Is transmitted to the reception address 56 of the server 3 input to (step S105).

  On the other hand, when the encrypted email is received, the server 3 decrypts the email, and as shown in FIG. 9, the email address and the personal identification document image attached to the email are displayed. The data are linked and stored in the memory 33 (step S106).

  Next, the character recognition unit 35 reads the personal identification document image from the memory 33 and performs character recognition (OCR) processing (step S107), and obtains a character string as a character recognition result.

  Subsequently, the comparison / determination unit 37 refers to the identity verification document dictionary storage unit 36 to determine whether the image is appropriate or inappropriate as evidence of this procedure (step S108).

  That is, the comparison / determination unit 37 determines the sharpness of the image and whether the image is valid as a personal identification document.

  Specifically, the comparison / determination unit 37 compares the character string candidate with the character string by reading from the personal identification document dictionary storage unit 36 and comparing the character recognition result obtained by the character recognition unit 35 with the character string. / Determine the degree of mismatch, that is, the degree of matching between character strings.

  When the matching degree of the character string is higher than a preset threshold, the image is determined to be valid (appropriate, passed, etc.). When the matching degree of the character string is lower than the threshold, the image is invalid (inappropriate, Judgment is made. Note that the threshold is set to 80%, for example. This threshold is an example, and may be another value.

  For the sharpness of the image, the gradation change rate of the image is obtained, and whether or not the focus is changed exceeds a preset threshold value. The result may be determined together with the validity determination result of the image. The two determination results can be combined by, for example, a method of taking a logical product or taking a logical sum.

  As a result of the validity determination of the identity verification document, when the image is appropriate (passed) as evidence (“appropriate” in step S108), as shown in FIG. 1 and FIG. Are stored in the master DB 43 in association with the application information of the contractor already registered in the master DB 43 (step S109).

  At the same time, if the validity determination result of the comparison / determination unit 37 is valid, the reply mail processing unit 41 inserts a standard message indicating that the image has been accepted into the e-mail, and returns the message to the mobile terminal 1 that is the application source. (Step S110).

  On the other hand, if the validity determination result of the comparison / determination unit 37 is not valid, that is, it is rejected (images cannot be accepted), the image and the e-mail address of the e-mail received for each procedure type are temporarily stored in the memory 33. After saving (step S111), the e-mail address temporarily saved in the memory 33 is set in the address field, and a standard message of the reason for failure (a re-acquisition request comment for the identity verification document) is displayed as shown in FIG. The written e-mail is returned to the mobile terminal 1 of the application source (step S112).

  As described above, according to the first embodiment, the application necessary for the procedure for confirming the image of the personal identification document is realized by the web application provided by the web access from the portable terminal 1 to the server 3. Use the camera function to shoot and send identity verification documents. In other words, without using application software downloaded from the network, it is possible to send the image of the personal identification document to the procedure destination and receive the confirmation result.

  This eliminates the need to download the software to the contractor's mobile terminal 1, thereby reducing the costs such as packet communication fees and time required to download the software, and reducing the burden on the contractor who uses the application only once. can do.

More specifically, the procedure is derived from the input contents to the mobile site and the character recognition result of the image sent by e-mail, and it is determined whether the image is appropriate as the image of the identity verification document. If there is, the fact is notified to the mobile terminal 1 of the application, and if it is inappropriate, a re-transmission request is notified. You can verify your identity with the selected image.
Further, according to the first embodiment, the application information which is already input information is searched based on the type of procedure corresponding to the received e-mail or the character information acquired from the image data attached to the e-mail. By specifying the case and linking it, the certainty of the procedure can be ensured.

Furthermore, in this embodiment, by confirming the pass / fail of the entire subject by confirming the gradation change rate in the image, it is easy to see not only the character string but also the part of the picture or photograph (readability). ) Can be confirmed.

  In the case of the fourth embodiment, one of the application buttons 53a to 53c for the desired procedure is pressed from the personal identification document sending screen 51 for application displayed on the mobile terminal 1 (see FIG. 5) (step S401). When there is a request for displaying the outgoing mail creation screen (see FIG. 6), the Web server unit 39 of the server 3 creates and issues a one-time mail address according to a predetermined issuing rule for each type of procedure, A transmission mail creation screen (see FIG. 6) in which the one-time mail address is inserted in the destination field is displayed on the display unit 9 of the mobile terminal 1. The processes after step S102 are the same as those in the first embodiment.

According to the fourth embodiment, by issuing a one-time mail address on a website (mobile site) accessed from the mobile terminal 1, an e-mail has been sent without a subject or text and with an omission of an image attachment. Even in this case, the procedure applied from the mobile terminal 1 can be specified on the server 3 side.
In addition, by using a one-time mail address for data transmission, it is possible to specify a case even if it is an empty mail, and at the same time, it is possible to prevent a malicious third party from using a crime.

  In each of the above-described embodiments, when the image of the personal identification document is transmitted from the mobile terminal 1 to the server 3 by e-mail, the communication fee (packet cost) becomes a burden on the user when the mobile terminal 1 is a mobile phone, for example. .

  Therefore, in order to compensate the packet fee for the user, a mail address mechanism is used in which the recipient pays the packet fee, such as toll-free. Specifically, a mechanism is adopted in which a packet transmission fee to a specific mail address is charged to the recipient side through service cooperation between carriers, or if the procedure is an insurance claim, for example, the packet equivalent is insured It is preferable to add money when paying money.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.

  In the above-described embodiment, the camera-equipped mobile phone is illustrated as an example of the mobile terminal 1, but other than this, for example, a PDA, a tablet terminal, an electronic book terminal, and the like equipped with an Internet connection function and a camera function may be used.

  In the above embodiment, identification information for identifying the type of document is included in a part of the image file name. However, for example, the identification information may be embedded in the image itself as a digital watermark. In this case, since the identification information of the document can be concealed, there is an effect that unauthorized use of the document image can be suppressed.

  Each component shown in the above embodiment may be realized by a program installed in a storage such as a hard disk device of a computer, and the above program is stored in a computer-readable electronic medium: electronic media. The computer may realize the functions of the present invention by causing the computer to read the program from the electronic medium. Examples of the electronic medium include a recording medium such as a CD-ROM, flash memory, and removable media. Further, the configuration may be realized by distributing and storing components in different computers connected via a network, and communicating between computers in which the components are functioning.
