该技术在水印嵌入时，由混沌系统生成水印序列，并在离散小波变换的低频子带上嵌入水印，保证了水印的鲁棒性。
While embedding watermarking, the watermarking sequences are produced by the chaos system, and are embedded into the low frequent coefficient of DWT domain to guarantee the robustness of watermarking.
同步信号嵌入时域，以提高搜索效率，水印隐藏在离散小波变换域的低频系数中，以达到较好的鲁棒性。
Search efficiency is improved by embedding synchronous signals into time domain. Better robustness is achieved by hiding the watermarking into the low frequency coefficient of DWT domain.
