Abstract: This paper proposes one kind of design and implementation of a steganography system based on the picture, introduces the application program realization plan, produces the system composition block diagram. A new transmission method of the Chinese character text information based on the picture solves the communication security problem of the information transmission at Internet. The practice indicates the system has the promotion and the application value.

Key words: Steganography, Information hiding, Picture
