Abstract

La présente invention concerne un procédé de service d'authentification de permis de conduire basé sur un réseau de blocs utilisant un ID décentralisé (DID), ainsi qu'un terminal utilisateur permettant la mise en œuvre de ce procédé, le procédé mis en œuvre par le terminal permettant : à un serveur d'authentification de permis de conduire de demander des informations d'authentification d'utilisateur au terminal utilisateur dans un état où un DID utilisateur et des informations publiques d'utilisateur sont enregistrés dans un réseau de chaîne de blocs et où un VC utilisateur pour des informations utilisateur est émis et stocké dans le terminal utilisateur ; à des informations d'authentification d'utilisateur, comprenant le DID utilisateur, le VC utilisateur et une valeur de signature d'utilisateur signée en utilisant le VC utilisateur comme clé privée d'utilisateur, d'être transmises au serveur d'authentification de permis de conduire ; et au serveur d'authentification de permis de conduire d'acquérir une clé publique d'utilisateur à partir du réseau de chaîne de blocs en utilisant le DID utilisateur, de vérifier la valeur de signature de l'utilisateur à l'aide de la clé publique d'utilisateur, d'authentifier le VC utilisateur, de générer un VC de permis de conduire utilisateur si le VC utilisateur est authentifié, et de transmettre le VC du permis de conduire de l'utilisateur VC au terminal utilisateur.
