Robust and Secure Video Watermarking Based on Cellular Automata and Singular Value Decomposition for Copyright Protection

In recent years, watermarking techniques have been under deliberation for their wide variety of applications in various fields. An organization transmits its data through digital communication channels, where the probability of attack is more. To protect the data transmitted through the channel, a novel fuzzy-based digital video watermarking scheme based on Cellular Automata Transform and Singular Value Decomposition (SVD) for copyright protection is proposed. The proposed scheme adopts a mixture of both cellular automata and SVD, which provides copyright protection with high robustness and imperceptibility for multiple transform planes with high processing speed and data redundancy. Moreover, the confidentiality of the proposed scheme is improved with the help of SVD. The watermarked video is experimented with to prove the strength by extracting the watermark image after applying geometric transformation, noise addition, enhancement, and compression attacks. The quantitative performance analysis, which shows improved robustness and imperceptibility of the proposed method compared to the existing methods, is performed by calculating the peak signal-to-noise ratio, structural similarity index, bit error rate, and normalized cross-correlation.
