Abstract

Because the embedded watermark of luminance component guarantees the extraction of ownership information when the color image is converted to gray scale image, the information of ownership right as to the luminance component is embedded in the luminance-chrominance color space such as YCbCr. Therefore, this paper proposes watermark embedding, extraction and authentication algorithm of color image. which considers the device and performance of multimedia contents service by focusing on the robustness and invisibility of watermark. The color image is converted from RGB color space to YCbCr color space, and then the properties of each component of Y(Luminance), Cb(Color Differences) and Cr(Color Differences) are considered in order to embed, extract and certify multi-level watermark in the frequency domain based on the wavelet. As a result, it can guaranteed the robustness for the JPEG compression and invisibility of watermark for multi-level.

광도 요소의 워터마크 내장은 컬러 영상을 그레이 스케일 영상과 같은 변형에서 삽입한 소유권 정보의 추출을 보장하기 때문에 YCbCr와 같은 광도-색차 컬러 공간에서 색상의 광도 요소에 소유권 정보를 내장한다. 따라서 본 논문은 워터마크의 견고성과 비시각성에 중점을 두고, 멀티미디어 컨텐츠서비스의 장치와 성능을 고려한 컬러 영상의 워터 마크 내장, 추출 및 인증 알고리즘을 제안한다. 컬러 영상은 RGB 컬러 공간에서 YCbCr 컬러 공간으로 변형 한 다음 Y(Luminance), Cb(Color Differences) 및 Cr(Color Differences) 각 요소의 특성을 고려하여 웨이브릿 기반의 주파수 영역에서 다중 레벨(Multi-Level)의 워터마크를 내장하고 추출 및 인증한다. 실험 결과, JPEG 압축에 따른 견고성과 다중 레벨에 대한 워터마크의 비 시각성을 보장할 수 있었다
