    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： An information recording medium manufacturing method includes the steps of: determining an encryption mode of each sector, which serves as an encrypt processing unit; generating encrypted data having different variations by using a plurality of cryptographic keys for a segment portion; generating encrypted data by using a single cryptographic key for a non-segment portion; and recording the encrypted data. In determining the encryption mode, a cryptographic key for each sector is specified on the basis of an auxiliary file including determination information indicating whether each sector is data of a segment portion or data of a non-segment portion and identification information for identifying a segment and a variation associated with the sector if the sector is found to be the data of a segment portion. In generating the encrypted data for the segment portion or for the non-segment portion, the encrypted data is generated by using the specified cryptographic key.
