Abstract

Procédé pour la sauvegarde et la restauration d’un secret (S) détenu par un premier portefeuille de cryptoactifs (CW1), comprenant les étapes consistant à générer, au moyen du portefeuille de cryptoactifs, une pluralité de données secrètes (Si) à partir du secret (S), sauvegarder les données secrètes dans une pluralité de serveurs de sauvegarde (BCKi), et restaurer le secret dans un deuxième portefeuille de cryptoactifs à partir des données secrètes détenues par les serveurs de sauvegarde. L’étape de sauvegarde est précédée d’une étape initiale de collecte d'informations relatives à l’identité de l’utilisateur, et d'une étape de communication, à chaque serveur de sauvegarde, des informations relatives à l’identité de l’utilisateur. L’étape de restauration est précédée d’une pluralité d’étapes de vérification de l’identité de l’utilisateur par des serveurs de sauvegarde, ces derniers étant configurés pour refuser de restituer la donnée secrète qu’ils détiennent si la vérification de l’identité de l’utilisateur n’est pas concluante. Figure pour l'abrégé : Fig. 3AMethod for backing up and restoring a secret (S) held by a first cryptoasset wallet (CW1), comprising the steps of generating, by means of the cryptoasset wallet, a plurality of secret data (Si) from the secret (S), backing up the secret data in a plurality of backup servers (BCKi), and restoring the secret in a second cryptoasset wallet from the secret data held by the backup servers. The backup step is preceded by an initial step of collecting information relating to the identity of the user, and a step of communicating, to each backup server, information relating to the identity of the user. The restoration step is preceded by a plurality of steps of verifying the identity of the user by backup servers, the latter being configured to refuse to restore the secret data that they hold if the verification of the identity of the user is not conclusive.
