Analysis and Implementation of IWT-SVD Scheme for Video Steganography

In the world of computer, the skill of sending and displaying secret data particularly in public places faced several challenges and had received more attention now. Protecting information on communication media is a vital need in information transmission technology. We can protect information through encryption process over the transmission media but due to advanced computing techniques, encrypted information can easily be detected and decrypted. So, for avoiding the unauthorized user from accessing information, we need some more advanced techniques. For this purpose, we use steganography which is a technique to conceal secret message over communication networks. In this paper, IWT-SVD scheme is proposed to conceal watermark image in video cover file. Concealing watermark in video cover file gives higher concealing capacity. It has been shown that concealing watermark in HH and LL sub-band results in good perceptual quality, more robustness, and less computational cost. Simulation results also show that this new scheme outperforms adaptive steganography based on IWT-SVD in term of PSNR, MSE, and concealing capacity.
