Abstract

Digital Watermarking is an important and finest method of protecting the copyright of the digital media. In this paper, a secure and robust digital video watermarking algorithm is proposed, that is Color Watermark Embedding Algorithm (CWEA). This algorithm 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 watermark into the detail coefficients of CHROMINANCE (Cb and Cr- chrominance) of identical frames (I-Frames) of digital video. Watermark data is inserted into the detail coefficients in an adaptive manner based on the energy of high frequency. We have performed number of tests 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 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.
