Abstract

L'invention concerne un procédé de vérification de l'authenticité de ressources numériques authentifiées. Le procédé comprend les étapes suivantes dans lesquelles : un client envoie des données de ressources numériques authentifiées à une plate-forme d'enregistrement de ressources numériques ou à un réseau de chaînes de blocs ; et la plateforme d'enregistrement de ressources numériques ou le réseau de chaînes de blocs vérifie l'authenticité d'une entité ou d'un code d'authentification dans les données de ressources numériques authentifiées obtenues et renvoie un résultat de vérification au client. Selon le procédé décrit dans la présente invention, la plateforme d'enregistrement de ressources numériques ou le réseau de chaînes de blocs extrait une valeur de hachage avec l'authenticité pour vérifier l'authenticité d'une entité de ressources numériques reçue par le client, de sorte que le client puisse confirmer si l'entité de ressources numériques reçue est une entité authentique et effectuer une opération correspondante sur l'entité authentique ou une fausse entité, garantissant ainsi qu'une transaction de ressources numériques est réalisée de manière efficace.
