DISC MANUFACTURING METHOD, DATA RECORDING DEVICE, INFORMATION RECORDING MEDIUM, INFORMATION PROCESSING DEVICE AND METHOD, AND COMPUTER PROGRAM

摘要

A disc manufacturing method generates an encryption volume ID calculated according to a product mark containing a public key certificate issued to a disc manufacturing entity or a disc manufacturing device, a product mark corresponding value such as a Hash value generated according to the product mark, and a volume ID as an identifier set for a certain set of the manufactured discs and records the product mark and the encryption volume ID as information for generating a decoding key for the encrypted content on the disc by the reflection film removal recording method. With this configuration, it is impossible to read a product mark or an encryption volume ID as key generation information from a pirated disc onto which a pit shape is physically copied according to an authorized disc on market, thereby preventing unauthorized reproduction or use of a content.
