摘要 本文提出一种JPEG图像的信息隐藏算法,根据给定阈值确定隐藏信息的低频DCT系数,对这些低频系数进行编号分组,得到载体信息.将秘密信息每2位分为一组,每组秘密信息转换为十进制数,用这个数确定隐藏到载体中某组系数的位置.根据嵌入方式,对秘密信息进行预处理得到嵌入数据,通过与3的模数修改隐藏信息的低频DCT系数实现信息隐藏.实验结果表明,本文算法有较好的视觉效果. This paper proposes a steganography scheme based on JPEG images. According to a given threshold, the low frequency coefficients are chosen to hide data. Then these low frequency coefficients are divided into groups to get the carrier. Two bits of secret message are taken as a group from the secret information,and converted into a decimal number. This number will be used to determine the hiding po- sition of the coefficients group. According to the hiding scheme,the secret message is preprocessed to get the hidden data,and the low frequency coefficients of the hiding position is modified by model 3 to hide the secret data. Experimental results indicate that the proposed scheme achieves better image quality of stego-images.
