오늘날 상용화된 DRM(Digital Rights Management) 제품들은 많이 있으나 DRM간 상호 호환성이 없는 상태이다. DRM간 호환성 결여로 인하여 사용자의 불편은 증대되고 디지털 콘텐츠의 유통은 제한된 범위로 제약을 받고 있다. 이러한 문제점을 해결하기 위하여 DRM의 호환성 지원을 위해 DRM 표준화에 대한 요구가 증대되고 있으나 지배적 위치의 DRM 표준이 마련되지 않아 호환성 문제를 해결하지 못하고 있는 상태이다. 이에 본 논문은 MP3 파일의 저작권보호를 위해 사용되는 상이한 DRM 시스템간 상호 호환을 위한 보완재적 DRM 기술로써 DRM 콘텐츠의 반출(EXport) 및 반입(IMport)을 통한 연동 방안(EXIM)을 제안한다. 제안하는 EXIM 방안은 상호 연동이 필요한 두 DRM 시스템이 자신의 구조를 공개하거나 변경하지 않고도 개방형 기술규격을 통해 DRM 콘텐츠를 상호 호환될 수 있도록 한다.
