Abstract: Information hiding based on channel coding is a new field of information hiding technology. This paper presents an information hiding algorithm in channel coding based on m-sequence. It adds an m-sequence to the secret data, and selects the position of secret data in code carrier with m-sequence. The experiment results show that this algorithm has better imperceptibility and robustness.

摘要： 信道编码信息隐藏技术是一门新兴的信息隐藏技术。该文提出了一种基于m序列的信道编码信息隐藏算法。该算法采用m序列对秘密信息进行伪随机加扰，并利用m序列来选取秘密信息在码字载体中的嵌入位置。实验结果表明该隐藏算法具有较好的不可检测性和较高的安全性。
