Abstract

Digital Watermarking is a method or technology that hides information in to a digital media. It is a two way process which involves embedding and extraction. Video watermarking technique is somehow similar to image watermarking. This mechanism is used to overcome the problem of security, copyright and content authentication of the digital media. The objective of this scheme is to create a watermarking system to make a video more secure. In this paper, we proposed a digital video watermarking technique with multi-level discrete 3-D wavelet transform using MATLAB. In the proposed method, first the video frames are extracted from the host video. Then, each frame get watermarked with multi-level discrete 3- D wavelet transform using key which is also known as embedding. After that each watermarked video frame get reconstructed. Watermarked video is obtained after reconstruction of watermarked video frame. The effectiveness of frame is evaluated using frame quality measures against some attacks.
