An authentication processing system according to the present invention includes: a wireless terminal which requests a symmetric key (wherein, the symmetric key is a key for generating a coded message which encodes a resident registration number which is inputted by a purchaser) to a service server (wherein, the service server is a server which provides a service corresponding to a purchased application) by receiving the resident registration number from a purchaser through the application; and the service server which provides a service corresponding to the application and transmits the symmetric key to the wireless terminal by generating the symmetric key if a request for a symmetric key is received from the wireless terminal through a communications network. The wireless terminal generates a coded message which encodes a resident registration number by using the symmetric key received from the service server; and transmits the coded message to the service server in a message oriented (MO) way. The service server judges a purchaser as an active user if the phone number of a wireless terminal transmitting the coded message in the MO way and the phone number of a wireless terminal requesting the symmetric key coincide with each other. |
