Abstract

A certification information generating apparatus includes: a feature quantity generator, for generating a feature quantity related to a paper medium on which identification information is printed; and a database generator, for generating a database wherein the feature quantity and the identification information are correlated with each other. The database that is generated is employed for a predetermined process related to certification of a paper medium.

Claims

1. A certification information generating apparatus comprising:

a feature quantity generator that generates a feature quantity related to a paper medium on which identification information is printed; and

a database generator that generates a database in which the feature quantity and the identification information are correlated with each other,

wherein the database that is generated is employed for a predetermined process related to certification of a paper medium.

2. The certification information generating apparatus according to claim 1,

wherein said feature quantity related to said paper medium is a feature quantity correlated with a pattern of a paper fiber for at least one predetermined area on said paper medium.

3. The certification information generating apparatus according to claim 2,

wherein said predetermined area includes at least one of an area near a corner of said paper medium and an area at an end of said paper medium.

4. A certification apparatus comprising:

an acquisition unit that obtains identification information printed on a paper medium to be certificated;

a feature quantity acquisition unit that obtains from a database in which a feature quantity and the obtained identification information are correlated with each other, information for the feature quantity that is correlated with the identification information;

a feature quantity generator that generates a feature quantity related to the paper medium to be certificated,

wherein the obtained information for the feature quantity and the information for the generated feature quantity are employed for a predetermined processsing related to certification.

5. A certification information generation method, comprising the steps of:

generating a feature quantity related to a paper medium on which identification information is printed; and

generating a database in which the feature quantity and the identification information are correlated with each other,

wherein the generated database is employed for a predetermined processing related to certification of the paper medium.

6. A method for controlling a certification apparatus that employs a database, generated by a certification information generation apparatus, that includes a feature quantity generator for generating a feature quantity related to a paper medium on which identification information is printed, and a database generator for generating a database in which the feature quantity and the identification information are correlated with each other, the method enabling the certification apparatus to perform the steps of:

obtaining identification information printed on a paper medium to be certificated;

obtaining, from the database, information for the feature quantity that is correlated with the obtained identification information; and

generating a feature quantity related to the paper medium to be certificated,

wherein the information obtained for the feature quantity and the information for the feature quantity that is generated are employed for a predetermined processing related to certification.

7. A program product that enables a computer to generate certification information comprising:

software instructions for enabling the computer to perform predetermined operations; and

a computer-readable recording medium bearing the software instructions,

wherein the software instructions include the steps of

generating a feature quantity related to a paper medium on which identification information is printed, and

generating a database wherein the feature quantity and the identification information are correlated with each other; and

the generated database is employed for a predetermined processing related to certification of the paper medium.

8. A program product, which enables a certification apparatus including a computer to employ a database generated by a certification information generation apparatus that includes a feature quantity generator, for generating a feature quantity related to a paper medium on which identification information is printed, and a database generator, for generating a database in which the feature quantity and the identification information are correlated with each other, comprising:

a software instructions for enabling the computer to perform predetermined operations; and

a computer-readable recording medium bearing the software instructions,

wherein the software instructions enables the computer to perform the steps of

obtaining identification information printed on a paper medium to be certificated,

obtaining, from the database, information for the feature quantity that is correlated with the obtained identification information, and

generating a feature quantity related to the paper medium to be certificated, and

wherein the obtained information for the feature quantity and the generated, information for the feature quantity are employed for a predetermined processing related to certification.
