Abstract
This paper explains the work to design an information hiding based secure communication system, named covert speech telephone (CST). The overall system is designed over the internet using UDP protocol. Based on a GUI (graphical user interface) software, CST is possible to execute two optional secure modes. It is a completely digital system with high speech quality. Practical effects show that CST can meet the requirement of real-time secure communication. This new technique can effectively guarantee information security in VoIP system.
