Description

[Detailed Description of the Invention] (a) Technical Field of the Invention The present invention relates to a verification device for seal stamps, etc., and particularly to a reseal processing method that can retain and verify the old seal when a seal is resealed.

(b) Background of the technology In recent years, facsimile devices that read documents, drawings, etc. and transmit image data have rapidly become popular as part of efforts to streamline office work. On the other hand, in financial institutions and the like, a method is being attempted in which a customer's seal and a registered seal stamp used on bills, checks, etc. are treated as image data, and the verification is automatically performed using a seal matching device.

The verification device irradiates the stamp to be verified with light and projects it onto an image sensor through an optical lens to obtain image data corresponding to the stamp, which is then compared with the image data of the registered seal.This verification is performed by sharing data between stores. This may also be done by transmitting.

Registered seals may be resealed, but old seals may also be verified, so it is desirable that verification be easy.

(c) Prior Art and Problems Hereinafter, a conventional method will be described using a seal verification machine as an example with reference to FIGS. 1 to 3. FIG. 1 is a perspective view showing the main part of a head of a verification device to which the present invention is applied, FIG. 2 is a schematic explanatory diagram of the verification device shown in FIG. 1, and FIG. 3 is a block diagram showing a conventional method.

As shown in FIG. 1, the light source lamp 3 of the reading section 6
The light irradiates onto the document 1 on which the stamp 2 is written. The irradiated light is not reflected from the vermilion stamp 2, but is reflected from the white parts other than the stamp 2, and the reflected light is focused on the image sensor 5 by the lens system 4. That is, the image of the stamp 2 stamped on the document 1 is projected onto the light receiving surface of the image sensor 5, and the image sensor 5 converts the optical image into verification image data.

As shown in FIG. 2, this collated image data is processed in a data processing section 9, collated with the registered image data read out from the registered file 7, and outputted to an output section 8. (CRT) and printed by a printer if necessary.

To explain the conventional data processing method, in FIG. 3, reference numeral 7 denotes a registration file, which is composed of, for example, a magnetic disk, and stores registered image data such as a seal, together with an account number.

Reference numeral 10 denotes an input image buffer that holds image data read by the image sensor 5 of the reading section 6.

Reference numeral 11 denotes a registered image buffer, which has a function of holding the registered mark indexed from the registration file 7 during verification and sending it to the data calculation processing section 12.

Reference numeral 12 denotes a data calculation processing unit, which has the function of calculating the image center of the input image data transferred from the input image buffer 10, cutting out the image area, and rotating the image. is registered in the registration file 7 of the center 15 via the line control unit 14, and when verifying the seal, the verification image data is compared with the registered image data taken out from the registration file 7 and held in the registration image buffer 11, It has a function of transferring the results to the output section 8 and the line control section 14.

Reference numeral 13 denotes a control section that controls each section.

Reference numeral 14 denotes a line control unit, which has functions of controlling data compression, expansion, and line reception and transmission.

Reference numeral 15 denotes a center, which has a registration file 7 and is connected via a line to the collation machines of a plurality of stores for communication.

With such a configuration and function, when registering a seal, the read image data is stored in the input image buffer 10 and then processed by the data calculation processing unit 12 to calculate the center position and cut out the area. Then, it is stored in the registration file 7 via the line control unit 14 together with the account number input from the keyboard 16.

When performing verification, a pre-registered seal is called up to the registered image buffer 11 using the account number, etc., and then the verification stamp is read by the reading section 6 and stored in the input image buffer 10 as verification image data. The matching image data is subjected to center calculation and area cutting processing in the data calculation processing section 12, and is overlapped with the registered image data transferred from the registered image buffer 11, and matching is performed while rotating the matching image data. The image comparison is displayed on the CRT of the output unit 8 as an overlapping image and matching rate, or printed by a printer.

In this way, registration and verification of seals can be performed.

In such a seal stamp verification machine, a registered seal stamp may be resealed, but even after the resealing, it may be necessary to verify the old seal. That is, for example, when a person in charge of a corporation changes, the seal may be changed, but it may be necessary to check the seals of checks issued before the time of the change.

Conventionally, when it became necessary to carry out the procedure for changing a seal, the user entered an instruction to change the seal and the account number from the keyboard 16, and the new seal to be changed was read by the reading section 6, which transmitted it to the registration file 7, and the process of changing the seal was carried out. It is being done.

However, in order to update the re-seal data for the previously registered Elijah, the image data of the old seal that had been registered until now will be erased.

Therefore, it was impossible for a seal verification machine to output the old seal for purposes such as verification.

In this case, the teller at the financial institution would manually perform the verification by taking out the old seal register and searching for it. Such manual work not only complicates operational work, but also has the drawback of causing a decline in service quality.

(d) Purpose of the Invention The purpose of the present invention is to solve the above-mentioned drawbacks, and to provide a reseal processing method that allows verification of the old seal even after the seal has been resealed.

(e) Structure of the Invention The present invention includes at least one old image file section that stores registered image data of the old seal that has been resealed, and a search means that searches the registered image data of the old seal from the old image file section. This re-sealing processing method is characterized in that when re-sealing, the old image is transferred from the registration file section to the old image file section and held therein, thereby achieving the objective.

(f) Embodiment of the Invention An embodiment of the invention will be described below with reference to FIGS. 4 and 5. FIG. 4 is a block diagram showing one embodiment of the present invention, and FIG. 5 is an explanatory diagram of FIG. 4.

have.

The data analysis unit 18 inputs the new seal image data to the new seal image data registration unit 1 in the case of new registration depending on whether the input by operating the keyboard 16 is new registration or reseal registration.
9, and when resealing, reseal image data registration section 20
It also has a function of starting the registered image data transfer processing section 21.

The new seal image data registration unit 19 stores the newly registered image data in the new seal image data storage unit 1 of the registration file 17.
7a.

The reseal image data registration section 20 has a function of storing reseal registration image data at a location after the image data in the new seal image data storage section 17a is transferred to the old seal image data storage section 17b.

The registered image data transfer processing section 21 has a function of transferring the old seal image data stored in the new seal image data storage section 17a to the old seal image data storage section 17b at the time of seal change.

When a search instruction for registered image data is input using the keyboard 16, the data analysis unit 22 searches the registration file 17 for new seal image data search unit 23, depending on whether the image data is a new seal, a reseal, or an old seal. , the reseal image data search section 24, or the old seal image data search section 25, and has a function of sending out the searched image data to the line.

The new seal image data search section 23, the reseal image data search section 24, and the old seal image data retrieval section 25 respectively search the new seal, reseal, and old seal image data stored in the registration file 17 and send them to the data analysis section 22. It is something to send.

With such a structure and function, when registering a new seal, first add an account number to the index and input it from the keyboard 16, read the seal, and enter the address in the image data section 171, for example in FIG. Register with A.

Next time, when resealing a seal for the same account, transfer the image data in address A to the old seal image data section 174.
For example, at the same time as transferring to address B in the figure, the image data of the new seal that has been resealed is registered at address A.

Further, when searching for old seal registration image data by seal stamp verification or the like, the image data stored at address B is read out and output in response to a search request from the keyboard 16.

In this way, even if the registered seal is resealed, the old seal is stored in a predetermined area of the registration file 17, so the old seal can be verified.

Furthermore, even if the seal is changed again and a plurality of pieces of old seal image data are generated, this can be dealt with by expanding the old seal image data section 174 or adding one more piece. It is also possible to provide a function that allows the old seal image data to be deleted at a certain period of time.

(g) Effects of the Invention As explained above, according to the present invention, when a seal is resealed, it is transferred and stored in the old seal file section provided in the registration file, so there is no need to manually extract and search the seal register. This has the effect that old seals can be easily verified.
