1. A communication apparatus using a human body as a medium, comprising:
- transmitting means for transmitting secure data signals to the inside of the human body and normal data signals to the outside of the human body through at least two different frequency channels classified according to a predetermined reference value to use a frequency based on a physical characteristic of a channel and increase a data transmission rate while maintaining security; and
receiving means for receiving the secure data signals transmitted through the conductive effect of the human body and the normal data signals transmitted through the radiation effect of the human body.
