- mylsb.m是个非常完整的LSB密写源码并且密写和提取都在里面,图片我没上传,你只需要添加一个图片文件就可以了,记住图片必须是灰度图片,如果是RGB,我转换的代码也在里面很有意思哦。weipingmian.m是个提取图像位平面的程序,图片也是需要你自己加载,最后一个就是8*8块的图像DCT变换。-mylsb.m is a very complete source of LSB Steganography Steganography and extraction, and are on the

JSTEG
- Jsteg隐写算法[23][24]由D. Upham提出,该算法将秘密信息嵌入在量化后的DCT系数的LSB上,但值为-1、0、+1的DCT系数例外。提取秘密信息时,也只是将隐藏信息的图像中不等于-1、0、+1的量化DCT系数的LSB取出即可-steganography of jsteg

Jsteg
- Jsteg算法实现,Jsteg是一种基于JPEG的常用信息隐藏算法步骤如下: 首先,把掩体图像分为不重叠的8*8的子块,对每一子块进行DCT并对变换得到的DCT系数进行量化 其次,将待隐藏的信息进行加密,将加密结果嵌入到量化后值不为0,1或-1的DCT系数的最 低有效位(LSB)中,其嵌入顺序是按zigzag扫描顺序进行的。最后,用JPEG的嫡编码(包括哈夫曼编码,游程编码及DPCM)对嵌入秘密信息后的每一子块进行编码,从而得到一个含有秘密信息的JPEG stego文件。-Jsteg
