디지털 콘텐츠 서비스 제공자들이 증가함에 따라, 다양한 DRM 시스템들이 상호호환성에 대한 고려 없이 개발되었다. DRM 시스템 간의 상호호환성 부재는 소비자들이 콘텐츠를 다양한 디바이스 환경에서 사용하지 못하도록 하고 있으며 디바이스 제조자들에겐 다양한 DRM을 지원해야 하는 부담을 주고 있다. 본 논문에서는 서로 다른 DRM 시스템 사이에 상호호환성을 지원하기 위한 새로운 방법을 제안한다. ‘툴팩’이라 불리는 본 기술은 Open Frame Work 기반으로 기존의 Open Frame Work 기반의 DRM 기술이 가지고 있던 약점인 DRM 툴(Tool)의 보안성을 높이는 동시에 새로운 DRM 툴을 추가하기 위한 확장성과 인터페이스의 간략화로 효율성을 증가시키는 효과가 있다.
