Abstract :

The security and authenticity issues of digital videos are becoming popular than ever, due to the rapid growth of multimedia and Internet technology. On Internet, digital videos are easily and widely shared among the different users at different geographical places. Every day large amount of digital videos are transmitted over the Internet in various applications. As digital technology allows unauthorized reproduction of digital videos, the protection of the copyrights of digital video is a very important issue. Video watermarking schemes are used to protect the digital videos. It is the process of embedding an imperceptible data (watermark) into cover video. The video watermarking schemes have been widely used to solve the copyright protection problems of digital video related to illegal usage or distribution. To resolve the copyright protection problem, it proposes an effective, robust and imperceptible video watermarking scheme. The combination of Discrete Wavelet Transformation (DWT) and Singular Value Decomposition (SVD) of Blue channel is used to embed the watermark. The copy of the watermark is embedded into high frequency subband coefficients which are very difficult to remove or destroy. The combination of DWT and SVD increases the security, robustness and imperceptibility of the scheme. The extracted watermark image will be matched with input logo image for authentication to access (play) the video.
