基于LSB的图像中数据加密隐藏算法程序
图像的组成无非是一些字符串或者一些字节组成的字符串,然而,每一个字节数据位的重要度并不是一样的,两个相邻字节往往只有低位是不一样的。例如:00100110和00100111代表了两个不同渐变度的红色,但是就人眼是分辨不出来的。最低有效位LSB算法,就是利用这一点,达到图像压缩,或者数字水印的功能。
信息隐藏,即将信息嵌入某些载体,而使信息窃取者注意不到信息的存在。由于人眼的视觉的冗余及图像文件本身的数据量很大,数字图像文件是信息隐藏很好的载体,将需要保密的信…
包括的文件有:
findtext.m, hidetext.m, main.bmp, new2.bmp, message.txt, output.txt, gui.fig, new.bmp, gui.asv, gui.p, secret.bmp, read me.txt, screenshot.bmp, screenshot.jpg-err

My stuff is aimed at teaching, not efficiency. The others are probably much better implementations. The last one has both C++ and Java versions where my stuff is all C.
So lots of choices!
