최근 들어 새로운 형태의 디지털 콘텐츠 관련 시장과 기술 분야가 등장하고 컨버전스나 통방 융합과 같은 흐름에 따라 기존의 산업에 많은 변화가 가해지고 있는데, 이는 기존의 산업에 대한 국외 선도 업체들의 영향력이 약화되고 있음을 의미하고, 새로운 산업 형태에 대해 기술과 표준에 대한 주도권을 확보하기 위한 경쟁이 심화됨을 의미한다. DRM 기술 관련 분야에서도 이러한 현상이 나타나고 있는데, 향후 가장 큰 시장으로 예상되는 디지털 홈 관련 DRM 기술 분야에서 이미 여러 업체 및 표준화 단체를 중심으로 주도권 경쟁을 하고 있다. 본 고에서는 디지털 홈 환경에서의 콘텐츠 보호를 위한 DRM 요소 기술에 대하여 살펴보고, 각 요소 기술 분야에서 강점을 보이는 주요 DRM 기술들에 대하여 설명한다.
