利用LSB算法进行信息隐藏的C语言实现

Use LSB Algorithm Implementation Information Hidden in C Language

LSB的含义是(least significant bit)最不重要位。利用LSB算法进行信息隐藏是在载体信号的空域进行的,它通过调整原始载体信息的最低几位来隐藏信息。文章首先简单叙述了BMP位图文件的文件格式,然后根据24位真彩色BMP位图格式与显示方式的特殊性,直接改变图像中像素的最后一位值来嵌入秘密文件,提出了一种对文字信息进行加密的有效方案。

The meaning of LSB is least significant bit. LSB algorithm using information hidden in an air carrier signal, by adjusting its original vector information to the minimum number of hidden information. This paper first describes the simple bitmap file BMP file formats, then 24 true color bitmap BMP format and display the unique characteristics of the image pixels directly change the final value embedded in a secret document, a information is encrypted on the text of an effective programme.
