摘要

本文基于混沌特性提出一种改进的小波数字水印算法IWSVD

即采用混沌模型算法来生成混沌随机序列.混沌序列{Xn}对初值极为敏感

以此随机序列作水印信息

随机序列不同

会导致生成的数字水印不同

保证数字水印信号的唯一性

因而攻击者伪造水印是不可能的

检测抵赖也是不可能的.迭加了水印的图像能抗压缩及抗噪音处理

该算法健壮性更好.

Abstract

An improved wavelet watermarking algorithm based on chaotic property is proposed.The random sequence acted as watermark is generated using chaotic function model.Since the chaotic random sequence is sensitive to initial value

different random sequence causes different watermark

which makes digital watermark be unique.Therefore it is impossible for an attacker to forge digital watermark and to detect repudiately.The embedded watermark is robust to compression and noise addition etc.
