The Clearinghouse Model Supporting Multiple DRMs

다수 DRM 지원 클리어링하우스 모델


Abstract

The DRM system has a clearinghouse module which is in the Important position in content delivery mechanism. Currently, the most of DRM systems in the market does not support compatibility functions with other DRM systems. The shopping malls must consider the multiple clearinghouses services if they have many contents using diverse DRMs. In this paper, we are modelling a clearinghouse module which can support several DRM systems. As a first step, this model supports Microsoft WMT Adobe ACS, and our own DRM system.

현재 시장에 유통되는 대부분의 DRM 시스템은 자체적으로 클리어링하우스를 가지고 있으며, 클리어링하우스는 컨텐츠 유통 메카니즘에서 중요한 역할을 차지하고 있다. 본 연구에서는 DRM 기능에서 중요한 위치를 차지하는 클리어링하우스 기능을 통합하여, 어떤 DRM으로부터 요구가 발생하여도 지원할 수 있는 다수 DRM 지원 클리어링하우스를 모델링하였으며, 초기 형태로 대표적인 Microsoft톤의 WMT, Adobe의 ACS 그리고 자체 DRM인 MR_DRM을 지원하는 체계를 구축하였다.
