A Finger Multimodal Feature Synchronous Acquisition System

Abstract

A system for synchronous collection of multimodal features of a finger, comprising a finger skin fingerprint collection module (1000), a finger OCT information collection module (1100), a support module (1200), a finger OAG information processing module (1300) and a computer (1400); The support module (1200) is used to expand the data interface so that the data transmission and power output between the computer and each module; the finger skin fingerprint collection module (1000) is used to realize the collection of finger skin fingerprint information; the finger OCT information collection module (1100) is used for Yu is responsible for the collection of finger OCT information; the finger OAG information processing module (1300) is used to convert OCT information into OAG information; the computer (1400) is used to further process the collected information. The invention can obtain finger skin fingerprints, finger dermis fingerprints and sweat glands, and finger subcutaneous blood flow velocity information.

Description

Technical field[0001]The present invention belongs to the field of biomechanical identification, especially a system of synchronous acquisition finger leather fingerprint, finger leather fingerprint and sweat gland, finger skin flow rate information.Background technique[0002]The rapid development of information technology has made the whole society a combination of information and networks. Social informationization and network safety have become an important topic. The traditional identity authentication method is easily forged or posing, and biometric technology is to authenticate the individual's own characteristics, and the security is greatly strengthened. However, since a single modal finger biometric feature will receive a number of problems in practical applications, such as the influence of data noise, and with the progress of biometric fake technology, anti-counterfeiting is more likely to be challenged.[0003]Therefore, multiple modal biometrics are integrated to accomplis...

AI Technical Summary

Problems solved by technology

Traditional identity authentication methods are easy to be forged or impersonated, and biometric technology is to authenticate and identify the unique characteristics of individuals, greatly enhancing security

However, due to the limitations of single-modal finger biometrics in practical applications, such as being susceptible to data noise, and with the advancement of biometric forgery technology, anti-counterfeiting is more likely to be challenged.
