인터넷의 급속한 확산은 디지털 콘텐츠 시장을 활성화 시켰으나 무분별한 불법 복제와 유통으로 디지털 콘텐츠 시장이 위축되고 있다. MPEG(Moving Picture Experts Croup)은 이러한 문제를 해결하기 위하여 MPEG-21 Multimedia Frameworks를 제안하였다. IPMP(Intellectual Property Management and Protection)는 MPEG-21 Multimedia Frameworks의 세부 분야로 디지털 콘텐츠가 생성, 전달, 소비를 거치는 과정에서 디지털 콘텐츠를 안전하게 다루기 위한 표준을 정의하는 것으로 FCD(Final Committee Draft) 단계까지 표준화가 이루어졌다. 따라서 디지털 콘텐츠의 저작권을 보호 관리하기 위하여 IPMP의 최신 표준화 내용을 적용한 시스템 개발이 요구되었고, 이에 따라 디지털 콘텐츠를 보호 관리하는 시스템을 크게 저작 서버, 틀 서버, 라이센스 서버, 소비 서버의 네 개 구조로 구분하였다. 이에 본 논문에서는 라이센스 서버로부터 전송된 콘텐츠의 정보가 담긴 REL(Rights Expression Language) 문서 파싱 기능과 워터마크가 적용된 콘텐츠에 대한 MPEG-21 IPMP 기반의 메타데이터 생성 및, Remuxing 과정을 거친 데이터를 암호화하여 소비 서버로 전송하는 저작 시스템에 대하여 설계 및 구현하였다.
