This paper discusses the digital watermark algorithm based on chaotic system-encrypting and scrambling. In the algorithm, it takes the meaningful binary image with the copyright information as the watermark and encrypts and scrambles the watermark with the chaotic sequences designing the square. It embeds the watermark in the wavelet domain and has better robust. In the experiment, it proved that the algorithm is better.
