摘要： To provide an apparatus, a recording medium and a method for effectively preventing unauthorized use of a content. A content containing broken data different from correct content member data is recorded on an information recording medium. Furthermore, transform data, as the correct member data, to be substituted for the broken data, and a fix-up table storing setting position information of the content are recorded on the information recording medium. During the content playback process, the transform data is substituted for the content member data in accordance with the fix-up table recorded on the information recording medium. With this arrangement, even if the encryption key corresponding to the encrypted content recorded on the information recording medium is leaked, an apparatus unable to acquire the transform data cannot play back the content. Unauthorized use of the content is thus controlled.

摘要： A data placement configuration which ensures seamless playback of contents having segment portions including multiple different variations of encrypted data is provided. With regard to contents having segment portions configured of multiple different variations of encrypted data to which individual segment keys have been applied, and non-segment portions serving as encrypted data to which a unit key has been applied, the placement of segment data and non-segment portion configuration data is determined such that the maximum jump distance executed at the time of playback processing is equal to or less than a maximum jump distance set beforehand. Data placement has been determined based on seek time, ECC block processing time, sequence key usage time which is key switchover time, and so forth.

摘要： A configuration for achieving efficient content verification processing based on hash values is provided. Hash values of hash units set as segmented data of a content stored on an information storage medium are recorded in a content hash table and are stored on the information storage medium together with the content. An information processing apparatus for executing content playback executes hash-value comparison processing based on one or more randomly selected hash values. Regardless of the data amount of content, the configuration can perform hash-value determination and comparison processing based on hash units having a small amount of data, so that user equipment for executing content playback can perform efficient content verification.
