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.

摘要： The present invention enables execution of predetermined content usage control processing without depending on a framework of a content playback program (application). Upon content playback processing, a flag which sets information of determination as to whether or not it is necessary to refer to a management information file such as a token or a usage control information file associated with content is recorded in a content file including encrypted content to be stored in a recording medium. Upon the content playback processing, a playback apparatus acquires the content file including the encrypted content stored in the recording medium, refers to a flag recorded in the content file and determines whether or not it is necessary to refer to the management information file based on a setting of the flag. When the setting of the flag indicates that it is necessary to refer to the management information file, it is possible to select a correct management information file based on a content file identifier as a search key.
