一种容错文本信息隐藏算法

A fault-tolerant algorithm for text information hiding

结合数字通信信道容错设计和文本信息的特殊性,提出了一种结合容错设计的纠错编码的新型信息隐藏算法。在嵌入信息预处理的时候结合数字通信中的信号编码理论和方法,并且加入复合混沌加密系统来改善系统的稳健性。并且在常见的变换域隐藏算法的基础上提出多频带隐藏和重复隐藏。在增大隐藏信息量的同时,提高了抵抗常规攻击的能力,具有较强的鲁棒性。

In this paper,fault-tolerant design of digital communication channels and text messages made the particularity of a combination of fault-tolerant design of error-correcting coding new information hiding algorithm.In a time when the pre-combination of embedded information in digital communication theory and method of signal coding and joined the compound chaotic encryption systems to improve the system robustness,and in the common transform domain hiding algorithm based on the multi-band hidden,and repeat hiding.It can increase the amount of information hidden,in the same time it also can increase the capacity of resistance to conventional attack,so it has strong robustness.
