<P>PROBLEM TO BE SOLVED: To provide a personal identification system which requires no transmission and improves the capability of securing the validity of personal identification. <P>SOLUTION: A mobile communication terminal 1, a provider side server 2, and a card processing server 3 connected for communication through a network 100 are provided. The mobile communication terminal 1 comprises a non-contact IC card in which a mobile phone number, an effective flag representing validity of it, and a card number can be stored. The provider side server 2 stores the mobile phone number and the effective flag, and sends back the effective flag in response to a predetermined authentication request added with the mobile phone number. The card processing server 3 communicates with the mobile communication terminal 1 in a non-contact manner to acquire the mobile phone number, the effective flag, and the card number. The provider side server 2 can be requested for the authentication of the validity of the mobile phone number as required. Only through non-contact communication with the mobile communication terminal 1, or with assistance from the provider side server 2, personal identification can be performed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
