An Adaptive Video Watermarking Based on Secret Image Sharing

Secret image sharing is introduced into the scheme of watermark generation in this paper, secret image sharing can reduce the amount of information bits substantially that embedded into video cover while guaranteeing the watermarking authentication. Base on this scheme a blind video watermarking algorithm for copyright protection is proposed, the value of the selected coefficient is modified adaptively according to the energy value of neighboring coefficients and the binary watermark bits. Experimental data show that the proposed algorithm improves the watermarking robustness against some common signal processing attacks liking salt-pepper noise and re-compression while maintaining the high video quality.
