Design of information hiding in audio for mobile communication system based on energy ratio adjust algorithm

In order to design secret information hiding for public mobile communication system, this paper detailed analyzes the software and hardware solution of information hiding in Audio for mobile communication system. A speech hiding algorithm based on energy ratio adjust is presented. The hearing similarity, robustness and computational complexity of the whole system are tested and analyzed. Test results show that the confidential information can be transmitted covertly through the system.
