摘要 为抵抗YASS隐写分析算法,本文提出一种新的YASS改进算法。该算法首先利用密钥选择不规则的区域,生成一个虚拟的8×8嵌入块;然后根据图像自身特点,提出一种最小化嵌入失真的计算方法,对嵌入块修改后的量化DCT系数进行失真分析,选择失真影响最小的交流DCT系数进行秘密信息嵌入,取代传统方法直观选择前19交流DCT系数。将文中改进算法与虚拟嵌入块YASS(VH-YASS)算法进行了对比实验,实验结果证明,依据嵌入失真由小到大的顺序选择嵌入信道,在抵抗隐写分析和视觉质量方面都优于VH-YASS隐写方法。 This paper proposed a new YASS algorithm to resist steganalysis. Virtual embedding blocks are generated firstly by using a key to select random region. Then a calculation method for minimizing embedding distortion is put forward and the quantized DCT coefficients for embedding the modified block distortion is analyzed. Secret information is embedded by selecting AC DCT coefficients which have the minimum distortion effects, instead of traditional algorithm which selects the first 19 AC DCT coefficients instinctively. The proposed algorithm is compared with VH-YASS algorithm by experiments.The experimental results show that the embedded channel choice based on embedding distortion ascending order is better than VH-YASS steganography methods in terms of resistance steganalysis and visual quality.
