摘　　要：以载体信息每个字节的最高为1的位为标志位,通过对嵌入信息的数值进行调整,使隐秘信息的嵌入过程对原图像的改变较少,同时保证载体信息的标志位不必变,达到对嵌入信息无损提取。实验结果表明,算法对载体图像的改动小,提高了隐藏容量。The maximum of 1 bits in each byte of the carrier information is considered as the flag bit.By adjusting the value of the embedded information,the process of inserting the secret information changes the original host image less,and guarantees the flag bit of the carrier information does not need to change so that extracting hidden information is completely blind extracting.The experimental result indicates that the proposed algorithm improves the hidden information capacity and the original host image is modified less.
