Research on the Anti-attack Characteristics of Different Wavelet Base Information Hiding Algorithm

为了分析DWT图像信息隐藏算法的抗攻击特性,对不同的小波基信息隐藏算法的抗攻击性进行比较研究,在嵌入容量相同的情况下,分别用椒盐噪声攻击、压缩攻击、裁减攻击、线性滤波攻击,对基于coif1、db1、haar和Sym1四种小波基的信息隐藏算法进行实验。得到相关有益的结果,可对算法设计和优化提供参考。

In order to analyze the anti-attack characteristics of DWT image information hiding algorithms, the anti-attack characteristics of different wavelet base information hiding algorithms are compared and studied. Under the same embedded capacity, the salt and pepper noise attack, compression attack, linear filtering attack, and cropping attack are used to carry out experiments with coifl, dbl, haar, and Syml, four kinds of wavelet base information hiding algorithms, respectively. The relevant beneficial results are obtained, and can provide helpful reference for the algorithm design and optimization.
