Abstract: A device and method for protection of legitimate software against used software and counterfeit software in recording media. The device includes a disk is set in a main unit. A specific title code is read, and if this title code has been registered, the main unit shifts to a normal operation. If the code has not been registered, verification software is initiated, PG detection is performed, and when a PG pattern and verification data match, the code is registered in the COCT. If matching does not occur, the disk is processed as illegitimate software.
