디지털 비디오와 디지털 방송의 출현으로 비디오 데이터의 저작권 보호는 가장 중요한 이슈 중 하나가 되었다. 우리는 이 논문에서 이산 웨이블릿 변환을 기반으로 한 비디오 데이터에 대한 디지털 워터마크의 새로운 방법을 제시합니다. 이 방법에서는 제어된 양자화 프로세스를 사용하여 코딩되지 않은 비디오의 각 프레임의 가장 낮은 주파수 구성 요소에 워터마크를 삽입합니다. 원본 영상에 접근하지 않고도 디코딩된 영상에서 직접 워터마크를 추출할 수 있습니다. 실험 결과는 제안된 방법이 더 나은 품질의 워터마크 이미지를 제공하고 MPEG 코딩 및 재인코딩에 강인함을 보여줍니다. 또한, 영상 콘텐츠의 세대별 복사 제어와 관련하여 다중 워터마킹에 대해 논의한다.

vol. E83-A, no. 1, pp. 90-96, January 2000, doi: .
Abstract: With the advent of digital video and digital broadcasting, copyright protection of video data has been one of the most important issues. We present in this paper a novel method of digital watermark for video data based on the discrete wavelet transform. In this method, we embed the watermark in the lowest frequency components of each frame in the uncoded video by using a controlled quantization process. The watermark can be extracted directly from the decoded video without access to the original video. Experimental results show that the proposed method gives the watermarked image of better quality and is robust against MPEG coding and re-encoding. Furthermore, we discuss multiple watermarking with regard to the generational copy control for video contents.
