In the seal verification process, there is a pre-process performed at a branch office or the like before a foreign agent goes to a customer, and a verification process performed at a customer.

In the pre-processing, first, the ID of the external member and the fingerprint information used for authentication are set in the server 6 (step 101). The registration of fingerprint information in the public relations member fingerprint database 60 uses the seal stamp verification terminal 1 to capture a fingerprint image of a finger used for fingerprint verification when the public relations member uses the registered seal at the customer. Note that a fingerprint image may be captured using a different device. Then, a feature is extracted from the captured image to create a fingerprint matching parameter, and the created fingerprint matching parameter is registered in the outsider fingerprint database 60 using the outsider ID as a key.

When this setting is completed, a predetermined registered imprint is encrypted and recorded on the memory card 5 (step 102). The details of the processing in step 102 will be described later. Subsequently, a decryption key for decrypting the encrypted registration imprint recorded on the memory card 5 is registered in the decryption key database (step 103), and the pre-processing is terminated. This preprocessing may be performed by a public relations member or by another person in charge.

When the pre-processing is completed, the public relations officer goes to the customer carrying the seal verification terminal 1 and the like (the seal verification terminal 1 into which the memory card 5 is inserted), and conducts public relations work including the seal verification processing. I do. In the seal verification process, the registered seal is obtained from the memory card 5 (step 151), the seal to be verified is obtained from the request form or the like using the image input device 2 (step 152), and the verification support display of the seal verification terminal 1 is performed. , The registered seal imprint is compared with the seal imprint to be verified (step 153). As a result, if it is determined that the seals match (YES in step 154), the verification processing is terminated as seal seal OK, and the seals match. If you decide not to (Step 1
(NO in 54), the seal verification process is determined to be NG, and the verification process ends.

Next, details of the processing in step 102 and steps 151 to 153 will be described. FIG. 5 is a flowchart showing details of the recording process of the registered seal imprint in step 102.

To record the registered seal imprint on the memory card 5, first, a public relations member prepares a schedule list of the visit destination (step 2).
01), a list of account numbers of visiting customers is created from the created list (step 202).

Next, the server 6 obtains an account number from the list of account numbers (step 203), and the imprint search unit 67 searches the imprint database 62 for a registered imprint corresponding to the account number (step 204). Subsequently, the seal imprint encryption unit 6
8 randomly generates an encryption key (step 205), and performs an encryption process on the registered seal imprint searched by the seal imprint search unit 67 using the generated encryption key (step 206).

When the registration imprint is encrypted, the memory card writing unit 69 records the encrypted registration imprint on the memory card 5 (step 207), and the key registration unit 66
Registers the corresponding decryption key in the decryption key database 61 using the public relations member ID and the account number as keys.

These processes are performed on all the accounts included in the previously created visitor list (NO in step 209). When the processes on all the visits are completed (YES in step 209), the registration imprint is performed. The recording process ends.

FIG. 6 is a flowchart showing the details of the registered seal imprint acquiring process in step 151.

In the process of acquiring a registered seal imprint, first, the liaison member enters the liaison ID from the key input section 19 of the seal verification terminal 1 at the customer.
Is input (step 211), and an account number is input (step 212). Next, the fingerprint image input adapter 3 is attached to the image input device 2 to capture the fingerprint image of the external member (step 213). The fingerprint image captured by the seal verification terminal 1 is corrected by the image distortion correction unit 11 and then input to the fingerprint verification parameter generation unit 12, and the fingerprint verification parameter generation unit 12 calculates a feature amount and generates a fingerprint verification parameter. Is performed (step 214).

Next, an external member ID, a fingerprint collation parameter, and an account number are transmitted to the server 6 using the portable communication device 4 (step 215).

When server 6 receives the member ID, fingerprint matching parameter, and account number (step 216), fingerprint matching section 64 searches fingerprint member 60 from the member fingerprint database 60 for a fingerprint matching parameter corresponding to the member ID. (Step 217). Then, the received fingerprint collation parameters are collated with the fingerprint collation parameters obtained from the public relations fingerprint database 60 to authenticate the external party (step 218). If the authentication is successful, the key search unit 65 extracts the decryption key stored in association with the external member ID and account number received from the decryption key database 60 (step 219), and sends it back to the seal verification terminal 1 (step 219). 220).

Upon receiving the decryption key (step 221), the seal verification terminal 1 transmits the encrypted registered seal corresponding to the account number input from the key input unit 19 to the memory card reading unit 14 from the memory card 5. (Step 222), the registered imprint is decrypted using the received decryption key (Step 223), and the registration imprint acquisition process ends.

FIG. 7 is a flow chart showing the details of the process of acquiring the imprint to be verified in step 152.

In the process of obtaining the imprint to be verified, a public relations person first places the image input device 2 on a request form or the like on which the imprint to be verified is stamped (step 231), and pushes a push button (not shown) of the image input device 2. Press (step 232). In the image input device 2, a CCD camera (not shown) operates in response to pressing of the push button as a trigger, and an image is input to the seal verification terminal 1 (step 233). Due to the portability of the image input device 2, the distance between the CCD camera and the subject is shortened, and barrel distortion occurs in the input image. Therefore, the image distortion correction unit 11 corrects the barrel distortion (step 234), and ends the process of acquiring the seal imprint to be verified.

FIG. 8 is a flowchart showing details of the collation support display processing in step 153.

In the collation support display process, first, the seal stamp collation operation unit 16 corrects a shift of the collation imprint image with respect to the registered imprint image (step 241). The shifts to be corrected here are horizontal and vertical shifts and rotational angle shifts. Subsequently, the seal stamp collation operation unit 16 superimposes the registered seal imprint image and the collated seal imprint image (step 24).
2). Thereafter, the degree of overlap between the two imprints is quantified (step 243), and a display message for assisting the determination of the outsider is created based on the numerical value of the degree of overlap (step 244).

The results of steps 242 to 244 are respectively displayed on the display unit 18 by the display control unit 17, and the display content is such that the overlap of the two imprints is a common background portion and the two imprints are the same. Imprint display (step 24), which is divided into four types: an overlapped portion, a registered mark only portion, and a verified mark only portion, and displayed in different colors.
5), display of a numerical value of the degree of overlap (step 246),
Display of a message that assists in determining a member based on the numerical value of the degree of overlap (step 247). For example, if the numerical value of the degree of overlap is smaller than a certain set value, a message such as “Caution required!” Is displayed.

Next, the flow of the foreign affairs business using the seal verification terminal 1 will be described. FIG. 9 is a flowchart showing the flow of the public relations business using the seal verification terminal 1.

First, the external member registers fingerprint information in advance in the external member fingerprint database 60 (step 30).
1). The public relations member prepares a visit destination list before going out for public relations work (step 302). Create a list of account numbers required from the visited list (step 303),
The registration imprint of each account is extracted, encrypted and stored in the memory card, and at the same time the decryption key is registered in the database (step 303).

Next, the public relations officer visits the customer with the memory card 5 storing the encrypted seal and the seal verification terminal 1 (step 304). The liaison member who received the request form at the visiting location inputs his / her fingerprint image to the seal verification terminal 1, and stores the liaison member ID, the fingerprint collation parameters created by extracting features from the fingerprint image, and the account number into the server of the sales office. 6 (step 305). The server 6 authenticates the external party by fingerprint collation (step 306). If the authentication succeeds, the server 6 searches for a corresponding decryption key and retrieves the seal stamp collation terminal 1.
(Step 307).

Upon receiving the decryption key for decrypting the imprint of the account stored in the memory card 5, the seal verification terminal 1 decrypts the registered imprint read from the memory card 5 using the received decryption key. It is used as a registered seal (step 308).

When the seal imprinted on the request form is taken in from the image input device 2, the seal stamp collation terminal 1 performs collation support such as superimposition of the seal imprints and calculation of the collation rate based on the two seal imprints ( (Step 309), and the result is displayed (Step 310).

A public relations member performs collation determination based on the collation support display, and if the seal is incorrect (N in step 311)
O), the seal is corrected on the spot and the verification is performed again. If the seals match (YES in step 311),
The public relations member brings back the request form (step 312) and starts business processing at the branch office (step 313).

By the way, in the above-described embodiment, the customer obtains the registered seal after stamping the request form. However, the customer may use a different seal for each account, and the customer may need to use a different seal. You may not know the sign. Therefore, when recording the registered seal imprint on the memory card 5, the registered seal imprint of all the transaction accounts of the visiting customer is recorded, and the registered seal imprint required for the transaction is displayed on the seal verification terminal 1 based on the account number. You can check the mark.

In the above-described embodiment, only the registered seal is stored in the memory card. However, by recording the registered signature, the information such as the account holder can be confirmed at the customer.

In the above embodiment, the memory card 5
In the above description, the encrypted registration seal is recorded, the fingerprint information is sent to the sales office, the decryption key is received, and then the decryption key is received. Can be performed without performing the communication of the seal stamp. However, even in this case, the use of the seal verification terminal 1 is limited to only those members who have been authenticated by fingerprint verification or the like.

In contrast to the above embodiment, the decryption key for each account number is stored in
The encrypted stamp image is stored in the server 6 and the account number and the public relations officer I are sent to the server 6 from the seal verification terminal at the time of verification.
D. The fingerprint information may be sent, and the server may authenticate the liaison member based on the liaison ID and the fingerprint information, and then transmit the registered seal imprinted with the encryption process corresponding to the account number.

Further, the decryption key for each account number is stored in the memory card 5 and the encryption key for each account number is stored in the server 6. After sending the fingerprint information, the branch office authenticates the liaison member with the liaison ID and fingerprint information, searches for the registration imprint and encryption key corresponding to the account number, encrypts the registration imprint,
It may be configured to transmit to the seal verification terminal 1.

Further, it is also possible to adopt a configuration in which both the registered seal imprint and the decryption key are recorded in the memory card 5. In this case, the correspondence between the registered imprint and the decryption key is not easily understood. For example, an ID is randomly assigned to each of the registered seal and the decryption key, and these are stored in the memory card 5 as shown in FIG. Then, the correspondence between the registered seal and the decryption key is stored in the database of the sales office. In this case, at the time of verification, when the seal number verification terminal 1 sends the account number and the outsider ID fingerprint information to the business office, the business office authenticates the public relations person and decrypts the ID number of the registered seal required for verification from the account number. The key ID is searched and sent to the seal verification terminal 1. The seal verification terminal 1 reads the encrypted registered seal and decryption key from the memory card 5 using the received ID, and uses it for verification.
