A service server can be operated in a more practical rate structure by extending the storage period and/or reducing the recording fee for information having a high utilization factor, or increasing the recording fee for information with a low utilization factor among the information stored in the service server. The service server includes a receiving device which receives the image information from a communication device on the information supplier side and records a recording fee of the received information, a transmitting and receiving device which transmits the information recorded in the recording device to a communication device on the information demander side upon an information service request from the information demander side, a counting device (information processing device) which counts an information service number from the information demander side, a recording device which records the counted information service number to be associated with the information supplier, and a recording fee calculating device (information processing device) which calculates a recording fee by reducing or increasing the recording fee recorded in the recording device. |
