Abstract

Authentication verifying for an object to be certified is carried out. An authentication verifying chip in which authentication verifying information is stored is mounted non-removably on a certificate. A confirmation chip in which the authentication verifying information is encrypted by a crypt key of a certificate issuer and is stored is mounted non-removably on the object to be certified. When verifying the authenticity of the object to be certified, the encrypted authentication verifying information in the confirmation chip is decrypted by the crypt key of the certificate issuer, and it is compared to the authentication verifying information in the authentication verifying chip.

Claims

1. An authentication verifying system, comprising:

a set of a certificate and an object to be certified;

said certificate being mounted non-removably an authentication verifying chip, where copy-unable first authentication verifying information is stored; and

said object to be certified being mounted non-removably a storage medium, where said first authentication verifying information is encrypted by using a first crypt key of authorities to encrypted-by-first-crypt-key first authentication verifying information and is stored, wherein, said first authentication verifying information and said encrypted-by-first-crypt-key first authentication verifying information are read;

said encrypted-by-first-crypt-key first authentication verifying information is decrypted by using the first crypt key of said authorities; and

the corresponding relation between said certificate and said object to be certified is confirmed by comparing said first authentication verifying information thus read with said decrypted first authentication verifying information as decrypted from said encrypted-by-first-crypt-key first authentication verifying information.

2. An authentication verifying system according to claim 1, wherein said certificate and said object to be certified are integrated.

3. An authentication verifying system according to claim 1, wherein said certificate and said object to be certified are separated from each other.

4. An authentication verifying system according to claim 1, wherein:

a storage medium, where said first authentication verifying information is encrypted by using a second crypt key of the authorities to encrypted-by-second-crypt-key first authentication verifying information and is stored, is further mounted non-removably on said certificate;

said encrypted-by-second-crypt-key first authentication verifying information is further read;

said encrypted-by-second-crypt-key first authentication verifying information is decrypted by the second crypt key of the authorities;

compare the first authentication verifying information of said certificate and the first authentication verifying information thus decrypted from said encrypted-by-second-crypt-key first authentication verifying information; and

the corresponding relation between said certificate and said object to be certified is confirmed.

5. An authentication verifying system according to claim 4, wherein said first crypt key and said second crypt key are the same crypt key.

6. An authentication verifying system according to claim 4, wherein said first crypt key and said second crypt key are crypt keys different from each other.

7. An authentication verifying system according to claim 1, wherein:

a storage medium, where copy-unable second authentication verifying information is stored, is further mounted non-removably on said object to be certified;

a storage medium, where said second authentication verifying information is encrypted by using a second crypt key of said authorities to encrypted-by-second-crypt-key second authentication verifying information is stored, is further mounted non-removably on said certificate;

said encrypted-by-second-crypt-key second authentication verifying information is decrypted by said second crypt key;

said encrypted-by-first-crypt-key first authentication verifying information is decrypted by using said first crypt key;

said first authentication verifying information is compared with the first authentication verifying information thus decrypted from said encrypted-by-first-crypt-key first authentication verifying information;

said second authentication verifying information is compared with the second authentication verifying information thus decrypted from said encrypted-by-second-crypt-key second authentication verifying information; and

the corresponding relation between said certificate and said object to be certified is confirmed.

8. An authentication verifying system according to claim 7, wherein said first authentication verifying information and said second authentication verifying information are the same authentication verifying information.

9. An authentication verifying system according to claim 8, wherein said first crypt key and said second crypt key are crypt keys different from each other.

10. An authentication verifying system according to claim 8, wherein said first crypt key and said second crypt key are the same crypt key.

11. An authentication verifying system according to claim 7, wherein said first authentication verifying information and said second authentication verifying information are the different authentication verifying information.

12. An authentication verifying system according to claim 11, wherein said first crypt key and said second crypt key are crypt keys different from each other.

13. An authentication verifying system according to claim 11, wherein said first crypt key and said second crypt key are the same crypt key.

14. A certificate, wherein an authentication verifying chip, which copy-unable authentication verifying information is stored therein, is non-removably mounted.

15. The certificate according to claim 14, wherein said authentication verifying chip is a part of a surface of the certificate.

16. The certificate according to claim 14, wherein said authentication verifying chip is all of a surface of the certificate.

17-23. -23. (canceled)

24. An authentication verifying information reading method, comprising the steps of:

dividing an authentication verifying information plane of an authentication verifying chip into a plurality of planes;

dividing each of said plurality of planes further to a plurality of planes;

repeating the dividing procedures;

detecting colors of a plurality of planes thus divided; and

reading the authentication verifying information plane by the colors detected.

25. A method for producing a certificate, comprising the steps of:

preparing an original plate having an area to cover a plurality of certificates;

scattering authentication verifying information carriers over the entire surface of said original plate;

cutting the original plate where said authentication verifying information carriers are scattered and obtaining a certificate base plate; and

preparing a certificate based on said certificate base plate.

26. A method for producing a certificate, comprising the steps of:

preparing an original plate having an area to cover a plurality of certificates;

scattering authentication verifying information carriers over a limited surface of said original plate;

cutting the original plate where said authentication verifying information carriers are scattered over the limited surface, and obtaining a certificate base plate; and

preparing a certificate based on said certificate base plate.

27. A method for producing a certificate, comprising the steps of:

preparing an original plate having an area to cover a plurality of certificates;

coating a thin film of authentication verifying information carriers over the entire surface of said original plate;

cutting the original plate where said authentication verifying information carriers thin film is coated, and obtaining a certificate base plate; and

preparing a certificate based on said certificate base plate.
