Abstract
The smart devices and cloud computing technology have been introduced into a new content service such as N-Screen service. The DRM(digital rights management) techniques have been rapidly developed in accordance with the new service environment after the awareness on the importance of DRM technology. In spite of the technical advancement of DRM, it is being taken as an unwelcome thing by the content consumers until now. In the Cloud era, the rapid introduction of service is possible and also the importance of content protection is going to increase more and more. As a result, the DRM technology should be changed to match the nature of the Cloud as well. In this paper, a model of DRM-as-a-Service for content protection within the Cloud, which is referred to as DRM Cloud, and an architecture of DRM Cloud are proposed. Also we describe the content download service by using the DRM Cloud and discuss about the establishment of the trusted DRM Cloud and its advantages.
