A Hybrid Approach for Video Watermarking Using DWT and SVD

Digital data is being created every day and spread across the internet. Since the data is on the internet, it can be accessed and misused by anyone who has access to the internet. Even with encryption technique, when distributed it can be easily decrypted and modified to the persons needs. The problem can be addressed by embedding the information into image, audio, and video using digital watermarking technique. The embedded information can be later retrieved and used for identification and authentication purposes. The challenging task in watermarking is illegal distribution and handling of digital video is turning out. It can be solved by embedding copyright information into bit streams of any video. In recent research, image watermarking technique in which digital images can be embedded with a code. It is done is such a way to ensure non-erasability of the image watermarking. While it ensures non-erasability, it does introduce Gaussian noise during the process of watermarking, the contrast and brightness of the hidden image will be affected due to the watermarking of information and also the entire image consumes a lot of memory after the entire watermarking procedure is done. In this paper, a hybrid approach for watermarking is proposed and tested which incorporates FT (Framelet Transform), PCA (Principal Component Analysis) and SVD (Singular Value Decomposition). The model is robustness against watermarking attacks, imperceptibility, capacity and security.
