SYSTEM AND METHOD FOR DYNAMIC AUTHENTICATION OF PRODUCTS USING BLOCKCHAIN TECHNOLOGY

Resumen de: EP4700667A1

The invention is developed in the field of technology. The invention relates to a system for dynamically authenticating alcoholic beverages, including digital cryptographic mechanisms that allow real-time access to the status of an alcoholic beverage, through the use of blockchain technology. In particular, the system consists of a "quick-response" (QR) code provided on the inside of the lid (liner) or cap or cork or dispenser or device used to close the product and the QR code is only displayed when the product is open, to then be authenticated by the user when they wish to verify the legitimacy and traceability of the product. A cryptoasset (not cryptocurrency) is linked to each QR code, which is backed by the blockchain, and, by reading the unique QR code printed on each cap, the metadata thereof is obtained via the web. Only the first status of the bottle "BOTTLE SAFE FOR CONSUMPTION" is obtained when it is read for the first time, then the second status of the digital asset "BOTTLE PREVIOUSLY OPENED" will always be displayed, making it impossible to return to the first status of the bottle given the immutability and security of the blockchain. This dynamic digital asset can be associated with a type of dynamic NFT, such as a cryptoasset (NOT CRYPTOCURRENCY), and therefore, the system according to the invention constitutes a novel and inventive alternative for the traceability of products by manufacturers and users, in particular in the liquor industry, since it constitut

METHOD FOR SECURELY REMOVING BLOCKS FROM EXISTING BLOCKCHAIN

Resumen de: EP4700631A1

Die vorliegende Erfindung betrifft ein Verfahren zum sicheren Entfernen von Blöcken aus einer bestehenden Blockchain in einer abgeschlossenen Infrastruktur wie zum Beispiel einem Firmennetzwerk. Das vorgeschlagene Verfahren schafft den Vorteil, dass Einträge aus der verketteten Liste entfernt werden können, ohne, dass hier die weitere Integrität der Kette gefährdet ist. Blockchains sehen grundsätzlich nicht vor, dass Blöcke aus der Datenstruktur entfernt werden, was durch die redundante Speicherung verhindert wird. Die vorliegende Erfindung überwindet diesen Nachteil und schafft zudem einen Mechanismus, der es erlaubt die Datensätze nachträglich ggf. wieder herzustellen. Die Erfindung ist ferner gerichtet auf eine entsprechend eingerichtete Systemanordnung. Ferner wird ein Computerprogrammprodukt mit Steuerbefehlen vorgeschlagen, welche das vorgeschlagene Verfahren implementieren beziehungsweise die vorgeschlagene Vorrichtung und Anordnung betreiben.
