a login receiving module, which receives an account login request from a user terminal device along with account identification information and authentication information; an authentication processing module, which determines whether or not the combination of the account identification information and the authentication information received by the login receiving module matches a pre-stored combination of predetermined account identification information and authentication information, and, in the event of a match, authenticates said user terminal device; a fraud determination module, which detects fraud in the login request from the user terminal device based on the access history of the user terminal device; and a response control module, which allows the user of the said user terminal device to log in to the predetermined account if the fraud determination module does not detect fraud in the login request from the user terminal device and the authentication processing module has authenticated the user terminal device, allows the user of said user terminal device to log in to a dummy account in accordance with predetermined criteria if the fraud determination module detects fraud in the login request from the user terminal device and the authentication processing module was unable to authenticate the user terminal device, and does not allow said user terminal device to log in to the predetermined account or the dummy account and delivers an error notification to said user terminal device if the fraud determination module detects fraud in the login request from the user terminal device and the authentication processing module has authenticated the user terminal device.
