Video Watermarking using DWT and Alpha Blending Technique

Abstract: In cyber world, protection of copyrighted information is catching its attention due to the accessibility of immense amount of data and its copies in digital form. An efficient method of protecting this copyrighted information is by Digital Watermarking. In this paper, Discrete Wavelet Transform (DWT) and Alpha Blending Techniques are used. The video is converted into frames and DWT is applied on the frames and the watermark, alpha blending technique is applied to embed the watermark in the video frames. Finally Alpha blending extracting technique and inverse discrete wavelet transform is used to extract the watermark from the watermarked video. The robustness of the proposed method is analyzed by PSNR and MSE values.
