摘　　要：研究了一种基于LSB的数字图像信息隐藏算法,采用先匹配、若匹配失败再替换的原则,将秘密信息每个字节连续两位依次隐藏于载体图像中每个字节最低四位的两位上。试验结果表明,该算法载体图像隐藏各种秘密信息后图像质量变化小、秘密信息能从载体图像中完全恢复、隐蔽性强,嵌入量大,应用前景广阔。This paper discusses the hidden information technology of digital image based on LSB.The matching principle is used to determine the hidden location of low four bits in carrier image.And low two bits in carrier image will be replaced if not matching between carrier image and secret information.The simulation results show that the small quality changes in carrier image arise after hidden various secret information and the secret information can be restored completely from carrier image;the algorithm has high hidden capacity of data,which will be found wide application in the future.
