  When the user operates the display unit 7 of the ATM 100 and selects “screen information transfer by the camera 6” (not shown) of the ATM 100, the CPU 32 of the ATM 100 activates the camera module 36 (step S05).

  In this case, the CPU 32 of the ATM 100 activates the camera module 36, the encryption key generation unit 110 generates the public key 200, and the public key display unit 120 converts the identifier of the public key 200 into, for example, a two-dimensional barcode. And it displays on the display part 7 (step S07).

  Then, the user faces the camera 2 of the portable information terminal 1 to the display unit 7 of the ATM 100 and operates the button 10, whereby the portable information terminal 1 is displayed on the public key 200 displayed with a two-dimensional barcode. Get an identifier.

  The portable information terminal 1 acquires the identifier of the public key 200 displayed by the two-dimensional barcode from the image displayed on the display unit 7 and stores the identifier of the public key 200 in the RAM 15.

  Then, the CPU 12 extracts the public key 200 from the stored identifier of the public key 200, and performs encryption processing on the ATM input information displayed on the display unit 3 using the public key 200.

  Then, the CPU 12 converts the encrypted ATM input information into, for example, a two-dimensional barcode and displays it on the display unit 3 using the external display module 13.

  As described above, the portable information terminal 1 can encrypt the ATM input information with the public key 200 and convert the ATM input information into a two-dimensional barcode, and display the encrypted ATM input information on the display unit 3.

  Then, the user causes the display unit 3 of the portable information terminal 1 to face the camera 100 of the ATM 100 and causes the camera 6 of the ATM 100 to read the encrypted ATM input information.

  The ATM 100 captures the encrypted two-dimensional barcode image displayed on the display unit 3 of the portable information terminal 1 from the image reading unit 130 by the camera 6 and writes it in the RAM 35 (step S09).

  Thereby, the ATM 100 can display the public key 200 on the portable information terminal 1.

  In step S <b> 25, the ATM 100 uses the camera 6 to obtain encrypted ATM input information displayed on the display unit 3 of the portable information terminal 1. As described above, in the ATM 100, by using the camera 6, the image reading unit 130 can acquire a display image.

  In step S27, the ATM 100 awaits confirmation for performing transaction processing from the user, and in the first transaction processing, the user confirms the display unit 7 of the ATM 100, for example, “transaction information has this content. Confirm the transaction details with a message such as "Is it OK?"

  Then, for example, when the user presses a button such as “perform transaction” (YES in step S27), the ATM information control unit 150 determines that the transaction information is correct.

  In the present embodiment, in the second and subsequent transactions, the transaction history that has been processed in the past is referred to. If there is a transaction history (YES in step S27), the transaction information is correct. The transaction processing unit 160 can perform predetermined transaction processing.

  On the other hand, even for the second and subsequent transactions, the transaction history that has been processed in the past is referred to. If there is no transaction history (NO in step S27), it is determined that the transaction information is not correct, and step S21 It will return to.

  Thus, in this embodiment, the ATM 100 generates the public key 200 on the spot, displays the identifier of the public key 200 on the screen, and the user captures the identifier with the camera 2 of the portable information terminal 1. It is like that.

  As a result, in this embodiment, the portable information terminal 1 encrypts the ATM input information using the public key 200, and the camera 6 of the ATM 100 takes in the encrypted ATM input information. Therefore, the user can dramatically improve confidentiality simply by performing a simple operation.

  As described above, according to the present embodiment, the portable information terminal 1 encrypts the ATM input information using the public key 200, and the camera 6 of the ATM 100 captures the encrypted ATM input information. As a result, the user can easily perform transaction processing without any mistakes by performing simple operations.

  Further, according to the present embodiment, the information processing system can improve confidentiality because the ATM 100 generates the public key 200 and performs encryption and decryption based on the public key 200. .

  As mentioned above, although embodiment of this invention was described with reference to drawings, these are the illustrations of this invention, Various structures other than the above are also employable.
