摘要： This invention provides a license information management apparatus and the like that do not require a tamper resistance module with a large memory even in the case where a user possesses a large amount of content. A total control unit (113) specifies a content corresponding to a reproduction instruction received from a user (S202). Further, the total control unit (113) verifies whether or not there is a LT corresponding to the specified content in a secure flash unit (120). In the case where there is the LT in the secure flash unit (120) (S203: Yes) and information concerning the reproduction of the content is received from the content decryption unit (520) (S204: Yes), an encryption/decryption unit (114) decrypts the LT stored in the secure flash unit (120) using a TRM unique key (S205). After that, the encryption/decryption unit (114) updates details of the content reproduction condition information (511a), encrypts the updated details using the TRM unique key, and writes the encrypted TRM unique key into the secure flash unit (120) (S208).

摘要： To protect rights of a copyright owner of digital content, technology is required to prevent digital content on a recording medium from being copied onto another recording medium and played back. A key distribution server securely receives a media unique key from a recording medium device, generates a first title key different for each content, encrypts the generated first title key with the media unique key, encrypts the content with the first title key, and transmits the encrypted first title key to the recording medium device and the encrypted content to the recording device. The recording device securely receives the encrypted content from the key distribution server and the first title key and a second title key from the recording medium device, decrypts the encrypted content with the first title key, encrypts the decrypted content with the second title key, and transmits the encrypted content to the recording medium device.

摘要： A memory card and a recording/playback device are provided that are capable of deterring a memory card manufacturer from illicitly storing a same media ID on a plurality of memory cards. A memory card (100) includes a media ID storage module unit (610) and a memory unit (120). The media ID storage module unit (610) includes a media ID storage unit (611) that stores therein a media ID that is specific to the memory card, and a certification unit (609) that generates certification information that certifies the validity of the memory card based on the media ID. The memory unit (120) includes an encrypted content storage unit (122) for storing encrypted digital content. The recording/playback device (200) includes a memory card verification unit (200) that acquires the certification information from the memory card (100), verifies the validity of the memory card (100) based on the acquired certification information, and when the verification has failed, prohibits decrypting an encrypted content or encrypting a content, and a content encryption unit (209) that, when the verification has succeeded, encrypts the digital content or decrypts the encrypted digital content.
