Abstract :
The speech information hiding telephone (SITH) is a new steganography scheme based on information hiding security technique system The overall system is designed in embedding method using one fixed point DSP TMS320C54x and three floating DSPs TMS320C31, and a single-chip micro-controller, all DSPs working parallel in speech processing. It is designed for secure and covert communication when speech is transmitted over a public switching telephone network (PSTN).
