The advent of consumer digital media products has vastly increased the concerns
of copyright-dependent organizations within the music and movie industries.
While analog media inevitably loses quality with each copy generation, digital
media files may be duplicated an unlimited number of times with no degradation
in the quality of subsequent copies. This combined with the Internet and popular
file sharing tools, has made unauthorized distribution of copies of copyrighted
digital media much easier. The Digital Rights Management (DRM) field was thus
spawned to prevent unauthorized access to digital content. The DRM solutions
exist as either proprietary products owned by companies or as open standards.
Most of the implemented DRM solutions suffer mainly from interoperability
issue. In this work, we propose a new DRM system which overcomes the
interoperability issue which exists in today’s DRM products. This new DRM
system is called Digital Rights Unit System (DRUS).
