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 incre...
