Abstract

L'invention concerne un procédé et un appareil de traitement de données d'entreprise à base de chaîne de blocs, un dispositif et un support de stockage. Ledit procédé comprend les étapes suivantes : acquérir, à partir d'un nœud correspondant d'une chaîne de blocs, des données d'entreprise à authentifier, comprenant des données d'origine et des premières données d'étiquette calculées par un sujet d'authentification (S202) ; interroger un niveau de confiance correspondant au sujet d'authentification, et déterminer si le niveau de confiance est inférieur à une valeur prédéfinie (S204) ; lorsque le niveau de confiance n'est pas inférieur à la valeur prédéfinie, acquérir un contrat intelligent actuel et un contrat intelligent historique auprès du nœud correspondant de la chaîne de blocs (S206) ; déterminer une clause présentant des différences selon le contrat intelligent actuel et le contrat intelligent historique, calculer, selon les données d'origine, des deuxièmes données d'étiquette correspondant à la clause présentant des différences, et authentifier les deuxièmes données d'étiquette selon la clause présentant des différences (S208) ; selon que l'authentification des deuxièmes données d'étiquette est réussie, que l'authentification des deuxièmes données d'étiquette n'est pas réussie, et les premières données d'étiquette, effectuer un calcul pour obtenir un taux de réussite de données à authentifier (S210) ; lorsque le taux de réussite de données à authentifier est supérieur à un taux de réussite standard, déterminer que les données d'entreprise à authentifier réussissent l'authentification (S212).
