Digital Video Watermarking based on Different Wavelet Transform

Abstract

In one's everyday life, web is developing and turned into an imperative part. Digital content can easily be downloaded, duplicated or altered. Digital content can be secured by number of ways. Digital Watermarking is one of the strategies for the insurance of Digital Content. Digital Watermarking is a plan of copyright protection in which a watermark data is embedded into cover image in such a way that the watermark data is not detected and it is invisible. A watermark will be an intellectual property rights is in the form of image, audio, text, numbers etc emerged into images, video files, audio files and other multimedia data having assured methods, approaches, algorithms. To protect the authentication and authorization rights, different wavelet transform based techniques have been proposed to making the watermarked data more robust, imperceptible and secure. In this work, watermarking has been done using SVD method, and comparison of Discrete wavelet transform (DWT) and Lifting wavelet transform(LWT). The results of the scheme are compared the imperceptibility and the robustness of the video frame, on the basis of the parameters such as, correlation coefficient (CC), peak signal to noise ratio (PSNR) and structural similarity index (SSIM ).
