Watermarking of video data using integer-to-integer discrete wavelet transform

This paper proposes a novel video watermarking technique to embed a digital watermark in video data using integer-to-integer discrete wavelet transform. The watermark is embedded in the lowest frequency components of each frame. The method exploits features of the human visual system. The watermark can be extracted directly from the decoded video without access to the original video. Experimental results have indicated that the method is robust against MPEG encoding and re-encoding. It is also perceived that the method is effective against statistical attacks.
