| 摘 要： | 研究了数字图像信息隐藏技术,以BMP数字图像为载体,提出把密码信息文件的比特位先与载体图像的最低4位进行比较,结果的成功与否直接影响到信息隐藏的效果。结果表明:载体图像隐藏秘密信息后图像质量的变化非常小,而且秘密信息能从载体图像中完全恢复。

| Abstract: | This paper discussed the information hiding technology based on BMP digital image,and basic LSB.Using the matching principle to determine the hidden location of low four bits in carrier image,and low one bits in carrier image will be replaced if not matching between carrier image and secret information.The simulation results show that the small changes in carrier image after hiding several secret information,and the secret information will be restored completely from carrier image.The algorithm can hide hig... |
