Abstract

There are provided a living body collating device, a living body collating system and a living body collating method, which is equipped with optimization candidate data extracting means 35 for extracting optimization candidate data for data renewal from past record data of living body information achieved, optimization candidate data storage means 36 for storing the optimization candidate data extracted by the optimization candidate data extracting means 35, and renewal storage means 37 for storing, as new registration data, the data having higher priorities of the optimization candidate data stored in the optimization candidate data storage means 36 and registration data stored in registration data storage means.

Claims

1. A living body collating device including living body information achieving means for achieving living body information, registration data storage means for storing registration data, and collating means for collating the living body information thus achieved with the registration data, characterized by further including:

optimization candidate data extracting means for extracting optimization candidate data for data renewal from the achieved living information when the living body information is collated;

optimization candidate data storage means for storing optimization candidate data extracted by the optimization candidate data extracted by said optimization candidate data extracting means; and

renewal storage means for newly storing data having high priority as new registration data from the optimization candidate data stored in said optimization candidate data storage means and the registration data stored in said registration data storage means, thereby renewing the registration data.

4. The living body collating device as claimed in any one of claims 1, 2 and 3, further including error rate calculating means for calculating an error rate of collation data, and registration data renewal target person extracting means for extracting registration data necessary to be renewed on the basis of the error rate calculated by said error rate calculating means.

5. The living body collating device as claimed in claim 4, wherein said error rate calculating means has a first threshold value used for collation and a second threshold value set to be lower than the first threshold value, and an error whose error rate is not more than the second threshold value is not used for calculation of the error rate.

6. The living body collating device as claimed in claim 1, 2 or 3, wherein the registration data has attribute information, and the renewal by said renewal storage means is carried out by using the attribute information.

7. The living body collating device as claimed in claim 6, wherein the attribute information contains one or both of date data and using frequency for collation.

8. The living body collating device as claimed in claim 6 or 7, wherein the attribute information contains the presence or absence of glasses.

9. The living body collating device as claimed in claim 1, 2 or 3, wherein the registration data has a predetermined number of image data, and said renewal storage means renews a prescribed number of image data from the predetermined number of image data.

10. The living body collating device as claimed in claim 1, 2 or 3, wherein said optimization candidate data extracting means extracts the optimization candidate data every time collation is carried out.

11. The living body collating device as claimed in claim 1, 2 or 3, wherein said optimization candidate data extracting means extracts image data having low collation reliability degree.

12. The living body collating device as claimed in claim 1, 2 or 3, wherein said optimization candidate data extracting means also extracts image data whose collation fails.

2. A living body collating device including living body information achieving means for achieving living body information, registration data storage means for storing registration data and collating means for collating the living information thus achieved with the registration data, characterized by further including registration data renewal target person output means for outputting registration data to be renewed in accordance with the frequency of collation failure of said collating means.

3. A living body collating device including living body information achieving means for achieving living body information, registration data storage means for storing registration data and collating means for collating the living information thus achieved with the registration data, characterized by further including:

registration candidate data storage means for storing registration candidate unused for collation; and

renewal storage means for renewing registration data stored in said registration candidate data storage means with the registration candidate data.

13. A living body collating system, characterized by including a center device that is equipped with optimization candidate data storage means for storing optimization candidate data extracted by said optimization candidate data extracting means, and renewal storage means for storing, as new registration data, the data having higher priorities of the optimization candidate data stored in said optimization candidate data storage means and the registration data stored in said registration storage means.

14. A living body collating method of achieving an image of living body information and collating the image thus achieved with registration data stored in advance in storage means, characterized by comprising the steps of:

extracting optimization candidate data for data renewal from past record data of the living body information thus achieved; and

renewing the registration data by selecting data having higher priorities from the optimization candidate data extracted and the registration data.

15. A registration data renewing method for a living body collating device and a living body collating system, characterized by comprising:

a step of extracting registration candidate data from a past record;

a step of storing the registration candidate data thus extracted; and

a step of renewing registration data for collation by using the registration candidate data.
