An information exchange support apparatus for determining that an exchange condition of information to be exchanged is met between identified exchanging parties and reliably executing exchange of the information to be exchanged between the exchanging parties is provided. An information exchange support apparatus 1 includes reception means 101, exchange determination means 102, transmission means 103, and storage means 104. The reception means 101 receives exchange request information containing the information to be exchanged and information identifying the exchanging party from a terminal. The transmission means 103 transmits the information to be exchanged contained in the received exchange request information to the terminal of the exchanging party. The exchange determination means uses the received exchange request information to determine whether or not information exchange is permitted; the exchange determination means determines that information exchange is permitted at least if the exchange request information from the mutual exchanging parties is already received.
