- 由于通过RS统计分析和Chi-squate统计分析,可以察觉以LSB方法密写的秘密信息的存在,因此为提高密写方案的安全性,提出了一种改进的LSB密写方案,即如果被嵌入的秘密比特与原始灰度的最低位相同,便不作改动 否则根据周围像素作增1或减1的调整,而在接收方,只需将载体图象的最低位取出即可恢复秘密信息.大量图象的模拟实验结果说明,该方案不仅可以抵抗RS分析和Chi-square分析,而且不增加失真度,并可保持计算量小、提取方便的优点.并

- 为了提供较大的秘密信息嵌入量和保持良好的载密图像质量,依据人眼对变换剧烈及较暗区域均不敏感的视觉特点,提出了一种基于小波对比度和最低比特位替换(LSB)的图像密写方法.该方法先将载体图像分成固定大小的小块,对每一小块进行小波分解后计算小波对比度.然后,根据该块小波对比度绝对值之和确定该块可以嵌入的位平面层数.最后,采用LSB密写技术逐层嵌入秘密信息.实验结果表明,该密写方法能嵌入较多的信息和保持良好的载密图像质量,并且可直接从载密图像中

- 密写编码技术以占用较多的载体数据为代价来减少对载体数据的修改量,从而降低信息隐藏引起的失 真. 本文首先将密写编码方法的构造转化为一个数据的稀疏表示问题,然后提出密写编码构造算法. 利用该构造算法 可得到一系列密写编码方法,并进一步研究密写编码的组合形式,在不同占用率条件下获得了良好的编码性能,优于 矩阵密写编码和游动密写编码.-Steganographic Encoding Ba sed on Sparse Repre
