چکیده مقاله
A novel video watermarking scheme based on chaotic maps and wavelet transform is proposed in this paper The algorithm encrypts a logo image as a watermark signal by bit xor’ing the pixel values of logo and a chaotic map, thus the security of the proposed scheme will be increased In order to enjoy a robust watermarking algorithm, the chaotic watermark signal is embedded into the discrete wavelet transform coefficients of I frames, The investigational results demonstrate that the proposed design can achieve outstanding robustness to common attacks, and it surpasses the existing techniques
