Method for authenticating and anti-counterfeiting coffee machines or coffee grinders

Abstract

Method for authenticating and anti-counterfeiting coffee machines or coffee grinders, comprising the steps of: acquiring by means of a web server identification data associated with a coffee machine or a coffee grinder; generating encrypted data by executing a hash function of the identification data; generating a digital certificate associated with a public key and a private key; storing the encrypted data in a blockchain by means of unique association with the public key of the digital certificate using the private key of the digital certificate; storing the public key and the private key in the database installed in the coffee machine or in the coffee grinder; sending the control unit of the coffee machine or the coffee grinder, by means of an application residing in a mobile device, an authentication request containing a message with the public key; in response, sending by means of the control unit the digitally signed message with the private key stored in the database to the application; sending the signed message to the web server by means of the application; sending to the web server an authentication request notification by means of the communication between the control unit and the web server when the communication unit receives the authentication request; sending to the blockchain by means of the web server the signed message received by the application; identifying the absence of counterfeiting of the coffee machine or of the coffee grinder only if the blockchain identifies that the signed message associated with the coffee machine or with the coffee grinder is authentic when both the public key and the private key of the digital certificate match.
