Abstract[English]
A system and method for linking authentication documents to a piece of artwork using blockchain. The method includes maintaining a blockchain with a plurality of computing devices; obtaining one or more documents comprising data corresponding to a piece of artwork; generating a document hash for each of the one or more documents based on text contained in the respective documents; generating a frequency hash based on a light wave frequency; appending a block instance to the blockchain by generating a block address based on the document hashes for the one or more documents, the frequency hash, and an identification of the piece of artwork; and transmitting instructions to a seal coating device, receipt of the instructions causing the seal coating device to apply a seal coating to the piece of artwork and a certificate containing the document hashes for the one or more documents.[French]
L'invention concerne un système et un procédé destinés à lier des documents d’authentification à une œuvre d’art à l’aide d’une chaîne de blocs. Le procédé comprend les étapes consistant à entretenir une chaîne de blocs avec une pluralité de dispositifs informatiques; à obtenir un ou plusieurs documents comportant des données correspondant à une œuvre d’art; à générer un hachage de document pour le ou chacun des documents sur la base d’un texte contenu dans les documents respectifs; à générer un hachage de fréquence sur la base d’une fréquence d’onde lumineuse; à adjoindre une instance de bloc à la chaîne de blocs en générant une adresse de bloc d’après les hachages de documents relatifs au(x) document(s), le hachage de fréquence, et une identification de l’œuvre d’art; et transmettre des instructions à un dispositif de revêtement de scellage, la réception des instructions amenant le dispositif de revêtement de scellage à appliquer un revêtement de scellage à l’œuvre d’art et à un certificat contenant les hachages de documents relatifs au(x) document(s).
