The CPRM/CPPM Specification defines a renewable cryptographic method for protecting entertainment content when recorded on removable and portable physical media including, but not limited to, DVD media and Flash memory. 4C Entity also created a comprehensive framework for unifying various content protection technologies. The Content Protection System Architecture (CPSA) was developed to integrate major existing content protection technologies from the personal computing and consumer electronics industries, as well as new technologies as they emerge in the years ahead.
