摘要/Abstract

摘要： 混沌同步的发现为有关混沌的保密通讯研究提供了新的拓广空间。本文根据广义混沌同步的基本理论构建了一个新的广义混沌同步系统（GCS）；利用GCS，提出了一个基于小波变换的鲁棒性数字水印算法。数值模拟实例对本文的理论结果进行了验证，理论分析及实验结果表明，给出的数字水印算法对常用的图像处理方法有较好的鲁棒性。

Abstract: The discovery of chaotic synchronization has provided new extending field for the research of the chaos-based secure communication. Based on a constructive theorem for GS systems, a new generalized chaotic synchronization system(GCS)is constructed; Based on GCS, a wavelet-transformation-based algorithm for robustness watermarking is proposed. Experiments demonstrate that the wavelet-transformation-based algorithm is robust against usual methods of image processing.

Key words: generalized chaotic synchronization, digital watermarking , wavelet transform
