摘　　要：探讨了使用M序列作为数字信号方法的优缺点,分析了混沌映射和混沌水印序列的统计特性,在此基础上,对混沌序列数字水印信号与M序列数字水印的性能进行了分析比较,指出混沌序列是最适合作为数字水印信号的序列。The advantage and shortcoming of the method on using M sequence for digital watermark signal is probed on at first, then, the statistical characteristic of chaotic mapping and chaotic-based watermarking sequence is analyzed. Based on these, the performances of chaotic sequence digital watermark signal and M sequence digital watermark signal are compared with, and at last it draws a conclusion that the chaotic sequence is the best sequence for digital watermarking signal.

关 键 词：数字水印 混沌映射 M序列
