Individual identification method based on multi-mode biometric information

Abstract

The application provides a method used for identifying an individual. The method comprises: determining that candidates which are in a database and have matching degrees which relate to a first biological feature and are higher than a first critical threshold value A2 are a first candidate collection; determining that the candidates which are in the first candidate collection and have matching degrees which relate to a second biological feature and are higher than a second critical threshold value B2 are a second candidate collection; and identifying the individual on the basis of the second candidate collection. According to the method, the number of matching in two matching processes is effectively reduced while the recognition accuracy is ensured, and the recognition efficiency is improved; and at the same time, the method has the characteristics of the high pass rate and the high precision which fingerprint identification has and the anti-counterfeiting ability which finger blood-vessel identification has, and effectively solves the defect of homogeneous biological information identification in the prior art.

Description

technical field [0001] The present application relates to the field of biometric identification, in particular, to a personal identification method based on multi-mode biometric information. Background technique [0002] Biometric technology and related products have been widely used in user identification and verification / authentication, such as attendance machines, smart locks in the security industry, access control machines, elevator controls, access control products for entrance and exit, parking lot products, and video surveillance products. This biometric identification method can be introduced to achieve the purposes of time management, entrance and exit security control, and people flow statistics. Biometric technology can also be integrated and applied to large-scale software and projects. Specifically, these products can be applied to any environment that requires access control and security control, such as banks, enterprises, institutions, prisons, families, sch...

AI Technical Summary

Problems solved by technology

In this identification mode, each identification needs to match the biometric data of the individual to be identified with all the data in the corresponding database. When the number of users to be identified in the same database is large, this combined identification mode The time spent on a single verification is greatly increased
