发明名称 METHOD FOR SAVING THE KEYLOCKERS ON OPTICAL DISCS
摘要 The present invention relates to a system with an integrated digital rights management mechanism. The system comprises a drive (120) and a host (130) controlling operations of the drive (120). The drive (120) receives an optical record carrier (102) and is designed to extract from the optical record carrier (102) a digital rights file including keys and rights respecting access to content (304) stored on the optical record carrier (102). The host (130) generates a dummy file (310) bearing structural characteristics similar to the driver digital rights file and transmits the dummy file (310) to the drive (120). Upon reception of the dummy file (310), the drive (120) completes the dummy file (310) by incorporating into the dummy file (310) sensitive data contained in the digital rights file and writes the dummy file (310) onto the carrier (102).
