Abstract

PURPOSE:To eliminate a standby time for data transfer by providing a display device and a storage part, which stores more than two data to be collated, in a data display part, retrieving data to be collated, which are stored in a data file, and transferring the data to be collated to the data display part for each unit when an idle area is generated in the storage part. CONSTITUTION:When the idle area unnecessary for the display of a display device 3 is generated in a storage part 35, it is an information control means 47 informs a data retrieval part 2 that the idle area is generated. In the data retrieval part 2, the information are recognized by a transfer control means 27. The transfer control means 27 drives a retrieval control means 26 and reads the data to be collated, which are required for a data display part 3, from a data file 24. The transfer control means 27 transfers these read print data to the data display part 3. In the data display part 3, these transferred print data are stored to the idle area of the storage part 35. Thus, since the plural data to be collated are stored in the storage part 35, it is not necessary to wait for the transfer of the data to be collated from the data retrieval part each time collation processing is executed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a data verification device for verifying the authenticity of data.

(Prior art) For example, when cashing a check at a financial institution, etc.
It is necessary to determine whether this check is legitimate or not.

Generally, when determining the validity of a check, the impression of a seal affixed to the check is compared with a previously registered seal impression. As a result of this verification, if it is determined that there is a match, the check is cashed.

A data verification device is used to verify such seal impressions.

FIG. 2 shows a block diagram of a conventional data matching device.

In the figure, a data matching device 1 includes a data search section 2 and a data display section 3.

The data search section 2 and the data display section 3 are connected by an interface cable 4.

The data search unit 2 includes a search order storage unit 22, an input/output control unit 23, and a data file 24, which are connected to the processor 21.

The search order storage section 22 is composed of a RAM and the like that temporarily stores the account numbers of checks sent from the data display section 3 in the order in which they are sent. The input/output control section 23 is a circuit that matches the signal format within the data search section 2 (for example, a serial signal) and the signal format on the interface cable 4 (for example, a parallel signal). The data file 24 is constituted by a hard disk device or the like that stores multiple units of data to be verified, that is, stamp impressions of checks converted into image information. Note that here, one unit of seal impression refers to image data for one seal. The processor 21 includes a sequence control means 25.
and search control means 26 are provided. Sequence control means 2
5 controls access to the search order storage unit 22. The search control means 26 controls reading out predetermined seal impression data from the data file 24 in response to instructions from the data display section 3.

Next, the data display section 3 includes a keyboard 32, a display 33, and an input/output control section 34 connected to the processor 31.
, a storage section 35, and a magnetic ink reader 36.

The purpose of this is to carry out The processor 31 is provided with a display control means 45 and a command control means 46.

The display control means 45 controls displaying the seal impression on the display 33 based on the contents of the storage section 35. The command control means 46 recognizes various types of information input through the keyboard 32 and controls the transfer of data to the data search section 2.

When attempting to perform seal verification using the apparatus configured as described above, the operator must input information identifying the check to be verified, such as an account number (initial setting). A magnetic ink reader 36 is used to input this account number. Generally, account numbers printed on checks are printed using magnetic ink. This ink is read using a magnetic ink reader 36, and the read information is stored in the search order storage section 22 of the data search section 2. Actually, the magnetic ink reader 36
Each time the account number is read, the command control means 46 drives the input/output control section 34 to transfer the account number to the data search section 2. In the data search section 2, the input/output control section 23
When it receives this account number, it notifies the order control means 25 of the processor 21. The order control means 25 stores the notified account number in the search order storage section 22.

The above process is repeated until the magnetic ink reader 36 finishes reading. For example, if there are 100 checks for which seal verification is to be performed, the 100 checks will be read continuously by the magnetic ink reader 36. The read information such as the account number is stored in the search order storage unit 22 of the data search unit 2 as the first account number to the 100th account number according to the reading order.

The operation of the data verification device when the operator actually performs seal verification after the above initial settings are completed will be described with reference to FIG.

FIG. 3 is a sequence chart of a conventional data matching device.

The processing on the left side of the figure shows the operation of the data search unit 2, and the process on the right side of the figure shows the operation of the data display unit 3.

The operator first uses the keyboard 32 to input the account number of the check whose seal is to be verified. Here, it is assumed that the operator checks the seal of the 50th check out of 100 checks that were previously read using the magnetic ink reader 36. Therefore, the operator uses the keyboard 32 to input the fiftieth account number.

The command control means 46 of the processor 31 drives the input/output control section 34 to transfer the input 50th account number to the data search section 2 as a start of seal verification (step S1). When the input/output control section 2 receives this fiftieth account number, it notifies the search control means 26 of the processor 21. The search control means 26 stores one unit of seal impression data corresponding to this account number in the data file 2.
Read from 4. The read seal imprint data is transferred to the data display section 3 via the input/output control section 23 (step S
2) When the input/output control section 34 receives the seal impression data, it notifies the display control means 45 of the processor 31. The 0 display control means 45 temporarily stores the transferred seal impression data in the storage section 35. Further, the seal impression data stored in the storage section 35 is displayed on the display 33. The operator visually compares the seal imprint data displayed on the display 33 with the seal imprint pressed on the check in hand. When this verification is completed, the operator presses the completion key 41 on the keyboard 32. When the command control means 46 recognizes that the completion key 41 has been pressed, it drives the input/output control section 34 to transfer a verification completion notification to the data search section 2 (step S3). The input/output control section 23, which has received this verification completion notification, notifies the search control means 26 to that effect. The search control means 26 drives the order control means 25 to search the fifth
The account number next to the account number 0 is read from the search order storage unit 22. As a result, the search control means 26 recognizes the next account number after the 50th account number, that is, the 51st account number, and reads out the seal impression data of this 51st account number from the data file 24. Furthermore, the input/output control unit 23 is driven to transfer the seal imprint data of this 51st account number to the data display unit 3 (step S4).In the data display unit 3, the seal imprint verification is performed in the manner described above. be exposed.

As explained above, conventionally, seal imprint data was transferred one unit at a time from the data retrieval device 2 to the data display unit 3 each time seal verification was completed. For this reason, the data display section 3 has had to wait until new seal imprint data is sent after seal verification is completed. Therefore,
It is extremely difficult to quickly complete a large number of verification processes.

The present invention has been made with attention to the above points, and an object of the present invention is to provide a data matching device that can immediately perform seal matching without waiting for data transfer after seal matching is completed. It is.

(Means for Solving the Problems) A data collation device of the present invention includes a data search unit including a data file storing a plurality of units of data to be collated, and a data search unit that receives the data from the data search unit and displays the data. In the data matching device, the data display section includes a display device that displays the data to be matched, a storage part that stores two or more pieces of the data to be matched, and a free space in the storage part. a notification control means for notifying the data search unit that the data has occurred, and the data search unit receives one unit of any of the collated data stored in the data file in a preset order. The apparatus includes a search control means for searching, and a transfer control means for transferring the collated data one unit at a time to the data display section in response to a notification from the notification control means.

(Operation) The above device stores two or more pieces of data to be matched in the storage unit of the data display unit, and displays the data to be matched on the display device. When a free space that is not necessary for display on the display device occurs in the storage section, the notification control means notifies the data search section that the free space has been created. In the data search unit, upon receiving notification that a free space has been generated, the transfer control means recognizes the notification. The transfer control means drives the search control means to read out collated data required by the data display section from the data file. The transfer control means transfers the read seal impression data to the data display section. The data display section stores the transferred seal imprint data in an empty area of the storage section. In this way, since a plurality of pieces of data to be matched are stored in the storage unit, there is no need to wait for the data to be matched from the data search unit to be transferred each time a matching process is performed.

Here, response notification will be explained using FIG. 4.

FIG. 4 is a conceptual diagram of response notification according to the present invention.

As shown in FIG. 4, the response notification is provided with a notification type 50 indicating that it is a response notification in the data search section 2, and a device address 51 that specifies the data display section 3. Furthermore, the following items are provided: header 52, command code 53, chain information 54, detailed status 55, device status 56, data length 57, and data 58.

The header 52 indicates the communication format between the data search section 2 and the data display section 3. Command code 53 indicates the purpose of communication. Chain information 54
indicates that the data to be matched is image data. The detailed status 55 indicates the content of the error when an error occurs in the data display section 3. The device status 56 indicates the status of each part of the data display section 3, and includes an item 56a indicating the number of free areas in the storage section 35. Data length 57 indicates the length of data 58, which is the next item. The data 58 is comprised of data transferred from the data display section 3 to the data search section 2, such as the contents of a register indicating the status of an error occurring within the data display section 3. Note that the verification completion notification also has the same item configuration as this response notification, and the content of the notification type 50 is set to indicate a verification completion notification.

Now, returning to FIG. 1 again, the data display unit 3 includes a keyboard 32 connected to a processor 31, a display 3

The magnetic ink reader 36 is a device that reads magnetic ink.
gneticInk Character Recog
The purpose of this is to carry out The processor 31 is provided with a display control means 45, a command control means 46, and a notification control means 47.

The display control means 45 controls displaying the seal impression on the display 33 based on the contents of the storage section 35. The command control means 46 recognizes various types of information input through the keyboard 32 and controls data transfer to the data search section 2. The notification control unit 47 notifies the data search unit 2 of the presence or absence of free space in the storage unit 35. It is assumed that the storage unit 35 is provided with an area for storing three units of seal impression data.

When attempting to perform seal verification using the apparatus configured as described above, the operator must input information identifying the check to be verified, such as an account number (initial setting). A magnetic ink reader 36 is used to input this account number. Generally, account numbers printed on checks are printed using magnetic ink. This ink is read using a magnetic ink reader 36,
This read information is stored in the search order storage section 22 of the data search section 2. In reality, each time the magnetic ink reader 36 reads an account number, the command control means 46 drives the input/output control section 34 to retrieve the account number from the data search section 2.
Transfer to. In the data search unit 2, when the input/output control unit 23 receives this account number, it notifies the order control unit 25 of the processor 21. The order control means 25 stores the notified account number in the search order storage section 22.

The above process is repeated until the magnetic ink reader 26 finishes reading. If there are 1 (10) checks for which seal verification is to be performed, these 100 checks will be read successively by the magnetic ink reader 36. Information such as the read account number will be stored in the reading order. Accordingly, the account numbers are stored in the search order storage unit 22 of the data search unit 2 as the 1st to 100th account numbers.

The operation of the data verification device when the operator actually performs seal verification after the above initial settings are completed will be described with reference to FIG.

FIG. 5 is a sequence chart of the data matching device of the present invention.

In the figure, the processing on the left side shows the operation of the data search unit 2, and the process on the right side of the figure shows the operation of the data display unit 3.

The operator first uses the keyboard 32 to input the account number of the check whose seal is to be verified. Here, it is assumed that the operator checks the seal of the 50th check out of 100 checks that were previously read using the magnetic ink reader 36. Therefore, the operator uses the keyboard 32 to input the fiftieth account number.

The command control means 46 of the processor 31 drives the input/output control section 34 to transfer the input 50th account number to the data search section 2 as a start of seal verification (step 5ll). In the data search section 2, when the input/output control section 2 receives the fiftieth account number, it notifies the search control means 26 of the processor 21. The search control means 26 reads out one unit of seal impression data corresponding to this account number from the data file 24. The read seal impression data is transferred to the data display section 3 via the human output control section 23 (step 512). The input/output control section 34 notifies the display control means 45 of the processor 31 when receiving the seal impression data. The display control means 45 stores the transferred seal impression data in the storage section 3.
5 to be temporarily stored. Further, the seal impression data stored in the storage section 35 is displayed on the display 33.

On the other hand, the notification control means 47 determines whether or not there is free space in the storage section 35 and outputs a response notification to the data search section 2. In this case, since only one unit of seal impression data is stored in the storage unit 35, the input/output control unit 35 sends a response notification (the number of free areas “2”) indicating that there is free space.
Notify the data search unit 2 via (step 513)
.

When the input/output control section 23 receives this response notification, it notifies the transfer control means 27. When the transfer control means 27 recognizes from the response notification that there is free space in the storage section 25, it issues an instruction to the search control means 26 to transfer the seal imprint data. Search control means 2
6 drives the order control means 25 to read out the next account number after the 50th account number, that is, the 51st account number from the search order storage section 22. The search control means 26 reads out seal impression data corresponding to the 51st account number read out from the search order storage unit 22 from the data file 24 . The read seal impression data is transferred to the data display section 3 via the input/output control section 23 (step 514). When the input/output control unit 34 receives the seal imprint data, the input/output control unit 34 controls the display control unit 45.
to notify.

The display control means 45 causes the storage unit 35 to temporarily store the transferred seal impression data. This memory is stored in a different area from the storage area of the previously stored seal impression data of the 50th account number. Here, the notification control means 47 transfers the response notification (the number of free areas is "1") to the data search unit 2 (step 515), similarly to step S13 described above. As a result, the seal impression data of the 52nd account number is transferred from the data search unit 2 to the data display unit 3 (step 516). The data display section 3 stores the seal impression data of this 52nd account number in the free space of the storage section 35. When this storage is completed, the notification control means 47
determines that there is no free space in the storage unit 35, and transfers a response notification (number of free spaces “0”) indicating that there is no free space to the data search unit 2. The transfer control means 27 of the data search section 2 recognizes that there is no area to store seal impression data in the storage section 35 of the data display section 3, and interrupts the transfer of new seal impression data.

Now, in the data display section 3, the seal impression data corresponding to the fiftieth account number is first displayed on the display 33. The operator visually compares the seal imprint data displayed on the display 33 with the seal imprint pressed on the check in hand. When the verification is completed, the completion key 41 of the keyboard 32 is pressed. When the command control means 46 recognizes that the completion key 41 has been pressed, the command control means 46 notifies the display control means 45 to that effect. The display control means 45 is
Upon receiving this notification, the seal imprint data corresponding to the 51st account number stored in the storage unit 35 is displayed on the display 33. After performing the verification, the operator will further press the completion key 41. Similar processing is performed on the seal imprint data corresponding to the 52nd account number, and the completion key 41 is pressed. When the command control means 46 recognizes that the completion key 41 has been pressed three times, it notifies the notification control means 47 of this fact. The notification control unit 47 outputs an inquiry completion notification to the data search unit 2 indicating that a free space has been created in the storage unit 35 (step 818).

The input/output control section 23 of the data search section 2 notifies the transfer control means 27 that this notification has been received. Transfer notification means 25
issues an instruction to the search control means 26 to search for seal imprint data.

The search control means 26 drives the order control means 25, and the search control means 26 drives the order control means 25.
The next account number after the second account number, that is, the 53rd account number, is read from the search order storage unit 22. The search control means 26
When the 53rd account number is recognized, the seal imprint data corresponding to that account number is read from the data file 24. Furthermore, this seal impression data is transferred to the display section 3 via the input/output control section 23 (step 519). Thereafter, the seal impression data is stored in the storage unit 35 in the manner described from step S13 onwards. Note that if the collation of the seal imprint data corresponding to the 50th account number transferred in step S12 is completed before outputting the response notification in step S16 (the completion key 41 is pressed), step S1
The response notification No. 5 indicates that there is space in the storage unit 35. Therefore, the seal imprint data corresponding to the 53rd account number will be transferred without waiting for the verification completion notification in step S18.

As explained above, as long as there is free space in the storage section 35, the seal impression data is not transferred from the data search section 2 to the data display section 3 every time the operator finishes the collation work. Therefore, after completing one verification task, the operator can immediately perform another verification task.

The data matching device of the present invention is not limited to the above embodiments.

The configuration of the apparatus may be such that a large number of data display sections 3 are connected to one data search section 2, or the data search section 2 and data display section 3 may be connected via a communication line. Furthermore, although the magnetic ink reader 36 has been described as being used to read checks, the keyboard 32 may also be used to input account numbers and the like. Further, in the embodiment, the verification of seal impressions on checks has been described, but the present invention can also be applied to, for example, verification of fingerprints, as long as a large number of verifications are performed continuously.

(Effects of the Invention) The data matching device of the present invention configured as described above does not require transferring the data necessary for the next matching each time one matching is completed, so there is no waiting time required for data transfer. Therefore, data matching processing can be performed continuously and quickly, and the processing efficiency can be improved.
