Problems solved by technology

[0004] On the other hand, in the case of selecting the collation order in a plurality of registered data in a random manner, even if one person is a registered person, the number of collations may be relatively large
That is, in the case where one person is a registered person, the processing efficiency is unstable

Embodiment Construction

[0029] (1) Check method

[0030] A collation method using registration data is described with reference to FIGS. 1 and 2 in which a plurality of registration data is assumed to be stored in a storage medium. In this collating method, in step SP1, before starting collating, for a plurality of registration data, a degree of similarity between these data (hereinafter referred to as a first degree of similarity) is obtained.

[0031] In FIG. 1, "T" represents registration data, and appended numerals "1 to n" represent registration numbers, and appended numerals "X1, X2" represent intermediate registration numbers. In addition, the corresponding numerical values ​​in FIG. 1 represent the first degree of similarity, in which a case of perfect agreement is set to "1". In FIG. 1 , for convenience, the first similarities are arranged in the matrix direction according to the registration order.

[0032] In the state where the first degree of similarity has been obtained, if data (here...

Abstract

The invention provides a checking method, a registration device and a checking device. In this method, for a plurality of registered data stored in a storage medium, a first degree of similarity between the data is calculated before starting collation, and among the plurality of registered data, one registered data selected as a collation object and the required degree of similarity are calculated. A second degree of similarity between reference data checked against this one registration data, and if the second degree of similarity is not such that a person can be recognized as a registered person, in other registration data other than this one registration data , excluding the registration data that has been checked as the checking object in the past, in the first similarity between this registration data and other registration data, select the registration data whose similarity is closest to the second similarity as the next checking object .

Description

technical field [0001] The present invention relates to a collation method, a registration device, a collation device and a program expected to be applied to biometrics authentication. Background technique [0002] A device is employed in which biological patterns of a plurality of persons satisfying predetermined conditions are stored as registered data, and when one registered data selected from the plurality of registered data thus stored is combined with When the check result (cross-correlation value) between the reference data for which the registration data is checked is equal to or greater than a threshold value, the person is recognized as a registrant, wherein a person who satisfies a predetermined condition is, for example, allowed to enter a predetermined place person or a person who is permitted to use a predetermined personal computer. [0003] In general, such a piece of registration data is continuously selected in a random manner until the collation result (...
