Abstract

La présente invention porte sur un procédé d'anonymisation de transactions d'une chaîne de blocs, lequel permet par exemple au propriétaire d'un objet d'obtenir une information concernant des transactions ou bases de données antérieures dans un historique de données ou chaîne de blocs, mais non aux propriétaires futurs. Par exemple, une information concernant l'entretien d'un véhicule peut être rendue toujours disponible pour le propriétaire actuel, sans que ce propriétaire actuel ne puisse accéder à des informations concernant des propriétaires futurs. L'invention se rapporte également à un protocole de communication mis en œuvre de manière correspondante ainsi qu'à un système de communication pour l'anonymisation de transactions d'une chaîne de blocs. L'invention concerne en outre un produit programme d'ordinateur, comportant des instructions de commande qui exécutent le procédé selon l'invention, autrement dit mettent en oeuvre le système de communication selon l'invention.
