Digital Rights Management
Digital rights management (DRM) software uses encryption to
enforce copyright restrictions on digital media. Over the past decade,
publishers attempted to deploy DRM schemes across a variety of
media types, including music, movies, and books. In many cases,
particularly with music, opponents met DRM deployment attempts
with fierce opposition, arguing that the use of DRM violated their
rights to freely enjoy and make backup copies of legitimately licensed
media files.
As you will read in this section, many commercial
attempts to deploy DRM on a widespread basis failed when users
rejected the technology as intrusive and/or obstructive.
