In this paper, we propose a new chaos-based communication scheme using the
observers. The novelty lies in the masking procedure that is employed to hide the
confidential information using the chaotic oscillator. We use a combination of the addition
and inclusion methods to mask the information. The performance of two observers, the
proportional observer (P-observer) and the proportional integral observer (PI-observer) is
compared that are employed as receivers for the proposed communication scheme. We
show that the P-observer is not suitable scheme since it imposes unpractical constraints on
the messages to be transmitted. On the other hand, we show that the PI-observer is the
better solution because it allows greater flexibility in choosing the gains of the observer and
does not impose any unpractical restrictions on the message.
