing the encrypted information contained in the identifiers (3, 31, 32) of the identification marking (2) and 'authentication. The apparatus makes it possible to decrypt and / or process, from for example and without limitation a camera and appropriate decryption software, the encrypted information contained in the identifiers of the marking. Then, the device communicates this information or the result of the treatment to the information system and vice versa, the information system is able to communicate with the device (5), for example to identify and / or authenticate the product. For example, as shown in FIG. the apparatus (5) processes (53) the information of the identifiers (3, 31, 32) and the apparatus (5) communicates (54) this processed information to the information system (4) for storage.

In certain embodiments, for example as shown in FIG. 2, the identification and authentication marking (2) comprises a first layer (21) comprising the second encrypted identifier (32) and a second layer (22) comprising the first identifier (31) encrypted and covering the second identifier (32). The marking is composed of double layers each intended to receive an encrypted identifier, so as to distinctively separate the information from the identifiers and simplify the achievement of identification and authentication marking.

In some embodiments, data for operational management (recipient address, handling precautions, etc.) and / or marketing data (URL of the brand website, loyalty program, etc.) are incorporated. in the first identifier (31). This data is basic information to distribute and identify the product at each stage of delivery of the product until the receipt of the product by the recipient.

In some embodiments, the encrypted information relating to the integrity of the product (1) contained in the second identifier (32) includes confidential information on the physical and / or technological characteristics of the product, or confidential information that only the recipient or supplier can consult on the information system (4) so as to ensure authenticity of the product (1), the connection between these two encrypted information is, in one embodiment, only known in the information system ( 4). The confidential data contained in the second identifier, are encrypted and masked by the first identifier, which secures access and falsification of these data. In this embodiment, only those confidential product integrity data that are known to the system information, make it possible to invalidate or not the authenticity of the product when the product is received by the recipient.

In some embodiments, the first (31) and second (32) encrypted identifiers are in the form of two-dimensional codes. The identifiers are encrypted, i.e. the identifiers include a computer protection system to ensure the integrity and inviolability of the data during transmission or storage. A two-dimensional code is used in one embodiment to store more information than a conventional bar code and the data is directly recognized by the reading and recording or communication apparatus.

In some embodiments, for example as shown in Figure 2, the two-dimensional codes are QR codes. QR Codes can be created and used easily and quickly. Indeed, the QR Code can be read easily with a reading device, for example such as a scanner or a mobile phone equipped with a QR code reading application.

In some embodiments, the identification (2) and authentication marking is performed on a sticker (2) sticker or a sticker (2). The self-adhesive sticker is an easy-to-use support with an adhesive layer that allows you to affix the sticker easily and directly on any type of surface. Similarly, the sticker allows you to print identifiers in all types of formats, easy installation, good resistance to delamination and to communicate at low cost.

In other embodiments, the identification (2) and authentication marking is achieved by affixing one or more layers of paint or ink to the product, constituting each support layer of the markings, with the aim of the second layer on which is printed the first information, the peculiarity of being able to scratch this second layer without destroying the first layer, nor the second information printed on the first layer.

In some embodiments, the first encrypted identifier (31) is destroyed by peeling off or scratching it. In some embodiments, when the first encrypted identifier (31) is destroyed, for example by taking off, a message appears in a frame of the layer (22) destroyed to invalidate its use. Indeed, the first identifier is manually destroyed by taking off or scratching the second layer of the marking so as to access the confidential information contained in the second identifier. In some embodiments, the transmitting entity defines and informs whether the second identifier (32) encrypted must be destroyed during the destruction step, for example and in a non-limiting manner to the receipt of the product (1). Thus, the second encrypted identifier (32) is destroyed by taking off or scratching at the destruction step which is a decisive step in the life of the product (1) enabling the authentication of the product (1).

In some embodiments, the reading and communication or processing apparatus (5) is a scanner (5) or a mobile device (5) comprising

- or appropriate decryption software for decrypting the encrypted information contained in the identifiers (3, 31,

32) of the marking (2) and having received, before or after reading the first information, the connection between the two encrypted information to verify and authenticity,

or means of communication for sending the encrypted information to the information system which alone knows in this case, the connection between the two encrypted information; either send to the information system a signal attesting to the authenticity and in this case, the reading device and communication or processing is the only one to know the connection between the two encrypted information. Indeed, in one embodiment, the apparatus (5) comprises a reading software for reading the encrypted information contained in the identifiers (3, 31, 32) and communicating with the identifier of the apparatus (5). and the location data of the apparatus (5) to the information system (4). Thus, the reading device (5) is able to transmit the reading of a first encrypted information contained in the first identifier (31) and a second encrypted information contained in the second identifier (32) to the system of information (4). The information system, knowing the information of the two identifiers (31, 32) and the connection between these two identifiers (31, 32), is able to check the information transmitted by the device (5) to attest to the authenticity identifiers (31, 32) and therefore the product (1), as well as ensuring the traceability of the delivery.

In another embodiment, the reading and communication or processing apparatus (5) is a scanner (5) or a mobile device (5) comprising appropriate decryption software for decrypting the encrypted information contained in the identifiers. (3, 31, 32) of the marking (2) and having received, before or after reading the first information, the information defining the connection between the two encrypted information to verify this connection and attest to the authenticity, The apparatus (5), knowing the information and the link between the information contained in the identifiers (31, 32), is able to send the authentication signal of the product (1) to the information system, with its identifiers and its location, thus confirming the receipt of the product (1) by the recipient or the passage of the product by an intermediary and thus ensuring traceability.

The present invention also relates to a method of traceability and authentication of at least one product (1) on which at least one marking (2) of identification and authentication is used. In certain embodiments, as represented for example and not by way of limitation in FIG. 3, the method comprises the following successive steps:

a step of writing encrypted information (E1, E1 1, E12) at least in a first (31) and a second (32) identifier by an information system (4),

a printing step (E2a) of the second identifier (32) encrypted on the identification and authentication marking (2),

an affixing step (E2b) of the second identifier (32) encrypted on a surface of the product (1),

a print step (E3a) of the first encrypted identifier (31),

a step of affixing (E3b) a layer (22) containing or supporting the first identifier (31) encrypted on the second identifier (32) encrypted with the same marking (2) so as to mask the second identifier (32) ,

at least one reading and communication step (E4) of the first identifier (31) encrypted by an apparatus (5) for reading and communication or processing identified in an information system (4) with its location, the apparatus (5) reading and communication or processing sending at least the result of reading and the identifier of the apparatus (5) to thereby provide information on the transit of the product (1) to the information system (4) ,

- A destruction step (E5) by a manual action of the first identifier (31) encrypted product (1) so as to access the second identifier (32) encrypted on receipt of the product (1) by a recipient,

a step of reading (E6) the encrypted information contained in the second identifier (32) by a device (5) for reading and communicating or following processing: o either sending the encrypted information to the information system (4) so that it certifies the authenticity, o is the treatment by the appropriate means of the reading device (5) which in this case informs the system information (4) of the authentication or not of the product (1).

The traceability and authentication process has the advantage of making reliable the tracking and authentication of at least one product on which is affixed at least one identification and authentication marking. Indeed, the use of the marking makes it possible to secure and protect the product against any falsification of the data and to monitor the distribution of the product as well as its authentication when it is delivered to the recipient. In one embodiment only the information system knows the information and the link between the information contained in the identifiers of the marking to attest to the authenticity of the marking and therefore of the product.

In some embodiments, a storage of the first encrypted identifier (31) is activated in the information system (4) by a device (5) for reading and communicating the product sending entity (1) after the apposition step (E2b) of the first identifier (31) on the second identifier (32).

In some embodiments, the method also comprises one or more reading step (E4), by at least one device (5) previously identified and located in the information stored by the information system (4) and associated with an intermediate intervening during the transit of the product (1), the first identifier (31) encrypted before the reading step and a reading and recording step (E6) of the second identifier (32) encrypted by a reading device (4) and communication or processing (the same or not in the case of multiple intermediaries), when delivering the product to the recipient. In some embodiments, the information system (4) first stores in its memory a series of encrypted information contained in the first identifier (31), when the identification marking (2) is affixed. and authentication on the product (1) by an issuing entity, in association with the second identifier (32) and the relationship between the first (31) and the second (32) identifier to attest to their authenticity and in a second time for the traceability of the product (1) the identifiers and location data of the devices involved in the delivery process, at each communication by a reading and communication device (5) during the transit of the product (1) by at least one intermediary and finally during the delivery records, either the authenticity established by the reading and communication apparatus (5), or the information transmitted concerning the second identifier (32) and erases the authenticity, making sure that the relationship memorized initially between the first (31) and the second (32) identifier is still respected.

In some embodiments, at each stage of delivery, the intermediary carrying or handling the product (1) scans the identification and authentication marking (2) with an identified reading and communication device (5) and previously located by the information system (4); and the information of the first identifier (31) is transmitted to be registered in a traceability tracking system (for example and not limited by EPCIS monitoring), in order to follow the entire life cycle of the product; the traceability system is managed by the information system (4). This embodiment makes it possible to know each participant transporting and distributing the product at any time, so as to detect any anomaly, for example a loss or theft of the product, which may occur during the distribution of the product. Similarly, this embodiment makes it possible to obtain a history of the last owners of the product and / or a geolocation of the product so as to detect and ensure a prevention, for example when a fraud is suspected. In some embodiments, the encrypted second identifier (32) is destroyed by peeling or scraping upon receipt of the product (1). Indeed, during the delivery of the product to the recipient, the intermediary of the product will scan the first identifiers (31) with a device (5) for reading and communication or processing, then destroy the first identifier (31) taking off or by scraping to scan the second identifier (32) so that the information system (4) invalidates or not the integrity of the marking (2) identification and authentication.

The system and the method of traceability and authentication of at least one product on which at least one identification and authentication marking is affixed, are applicable to different domains, such as for example and in a non-limiting way the tracking and authentication of spare parts, return guarantee management or after-sales service, products in the field of luxury, management of seals, authentication of works of art or wines and spirits.
