Abstract
A data transmitting apparatus generates, by using predetermined first key information and information data, a multi-level signal in which a signal level changes so as to be approximately random numbers, and converts the multi-level signal into a modulated signal, in a predetermined modulation method and transfer the same. A data receiving apparatus demodulates the modulated signal so as to be converted into a multi-level signal, and reproduces information data from the multi-level signal, using second key information which has the same content as first key information used by the data transmitting apparatus.
