摘　　要：首先介绍BMP文件结构及特点以及相邻像素相关的特性，基于此提出了一种新的隐写分析算法，该算法分别计算每个像素与其八个领域像素的异或值的和，再统计根据计算的值归类，以此扫描完成整个图像。最后统计图像中各个异或值和相同的数目，以此来判断是否含有隐秘信息。实验编程环境为VS2008，通过实验结果表明，此检测算法统计量小、实现简单，在隐秘信息嵌入量较多时具有较高检测率。At first, it introduced the structure, the characteristics and the related properties adjacent pixels of the BMP file, it put forward a new steganalysis algorithm based on this. This algorithm calculates each pixel and its eight-pixel areas of the XOR val-ue’s sum, then it Statistics calculated and classified, in order to complete the scan image. Finally, that statistical each image XOR value and the same number, in order to determine whether it contains secret information. This experimental programming envi-ronment is VS2008. This experimental results show that, this detection algorithm is a small amount of statistic and simple, it has high detection rate when more secret information is embedded.
