PROBLEM TO BE SOLVED: To provide an information communication system which surely protects privacy of participants and realizes efficient information communication that is made suitable to the situation. SOLUTION: A transmitting terminal 120(i) transmits arbitrary information and authentication information to authenticate the arbitrary information to a control terminal 130 (a step S301). The terminal 130 confirms the fact that the information and the authentication information from the terminal 120(i) are consistent with each other, generates authentication information generating information so that a receiving terminal 120(j) generates the authentication information and distributes the authentication information generating information and the information and the authentication information on the terminal 120(i) to the terminal 120(j) (a step S302j).
