An authentication processing system according to the present invention includes: a wireless terminal which transmits a resident registration number to a service server (wherein, the service server is a server which provides a user authentication and a payment service) with a phone number by receiving the resident registration number from a purchaser through a purchased application; and the service server which transmits an authentication key to the wireless terminal with an message oriented (MO) reception number (wherein, the MO reception number means a reception number to receive a message from a wireless terminal in the MO way) by generating the authentication key if the resident registration number and the phone number are received from the wireless terminal through a communications network. The wireless terminal transmits the authentication key, received from the service server, to the service server in the MO way. The service server determines the purchaser as an active user, if the phone number of a wireless terminal transmitting the authentication key in the MO way and the phone number of a wireless terminal transmitting the resident registration number coincide with each other, and if an authentication key received in the MO way and an authentication key transmitting to the wireless terminal coincide with each other. |
