摘要

An information readout system (100) is provided with an information readout apparatus (110) and an authentication-information generating apparatus (120). An identification-information acquiring section (111) acquires medium-identification information individually assigned to a recording medium (101) on which predetermined information is recorded. An authentication-information acquiring section (112) acquires authentication information generated on bases of medium-identification information and apparatus-identification information individually assigned to itself. A readout section (113) reads out information recorded on the recording medium (101). A readout control section (114) controls the readout section (113) in accordance with the authentication information. A receiving section (121) receives the medium-identification information and the apparatus-identification information from the information readout section (110). A generating section (122) generates authentication information by using the medium-identification information and the apparatus-identification information. A transmitting section (123) transmits the authentication information generated to the information readout apparatus (110).
