Description

The present invention relates to an ID card issuance management system suitable for application to issuance management of cash cards, employee cards, employee cards, membership cards, student cards, alien registration cards, passports, and various driver's licenses. .

In recent years, ID card issuance management systems such as cash cards, employee ID cards, employee ID cards, membership ID cards, student ID cards, alien registration cards, and various driver's licenses with facial photographs have been increasingly used. . For example, an employee card issuance management system is often adopted in a company with a large number of employees such as branch offices straddling prefectures. In this system, a computer is provided at the head office, and the computer for the head office often records and records the violation history of employees assigned to the branch office.

When a person whose expiry date has expired at the branch office applies for the renewal issuance, the person is seconded to the branch office that received the employee ID, and the employee's personal information is sent to the head office computer. Is queried. Here, personal information refers to name, address, date of birth, date of issuance of employee ID card, expiration date, etc. If the employee confirms that the employee is registered at the company headquarters and has no history of violations as a result of the inquiry from the company headquarters, the branch office issues an employee certificate.

Incidentally, the conventional ID card issuance management system has the following problems.

Recently, cash cards, employee ID cards, employee ID cards, membership ID cards, student ID cards, alien registration cards, and various driver's licenses are being transferred to ID cards. In addition, electronic cards incorporating storage means for recording personal information of the cardholder are also being manufactured. However, it may be possible that the face photo is replaced to impersonate someone else and the ID card is illegally issued.

Regarding the personal information of the requesting party such as these various ID cards, the first name in the code table for JIS graphic characters (JISX0208-1983), in particular, “Character Name” is a non-standard character. And when a kanji other than the second level is included, the kanji must be registered as an external character.

This is because an external character cannot be displayed by a normal word processor function or formed by a printer. Such old Chinese characters are often managed by adding character code numbers as external character image information. Therefore, once an external character is registered and placed, when a person including a similar old Chinese character makes a request to issue an ID card, the external character information related to the old Chinese character is provided for that person. Can be used.

In addition, when this type of ID card issuance management system is installed at each hospital in a prefecture by a medical corporation, or at a branch, factory, or affiliated company that is distributed throughout the country by a large corporation, the same external character is used. There are cases where external characters are registered with different character code systems.

This is because it is extremely rare that the ID card issuance system placed in each prefecture is the same manufacturer and model, so each sub-organization factory or branch, printer used for each prefecture hospital, etc. This is because the external character registration function of the information processing apparatus is often different depending on the manufacturer.

Therefore, if the ID card issuance requester's personal information contains Kanji in the old font, and the document issuance requester moves from the branch to another prefecture, the foreign character registration at the branch Despite this being done, other branches and factories will have to re-register external characters for the old kanji from the beginning. As a result, there is a problem in that software resources are wasted, an ID card issuance procedure takes wasted time, and a plurality of registration numbers are assigned to the same character.

Therefore, the present invention solves the above-described problems, and can prevent forgery and alteration of a card and copy it at the time of card update, etc., and even if an external character is included in personal information, a new face image is included. An object of the present invention is to provide a face image forming apparatus, a face image forming method, and an ID card issuance management system that allow easy card issuance.

In order to solve the above-described problems, an ID card issuance management system according to the present invention issues an ID card having a storage means to each cardholder based on the personal identification number. A system to manage,
Storage means for a system for storing at least personal information of the cardholder corresponding to the personal identification number;
Information reading means for reading personal information from the storage means of the ID card;
Control means for comparing and collating the personal information read from the storage means for the system based on the personal identification number and the personal information by the information reading means, and outputting the issuance permission of the ID card based on the result of the comparison and collation It is possible to prevent counterfeiting and copying of the card.

The first issue management system for an ID card according to the present invention is a system for issuing and managing an ID card having a storage means based on the individual identification number, as well as giving an individual identification number to each card holder. And at least a storage means for the system for storing the personal information of the cardholder corresponding to the personal identification number, an information reading means for reading the personal information from the storage means of the ID card, and a system for the system based on the personal identification number. Control means for comparing and collating the personal information read from the storage means and the personal information by the information reading means, and outputting an ID card issuance permission based on the result of the comparison and collation.

According to the first ID card issuance management system of the present invention, when issuing an ID card, personal information of the cardholder corresponding to the personal identification number is read from the storage means for the system. Thus, the personal information is read from the storage means of the ID card by the information reading means. The personal information read from the storage means for this system and the personal information by the information reading means are compared and collated by the control means.

For example, the personal authentication code after the personal identification number read from the storage means of the ID card is encoded by the encoding means and the personal authentication number after the personal identification number read from the storage means of the system is encoded in the same manner Since the code is compared and verified by the control means, the ID permission for issuing the ID card is output by the control means based on the result of the comparison and verification. (In the present invention, a personal identification number such as a license number is referred to as a “personal identification number”, and a code after the personal identification number or the like is encoded and easily collated by a collation system is referred to as a “personal authentication code”. In addition, information attached to the individual such as name, address, date of birth, date of issuance of employee ID, personal identification number ID and its expiration date, personal identification code after encoding the personal identification number, etc. (Indicated as "personal information".)

Therefore, if the personal information read from the storage means for the ID card and the personal information read from the storage means for the system do not match, the ID card issuance permission is not output, thus preventing unauthorized issuance of the ID card. it can.

A second issue management system for ID cards according to the present invention is a system for issuing and managing ID cards having storage means, and a plurality of ID card creation systems for registering external characters in the ID card, and these ID cards. Management means for managing the creation system, the management means has a database for external character registration, and this database is provided with an external character information management table, and the external character information management table is registered in each ID card creation system. With respect to the external characters and the external character information, the external character information of each ID card creation system is subordinate to the same external character registered in the ID card creation system.

According to the second issuance management system for ID cards according to the present invention, for example, the external characters registered in the ID card in each ID card creation system and the external character information are the same handled by these ID card creation systems. Since the external character information management table in which the external character information of each ID card creation system is subordinated to the external characters of the ID card is automatically created as a database, for example, the character code system in which the same external characters are different between the two ID card creation systems Even when registered in the external character information management table, the external character information of the first ID card creation system and the external character information of the second ID card creation system can be unified by the external character information management table.

Therefore, an external character registered in the first ID card creation system is used to create an ID card in the second ID card creation system, and the external character is registered in the second ID card creation system. Even if not, the first ID card registered in the database by accessing the external character information registered in the ID card or the external character information by the first ID card creation system to the database through the management means The character image information of the external characters by the creation system can be obtained by the second ID card creation system together with the management number.

Thereby, it is not necessary to create the external character in the second ID card creation system, and the external character and the external character information can be managed smoothly between the ID card creation systems.

As explained above,

According to the present invention, the face image or characters, symbols, figures, etc. of the card face recorded in the storage means are compared with the actual face pictures, characters, symbols, figures, etc. of the card face. The authenticity of the ID card can be determined. Therefore, it is possible to prevent unauthorized use of personal information such as the face image, address, name, and effective date on the surface of the ID card. In addition, it is possible to prevent duplication of image data relating to such personal information.

According to the ID card issuance management system according to claims 1 to 8 of the present invention, the personal information read from the storage means of the ID card, the personal information read from the storage means for the system based on the personal identification number, Are provided with a control means for outputting ID card issuance permission based on the collation result after comparison.

With this configuration, if the personal information read from the storage means of the ID card and the personal information read from the storage means for the system do not match, the ID card issuance permission is not output. Can be prevented. Further, the invention according to claim 2 and claim 3 can prevent unauthorized issuance by digital data. In particular, the issuance management system according to claim 4 has a protection function when digital image data is falsified by digital watermark. be able to. Further, according to the inventions according to claims 5 to 8, data comparison and collation can be smoothly performed in the system, and illegal issue can be efficiently prevented.

Even if an external character other than the character of the standard level predetermined by the invention according to claims 9 to 12 of the present invention is included in the personal information, the ID card can be issued illegally. Furthermore, according to the ID card issuance management system according to claims 13 to 17, a plurality of ID card creation systems are arranged for each region, and a database for external character registration is provided in the center, and these ID card creation systems.

Is formed. As the material of the image receiving layer 34, a polymer material such as polyester resin, polyvinyl chloride resin, polyvinyl acetal resin, polyvinyl butyral resin, epoxy resin, acrylic resin can be used. Among them, the polyester resin is preferably used from the viewpoint of environment. The image receiving layer is formed by making these resins into powder and dissolving them in a solvent such as isocyanate, applying the resin with a gravure coater or the like, drying it, and volatilizing the solvent.

The layer adjacent to the image receiving layer 34, for example, the film support 31 or the cushion layer 32, is preferably a resin mixed with (containing) a white pigment in order to enhance the image formed on the image receiving layer 34. The present invention is not limited to this. In order to increase the whiteness, a layer provided with a void may be used. This void can provide cushioning properties. Preferred examples of the white pigment include titanium oxide, barium sulfate, and calcium carbonate, but are not limited thereto. A transparent protective sheet 51 is provided on the surface sheet 21 and is protected so as to cover the surface sheet 21 after the face image is formed.

A transparent protective sheet 51 is provided on the top sheet, and is protected so as to cover the top sheet. The top sheet and the protective sheet 51 are bonded together via an adhesive sheet. As the adhesive sheet, a hot melt resin or a heat melt resin having a resin softening point temperature of about 100 ° C. or slightly higher is formed in a film shape.

On the other surface of the card substrate, a back sheet having a thickness of about 100 μm is provided and has a writing layer that can be written with a pen. The writing layer is obtained by diffusing calcium carbonate and silica fine particles in a polyester emulsion. The writing layer is formed in the same manner as the image-receiving layer of the top sheet by dissolving the above-described material with a solvent, applying it with a gravure coater, etc., and drying to evaporate the solvent. In this example, the face image forming method of the employee card 30 has been described. However, the present invention is not limited to this, and a cash card, employee card, membership card, student card, alien registration card, A passport or various driver's licenses are similarly formed.

FIG. 10 is a cross-sectional view showing a sandwich structure example of the employee ID card 30 in which the electronic component 24 is sandwiched between the back sheet 21 and the top sheet 25.

FIG. 11 is a block diagram showing an example of the internal configuration of the IC chip 24A. Since the employee card 30 as the electronic card is a non-contact type, no terminal for information input / output is provided. The IC chip 24A illustrated in FIG. 11 includes a transmission / reception unit 26, a RAM 27, a nonvolatile memory 28, a power generation unit 29, a CPU 38, and a clock generation unit 39.

The above-described antenna body 24B is connected to the transmission / reception unit 26, and receives personal information D2, card surface image data D3, and personal identification number ID modulated into a predetermined modulated radio wave when information is written. This card surface image data D3 is image data obtained by directly capturing an image of the card surface and digitizing it, and is compressed and recorded in the nonvolatile memory 28 in the employee card 30 (second ID card). In this example, the image data recorded in the nonvolatile memory 28 is subjected to image processing by the JPEG method, which is a color still image compression standard.

At the time of reading information, the personal information D2, the card surface image data D3, and the personal identification number ID are modulated into a predetermined modulation signal and transmitted to the antenna body 24B. A RAM 27 is connected to the transmission / reception unit 26, and personal information D2, card surface image data D3, and personal identification number ID demodulated by the transmission / reception unit 26 are temporarily stored, and control data such as an information writing / reading procedure is temporarily stored. The A nonvolatile memory 28 is connected to the RAM 27, and the personal information D2, the card surface image data D3, and the personal identification number ID are recorded. In the example described later, external character information D0 is recorded.

As the nonvolatile memory 28, a read only memory (EEPROM) capable of erasing and writing electrical information is used. Therefore, even when the power is turned off, the personal information D2, the card surface image data D3, and the personal identification number ID are recorded and held in the nonvolatile memory 28.

A CPU 38 is connected to the above-described transmission / reception unit 26, RAM 27, and nonvolatile memory 28, and input / output of the transmission / reception unit 26, RAM 27, and nonvolatile memory 28 is controlled at the time of information writing / reading. For example, when information is read, the personal information D 2, card surface image data D 3, and personal identification number ID read from the nonvolatile memory 28 are output to the transmission / reception unit 26. At the time of writing information, personal information D2, card surface image data D3, and personal identification number ID obtained from the transmission / reception unit 26 are recorded in the nonvolatile memory 28.

A clock generator 39 is connected to the CPU 38, and a system clock for executing an information write / read operation is supplied. A power supply generation unit 29 is connected to the transmission / reception unit 26, the information write / read unit 27, the nonvolatile memory 28, the CPU 38, and the clock generation unit 39. Is received by the antenna body 24B, and a DC power supply VCC generated based on the electromagnetic energy is supplied.

For example, the DC power supply VCC is obtained by rectifying the electromotive force Vφ generated by electromagnetic induction from the card read / write device side. Of course, in addition to this, a method of generating a power source by taking in electric power by high-frequency electromagnetic energy from the outside to the antenna body 24B or another object is also conceivable. Instead of the CPU 38 and the RAM 27, those portions may be configured by a control logic circuit.

Next, an information writing / reading device used for the employee ID card 30 will be described. FIG. 12 is a block diagram illustrating an internal configuration example of the card read / write device 14. A card read / write device 14 shown in FIG. 12 is an example of an information writing / reading device. An IC chip 24A (see FIG. 11) provided in an IC card such as an employee ID card 30 stores personal information D2 of the card user and the card. The surface image data D3, personal identification number ID, etc. are written in or read out. The card read / write device 14 includes a card read / write unit 70 and an information write / read control unit 71. The card read / write unit 70 has a slide part 72 having a concave shape on the card insertion side, and an IC card is slid into the card read / write part 70. Antenna bodies 73 are attached to the left and right sides of the slide portion 72. The antenna body 73 is electromagnetically coupled to the antenna body 24B in the IC card, and personal information D2, card surface image data D3, and personal identification number ID are written or read while supplying driving power to the IC chip 24A in the card. It is.

The information writing / reading control unit 71 includes a transmission / reception unit 74, a RAM 75, a ROM 76, a communication interface 77, a CPU 78, a power supply unit 79, an EEPROM 82, and an image processing unit 83 connected to the internal bus 81. A transmitting / receiving unit 74 is connected to the antenna body 73 of the card read / write unit 70 described above, and personal information D2 or personal identification number ID modulated into a predetermined modulated radio wave is transmitted when information is written. At the time of reading information, personal information D2, card surface image data D3, and personal identification number ID that have been modulated in advance into a predetermined modulation signal in the IC card 30 are taken in via the antenna body 73 and demodulated.

A RAM 75 and a ROM 76 are connected to the transmission / reception unit 74 via an internal bus 81, and personal information D2, card surface image data D3, and personal identification number ID demodulated by the transmission / reception unit 74 are temporarily stored. The ROM 76 stores control data such as information writing / reading procedures.

An image processing unit 83 is connected to the internal bus 81, and image data such as personal information D2, card surface image data D3, and personal identification number ID is compressed when information is written. At the time of reading information, image data such as personal information D2, card surface image data D3, and personal identification number ID is expanded. In this example, image data such as personal information D2, card surface image data D3, and personal identification number ID is subjected to image processing by the JPEG method, and entropy for decoding these compressed and recorded image data. The decryption code is stored in the EEPROM 82 of the device 14. The EEPROM 82 is connected to the internal bus 81.

Further, a communication interface 77 is connected to the internal bus 81, and an external terminal device is connected via a communication line compliant with the RS-232C (or RS-422) communication protocol. Data communication is performed between the card read / write device 14 and the terminal device.

A CPU 78 is connected to the communication interface 77 via an internal bus 81, and inputs / outputs of the transmission / reception unit 74, the RAM 75, and the ROM 76 are controlled at the time of information writing / reading. For example, when information is read, the personal information D2, card surface image data D3, and personal identification number ID obtained from the transmission / reception unit 74 are transferred to an external terminal device or the like via the communication interface 78. At the time of writing information, personal information D2, card surface image data D3, and personal identification number ID transferred from an external terminal device or the like are output to the transmission / reception unit 74.

The information writing / reading control unit 71 is provided with a power source unit 79, and a high frequency signal having a predetermined frequency for driving the IC chip 24A in the IC card is supplied to the antenna body 73. Of course, the DC voltage VCC is supplied to the transmission / reception unit 74, the RAM 75, the ROM 76, the communication interface 77, the CPU 78, the EEPROM 82, and the image processing unit 83.

Next, an example of data compression in the image processing unit 83 will be described. FIG. 13 is a block diagram illustrating an example of data compression in the image processing unit 83. The image processing unit 83 includes a discrete cosine (DCT) conversion unit 63, a quantization unit 64, an entropy encoding unit 65, and a memory unit 66 shown in FIG.

For example, in the discrete cosine transform unit 63 to which the card surface image data D3 is input, the original image such as the employee card 30 is divided into 8 × 8 pixel blocks. DCT calculation is performed for each block. The DCT coefficients of the DC component and AC component obtained by the discrete cosine transform unit 63 are output to the quantization unit 64. In the quantization unit 64, the DCT coefficients of the DC component and the AC component are independently quantized based on the quantization table from the memory unit 66. Here, the luminance signal quantization table and the color difference signal quantization table stored in the memory unit 66 are referred to.

The output of the quantization unit 64 is encoded by the entropy encoding unit 65. Encoding is performed by the Huffman-Modify method or the like. Of the quantized DCT coefficients, the DC component is encoded as a difference value using the DC coefficient of the immediately preceding block as a predicted value. The AC component is encoded after being rearranged by zigzag scanning within the block. As a result, compressed data D31 obtained by compressing the original image such as the employee ID card 30 is obtained from the entropy encoding unit 65. The compressed data D31 is recorded on the IC chip 24A in the employee card 30.

In this example, header information such as an entropy decoding code such as a normal JPEG data format is not added. This is to prevent forgery and alteration and to reduce the amount of information recorded on the IC chip 24A. If the identification code is not added at all, the identification of the other employee ID card 30 will not be added. In this example, only the code number is added to the compressed data D31. The code numbers are associated as symbols of the entropy decoding code, and a plurality of code numbers are prepared in advance. The code number is recorded in the nonvolatile memory 28 in the IC chip 24A together with the compressed data D31, and is used to select one of a plurality of entropy decoding codes on the card read / write device 14 side when reading information. .

Subsequently, an example of data expansion in the image processing unit 83 will be described. FIG. 14 is a block diagram illustrating an example of data decompression in the image processing unit 83. The image processing unit 83 includes an entropy decoding unit 93, a memory unit 96, an inverse quantization unit 94, an inverse discrete cosine transform unit 95, a decoding unit 97, a selector unit 98, and a plurality of entropy decoding code units C1 to Cn. is doing.

The operation at the time of data decompression is performed in a substantially reverse process to the operation at the time of data compression. However, a plurality of decoding control information prepared in advance as a result of decoding the code number as a symbol added to the compressed data D31. One of the entropy decoding codes C1 to Cn is selected and the memory unit 96 is accessed.

For example, the compressed data D31 read from the IC chip 24A in the employee card 30 is input to the entropy decoding unit 93. The code number is input to the decoder unit 97, and the code number is decoded. A selector unit 98 is connected to the output stages of the plurality of entropy decoding code units C1 to Cn, and one of the entropy decoding code units C1 to Cn is selected based on the output of the decoding unit 97. Is made to select. Therefore, for example, a Huffman table or a quantization table is read from the memory unit 96 by the entropy decoding code selected by the selector unit 98.

The compressed data D31 is decoded by the entropy decoding unit 93 based on, for example, a Huffman table, returned to the quantization index by the entropy decoding unit 93, and then inversely quantized by the inverse quantization unit 94. The output of the inverse quantization unit 94 is subjected to inverse DCT transform by the inverse discrete cosine transform unit 95 together with the separately decoded DC component. From the inverse discrete cosine transform unit 95, card surface image data D3 indicating an original image such as the employee ID card 30 is obtained.

As described above, according to the employee card 30 with the electronic component according to the present embodiment, the card surface image data D3 obtained by directly capturing the image of the card surface and digitizing the image is stored in the non-volatile memory in the IC chip 24A of the employee card 30. The authenticity of the employee ID card 30 can be determined by comparing the card image stored in the non-volatile memory 28 and recorded on the non-volatile memory 28 with the actual card image.

Therefore, it is possible to prevent unauthorized use of the employee ID 30 by falsifying the personal information D2 such as the face image, address, name, and effective date on the surface of the employee ID 30. At the same time, it is possible to prevent the card surface image data D3 related to the personal information D2 from being duplicated.

(3) ID card first issue management system as an embodiment FIG. 15 is a block diagram showing a configuration example of an employee card issue management system 200 to which the ID card first issue management system as an embodiment is applied. is there.

In this embodiment, the personal information D2 read from the non-volatile memory 28 of the employee card 30 described above and the personal information D2 read from the storage means for the system are compared and verified based on the collation result. If the personal information D2 read from the nonvolatile memory 28 of the employee card 30 and the personal information D2 read from the storage means for the system do not match, The ID card issuance permission is not output, so that unauthorized issuance of the ID card can be prevented.

In this example, image data obtained by digitizing characters together with the cardholder's face image is stored in the storage means for the system or the storage means of the ID card. For example, the image data is stored in the storage means for the system or the storage means of the ID card in the vector data format.

The employee card issuance management system 200 shown in FIG. 15 is an example of a first ID card issuance management system, and a personal identification number ID is assigned to each of the card holders 20 (hereinafter also referred to as issuers). In addition, the employee ID card 30 having the nonvolatile memory 28 is issued and managed based on the personal identification number ID.

The system 200 has a data bus 8. A card read / write device 14 as information reading means and information writing means is connected to the data bus 8, and personal information D 2 is written into the nonvolatile memory 28 of the employee card 30, or from the nonvolatile memory 28. Personal information D2 is read out.

Regarding this personal information D2, the name, address, date of birth, date of issuance of the employee card, personal ID number and its expiration date, personal ID number, etc. recorded on the surface of the employee ID card 30 are recorded. It is a personal authentication code after encoding. When the ID card is a driver's license or the like, the license number, reference number, description items, license conditions, and the like. Regarding the employee ID card 30 in this example, image data obtained by taking an image of the card surface is recorded in the nonvolatile memory 28 in a bitmap format (third ID card).

In this example, the card face image, characters, symbols, and figures recorded in the nonvolatile memory 28 are compared with the actual card face image, characters, symbols, figures, and other images. Made. As a result, the authenticity of the employee ID card 30 can be determined, and the personal information D2 such as the face image, address, name and effective date on the surface of the employee ID card 30 can be altered and used illegally. Can be prevented. In addition, it is possible to prevent the card surface image data D3 related to the personal information D2 from being duplicated.

Further, personal information D2 of the issuer 20 is recorded in the nonvolatile memory 28, and a part of the personal information D2, for example, kanji information of external characters (missing characters) is stored in the nonvolatile memory 28 in a bitmap format. To be recorded. Of course, the external character information D0 after converting the external character into the vector data format may be recorded in the nonvolatile memory 28. This external character registration will be described with reference to FIG.

Further, when the personal identification number ID of the issue requester 20 is read from the employee card 30 by the card read / write device 14, the personal information D2 is confirmed using the personal identification number ID of the issue requester 20 as an address. An imaging device (imaging means) 15 is connected to the card read / write device 14 via the data bus 8, and based on the personal information D2 of the issuer requester 20 by the employee card 30 read by the card read / write device 14. The face image data D1 is output after imaging the face part of the issuer 20. A filing device 16 as a storage means for the system is connected to the camera 11 through the data bus 8, and the face image data D1 and personal information D2 of the issue requester 20 corresponding to the personal identification number ID are stored in a text format.

For example, the filing device 16 is assigned a memory area for a face image and a memory area for personal information. In the former memory area, the face image data D1 of the issuance requester 20 obtained by photographing the face part of the issuance requester 20 of the employee card 30 by the camera 11 is stored with the personal identification number ID of the issuance requester 20. Stored as an address. Similarly, the personal information D2 of the issue requester 20 is updated and stored in the latter memory area.

Card creation means 18 is connected to the filing device 16 via the data bus 8, the face image data D1 of the issue requester 20 obtained from the camera 11, and personal information of the issue requester 20 by the card read / write device 14. The face image of the issue requester 20 and personal information D2 are formed on the basis of D2 and the issue permission by the computer 55, and a new employee card 30 in which the personal information D2 of the issue requester 20 is written Created. An example of the employee card printer will be described with reference to FIG.

The computer 55, the application form scanner 12, and the terminal device 57 are connected to the data bus 8 described above. An application form scanner 12 having a character recognition function (OCR) is used. This is because, when the personal information D2 is recorded in the bitmap format in the nonvolatile memory 28 of the employee ID card 30, the personal information D2 read from the nonvolatile memory 28 is converted into text-format character information. It is.

Further, when the personal information D2 in the vector data format is recorded in the nonvolatile memory 28 of the employee ID card 30, the personal information D2 in the vector data format read from the nonvolatile memory 28 is converted into a bitmap, and then the individual information D2 is recorded. Information D2 may be converted into character information by OCR.

The application form scanner 12 may be used to read the personal identification number ID of the issuance requester 20 described in the issuance application form 40 when the employee card is created. The terminal device 57 is operated by the operator to input the description items when the description items are changed when the employee card 30 is issued or updated. In the computer 55 as a control means, the personal information D2 read from the filing device 16 based on the personal identification number ID and the personal information D2 read from the employee card 30 by the card read / write device 14 are compared and collated. Based on the result of this comparison and collation, the photographing permission is output from the computer 55 to the camera 11, and the issuance permission of the employee ID card 30 is output from the computer 55 to the card creation means 18.

In this example, after reading image data such as face images and character information from the non-volatile memory 28 or the filing device 16, the computer 55 checks the alignment of the image data, and then aligns the image data with a predetermined alignment or more. If there is a possibility, an ID card issuance permission may be output. For example, when the image data in the nonvolatile memory 28 is partially altered, the alignment of the image data is lost. Therefore, a protective function such as “digital watermark” can be provided.

Further, in the case where the personal identification information ID is recorded in the nonvolatile memory 28 of the employee card 30 and the filing device 16, an encoder 23 is provided as an encoding means for encoding the personal identification number ID. The personal authentication code after encoding the personal identification number ID read from the memory 28 and the personal authentication code after encoding the personal identification number ID read from the filing device 16 are compared and collated by the computer 55.

For example, when both personal authentication codes match, a permission for photographing to the camera 11 and a permission for issuing to the card creation means 18 are output. If the two personal authentication codes do not match, the photographing permission to the camera 11 and the issuance permission to the card creating means 18 are not output. Therefore, when the personal identification number ID is tampered with, the employee ID 30 Can not be issued.

The camera 11 that has received the photographing permission from the computer 55 takes a face image of the issue requester 20. Further, the card forming means 18 forms an image of the face image of the issue requester 20 and the personal information D2 of the issue requester 20 on the card board based on the face image data D1 of the issue requester 20 and the personal information D2. Is done. Therefore, a new employee card 30 can be issued to the issue requester 20 reliably and smoothly.

In this example, an update application is used as the issue application 40 when the employee card 30 having the nonvolatile memory 28 is updated and issued. In this case, an application form printer 37 as information recording means is connected to the data bus 8, and the personal information D2 of the card renewer is recorded in the update application form. At this time, if an external character other than a character of a predetermined standard level is included in the personal information D2, the external character information D0 in the bitmap format or the vector data format read from the nonvolatile memory 28 of the employee card 30 is stored. Based on this, the external characters are recorded in the renewal application form.

In addition, when the communication modem 17 is connected to the data bus 8 and the employee card issuance management system 200 is arranged in a prefecture or the like to operate the employee card issuance management on a nationwide scale, Used when communicating with employee card issuing systems in other prefectures.

Subsequently, a configuration example of an employee card printer used in the employee card issuance management system will be described. FIG. 16 is a conceptual diagram showing a configuration example of the employee card printer 6 as an example of the card creation means 18. In this example, a case where a sheet-like protective sheet 51 is formed on one raw card substrate 30 for an employee card will be described.

The employee card printer 6 shown in FIG. 16 has a card supply means 60 and a protective sheet applying unit 50. The card supply means 60 has a first conveyor belt device 41. A raw card supply unit 42 is provided at one upper end of the conveyor belt device 41. In order to write the personal information D2 of the issue requester 20 in the raw card supply unit 42, a plurality of raw card substrates 30 for employee IDs that have been cut into pieces in advance are face-up areas facing upward. It has been stocked. In this example, the raw card substrates 30 are automatically supplied so as to be dropped from the raw card supply unit 42 to the conveyor belt device 41 one by one.

The raw card substrate 30 on the conveyor belt device 41 after the automatic supply is conveyed from the left side to the right side. An image forming unit (printer) 43 is provided on the conveyor belt device 41. While the raw card substrate 30 is moved from the left side to the right side, the name of the issue requester 20 and the employee certificate are issued in the predetermined area P3. The date and the like are recorded, and the face image of the issue requester 20 is formed in the image forming area P4.

An information writing unit 44 such as the card read / write device 14 described above is provided on the downstream side of the conveyor belt device 41, and the personal information D2 of the card user is stored in a text format or raster format on the IC chip 24A in the employee card. Or written in vector format. In this example, external character information D0 and card surface image data D3 are also written.

An image check unit 46 is provided on the downstream side of the information writing unit 44 with the first drive roller 45 interposed therebetween, and the user's face photograph formed by the image forming unit 43, name, card issuance date, etc. are incorrect. It is checked whether it is not. An information check unit 48 is provided on the downstream side of the image check unit 46 with the second drive roller 47 interposed therebetween, and it is checked whether the personal information D2 written to the IC chip 24A by the information writing unit 44 is incorrect. .

A second conveyor belt device 49 is provided on the downstream side of the information check unit 48. In this example, the raw card board 30 on which the personal information D2 is written is conveyed from the left side to the right side. A protective sheet applying unit 50 is provided on the conveyor belt device 49, and a film-like protective sheet 51 is supplied to the raw card substrate 30 '.

In this example, the protective sheet 51 includes a laminate film laminated in a sheet shape (cut sheet shape), and the laminate film has an adhesive sheet (not shown) on one surface. Of course, the protective sheet 51 may be a roll of a laminate film.

Further, the protective sheet 51 is not limited to a laminate film, and a sheet obtained by winding a hot stamp film in a roll shape or a sheet obtained by laminating a hot stamp film in a cut sheet shape can be used. The protective sheet applying unit 50 is provided with a vacuum hot press device 52, which receives the raw card substrate 30 'from the card supply means 60 and the protective sheet 51 from the protective sheet applying unit 50, and the raw card substrate 30' and its The protective sheet 51 is pasted together via an adhesive sheet (not shown). At this time, the paper sheet on the adhesive sheet is peeled off and wound up as a waste paper.

The vacuum hot press device 52 has a flat press portion disposed on the conveyance path, and a predetermined pressure is applied from above the protective sheet 51. Therefore, the press part can be moved in the vertical direction. The press section is provided with an electric heater (not shown) so as to heat the protective sheet 51 and the raw card board 30 'to a predetermined temperature.

In this example, although depending on the kind of the adhesive sheet, the heating temperature is about 40 ° C. to 120 ° C., and the heating time is about 10 seconds to 120 seconds. This adhesive sheet melts when heat is applied and solidifies when it cools. The apparatus for heating and bonding the protective sheet 51 is not limited to the vacuum hot press apparatus 52, and may be a normal hot press or a heat roller apparatus. In addition, a cooling unit 53 is provided on the downstream side of the vacuum hot press device 52, and the heated card board 30 'is cooled. Thereby, the new employee ID card 30 protected by the protective sheet 51 is completed.

Next, the authenticity determination operation of the personal information D2 handled by the employee card issuance management system 200 will be described.

FIG. 17 is a flowchart showing an example of authenticity determination of the personal information D2 handled by the employee card issuance management system 200. In this example, personal information D2 in text format, raster format, or vector format is recorded in the non-volatile memory 28 of the employee ID card 30, and the personal information D2 read from the non-volatile memory 28 and filing It is assumed that when the personal information D2 read out from the device 16 does not match, the issue permission of the employee card 30 is not output.

On the premise of this, the personal information D2 is read from the nonvolatile memory 28 by passing the employee card 30 through the card read / write device 14 in step B1 of the flowchart shown in FIG. Thereafter, in step B2, it is determined whether the personal information D2 is in text format or not. The determination at this time is performed by identifying a flag indicating a data format, which is generally performed. If the personal information D2 is in text format, the process directly proceeds to the comparison process in step B8.

If the personal information D2 is not in the text format, the process proceeds to step B3 to determine whether the personal information D2 is in the raster format or not. If the personal information D2 is in the raster format, the process proceeds to step B6 and character recognition processing is executed by the scanner 12 with the character recognition function in order to convert it into the text format. If it is not in the raster format, the process proceeds to step B4, raster processing is performed, and then the process proceeds to step B6. In step B6, the personal information D2 after raster processing is character-recognized by the scanner 12, and the raster-format personal information D2 is converted into text-format personal information D2.

In parallel with Step B2 to Step B6 described above, in Step B7, the filing device 16 is accessed by the computer 55, and the personal information D2 in text format is read out. Thereafter, in step B8, the text-format personal information D2 read from the nonvolatile memory 28 of the employee ID card 30 is compared with the text-format personal information D2 read from the filing device 16.

For example, the personal identification code after the personal identification number ID read from the non-volatile memory 28 of the employee card 30 is encoded by the encoder 23 and the personal identification number ID read from the filing device 16 are encoded in the same manner. The computer 55 compares and verifies the personal authentication code later.

As a result of this comparison and collation, if the two match, the computer 55 outputs a permit for issuing the employee card 30 in step B9. This issuance permission is output to the camera 11 and the card creation means 18. If they do not match at step B8, the process goes to step B10 and the person in charge performs an abnormality detection process. For example, the person in charge notifies the issuance requester 20 that the personal information D2 is different, or takes measures such as inquiring about the cause of the difference.

Thereafter, in step B11, it is determined whether or not the authenticity determination process for all employee certificates 30 has been completed. When the authenticity determination process is not completed, the process returns to step B1 to execute the authenticity determination process of the other employee ID card 30, and the above steps are repeated. When the authenticity determination process for all employee certificates 30 is completed in step B11, the control is terminated.

As described above, according to the employee certificate issuance management system 200 according to the first embodiment, when the employee certificate 30 is issued, the personal information D2 of the issue requester 20 corresponding to the personal identification number ID is filed. On the other hand, the personal information D2 is read from the non-volatile memory 28 of the employee card 30 by the card read / write device 14. The personal information D2 read from the filing device 16 and the personal information D2 of the employee card 30 by the card read / write device 14 are compared and collated by the computer 55.

Therefore, if the personal information D2 read from the nonvolatile memory 28 of the employee card 30 and the personal information D2 read from the filing device 16 do not match, the issuance permission of the employee card 30 is not output. Unauthorized issuance of the certificate 30 can be prevented.

Next, the external character information D0 handled by the employee card issuance management system 200 will be described. FIG. 18 is an image diagram showing a display example of the external character “blue” in the bitmap format handled by the employee card issuance management system 200.

In this example, the personal information D2 of the issuer 20 includes an external character (missing character) other than a predetermined standard character such as JIS, and the external character is converted into a bitmap format. The external character information D0 is recorded in the non-volatile memory 28 of the employee ID card 30, and the external character information D0 is also registered in the filing device 16. For example, “blue” of the external character (old font) in the bitmap format shown in FIG. 18 has a horizontal character size of X1 and a vertical character size of Y1. In this case, when the size of one character is represented by the number of vertical × horizontal pixels, it is, for example, 16 × 16 bits. Of course, it is better to increase the number of pixels when forming external characters with high definition.

FIG. 19A and FIG. 19B are image diagrams showing a format example of the external character information D0 handled by the employee card issuance management system 200. FIG. In this example, the issuer code indicating the issuer who registered the external character information D0 is subordinate to the external character information D0 and recorded in the nonvolatile memory 28 of the employee card 30, the filing device 16, or the like.

For example, an external character such as “blue” in the above-described old character form is formed as external character bitmap data shown in FIG. 19A, and an external character code (hereinafter simply referred to as an external character code and an issuer code is added as header information). The information D0 is composed of an external character code and an issuer code) and external character bitmap data. As for this external character, how to read it may be recorded in the nonvolatile memory 28 or the like depending on the external character information D0. When the character sizes X1, Y1, etc. shown in FIG. 18 are defined, the character sizes X1, Y1 may be added to the data format of the external character information D0 shown in FIG. 19B.

In this way, the registered items up to the character size of the external character are different in each prefecture when the employee card issuance management system 200 is arranged in a prefecture and the employee card issuance management is operated on a nationwide scale. This is because even when an image processing apparatus of a different type is used, the size of the external characters can be unified, and for this reason, the external character information D0 can be unified nationwide.

(4) ID card second issuance management system as an embodiment FIG. 20 is a configuration example of an employee card issuance management system 300 with a font server to which the ID card second issuance management system as an embodiment is applied. FIG.

In this embodiment, at least a prefectural unit according to a prefecture unit is arranged, and a database for external character registration is provided in the center, and different characters are used for the same external characters handled by these employee card preparation systems. Even when registered in the code system, the external character information D0 related to the external characters can be unified by referring to the external character information management table in which the registration information of each employee ID creation system is subordinated. A system for centrally managing the external character information D0 at the center can be automatically constructed.

In this example, when external character information is registered in the external character registration database and a new character code is assigned to an external character for which no character code is specified, the system code for registering the external character information After changing to, it will be registered in the database.

An employee card issuance management system 300 with a font server shown in FIG. 20 is a system for issuing and managing an employee card 30 having a non-volatile memory 28. The employee personal information D2 is stored in the non-volatile memory 28. This is a system for issuing and managing an employee ID card 30 that is recorded and a facial photograph of the person is formed.

In this employee card issuance management system 300, an employee card creation system SPi (i = 1 to n) with an external character registration function is arranged for each prefecture. In this example, the head office that centrally manages the external character information D0 is provided with a font server 81 as a management means, and the external character information D0 of the employee card creation system SPi (i = 1 to n) arranged in each prefecture is unified. It is made to manage. Each employee card creation system SPi has a function of registering external characters to the employee card 30.

The font server 81 has a control device 31 and an external character registration database 32, and the database 32 is connected to the control device 31 through the data bus 9. In order to automatically construct an external character information management table, the control device 31 performs write control of external character information D0, extraction processing of the same external character using the totaling process and learning function, and the like. The read control of the external character information D0 is performed with respect to the access from each employee ID creation system SPi.

The aforementioned database 32 is provided with an external character information management table. The external character information management table relates to the external characters registered in each employee ID creation system SPi and the external character information D0, and creates each employee ID for the same external character registered in each employee ID creation system SPi. This is made by subordinate the external character information D0 of the system SPi. In this example, a new character code, an old code related to an external character, and an old issuer code indicating the issuer that registered the external character last time are recorded in the database 32.

Furthermore, a new character code is assigned to an external character for which no character code is defined, and the old code related to the external character in the employee ID card 30 is rewritten to a new character code, and the external character of the new character code is changed to a bit. After conversion to the map format or the vector data format, the external characters are registered in the database 32.

The employee card issuance management system 200 described above is applied to each employee card creation system SPi, and a data bus 8 based on a communication protocol such as a LAN is provided therein. The card read / write device 14 is connected to the data bus 8, and personal information D <b> 2 is written into the nonvolatile memory 28 of the employee card 30, or personal information D <b> 2 is read from the nonvolatile memory 28.

In this example, the external character information D0 is registered by a method added to the personal information D2. When a new external character is registered, a new character code and an issuer code indicating the issuer are recorded in the nonvolatile memory 28 of the employee card 30. On the contrary, the character code and the issuer code related to the external character information D0 recorded in the non-volatile memory 28 of the employee ID card 30 are recorded in the database 32.

Further, a filing device 16 for personal information is connected to the data bus 8, and at least employee personal information D2 obtained regarding the issuance of the employee card 30 is recorded. In this example, if the personal information D2 includes an external character other than a character of a predetermined standard level, the external character information D0 is registered from the filing device 16 into the database 32 at the head office.

A terminal device 57 and a scanner 12 having a character recognition function are connected to the filing device 16 through the data bus 8, and the personal information D2 of the employee is read, and the personal information D2 is recorded on the filing device 16 or recorded. When the contents are changed, the recorded contents are rewritten.

Further, an employee card printer 6 as a card making means is connected to the data bus 8, and if there is no change in the personal information D 2 described on the employee card 30, the employee is based on the personal information D 2 by the filing device 16. When the personal identification D30 is created and the personal information D2 is changed, the employee identification 30 is created based on the personal information D2 after the scanner 12 or the terminal device 57 rewrites the recorded contents of the filing device 16.

In this example, an update application is used when the employee card 30 having the non-volatile memory 28 is updated and issued, and the application printer that records the personal information D2 of the card updater in the update application 37, and when external characters other than characters of a predetermined standard level are included in the personal information D2, the external character information D0 in the bitmap format or the vector data format read from the nonvolatile memory 28 of the employee card 30 is included. Based on this, the external characters are recorded in the renewal application form.

In addition to the above, the data bus 8 is connected to the camera 11, the communication modem 17, the encoder 23, the computer 55, the terminal device 57, and the like. The camera 11 is used when photographing a face image to be formed on the employee ID card 30. When the external information is included in the personal information D2 described on the employee ID card 30, the terminal device 57 is used when creating character image information of the external character.

The encoder 23 is used to determine the authenticity of the personal information D2. For example, the encoder 23 encodes the personal identification number ID read from the non-volatile memory 28 of the employee ID card 30 to output a personal authentication code, or encodes the personal identification number ID read from the filing device 16 to encode the personal authentication code. Is output. In the computer 55, both personal identification codes are compared and collated, and the authenticity of the personal information D2 is determined.

The communication modem 17 is used when communicating with the font server 81 at the head office and the employee ID creation system SPi in other prefectures. This is because these employee ID creation systems SPi are often distributed and arranged throughout the country and are connected to the font server 81 of the head office through a communication line 67 such as a public telephone line.

Next, the external character registration table for each prefecture, which is the basis of the external character information management table, will be described first. FIG. 21 is an image diagram showing a recording example of the A character external registration table. In each employee ID creation system SPi shown in FIG. 21, when the personal information D2 of the employee includes an external character other than a character of a predetermined standard level, the external character is stored in the individual employee ID 30. External characters are registered in the non-volatile memory 28 and the filing device 16 for personal information. The filing device 16 creates an external character registration table.

For example, in the record example of the external character registration table for prefecture A shown in FIG. 21, if the prefecture code (A) is assigned as the unique issuer code from the head office to the employee card creation system SP1, the prefecture code ( An external character registration table in which character image information of external characters and their character code numbers are subordinate to A) is created. In this example, for the personal information (name) “Aoyama”, “blue” (JIS ward point 1184) of the old Chinese character number 9892 is used instead of “blue” (JIS ward point 3236) of the Chinese character number 1612. The old font “blue” cannot be registered using the normal word processor function.

Also, regarding the personal information (name) of “Kurokawa”, the “Kuro” (JIS point 11912) of the old Chinese character number 10326 is used without using the “Black” (JIS point 2585) of the Chinese character number 1657. In this case, it is not possible to register “black” of the old font using the word processor function.

Therefore, using the external character registration function, the old characters “blue” and “black” are created as character images on the display screen of the terminal device 57, and the character image of the external character “blue” with respect to the registration number No 1, for example, The character code No = a11 is registered in the external character registration table and is also registered in the non-volatile memory 28 of the employee card 30 possessed by the issuer 20 of “Aoyama”. Similarly, a character image of the external character “black” and its character code No = a12 are registered in the external character registration table for the registration number No. 2 and the non-volatile of the employee card 30 possessed by the issuer 20 ′ of “Kurokawa”. Registered in the memory 28.

Next, the external character information management table will be described. FIG. 22 is an image diagram of an external character information management table in the font server 81. The external character information management table shown in FIG. 22 is automatically aggregated with respect to the external characters registered in each employee card creation system SPi and the external character information D0, and the same registered in each employee card generation system SPi. The external character information D0 of each employee card creation system SPi is subordinated to the external characters, and the external character information D0 is unified. This is to enable mutual reference to each employee ID creation system SPi.

For example, No. for m external characters collected from the external character registration table of each prefecture, “blue”, “black”. 1 to No. In order up to m, management numbers unique to the system are assigned. 1-No. The external character is registered so that the character image information of the “external character” and the prefecture code as the issuer code of the employee ID creation system SPi using the external character are subordinate to m.

In this example, the prefecture code (A) for A prefecture where the old character “blue” was registered as an external character, the prefecture code (C) for C prefecture, the prefecture code (D) for D prefecture, The prefecture code (E) is given. In addition, a prefecture code (A) is given to A prefecture where the old character “black” is registered as an external character, a prefecture code (B) is given to B prefecture, and a prefecture code (G) is given to G prefecture. In the same manner, a prefecture code (K) is given to the K prefecture that registered the old character “Yori” as an external character.

A character code No. is registered in the lower column of each prefecture code. “Blue” in prefecture A is character code No = a11, “blue” in prefecture C is character code No = c11, “blue” in prefecture D is character code No = d11, “blue” in prefecture E is character code No == The character code system is registered in various ways such as e11. Although it is desirable to register the character code No. uniformly in each prefecture, at present, the external character registration function such as a personal computer is not unified by the manufacturer. In this example, “black” in prefecture A is registered with character code No = a12, “black” in prefecture B is registered with character code No = b11, and “black” in prefecture G is registered with character code No = g11. Similarly, “Yori” of K prefecture is registered with the character code No = k11.

For example, regarding the personal information D2 including the external character “black” registered with the character code No = a12 in the A prefecture, the personal information D2 is used in the B prefecture and the employee ID 30 is used. In the case of B, the font server 81 is accessed with the prefecture code (A) and the character code No = a12 as the address in the prefecture B, and the character code No = b11 of “black” in the prefecture B is obtained. is there. In prefecture B, the employee code 30 can be issued using the character code No = b11 of “black”.

In this example, the external character information D0 is recorded on the employee card 30, and the unique character of the system 300 is based on the font data, character code, and issuer code of the external character recorded on the employee card 30. Reference font data, reference character codes, and reference issuer codes may be defined. When the employee card 30 is updated, the reference font data, the reference character code, and the reference issuer code of the unique external characters defined by the system may be recorded in the nonvolatile memory 28 of the employee card 30.

FIG. 23 is an image diagram showing an example of an edit format of the external character information D0 handled by the employee card issuance management system 300. In this example, when m (i = 1 to m) types of external character bitmap data m are recorded in the database 32, the external character information based on the n external character codes 1 to n and the issuer codes 1 to n. D0 is managed by the computer 55 and the control device 31. The computer 55 is provided with a pointer (register) (not shown). When the pointer 1 is given to the external character code 1 and the issuer code 1, the pointer 1 points to the external character bitmap data 1. When the pointer 2 is given to the external character code 2 and the issuer code 2, the pointer 2 points to the external character bitmap data 2.

Of course, the external character bitmap data 1 may be rewritten by the pointer 2. Further, when the pointer 3 is given to the external character code 1 and the issuer code 2, the pointer 3 may indicate the external character bitmap data i. Thereby, one external character information management table can be mutually referred from a plurality of employee card creation systems.

FIG. 24 is an image diagram showing a cross-reference example of another editing format of the external character information D0 handled by the employee card issuance management system 300.

In this example, when one external character bitmap data m is designated, an attribute is given to a pointer that designates the external character bitmap data m. For example, pointer 1 is given to external character code 1 and issuer code 1, pointer 2 is given to external character code 2 and issuer code 2, and pointer 3 is given to external character code 3 and issuer code 3 In both cases, the pointer 1 is pointed to the pointer 2 and the pointer 2 is pointed to the pointer 3 when the external character bitmap data 1 is pointed.

Thus, when one external character information management table is mutually referred from a plurality of employee ID creation systems SPi, etc., the other external character bitmap data m is registered with the same external character bitmap data m. The employee ID creation system can be recognized in a short time.

Next, a case will be described in which external character information D0 is managed and unified among all employee ID card creation systems SPi. FIG. 25 is a flowchart showing an example of unified management of external character information D0 handled by the employee card issuance management system 300.

In this example, a new character code is assigned to an external character for which no character code is defined, the old code related to the external character in the employee card 30 is rewritten to a new character code, and the external character of the new character code is bit It is assumed that external characters are registered in the database 32 after conversion to the map format or vector data format.

In addition, when an external character having the same font design as the external character information D0 recorded in the nonvolatile memory 28 of the employee ID card 30 is already registered in the database 32 as the external character information D0, the external character registered in the database 32 is stored. The font data, character code, and issuer code are recorded on the employee ID card 30.

In this example, the external character information D0 is registered by a method added to the personal information D2,
When updating the employee ID card 30 with the employee ID card registration system SP2 of the prefecture in relation to the employee ID card 30 registered with the external character in the other prefecture employee ID card generating system SP1,
If the registered contents are different between the employee ID creation system SP1 of another prefecture and the employee card creation system SP2 of the prefecture with the same external character, and
Description will be made assuming that the external character information D0 recorded in the employee card 30 with the same external character is different from the external character information D0 recorded in the database 32.

On the premise of this, in step C1 of the flowchart shown in FIG. 25, the issue of the employee card 30 is accepted in the employee card creation system SP2 of the prefecture. Here, the person in charge may receive an update application form from the issue requester 20. Thereafter, the personal information D2 is read from the employee card 30 using the card read / write device 14 in step C2.

In step C3, the computer 55 determines whether or not the personal information D2 includes an external character (missing character). At this time, it is determined whether or not an external character (missing character) is included by finding external character information D0 added to the personal information D2 in another prefecture. From this condition, this corresponds to the case where the external character information D0 is registered in the employee ID card 30, so the process proceeds to step C4.

In step C4, it is determined whether or not the issuer code related to the external character information D0 in the employee card 30 is the same as the issuer code of the prefecture (hereinafter referred to as a new issuer code). At this time, the two codes issued by the computer 55 are compared, and in the case of the condition, both codes do not match. Therefore, even if the issue requester 20 does not make a self-declaration, the employee certificate 30 brought by the person is provided. It is found that the issuer of is an employee card creation system SP1 in another prefecture.

When the conditions in this example are met, the issuer code in the employee card 30 and the new issuer code are different, so the process proceeds to step C5 to determine whether or not there are external characters of the same font in the database 32. To do. At this time, the external character font of the employee card 30 brought by the issuer 20 and the external character font managed in the database 32 are compared by the computer 55 by pattern recognition or the like. If there is an external character of the same font, it is recognized that there is an external character that is the same as the external character created by the employee ID creation system SP1 in another prefecture, although the issuer code is different.

If there is no external character with the same font under the above conditions, the process proceeds to step C6 to register the external character in the prefecture. Thereafter, the process proceeds to step C7, where an external character information management table (file) of the database 32 is created. In this database 32, an external character information management table in which the external character information D0 of each employee card creation system is subordinated to the same external character is automatically created. The external characters of the new character code are registered in the database 32 after being converted into the bitmap format or vector data format.

If an external character of the same font is present in the database 32 in step C5, and after creating an external character information management table for the external character in step C7, the process proceeds to step C8 and the external character information D0 is read from the database 32. . This external character information D0 is composed of font data, character code, and issuer code of the external character. Thereafter, the old code related to the external character in the employee card 30 is rewritten to a new character code, and the external character information D0 of the new issuer code is updated and registered in the employee card 30. The external character of the new character code is recorded in the nonvolatile memory 28 of the employee card 30 after being converted into a bitmap format or vector data format.

Therefore, if the external character is not registered in the above step C3, and if the external character is the same font and the issuer code in the employee card 30 is the same as the new issuer code in step C4, the employee ID Since it is not necessary to rewrite the recorded contents of No. 30, the process proceeds to Step C9, and a new employee card 30 using the employee card printer 6 or the like is created.

Thereafter, the process proceeds to step C10, where, for example, it is determined whether or not the issue management of all employee certificates 30 on the day has been completed. If the issue management has not been completed, the process returns to step C1 to repeat the above steps in order to execute issue management of other employee ID cards 30. If all the issue management of the employee certificate 30 on the day is finished in step C11, the control is finished.

As described above, according to the employee card issuance management system 300 according to the present embodiment, the external characters registered in the employee card 30 and the external character information D0 of the external characters registered in the employee card creation systems SP1 and SP2, respectively. The external character information management table in which the external character information D0 of each of the employee card generating systems SP1 and SP2 is subordinated to the same external character handled by the employee card generating systems SP1 and SP2 is automatically made into a database.

Therefore, for example, even when the same external characters are registered in different character code systems between the two employee card creation systems SP1 and SP2, the external character information D0 of the employee card generation system SP1 and the employee ID are related to the external characters. The external character information D0 of the creation system SP2 can be unified by the external character information management table. It is possible to make a transition in the direction of gradually eliminating work such as new registration.

As a result, the external character registered in the employee card creating system SP1 is used to create the employee card 30 in the employee card creating system SP2, and the external character is registered in the employee card 30 generating system. Even if not, it is registered in the database 32 by accessing the external character information D0 registered in the employee ID 30 or the external character information D0 by the employee ID creation system SP2 to the database 32 through the font server 81. The character image information of the external characters by the employee card creating system SP2 can be obtained by the employee card creating system SP2 together with the management number unique to the system.

Therefore, it is not necessary to create the external character by the employee card creating system SP2, and the external character and the external character information D0 can be managed smoothly between the plurality of employee card creating systems SP1 and SP2. Moreover, even if the same external characters handled in the employee ID creation systems SP1 to SPi arranged in each prefecture are registered with different character code systems, By referring to the external character information management table to which the registration information is subordinated, it is possible to unify the registration information related to the external character nationwide in the future. At the same time, it is possible to automatically construct a system for centrally managing the external character information D0 at the center.

In this embodiment, the case where the font server 81 is provided in the center has been described. However, the present invention is not limited to this. For example, a plurality of font servers 81 are provided, and external character information can be referred to between the plurality of font servers 81. In order to achieve this, different issuer codes may be subordinately assigned to the same external character font, and the corresponding external character font may be referred to from the issuer code.

In this embodiment, the case of the employee card 30 for the ID card has been described. However, the present invention is not limited to this, and a cash card, employee card, membership card, student card, alien registration card, passport or various driver's licenses, etc. The present invention can also be applied to.
