摘要： An information processing apparatus includes a data processor and a storage. The storage is divided into a protected area to which access is limited and a general purpose area which is freely accessible, and configured to store in the general purpose area encrypted content, and an encrypted title key obtained by encrypting a title key to be applied to decrypt the encrypted content, and store in the protected area a binding key applied to encrypt the title key, and a hash value of the encrypted title key. The data processor is configured to determine, in response to a request for access to the protected area from an external apparatus, whether or not to permit the access, and permit, only when access permission determination is made, the access to the protected area.

摘要： To realize a configuration to output content to a medium and to use the content stored in the medium under control of the use of content.A content-output-device outputs an encrypted content and an encryption key to be applied to the using process to the medium, and a management server generates a media ID verification value based on a media ID that is an identifier of the medium and transmits the value to the medium. The medium stores the encrypted content, the encryption key, and the media ID verification value in a storage unit. A reproduction device loads the medium and calculates a verification value based on the media ID acquired from the medium, and executes a reproducing process of the encrypted content stored in the medium by data processing to which the encryption key is applied on condition that a matching process performed between the verification value and the media ID verification value stored in the medium is established.
