Abstract

Les modes de réalisation de la présente invention concernent un procédé, un dispositif et un support de mémoire qui permettent de protéger un ouvrage et qui sont fondés sur une chaîne de blocs. Le procédé consiste à recevoir, d'un dispositif auteur de l'ouvrage, des informations de certification et des informations de description de l'ouvrage associées à ce dernier, les informations de certification indiquant qu'un droit d'auteur de l'ouvrage a été certifié par une autorité de certification ; à attribuer un identifiant unique à l'ouvrage ; à déterminer si les informations de certification correspondent aux informations de description de l'ouvrage ; en réponse à la détermination du fait que les informations de certification correspondent aux informations de description de l'ouvrage, à enregistrer les informations de certification et l'identifiant unique de l'ouvrage sur une plate-forme de chaîne de blocs. Grâce à la solution offerte par la présente invention, une affirmation et une vérification de propriété pour des ouvrages peuvent être obtenues, la fuite et la falsification d'ouvrages qui peuvent se produire dans une plate-forme centralisée pouvant ainsi être évitées.
