CPPM, which stands for Content Protection for Recordable Media and Pre-Recorded Media, is a digital rights management (DRM) mechanism developed by The 4C Entity, LLC consisting of IBM, Intel, Matsushita, and Toshiba. CPPM is created to ensure that copying, moving, and deleting digital media is controlled and restricted on a host device such as a personal computer or playback device.
CPPM uses the Cryptomeria Cipher (C2) algorithm to implement a renewable cryptographic method that restricts content recorded on physical media like recordable DVD media and flash memory. It’s mostly used in Secure Digital cards such as the SD Audio standard.
