If the user inputs a setup authentication number after inputting his interest information(403,405), the first mobile terminal transmits the inputted user interest information and the setup authentication number to an information management server together with its present location information(407). The information management server maps the received user interest information onto map information corresponding the received location information together the setup authentication number(409).
