A Digital Rights Management System Based on Cloud
Abstract: In the current
Internet, digital entertainment contents, such as video or audio files, are
easily accessible due to the new multimedia technologies and to broadband
network connections. This cause is considerable economic loss to global media
players since digital contents, once legitimately obtained, can be
illegitimately shared through file sharing services on the Internet. Digital
Rights Management (DRM) systems have been proposed to support the protection of
copyrighted digital contents. Even though such systems have been widely adopted
and promoted by global media players, they are based on proprietary mechanisms
that usually work only in closed, monolithic environments. In this regard,
systems based on watermarking technologies appear more suited to protect
digital copyrighted content. This paper describes the implementation scheme of
a DRM system able to ensure the copyright protection of digital content according
to an innovative buyer-friendly watermarking protocol. The DRM system has been
implemented by exploiting a cloud environment in order to improve the overall
performance of the system. In particular, cloud behaves as a service
infrastructural provider, since the content provider involved in the
watermarking protocol uses cloud to speed up the watermark embedding process
and to save storage and bandwidth costs needed to store and to deliver
protected contents.
