Zusammenfassung:	ABSTRACT A system of transmitting an information individually and secretly is disclosed. The informa-tion to be transmitted is converted, on the transmisssion side, in accordance with a predetermined algorithm designated by two keys and then transmitted to a receiv-ing side. The receiving side is supplied with at least two keys from the transmitting side for reproducing a transmitted information by using the two keys. One of the keys is frequently changed so that the algorithm is also changed frequently. Accordingly, even if non-contracted receiver gets hardware for converting the information it cannot receive the transmitted information.
