A novel video watermarking algorithm based on chaotic maps in the transform domain

Abstract

A novel video watermarking algorithm based on wavelet transform and chaotic maps is here introduced. We apply the two dimensional wavelet transform on I-frames and then insert the chaotic watermark into part of the sub-band coefficients. Since chaotic maps are sensitive to initial values, initial values of the chaotic maps and their chaotic parameters are exploited as secret keys in our algorithm. Results are presented to reveal the usefulness of the algorithm. Comparisons are made with the latest video watermarking schemes.
