ABSTRACT:
An event-ordering certification system100includes a certification apparatus1, a plurality of user apparatuses2i(i=a, b, . . . , n), an audit apparatus3for performing an audit of an event-ordering receipt published by the certification apparatus1and a network4for connecting these elements with each other. In response to an event-ordering request from one user apparatus2i, the certification apparatus1publishes the event-ordering receipt and sends it to the user apparatus2i. If a mistrust is produced in the event-ordering receipt, the user apparatus2iverifies the event-ordering receipt with the use of data published by the certification apparatus1and an audit result by the audit apparatus3.
