PROBLEM TO BE SOLVED: To make it unnecessary to provide any authentication management ledger or authentication management medium, and to achieve reinforcement in respect of a security aspect. SOLUTION: An application terminal 14 having a portable external storage medium makes the electronic approval application of information output permission application data related to a bringing-out date or a bringing-out time zone (S201), and a third person who has browsed this by a work flow or the like operates an approval terminal 15 to perform approval processing (S202). An information output permission device 10 connected through a communication network to the application terminal 14 and an approval terminal 15 automatically outputs user account information which is made valid only in the bringing-out permission time zone to the application terminal 14 about a bringing-out subject whose approval processing has been performed by the approval terminal 15 (S203, S204). Then, when a log-in request based on the user account information previously output from the application terminal 14 is received, an information output to a portable external storage medium is made valid in a time zone equivalent to output permission time zone information (S205 to S208).
