DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a certificate issuing system for issuing (updating / re-issuing) a certificate in a prefecture other than the issuing prefecture and a method of updating the certificate issuing system.

[0002]

2. Description of the Related Art Conventionally, since each prefecture has only imprint data of its own prefecture, a certificate has not been issued in another prefecture, and an actual method of realization has not been established. If it is realized, the following two plans can be considered.

At the time of reception, information (for example, a prefecture type code) indicating which prefecture is located is input by a registration terminal, and imprint data of the prefecture corresponding to the information is printed on a certificate.

[0004] An ID number is provided in the card, and the seal imprint data of the prefecture derived from the ID number is printed on a lighting book.

However, according to the first method,
It is necessary to input information about which prefecture is used at each reception, and there is a possibility that imprints of the wrong prefecture may be printed due to erroneous input.

According to the second method, in the case where the ID number is falsified or misread, there is a possibility that an incorrect imprint is printed.

[0007]

As described above, when issuing a certificate, it is necessary to input the information of which prefecture it is at the time of each reception, and the imprint of the wrong prefecture is printed by erroneous input. There is a problem that an imprint may be printed when the ID number is falsified or misread.

Accordingly, the present invention provides a certificate issuing system capable of preventing an input error when issuing a certificate and correctly issuing a certificate in response to tampering or misreading, and a renewal of the certificate issuing system. The aim is to provide a method.

The registration terminal 3 searches the personal data table shown in FIG. 4B in the host computer 1 by the ID number read by the IC card reader 4 to obtain the imprint type code (ST24) and reads it. The imprint type code portion of the ID number is taken out (ST25).

Then, the registration terminal 3 performs data comparison (comparison) between the imprint type code obtained in step ST24 and the imprint type code extracted in step ST25 (ST
26) If the comparison results are the same, the imprint data corresponding to the imprint type code is read using the imprint data correspondence table shown in FIG. 4C (ST27), and the imprint of the imprint data is reflected. Then, an IC card certificate is created by the certificate issuing machine 5 (ST28). The certificate issuing machine 5 supplies a raw card (IC card for certificate) from the supply unit 6 and uses the IC card reader / writer 7 to
Create

If the imprint data differs in step ST26, the registration terminal 3 displays an error on the registration terminal screen 3a (ST29). Here, the operator inputs from the input device 2 whether or not to continue issuing (ST3).
0).

When an instruction to continue issuance is input, the operator judges the wrong data (the ID number of the IC card or the imprint type code of the personal data table) based on the contents of the application form for updating or reissuing. ) Is changed by the input device 2 and registered (ST31), and the registration terminal 3 creates an IC card certificate in steps ST27 and ST28 described above.

If the issuance is not continued in step ST30, the process ends.

Next, a third embodiment will be described.

FIG. 6 shows a data format according to the third embodiment.

FIG. 6A shows an example of a data format in the IC card certificate C. The IC card certificate C stores an ID number for identifying the applicant and an imprint encryption key for identifying the imprint. In addition, related information such as an address may be stored.

The D number and the imprint encryption key are read (ST42). The read IC card certificate C is discarded (ST43).

The registration terminal 3 searches the personal data table shown in FIG. 6B in the host computer 1 by the ID number read by the IC card reader 4 to obtain the imprint type code (ST44) and reads it. The imprint encryption key is decompressed (decrypted) by the existing encryption software to obtain an imprint type code (ST45).

The registration terminal 3 performs data comparison (comparison) between the imprint type code acquired in step ST44 and the imprint type code extracted in step ST45 (ST11).
46) If the comparison result is the same, the imprint data corresponding to the imprint type code is read using the imprint data correspondence table shown in FIG. 6C (ST47), and certification is performed by reflecting the imprint. An IC card certificate is created by the letter issuing machine 5 (ST48). The certificate issuing machine 5 supplies a raw card (IC card for a certificate) from the supply unit 6 and creates an IC card certificate C using an IC card reader / writer 7.

If the imprint data differs in step ST46, the registration terminal 3 displays an error on the registration terminal screen 3a (ST49). Here, the operator inputs from the input device 2 whether or not to continue issuing (ST5).
0).

When an instruction to continue issuance is input, the operator judges the wrong data (the imprint encryption key of the IC card or the imprint type of the personal data table) based on the contents of the update or reissue application. (ST51), the registration terminal 3 creates an IC card certificate in steps ST47 and ST48 described above.

If issuance is not continued in step ST50, the process ends.

As described above, according to the embodiment of the present invention, since the issuing prefecture information is stored in the certificate,
The operator who receives the applicant from which prefecture can issue the certificate without inputting (consciousness).

Further, by comparing the seal imprint derived from the ID number in the certificate with the seal imprint data, or comparing the seal imprint type code derived from the ID number and the seal imprint type code derived from the seal imprint identification information, It is possible to correct an imprint improperly due to falsification or misreading of the data in the certificate, and print the imprint on the certificate.

Also, by using an IC card,
A system that is strong against data tampering can be constructed.

[0060]

As described in detail above, according to the present invention,
It is possible to provide a certificate issuing system and an update issuing method of the certificate issuing system that can prevent an input error when issuing a certificate and can correctly issue a certificate in response to tampering or misreading.
