Abstract

Authorized persons are recognized based on unique identifiers allocated to the authorized persons and biological information of the authorized persons and a database of identifiers and biological information of authorized persons. When a person provides his identifier, biological information corresponding to the provided identifier is retrieved from the database and writing in a storage unit. Then, when the person provides his biological information, it is checked whether provided biological information matches with the biological information in the storage unit. When the two match, the person is recognized as an authorized person.

Claims

1. A biological information matching device that recognizes authorized persons based on unique identifiers allocated to the authorized persons and biological information of the authorized persons and a database of identifiers and biological information of authorized persons, the biological information matching device comprising:

a storage unit configured to store therein at least biological information;

a retrieving unit configured to retrieve from the database biological information corresponding to an identifier acquired from a person, and to write retrieved biological information in the storage unit; and

a matching unit that checks if biological information acquired from a person matches with the biological information in the storage unit to thereby decide whether the person is the authorized person.

2. The biological information matching device according to claim 1, further comprising a biological information reader configured to read biological information of persons.

3. The biological information matching device according to claim 1, further comprising an identifier reader configured to read identifiers of persons from RFID IC tags carried by the persons.

4. The biological information matching device according to claim 3, wherein the identifier reader performs reading of identifiers of persons from RFID IC tags intermittently at predetermined interval.

5. The biological information matching device according to claim 1, wherein the storage unit has a capacity substantially smaller than that of the database.

6. The biological information matching device according to claim 5, wherein the storage unit has a capacity for storing only a predetermined number of biological information.

7. The biological information matching device according to claim 4, wherein the retrieving unit deletes the oldest biological information from the storage unit when storing new biological information in the storage unit.

8. The biological information matching device according to claim 4, wherein the retrieving unit writes only most recently acquired biological information in the storage unit.

9. The biological information matching device according to claim 3, wherein the identifier reader has a variable reading power and the reading power can be adjusted to control number of RFID IC tags to be read.

10. A biological information matching method of recognizing authorized persons based on unique identifiers allocated to the authorized persons and biological information of the authorized persons and a database of identifiers and biological information of authorized persons, the method comprising:

retrieving biological information corresponding to an identifier acquired from a person from the database;

writing retrieved biological information in a storage unit; and

checking if biological information acquired from a person matches with the biological information in the storage unit to thereby decide whether the person is the authorized person.

11. The method according to claim 10, further comprising reading biological information of persons with a biological information reader.

12. The method according to claim 10, further comprising reading identifiers of persons from RFID IC tags carried by the persons with an identifier reader.

13. The method according to claim 12, wherein the reading is performed intermittently at predetermined interval.

14. The method according to claim 10, wherein the storage unit has a capacity substantially smaller than that of the database.

15. The method according to claim 14, wherein the storage unit has a capacity for storing only a predetermined number of biological information.

16. The method according to claim 13, wherein the writing includes deleting the oldest biological information from the storage unit when writing new biological information in the storage unit.

17. The method according to claim 13, wherein the writing includes writing only most recently acquired biological information in the storage unit.

18. The method according to claim 12, wherein the identifier reader has a variable reading power, and method further includes adjusting the reading power of the identifier reader to control number of RFID IC tags to be read.

19. A computer-readable recording medium that stores therein a computer program that implements on a computer a biological information matching method of recognizing authorized persons based on unique identifiers allocated to the authorized persons and biological information of the authorized persons and a database of identifiers and biological information of authorized persons, the computer program causing the computer to execute:

retrieving biological information corresponding to an identifier acquired from a person from the database;

writing retrieved biological information in a storage unit; and

checking if biological information acquired from a person matches with the biological information in the storage unit to thereby decide whether the person is the authorized person.
