Document Type and Number:
WIPO Patent Application WO/2022/070349
Kind Code:
A1
Abstract:
Provided is a threshold value calculation system (10) comprising: a first acquisition means (110) for acquiring collation information to be used for collation of a biological body; a second acquisition means (120) for acquiring attribute information indicating the attribute of the biological body; a storage means (130) for storing the collation information and the attribute information for each biological body; a sample extraction means (140) for extracting a plurality of pieces of collation information from the storage means as sample data on the basis of a predetermined condition on the attribute information; a population estimation means (150) for estimating a population from the sample data; and a threshold value calculation means (160) for calculating a threshold value relating to the collation information on the basis of the distribution of the estimated population. According to the threshold value calculation system, it is possible to appropriately calculate a threshold value relating to biometric authentication.
