Abstract:
(EN) The present invention realizes, also at a content copy destination, a usage control configuration substantially similar to the content usage control on a copy source medium. The present invention includes: a data processing unit that copies, onto a second medium, recorded data on a first medium; and a storage unit that stores a correction title key (Kc) required for decrypting an encrypted content recorded on the first medium. The data processing unit records, onto the second medium, the encrypted content recorded on the first medium without performing decryption. The data processing unit determines whether the correction title key (Kc) stored in the storage unit belongs to category A, indicating being acquirable under a condition that authentication is established with a sever, or category B, indicating that establishment of authentication is not defined as a condition, and records, onto the second medium, the correction title key only when the correction title key belongs to category B.
(FR) La présente invention permet de réaliser, également au niveau d'une destination de copie de contenu, une configuration de commande d'utilisation sensiblement similaire à la commande d'utilisation de contenu sur un support de source de copie. La présente invention comprend : une unité de traitement de données qui copie, sur un second support, des données enregistrées sur un premier support; et une unité de mémorisation qui mémorise une clé de titre de correction (Kc) nécessaire pour le déchiffrement d'un contenu chiffré enregistré sur le premier support. L'unité de traitement de données enregistre, sur le second support d'enregistrement, le contenu chiffré enregistré sur le premier support sans effectuer de déchiffrement. L'unité de traitement de données détermine si la clé de titre de correction (Kc) mémorisée dans l'unité de mémorisation appartient à une catégorie A, indiquant que celui-ci peut être acquis à une condition selon laquelle l'authentification est établie avec un serveur, ou à une catégorie B, indiquant que l'établissement d'authentification n'est pas défini en tant que condition, et enregistre, sur le second support, la clé de titre de correction uniquement lorsque la clé de titre de correction appartient à la catégorie B.
(JA) コンテンツのコピー先においても、コピー元メディアにおけるコンテンツ利用制御とほぼ同様の利用制御構成を実現する。第1メディアの記録データを第2メディアにコピーするデータ処理部と、第1メディアに記録された暗号化コンテンツの復号に必要となる補正タイトルキー(Kc)を格納した記憶部を有する。データ処理部は、第1メディアに記録された暗号化コンテンツを復号することなく第2メディアに記録する。また、記憶部に格納された補正タイトルキー(Kc)が、サーバとの認証成立を条件として取得可能なカテゴリAであるか、認証成立を取得条件としないカテゴリBであるかを判別し、カテゴリBの補正タイトルキーである場合に限り、第2メディアに記録する。
