A detection apparatus extracts an account and a source address of the account from authentication information obtained from an authentication apparatus configured to perform user authentication, groups accounts for each of time slots at predetermined time intervals and each of source addresses in accordance with a timestamp and the source address of the account, and extracts an account group from which duplication of an identical account in an identical group has been excluded. Subsequently, the detection apparatus calculates the number of duplicate accounts among the extracted account groups. The detection apparatus determines that an identical source address is an address of an attacker in a case where the number of account groups of the identical source address in which the number of calculated accounts exceeds a first threshold exceeds a second threshold.

A transferer terminal accesses its account (of the transferer) to receive a list of electronic tickets contained in his account, selects a ticket which is to be transferred, transmits that electronic ticket, an account address of a transferee and a demand for transfer to the account, which in turn accesses an account of a transferee to receive an account addreess certificate, which is then verified by a terminal. A result of verification is transmitted to the account of transferer, whereby the electronic ticket is transmitted from the account of the transferer to the account the transferee. The account of the transferee verifies the received electronic ticket, and upon successful verification, it transmits such result to the account of the transferer, which then demands a certificate of transfer with signature from the transferer terminal. The transferer terminal demands a signature to be attached to the certificate of transfer from a portable processor. The certificate of transfer with signature which is thus obtained is then transmitted to the account of the transferer, which then transmits it to the account of the transferee. The account of the transferee retains the received certificate of transfer with signature together with the electronic ticket.
