Abstract

L'invention concerne un procédé de sécurisation d'un contenu stocké sur un support de données. Selon l'invention, on met en œuvre les étapes suivantes : lors d'une première phase de préparation de la sécurisation dudit contenu : détermination d'au moins une première information de contrôle représentative d'au moins une partie du contenu, calcul d'une signature d'intégrité à partir de la première information de contrôle, mémorisation de la première information de contrôle et de ladite signature d'intégrité ; lors d'une deuxième phase de restitution du contenu par un lecteur : lecture de la première information de contrôle et de la signature d'intégrité (317), vérification de la signature d'intégrité (318) ; si la signature est correcte : lecture d'au moins une partie du contenu (320), détermination d'au moins une seconde information de contrôle à partir de la lecture, authentification du contenu par corrélation des première et seconde informations de contrôle (321) ; si l'authentification est correcte, poursuite de la lecture du contenu.
