摘　　要：针对秘密信息的安全传输,提出一种信息隐藏算法,将混沌置乱变换及行程压缩编码同时应用于秘密信息预处理,以改善隐藏载体的嵌入容量和鲁棒。该算法将直方图移位技术应用于信息嵌入过程,在绝对矩阵块截断编码(AMBTC)生成的高低平均值序列上隐藏预处理后的秘密信息,实现了载体的无损隐藏并提升了嵌入容量,且嵌入容量高于直接在由AMBTC生成的高低平均值序列上进行隐藏的算法。实验结果表明,在受到某些攻击后仍保证提取出的秘密信息具有较高的可辨识度,归一化系数始终高于0.6,证明了该算法在鲁棒性和隐藏效率方面的优势。因此,提出的信息隐藏方法能达到秘密信息安全传输的目的,同时具有很好的抗攻击性。For the secure transmission of confidential information,this paper proposed an information hiding algorithm.Using chaos scrambling transform and run-length code compression simultaneously in the secret information preprocessing,it improved the embedding capacity and robustness of the stego.In order to achieve the lossless hiding and improve the capacity,it used the histogram-shift technology and the AMBTC(absolute moment block truncating coding)to hide the preprocessed secret information in high and low mean value sequence,and the capacity was larger than that of the algorithm which was only based on the AMBTC.The experimental results show that the extracted secret information can be highly identified even after some attacks,and the normalization coefficient is always lager than 0.6,which proves the advantages of the proposed algorithm in terms of robustness and hiding efficiency.Therefore,the proposed method of information hiding achieves the goal of secure transmission of secret information and has good anti-aggression.
