On the second page 500b, accumulated point information, an OCR entry field 520 for mail order application, and some two-dimensional codes are printed.

Here, the OCR column 520 includes three two-dimensional codes 510a / b / c. By capturing three two-dimensional codes at the corner of the field of view of the camera of the mobile terminal device 100 and photographing the OCR field 520, OCR image data with an accurate angle of view can be created. That is, the camera stores the two-dimensional code 510a and the two-dimensional code 510b at the corners of the diagonal position of the field of view, and in addition, stores the two-dimensional code 510c at the corners of the field of view. Can be directly opposed. Further, since the two-dimensional code 510a and the two-dimensional code 510c are stored in the corners of the camera field of view, the OCR column 520 is photographed without tilting. As a result, the characters entered in the OCR column 520 can obtain a result of high OCR recognition accuracy.

Note that on the page with the OCR entry column, only the user information (= personal information) of the two-dimensional code is described, and the user information in plain text is not described. Therefore, the personal information of the user does not leak from the OCR image.

FIG. 7 is a diagram for explaining an authentication processing procedure. The two-dimensional code 510 of the specification is photographed, and the information “http://www.dnp-credit.co.jp/apl#url.cgi id = xxxxxxx” including the connection permission ID is decrypted (FIG. 7 (1 )).

To this, the user's mobile phone number “090-1234-5678” is added, and the application URL 197 “http://www.dnp-credit.co.jp/apl#url.cgi id = xxxxxxx no = 090-1234 -5678 "((2)).

The user ID corresponding to the telephone number of the application URL 197 and the connection permission ID is selected from the correspondence table 391 and authenticated ((3).

In this way, only applications from the mobile phone 100 registered in advance by the user are accepted. Even if another person makes an application from the unregistered mobile phone 100 using the picked-up application form, it is not authenticated.

As described above in detail, according to the present invention, information leakage can be prevented by converting the customer's personal information (customer name and customer number) into a two-dimensional code. In addition, since the information of the destination to which the information is transmitted can be obtained by decoding the two-dimensional code, it is possible to prevent the information from being transmitted to the wrong destination by using this information.
