A Novel Approach to Digital Contents Sharing for Digital Home Network

Abstract

The purpose of Digital Rights Management (DRM) is to prevent the illegal copying and distribution of digital contents. Common DRM, however, is inappropriate for a digital home environment that consists of family members and devices. Different family members need different access rights to DRM contents in their home networks. This paper presents a novel approach to digital contents sharing for digital home network. This approach adopts the idea of Role-Based Access Control (RBAC) and license chain and allows digital contents sharing to be convenient and controlled. Through analyzing the performance of the approach, we conclude that this novel approach is more secure and flexible, and it satisfies the requirement of digital home networks.
