Based Fractal Modulation Array Digital Watermarking Algorithm

With the booming development of information industry, thedigitalization of information media and the exceptional growing of computer networks, we can get digital information conveniently and quickly. But the negative effect of digitalization technology has made the copyright and security of digital information products be widely threatened now. In the open computer network environment, it has become much urgent for us to provide efficient copyright and security protection means for the digital information products. So the digital watermarking technology has been put forward for this in recent years.In this paper, We present a novel HVS-based visual masking image watermarking using fractal modulation array, because of the good performance of fractal modulation. In this algorithm, fractal modulation array is embedded to the middle frequency coefficients of the block-DCT; then visual masking is made. The simulation results show that we can remarkably extract the hiding watermarking and watermark can achieve better robust with common signal distortion or geometric distortion.
