The operation of the above-described configuration will be described in accordance with steps represented by S in the drawing of the explanatory diagram showing the flow of processing of the seal stamp inquiry system in the second embodiment of FIG.

S11: The image photographing means 11 of the portable terminal 1 photographs the stamped surface (the surface on which the stamp is made) of the seal 31 by the operation of the customer. Moreover, the customer identification information input means 12 of the portable terminal 1 accepts the input of an account number and a personal identification number as customer identification information by a customer operation.
The control unit 16 of the portable terminal 1 stores the image data of the stamped surface of the stamp 31 taken as the seal image 236 in the storage unit 15, and stores the input account number and password as the account number 231 and the password encryption 232. Store in the unit 15.

S12: When the account number 231, the password encryption 232, and the seal image 236 are stored in the storage unit 15, the WEB site communication means 13 of the control unit 16 stores the account number 231, the password encryption 232, and the seal image stored in the storage unit 15. Information 23 for requesting an inquiry as to whether or not the seal image 236 is a registered seal is transmitted to the inquiry service processing means 2 together with 236.
The inquiry service processing means 2 searches a customer information database (not shown) based on the received account number 231 to extract a registered password, and compares the password with the received password 232 to confirm that they match. Confirm your identity. As a result, when the personal identification number matches and it can be confirmed that the customer is the principal, the inquiry service processing means 2 transmits the received seal image 236 to the seal image processing means 7, and the seal image processing means 7 receives the received seal stamp. A seal image 237 is generated by performing a process of inverting the left and right with the center line in the left and right direction of the image 236 being symmetrical, and a process of cutting out a seal part from the seal image with the left and right inverted.

S13: Furthermore, the seal image processing means 7 generates a red signal from a red signal component (R signal component), a green signal component (G signal component), and a blue signal component (B signal component) as color signal components from the generated seal image 237. A process for extracting and removing only the component (R signal component) is performed, and a seal image 238 for collation is generated.
When the seal image 238 is generated, the seal image processing unit 7 transmits the seal image 238 to the verification unit 4. At this time, the verification unit 4 receives the account number 231 from the inquiry service processing unit 2. The account number 231 may be received from the inquiry service processing means 2 via the seal image processing means 7.

  S14: The verification unit 4 searches the registered seal image database 5 based on the account number 231 to extract the registered seal image 51 of the customer, and collates the registered seal image 51 with the generated seal image 238 for verification. , It is determined whether or not they match. The process of matching the registered seal image 51 and the verification seal image 238 is performed using a known verification process. When the degree of matching exceeds a predetermined threshold, the verification seal image 238 is registered. Assume that it matches the imprint image 51.

S15: The matching unit 4 transmits the determined result to the inquiry service processing unit 2 as a determination result notification 24.
S16: The inquiry service processing means 2 transmits to the portable terminal 1 that the photographed seal 31 as the determination result matches or does not match the registered seal stamp based on the received determination result notification 24. .

The portable terminal 1 displays the received determination result on the display means 14 and notifies the customer to that effect.
In this way, the seal image taken with the mobile terminal possessed by the customer is compared with the seal image of the registered seal registered in the registered seal image database of the financial institution, and only the verification result is displayed on the mobile terminal to notify the customer. Since the seal image of the registered customer's seal is not displayed on the mobile terminal, even if the customer's customer identification information and password are leaked to a third party, the customer's seal is forged Can be prevented.

In addition, safety can be ensured since the inquiry of the registered seal cannot be made unless there is a seal at hand.
Furthermore, since the seal image of the registered customer's registered seal is not displayed on the mobile terminal, the mobile phone terminal having a low-resolution display means can receive the service of this seal stamp inquiry system.

Further, since a seal image is used, it is not necessary to prepare a seal image.
As described above, in the second embodiment, in addition to the effects of the first embodiment, since the seal image is taken, there is an effect that it is not necessary to prepare a seal image.

The configuration of the third embodiment is different from the processing of the image data of the seal stamp taken by the portable terminal 1 performed by the seal stamp image processing means 7, and the other configuration is the same as the configuration of the second embodiment. The same reference numerals are given and the description thereof is omitted.
The image processing means 7 of the third embodiment will be described with reference to FIGS.
In FIG. 3, reference numeral 7 denotes a seal image processing means, which performs a process for removing the background other than the seal of the image data of the seal stamp received from the inquiry service processing means 2, a process for inverting the left and right of the image data from which the background is removed, and the like. A computer such as a server.

Here, the process of removing the background other than the seal of the image data of the seal will be described based on the explanatory diagram of the seal image extraction process in the third embodiment of FIG.
In FIG. 5, 41, 42, and 43 are seal images obtained by dividing a seal image (the seal image 236 in FIG. 4), which is image data of a seal stamp imaged by the image capturing means 11 of the mobile terminal 1, into RGB signal components. The seal image 41 indicates the output of the red signal component (R signal component), the seal image 42 indicates the output of the green signal component (G signal component), and the seal image 43 indicates the output of the blue signal component (B signal component).

As shown in FIG. 5, the seal image 41, the seal image 42, and the seal image 43 are composed of the seal and the hand of the photographer and the background. For convenience of explanation, it is assumed that the background of the seal image is gray.
As shown in the seal image 41 in FIG. 5, the output of the red signal component is increased and the brightness is increased due to the dropout effect in the peripheral portion of the stamp where the vermilion of the seal adheres. In addition, the output of the red signal component is lower in the photographer's hand than in the peripheral portion of the stamp where the seal vermilion adheres, but the output of the red signal component is higher than in the other gray background portions.

On the other hand, the green signal component output and the blue signal component output of the peripheral portion of the stamp to which the vermilion of the seal adheres are the complementary colors of the red color of green and blue, so the red signal component as shown in the seal image 42 and the seal image 43 Lower than the output of. Note that the photographer's hand portion and the background portion are nearly achromatic, so the output is almost the same level as the red signal component.
The processing described below is performed using such features to remove the photographer's hand portion and the background portion, and generate a seal image in which the peripheral portion of the stamp to which the vermilion of the seal sticks is extracted.

From the output value (R) of the red signal component, the output value (R− () is obtained by adding the output value (G) of the green signal component and the output value (B) of the blue signal component and subtracting the output value divided by 2. A seal image of (G + B) / 2)) is generated.
In the peripheral portion of the stamp where the vermilion of the seal sticks, the output value (R) of the red signal component is larger than the output value (G) of the green signal component and the output value (B) of the blue signal component (R >> G , B), and the output value (R) of the red signal component, the output value (G) of the green signal component, and the output value (B) of the blue signal component are approximately the same level in the hand and background of the photographer. Output value (R≈G≈B).

Therefore, the output value (R) obtained by adding the output value (G) of the green signal component and the output value (B) of the blue signal component and subtracting the output value divided by 2 from the output value (R) of the red signal component. -((G + B) / 2)) becomes larger in the peripheral portion of the stamp where the seal vermilion adheres, and becomes smaller (almost "0") in the photographer's hand and background.
In this way, as shown in FIG. 5, a seal image 44 having a large output value is generated in the peripheral portion of the stamp to which the vermilion of the seal is attached.

Further, the left and right sides are reversed with the center line in the left-right direction of the generated seal image 44 being symmetrical, and the seal image 44 is generated.
The seal image processing means 7 generates a seal image 44 to be compared with the registered seal image data of the registered seal by performing a process of removing the background other than the seal of the seal image data described above.
The operation of the above-described configuration will be described according to the steps indicated by S in the drawing using the explanatory diagram showing the processing flow of the seal stamp inquiry system in FIG.

S11: Since it is similar to the second embodiment, its description is omitted.
S12: When the account number 231, the password encryption 232, and the seal image 236 are stored in the storage unit 15, the WEB site communication means 13 of the control unit 16 stores the account number 231, the password encryption 232, and the seal image stored in the storage unit 15. Information 23 for requesting an inquiry as to whether or not the seal image 236 is a registered seal is transmitted to the inquiry service processing means 2 together with 236.

  The inquiry service processing means 2 searches a customer information database (not shown) based on the received account number 231 to extract a registered password, and compares the password with the received password 232 to confirm that they match. Confirm your identity. As a result, the inquiry service processing means 2 transmits the received seal image 236 to the seal image processing means 7 when the passwords match and it can be confirmed that the customer is the principal.

S13: The seal image processing means 7 adds the output value (G) of the green signal component and the output value (B) of the blue signal component by adding 2 from the output value (R) of the red signal component of the received seal image 236. The seal image 238 of the output value (R − ((G + B) / 2)) obtained by subtracting the output value divided by is generated.
When the seal image 238 is generated, the seal image processing unit 7 transmits the seal image 238 to the verification unit 4. At this time, the verification unit 4 receives the account number 231 from the inquiry service processing unit 2. The account number 231 may be received from the inquiry service processing means 2 via the seal image processing means 7.

S14 to S16: Since they are the same as those of the second embodiment, the description thereof is omitted.
As described above, in the third embodiment, in addition to the effects of the second embodiment, the accuracy of seal verification is improved by removing the background portion from the seal image photographed by the mobile terminal. The effect that it can be made is acquired.

The fourth embodiment is the case where there is a defect in the seal image or seal image taken with the portable terminal as compared with the first embodiment, the second embodiment, and the third embodiment, or the registered seal registered. In the case where there is a mismatch, the function for requesting the customer to transmit a photographed image again and the function for restricting the use of the customer are added.

If it is determined that they match, the collation unit 4 transmits the result to the inquiry service processing unit 2 as a determination result notification 24, and the process proceeds to S26. If it is determined that they do not match, the process proceeds to S252.

  S252: The collation means 4 determined not to match is subject to whether or not the imprint image 234 for collation is blurred, missing, or out of focus using a known technique, and the image quality (image quality) is low. It is determined whether the imprint image 234 has ensured sufficient image quality necessary for collation. As a result, if it is determined that sufficient image quality of the imprint image 234 cannot be ensured, the process proceeds to S253, and if it is determined that sufficient image quality is ensured, the process proceeds to S254.

S253: The collation unit 4 that has determined that sufficient image quality of the imprint image 234 has not been secured transmits a notification to the inquiry service processing unit 2 as a determination result notification 24 to request transmission of a reprinted imprint image. The process proceeds to S26.
S254: The collation unit 4 that has determined that sufficient image quality of the seal imprint image 234 has been secured adds 1 to the number of inquiries, and determines whether or not the number of inquiries has exceeded the limit number of times as a threshold. This inquiry count is stored for each customer identified by the account number 231 in a storage means (not shown) of the verification means 4, and the limit number is stored in advance in the storage means.

As a result of the determination, if the collation unit 4 determines that the limit number has been exceeded, the process proceeds to S255, and if it is determined that the limit number has not been exceeded, the process proceeds to S256.
S255: The collation unit 4 that has determined that the limit number has been exceeded transmits, to the query service processing unit 2 as a determination result notification 24, a notification that the provision of the seal stamp inquiry service has been stopped when the limit number has been exceeded. Then, the process proceeds to S26.

S256: The collation unit 4 that has determined that the limit number has not been exceeded transmits a notification of the remaining number of times of use of the registered seal inquiry service to the inquiry service processing unit 2 as the determination result notification 24, and the process proceeds to S26.
S26: The inquiry service processing means 2 sets a limit number of times that the imprint 22 photographed based on the received judgment result notification 24 matches the registered imprint of the registered seal, requests transmission of a reprinted imprint image, and so on. A notification indicating that the provision of the registered seal inquiry service is to be stopped due to exceeding or a notification indicating the number of times of use of the remaining registered seal query service is transmitted to the mobile terminal 1.

The portable terminal 1 notifies that the imprint 22 taken on the basis of the received notification matches the registered imprint of the registered seal, requests the transmission of a reprinted imprint image, and reports that the limit has been exceeded. Is displayed on the display means 14 to inform the customer of the fact that the service is stopped or the number of times of use of the remaining registered seal inquiry service is displayed.
