멀티미디어 콘텐츠를 저작, 생성, 전달을 통해 최종 소비에 이르기까지 콘텐츠를 보호하고 안전하게 다루기 위해 MPEG-21 IPMP(Intellectual Property Management and Protection)가 표준을 정의하고 있으며 현재 FCD(Final Committee Draft) 단계까지 표준화가 이루어졌다. 우리는 MPEG-21 IPMP에서 규정한 FCD규격에 따라 멀티미디어 콘텐츠와 그에 대한 저작권을 보호 관리하는 시스템을 개발하였다. 제안한 MPEG-21 기반 REL및 IPMP 보호 관리 시스템은 크게 보호 관리 메타데이터 생성부, 통합 제어 관리부, 디지털 아이템 암호화부, 네트워크 인터페이스부의 4부분으로 구성된다. 이 시스템은 먼저 라이센스 서버를 통해 MPEG-21 REL(Rights Expression Language) 규격에 맞는 라이센스 정보가 담긴 문서를 파싱하는 기능을 가지며 오디오 또는 비디오 워터마크가 적용된 멀티미디어콘텐츠에 대해 MPEG-21 IPMP 기반의 메타데이터를 생성하고 보호 관련 REL및 IPMP 메타데이터와 멀티미디어 콘텐츠를 Remuxing 하여 전송되며 멀티미디어 콘텐츠 및 하나의 패키징된 DID는 암호화하여 최종 소비자에게 전송한다.
