- LSB密写技术是目前一种应用最为广泛的数据隐藏技术。本文通过对LSB密写算法的分析,指出了对载体图像进行LSB密写会引起图像统计特性改变的原因,并在此基础上提出了一种基于记忆特性的LSB密写算法。该算法记录下载体已经进行密写部分的统计特性,如果被嵌入的秘密比特与原始像素值的最低位相同,就不作改动 否则就根据该统计特性进行增1或减1的调整 在接收方,提取信息时只需要将载体图像的最低比特位提取、解密即可恢复秘密信息。该算法具有较高的隐蔽性,能够有效地抵抗统计分析方法。-Steganography i

- 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提取秘密信息.-In order to provide la
