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.

摘要： A configuration is provided wherein usage restrictions of an application are determined in accordance with timestamps. A certificate revocation list (CRL) in which the revocation information of a content owner who is a providing entity of an application program recorded in a disc is recorded is referred to verify whether or not a content owner identifier recorded in an application certificate is included in the CRL, and in the case that the content owner identifier is included in the CRL, comparison between a timestamp stored in a content certificate and a CRL timestamp is executed, and in the case that the content certificate timestamp has date data equal to or later than the CRL timestamp, utilization processing of the application program is prohibited or restricted. According to the present configuration, a configuration is realized wherein an unrevoked application is not subjected to utilization restriction, and only a revoked application is subjected to utilization restriction.

摘要： There are provided an information providing system, a reproduction device and method, an information providing device and method, a recording medium, and a program capable of comparatively freely utilizing the content recorded on a disc according to the user preference. When download of an audio file of Japanese language is instructed, the update file of the content recorded on the optical disc (11) is downloaded. The Audio stream file as an audio file of Japanese language, the Clip Information file accompanying it, the Play List file controlling the reproduction of the Audio stream file, and the navigation program file which has been updated are recorded as the update file in a local storage (12). By the navigation program which has been updated, for example, the Audio stream file of Clip 3 as the Japanese language audio is reproduced. The present invention can be applied to a player to which a recording medium where the content has been recorded is detachably attached.
