A Robust Video Watermarking Algorithm

Abstract

Problem statement: Video watermarking is well known as the process of embedding copyright information in video bit streams. It had been proposed in recent years to solve the problem of illegal manipulation and distribution of digital video. Approach: In this study, an effective, robust and imperceptible video watermarking algorithm was proposed. This algorithm was based on a cascade of two powerful mathematical transforms; Discrete Wavelets Transform (DWT) and Singular Value Decomposition (SVD). Two different transform domain techniques showed high level of complementary and different levels of robustness against the same attack will be achieved through their combination. Results: The proposed algorithm was tested against imperceptibility and robustness and excellent results were obtained. Conclusion: Experimental results demonstrate the robustness achieved by combining the two transforms.
