Abstract :
This paper discussed the model and realization strategy of information hiding and encryption in secret telephone communication, and presented a novel information hiding and pickup method based on DCT. A mode switcher was used to let the system have the same process procedure for secret and non-secret communication. The system proposed in the paper had advantages such as high safety, real time, extensible and so on. It is a new effective approach of secret speech communication
