Abstract

La présente invention concerne un milieu d'enregistrement d'informations (1) qui comprend une zone d'enregistrement de contenu (34) dans laquelle un contenu est codé par un procédé d'encodage prédéfini et enregistré, une zone enregistrée (33a) d'informations d'authentification pour un lecteur dans lequel des premières informations d'authentification de milieu qui sont adressées par un dispositif de lecture lors de l'authentification du milieu d'enregistrement d'informations entre le dispositif de lecture et un ordinateur hôte sont enregistrées, et une zone enregistrée (34a) d'informations d'authentification pour un ordinateur dans lequel des secondes informations d'authentification de milieu qui sont obtenues par l'encodage des mêmes informations que les premières informations d'authentification de milieu et qui sont adressées par l'ordinateur hôte lorsque l'exécution de l'authentification sont enregistrées. Le procédé d'encodage permet de décoder le contenu par l'ordinateur hôte à l'aide d'une clé d'encodage qui peut être acquise à condition que l'authentification soit terminée. Ceci prévient des comportements d'enregistrement abusifs par le procédé d'encodage comparativement simple.
