摘要：Digital Watermarking is an important method of protecting the intellectual property and copyright of the digital media. In this paper, a new digital video watermarking algorithm Color Watermark Embedding Algorithm (CWEA) is proposed. CWEA has two important parts. First, YCbCr color format is used to insert the variable size watermark. Second, embedding of detail coefficients of LUMINANCE (Y-luminance) of the watermark into the detail coefficients of CHROMINANCE (Cb and Cr- chrominance) of identical frames (I-Frames) of digital video. Data is inserted into the detail coefficients in an adaptive manner based on the energy of high frequency. A number of tests have been executed for many video-frame manipulations and attacks. All these tests are also performed on CWEA and it provides good results. In this paper, non-blind and semi-blind watermarking systems are used where the non-blind watermarking mechanism has been proved to be robust, imperceptible and efficient to protect the copyright of H.264 and MPEG-4 coded video within the video retrieval system.
