본 논문에서는 디지털콘텐츠 식별자 연계 표준인 UCI 정보를 이용하여 효율적인 디지털 콘텐츠의 관리가 가능한 무손실 비디오 워터마킹 기법을 이용하였다. 제안한 기법은 각 비디오 프레임의 히스토그램의 특정 구간의 화소값을 수정함으로써 워터마크를 삽입한다. 4CIF 크기의 테스트 시퀀스를 통한 실험결과 화질의 열화가 적으면서도 UCI 정보를 100% 왜곡없이 검출이 가능하였으며, 원본 디지털 비디오 콘텐츠도 모든 테스트 시퀀스에서 100% 복원이 가능하였다. 제안한 기법은 디지털 비디오에 UCI 정보를 직접 삽입하여 메타데이터가 없을 경우 콘텐츠만으로도 콘텐츠의 식별이 가능하고 콘텐츠로부터 추출한 UCI 정보를 통하여 효율적인 관리가 가능하면서 유사시 원본 콘텐츠를 손실없이 복원이 가능할 수 있어 영화, 방송 등의 다양한 비디오 콘텐츠의 관리를 위해 응용될 수 있다.
