基于Qt库设计并实现了一个基于静止图像的信息隐藏算法及对应的提取算法。算法以基于空域隐藏算法的最低有效位替换算法为核心思想，为需要隐藏的信息设计了一个特有的格式，以该格式输出的信息作为被隐藏的信息的主体，嵌入到载体图像中，实现了信息隐藏的目的；同时根据信息隐藏的过程，实现了一个信息提取的算法，从而将隐藏信息提取出来。实验结果表明，该算法达到了将文本和文件隐藏到静止图像中的目的。

Its major work is to design and implement an information hiding and extracting algorithm based on static images .The algorithm takes a least significant bits replacement algorithm in Spatial Domain as its core concept .It designs a particular format for the hiding infor-mation ,and the hiding information uses the formatted information as a media of output .By embedding the output into a carrier image ,it fi-nally realizes the ideal of information hiding .According to the hiding procedure ,it also implements an information extracting algorithm which can restore the hiding information .The experimental result reveals that this algorithm achieves the goal of hiding text and files into static images .
