Encyclopedia > Content Protection for Recordable Media
CPRM or Content Protection for Recordable Media is a mechanism for controlling the copying, moving and deletion of digital media on a host device, such as a personal computer, or other digital player. It is a form of Digital rights management developed by The 4C Entity, LLC.
A controversial proposal to embed CPRM in ATA hard drives was abandoned due to popular outcry in 2001. However, as of 2004, CPRM is widely deployed in the popular Secure Digital Card consumer-electronics Flash memory format with no apparent notice from electronic personal-rights advocates.
It is probably significant that although CPRM-capable storage formats such as Secure Digital are now widely available, the use of CPRM in these formats is not mandatory. Users are able to ignore the rights-management features entirely if they so choose, and for example can freely copy MP3 music files to and from personal music players or PDAs based on Secure Digital cards with no restrictions. Only special CPRM-enabled media formats, which do not yet seem to have achieved market visibility, will impose copying restrictions.
