DIGITAL VIDEO SECURITY USING OPTIMIZED AND HYBRID BASED NOVEL WATERMARKING SYSTEM

摘要

Currently large amount of digital information in the form of video, audio or image is available over the internet. So it is to be a great challenge for all researchers to provide security to such a type of digital data. Also the piracy and copyright is emerging issue when digital information is transmitted over the transmission media. So to prevent the problem of piracy, copyright and security of digital data such as video, video watermarking techniques has been introduced. There are various watermarking schemes to give the security to videos but they were unable to provide the quality in terms of imperceptibility and robustness. So we have proposed novel optimized and hybrid based robust digital video watermarking scheme which give the quality and better security to video. The quality of the proposed watermarking scheme is measured in terms of PSNR and NC values. With the use of Genetic Algorithm in the proposed work distinguished the system from existing approaches. The PSNR calculated using our approach is off 55.48 db which is far better than existing approaches. Following invention is described in detail with the help of Figure 3 of sheet 2 showing system architecture of proposed approach module 4 and Figure 3 of sheet 2 showing module 2.
