Dual Watermarking in Video Using Discrete Wavelet Transform

The proposed system in this paper gives the invisible watermarking which is performed by using Discrete Wavelet Transform. To get the invisible watermarking the alternate pixel value of the host video is replaced by the pixel value of watermark video/image. This type of watermarking provides a means of forensic analysis for combating media piracy. Video watermarking provides robustness to geometric attack such as rotation, cropping, contract altercation, time editing without compromising the security of the watermark.
