DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seal verification apparatus for registering and verifying a seal.

[0002]

2. Description of the Related Art Conventionally, in a financial institution such as a bank or a shinkin bank, a seal is registered in advance in order to perform seal verification as a means of personal identification at the time of transaction such as deposit withdrawal. In many financial institutions, a "seal column" is provided in the passbook as a secondary seal form, so that users can identify the registered seal later, as collation data, and the registered seal is stored there. It is issued by stamping.

[0003]

However, for example, as described in the document: Verification technology of seal signatures and the practice of tellers, supervised by Kinichi Machida, the bankbook was stolen as stated in the Bank Training Company in 1966. In such a case, there is a problem that it may be a target of forgery. To solve this problem, there has recently been a move by financial institutions to abolish the passbook section of the passbook. However, if the seal is not recorded in the passbook in this way, there is no way for the user to know which seal has been registered in the passbook (account), which impairs the convenience of the user. There was a problem.

[0004]

The present invention employs the following structure to solve the above-mentioned problems. <Structure 1> A registered seal image database for storing the registered seal image, a passbook held by the user and recording only a part of the registered seal image, a registered seal image and a registered seal image of the registered seal image database A seal verification device, comprising: a verification unit that verifies an image and outputs a verification result.

<Structure 2> In the seal verification device described in Structure 1, the verification unit uses the seal image recorded in the passbook as a public area, an image of a seal seal image to be verified corresponding to the public area, and a registered seal image. A public area collating unit that performs collation with an image corresponding to the public area, and a remaining area of the public area in the registered seal image of the registered seal image database when the result of the comparison by the public area collation unit is true. A seal verification apparatus, comprising: a secret area collation unit that collates a secret area with an image corresponding to a secret area of a seal imprint to be collated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to specific examples. First, the outline of the present invention will be described.

<< Summary of the Invention >> In the present invention, in order to prevent a seal from being forged by a seal in a seal stamp column in a passbook, only a part of a registered seal image is recorded as a public area in the passbook. It was done. FIG. 5 is an explanatory diagram of the public imprint. As shown in the figure, the registered seal image is an image of all areas, only a part of the area is described as a public seal image in the seal column of the passbook, and the remaining area is a private seal image.
As described above, since the seal imprinted on the passbook is only a part of the area, the remaining area is unknown for forgery. On the other hand, since a plurality of seals owned by a user generally differ greatly in size, shape, character shape, and the like, the user can identify himself only with an image of a partial area recorded in the passbook. it is conceivable that. The present invention pays attention to this point, and is a seal verification device that prevents forgery due to plagiarism and ensures user convenience.

<Example 1><Configuration> FIG. 1 is a configuration diagram showing Example 1 of a seal verification device according to the present invention. The apparatus shown in the figure comprises a scanner 1, an imprint division unit 2, a collation unit 3 (public area collation unit 4, private area collation unit 5), a registered imprint database 6, an imprint mask database 7, a passbook printer 8, and a display unit 9. .

The configuration shown is an example in which the registration function unit and the collation function unit are realized on the same device such as a personal computer. Here, the configuration used for registration / collation is as follows. Registration: Scanner 1, Imprint division unit 2, Registration imprint database 6, Imprint mask database 7, Passbook printer 8 Collation: Scanner 1, Collation unit 3 (public area collation unit 4, private area collation unit 5), Registration imprint database 6 , Imprint mask database 7, display unit 9

As described above, the scanner 1 is an optical reader used for both the registration and collation operations. In the case of the registration operation, the scanner 1 reads the registration form 100 on which the seal is stamped, and in the case of the collation operation. This is a device that reads a form such as an account transfer form on which a user has stamped a seal, and outputs it as image data. The imprint division unit 2 stores the registered imprint in the registered imprint database 6 based on the image data of the registration form 100 read by the scanner 1 during the registration operation,
The registered seal is divided into a public area and a non-public area.
It has a function of storing the divided area data as mask information in the imprint mask database 7.

The collation unit 3 has a function of collating the collation imprint image read by the scanner 1 with the registered imprint image stored in the registered imprint database 6.
The public area collating unit 4 obtains an image corresponding to the public area in the imprint to be verified based on the mask information in the imprint mask database 7, and discloses the image of the public area and the registered imprint image in the registered imprint database 6. It has a function of collating with an image corresponding to an area. In addition, when the comparison result of the public area collation section 4 is true (accept), the private area collation section 5 determines an image corresponding to the private area in the collation imprint based on the mask information in the seal imprint mask database 7. And has a function of comparing the image of the private area with the image corresponding to the private area of the registered seal image in the registered seal database 6. The imprint division unit 2 and the collation unit 3 are realized by software having a function corresponding to the imprint division processing and the collation processing, and hardware such as a processor and a memory for executing the software.

The registered imprint database 6 is a database for storing the image data of the registered imprint read by the scanner 1. The imprint mask database 7 is a database that stores, as mask information, information on the area divided into two by the imprint dividing unit 2, that is, how the registered imprint is divided. The passbook printer 8 is a printer that prints only the public area of the seal imprint divided by the seal imprint dividing unit 2 when issuing the passbook 200 at the time of imprint registration.
The display unit 9 is a display for displaying a comparison result of accept or reject (false) at the time of collation.

<Operation> FIG. 2 is a flowchart showing the operation of the first embodiment. First, the operation at the time of registration will be described.

<Step S1> An operator (an employee of a financial institution, for example) reads the registration form 100 on which the registered seal is stamped by the scanner 1, and the scanner 1 converts the form into a digital image. <Step S2> The operator selects a registration process. <Step S3> The seal imprint dividing unit 2 extracts the seal imprint area in the image of the registration form 100, and divides the registered seal imprint into two parts by providing an arbitrary straight line passing through the center of the seal imprint area. , And the other is a secret area (see FIG. 5). <Step S4> The seal imprint division unit 2 simultaneously extracts a registered seal imprint image and stores it in the registered seal imprint database 6.

<Step S5> The seal imprint division unit 2 stores, as mask information, in the seal imprint mask database 7 a parameter indicating the dividing straight line in step S3 and a flag indicating which of the two areas divided by the straight line is an open area. <Step S6> The seal imprint dividing section 2 sends the seal imprint image of only the area defined as the public area to the passbook printer 8, which is divided by the above-described dividing line, and the passbook printer 8 prints this in the seal column of the passbook. As a result, only the imprint image of the public area is recorded in the passbook 200.

Next, the operation at the time of collation will be described. <Step S1> An operator (an employee of a financial institution, for example) reads a stamp form (not shown) such as a fund transfer form with the scanner 1, and the scanner 1 converts this into a digital image. <Step S2> The operator selects the collation processing. <Step S7> The open area collation unit 4 determines the division straight line parameters and the flag from the imprint mask database 7,
The registered seal imprint images are read from the registered seal imprint database 6 and are compared with the registered seal imprint images only in the public areas of the seal imprints in the form. Although three types of imprints may be input to the input form: a correct imprint, a different imprint, and a forged imprint, many of the different imprints are rejected in this step. <Step S8> If the processing result of step S7 is rejected, the process proceeds to end processing after step S10,
If it is accepted, the process proceeds to a secret area collation process in step S9.

<Step S9> If the public area collating unit 4 determines that the acceptance is accepted, the private area collating unit 5 receives the form image, the registered seal image and the private area information from the public area collating unit 4, and receives the form image. The matching process is performed only in the non-disclosed area, and the result is output. <Step S10> The display unit 9 displays the comparison results of the public area collation unit 4 and the private area collation unit 5 and shows them to the operator. That is, the public area collating section 4 and the private area collating section 5
If the collation result is "accept", it is a correct seal. If the collation result of the public area collation unit 4 is reject, a different seal. The collation result of the public area collation unit 4 is "accept" but private area collation. If the collation result of the unit 5 is reject, it is determined that there is a suspicion of a forged seal.

<Effects> As described above, according to the first embodiment,
The verification process is performed using the registered seal and the seal to be verified, and only a part of the registered seal is described in the passbook. For the person, there is an effect that it is possible to identify which seal is used. Further, the collation unit 3 is divided into a public area collation unit 4 and a private area collation unit 5, and the comparison by the private area collation unit 5 is performed only with respect to the imprint to be collated by the public area collation unit 4. Therefore, different imprints can be rejected at high speed, and as a result, processing can be speeded up. Then, for example, by adopting a configuration in which the comparison is performed roughly on the public area and the comparison is performed finely on the non-public area, countermeasures against counterfeit seals by analogy of the non-public area are further ensured, and In addition, the processing speed can be further increased.

<< Specific Example 2 >> The specific example 1 has an effective configuration for an apparatus in which the imprint image of the registration form is registered in a unified manner and a partial copy of the imprint image is printed on the passbook 200 by the passbook printer 8. The specific example 2 is an apparatus which is effective for a configuration in which a registration stamp is directly imprinted on the passbook 200 instead of using the passbook printer 8. That is, at the time of registration of a seal stamp, the operator not only stamps the registered seal stamp on the registered seal stamp form, but also stamps the same registered seal stamp on the seal column of the passbook. At this time, only a part of the seal is imprinted on the passbook to make it a public area by means such as inserting paper between the passbook and the seal.

<Structure> FIG. 3 is a diagram showing the structure of the second embodiment. The apparatus shown in the figure includes a scanner 11, an imprint registration unit 12, a collation unit 13 (a public area collation unit 14, a private area collation unit 1).
5) A public seal imprint database 16, a registered seal imprint database 17, and a display unit 18.

In the second embodiment, as in the first embodiment, the registration function unit and the collation function unit are realized on the same device such as a personal computer. Here, the configuration used for registration / collation is as follows. Registration: scanner 11, imprint registration unit 12, public imprint database 16, registered imprint database 17 Collation: scanner 11, collation unit 13 (public area collation unit 1)
4. Closed area collation unit 15), public imprint database 1
6. Registration imprint database 17, display unit 18

The scanner 11 is an optical reading device used for both registration / collation operations, similarly to the scanner 1 of the first embodiment. In the case of the registration operation, the registration form 10 stamped with a seal is used.
While reading 0, the image of the passbook 200 in which a part of the area of the seal is imprinted is read. The seal imprint registration unit 12 extracts a public seal imprint of a seal stamp column from the image of the passbook read by the scanner 11, records this in the public seal imprint database 16, and extracts a registered seal imprint from the image of the registration form. 17 is provided.

The collating unit 13, like the collating unit 3 of the first embodiment, performs a function of collating the image of the imprint to be verified read by the scanner 11 with the image of the registered imprint stored in the registered imprint database 17. have. Of which
The public area collating unit 14 obtains an image corresponding to the public area of the imprint to be verified based on the image of the public area recorded in the public imprint database 16, and records the image corresponding to the public area and the registered imprint database 17. It has a function of comparing the registered imprint with the image corresponding to the disclosed area. In addition, when the result of the comparison by the public area collating unit 14 is true, the private area collation unit 15 obtains an image corresponding to the private area of the seal to be collated based on the mask information in the seal mask database 7. , An image of this private area,
It has a function of collating the registered seal imprint image in the registered seal imprint database 17 with an image corresponding to a secret area. still,
The imprint registration unit 12 and the collation unit 13 are realized by software corresponding to each function and hardware such as a processor and a memory for executing the software.

The public seal imprint database 16 stores the passbook 200
Is a database for recording imprint image data of a public area recorded in the public area. The registered seal imprint database 17
This is a database for recording the image data of the registered seal imprint recorded on the registration form 100. The display unit 18 is a display for displaying a comparison result of accept (true) or reject (false) at the time of collation.

<Operation> FIG. 4 is a flowchart showing the operation of the second embodiment. First, the operation at the time of registration will be described.

First, as a pre-processing of the registration operation, the operator (an employee of a financial institution, for example) stamps the user's registered seal on the registration form 100 and also stamps the same registered seal on the seal field of the passbook 200. . At this time, in the passbook 200, paper or the like is interposed between the seal and the seal column of the passbook 200, and the passbook 2
The seal imprint on 00 is partially masked, and the seal imprint in the seal column is limited to a partial area as shown in the public seal imprint of FIG.

<Step S101> The operator inputs the registration form 100 and the passbook 200 with the scanner 11, and the scanner 11 converts the digital form into a digital image. <Step S102> The operator selects a registration process. <Step S103> When the image of the passbook 200 is input by the scanner 11, the process proceeds to the public seal recording process of step S104, and when the image of the registration form 100 is input, the process proceeds to the registered seal recording process of step S105. <Step S <b>104> The seal imprint registration unit 12 extracts the public seal image in the seal column of the passbook 200 and records this in the public seal database 16. <Step S105> The imprint registration unit 12 checks the registration form 10
A registered seal image of 0 is extracted and recorded in the registered seal database 17.

Next, the operation at the time of collation will be described. <Step S101> The operator (e.g., an employee of a financial institution)
A seal form (not shown) such as an account transfer form is scanned by the scanner 11.
And the scanner 11 converts this into a digital image. <Step S102> The operator selects the collation processing. <Step S106> The public area collating unit 14 extracts the public seal image from the public seal image database 16, finds an area in the collated seal imprint that is equal to the area of the public seal image, and obtains the seal image of this area and the registered seal image database. 17
Is compared with the image corresponding to the public area of the registered seal imprint image read from. Although three types of imprints may be input to the input form: a correct imprint, a different imprint, and a forged imprint, many of the different imprints are rejected in this step. <Step S107> If the processing result of step S7 is rejected, the process proceeds to end processing after step S109, and if it is accepted, the process proceeds to the secret area collation processing of step S108.

<Step S108> Open area collation unit 14
Is determined to be accept, the secret area collating unit 15
Receives the form image, the registered seal image, and the non-public area information from the public area collating unit 14, performs the collation processing only on the non-public area of the form image, and outputs the result. <Step S109> The display unit 18 displays the public area collation unit 1.
4 and the collation result of the secret area collation unit 15 are displayed and shown to the operator. That is, if the comparison result of the public area collation unit 14 and the non-public area collation unit 15 is “accept”, the seal is correct, and if the collation result of the public area collation unit 14 is reject, a different seal and public area collation is used. Part 14
Is the accept, but the secret area collating unit 15
If the collation result is reject, it is determined that there is a suspicion of a forged seal.

<Effects> As described above, according to the specific example 2,
The verification process is performed using the registered seal and the seal to be verified, and only a part of the registered seal is described in the passbook. For the person, there is an effect that it is possible to identify which seal is used. Further, the collating unit 13 is divided into a public area collating unit 14 and a private area collating unit 15, and the private area collating unit 15 performs collation only on the imprint to be collated by the public area collating unit 14. , Different imprints can be rejected quickly, and as a result,
Processing can be speeded up. Then, for example, by adopting a configuration in which the comparison is performed roughly on the public area and the comparison is performed finely on the non-public area, countermeasures against counterfeit seals by analogy of the non-public area are further ensured, and In addition, the processing speed can be further increased. Further, the specific example 2 has an effect that the present invention can be applied to a configuration in which a seal is directly stamped on the passbook 200 without using a passbook printer.

<< Usage Mode >> In each of the above specific examples, the division of the public seal and the private seal is performed using a straight line passing through the center of the seal.
Although an example of division has been described, the present invention is not limited to this division method, and any method such as division by a curve may be used as long as an area is divided.
