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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Information processing apparatus, information recording medium manufacturing apparatus, information recording medium, method, and computer program","description":"To provide an apparatus, a recording medium and a method for effectively preventing unauthorized use of a content.
