Abstract :
In this paper, we emphasized on the transform domain method for the digital watermarking of video for embedding invisible watermarks behind the video. It is used for the copyright protection as well as proof of ownership. In this paper we have specifically used the characteristics of 2-D Discrete wavelet Transform and discrete cosine transform for the watermarking. In this work we first extracted the frames from the video and then used Frequency domain characteristics of the frames for watermarking. We calculated different parameters for the sake of comparison between the two methods.
