Definitions

  • This invention relates to a system and method for authenticating a product.
  • Counterfeit goods are a major threat to both producers and consumers alike. From a customer's perspective, the counterfeit goods may present a material risk to their health and safety. From a producer's perspective, the counterfeit goods may present a significant risk to their financial security and reputation. Accordingly, there is interest from both the producers and the consumers to tackle the dissemination of counterfeit goods.
  • counterfeiters target high value goods in industries such as, but not limited to, pharmaceuticals, aviation/automotive parts, luxury goods and medical devices. It is immediately apparent how counterfeit goods that are not manufactured to the required exacting specifications in the pharmaceutical, aviation/automotive parts and medical devices fields could have catastrophic consequences for the consumer. It is also evident how counterfeit goods may have a damaging affect on the reputation of genuine producers when products thought to originate from them are found to be deficient.

  • the product manufacturing facility 7 sends a product record to the blockchain database.
  • the blockchain database saves the product record and the associated QR code 19 in the blockchain database.
  • the APP will verify a digital signature retrieved from the QR code against its own internal database on the UCD. Failure of this secondary verification will return a counterfeit message on the user interface of the UCD.

  • the blockchain database receives and reviews the QR code and determines if there is a product record in the blockchain database that corresponds to the QR code. If there is a product record in memory that corresponds to the scanned QR code, the blockchain database returns the product record to the UCD.
  • the user of the UCD then inspects the product record on the user interface of the UCD and compares the product record with the physical product, thereby verifying the authenticity of the product.

  • QR code there may be a limit on the number of times a QR code may be authenticated. For example, if the QR code is authenticated more than 5 times, it is deemed that the QR code in question has been copied and is being used on multiple goods and the QR code can be marked in memory as fraudulent. In those cases (where the QR code is deemed fraudulent) a message is returned to the UCD indicating that the product is fraudulent. It will be understood that other additional functionality may be added to the system and method without departing from the scope of the present invention. For example, the system and method may also be used to warn a customer that the product is past its "best before" and/or "use-by" date.
  • the product has passed its use-by date, its efficacy may be reduced or indeed it may represent a danger to the consumer. If the consumer scans a QR code on the product, a suitable warning message may be presented to them on the user interface of the UCD. Similarly, if the product was part of a product recall, the information in the database may be updated with that information so that if the customer scans a code on a product that has been recalled, the customer will be warned that the product is part of the recall and should not be used/consumed. The message may also provide details of where the product is to be returned.

Abstract

La présente invention porte sur un procédé et un système d'authentification d'un produit. Le système peut comprendre une base de données de chaîne de blocs ayant un générateur de code QR ; une installation de fabrication de produit ayant une imprimante de code QR ; un canal de communication sécurisé entre la base de données de chaîne de blocs et l'installation de fabrication de produit ; un dispositif de communication d'utilisateur (UCD) ayant une interface utilisateur, une application de vérification (APP) et une caméra ; et un canal de communication entre l'UCD et la base de données de chaîne de blocs. Lors de l'utilisation, l'installation de fabrication demande un code QR en provenance de la base de données de chaîne de blocs. Lors de la réception dudit code QR, l'installation de fabrication marque un produit avec le code QR et envoie un enregistrement de produit relatif au produit et associé audit code QR à la base de données de chaîne de blocs pour le stockage. Un consommateur avec un téléphone intelligent ou un dispositif similaire peut capturer le code QR et extraire un enregistrement de produit de telle sorte que l'enregistrement de produit peut être comparé au produit physique pour vérifier l'authenticité.
