摘要
首先分析了BMP图像文件格式,然后根据传统LSB算法在BMP图像文件中应用,提出一种改进的LSB隐藏算法,提高了伪装图像质量。最后通过仿真验证了该算法的优越性。
In this paper the format of bitmap file is analyzed, and then an improved algorithm based on least - significant - bit substitution （LSB） which is applied in BMP file is presented. Compared with the traditional LSB algorithm, the quality of the stego - image is greatly improved by applying the new algorithm. At last the experiment shows the algorithm is advantage.
