Description: 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B M P位图文件的文件格式, 然后根据 24位真彩色B M P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。-LSB information hiding algorithm use of airspace carrier signal is carried by tuning the lowest bits of the original carrier of information to hide the information. Firstly, a brief description of the BMP bitmap file format, and then based on the particularity of 24 true color BMP bitmap format and display directly change the value of the last bit pixels in the image to embed secret document proposes a text information for effective program encrypted.
