An intelligent access control system based on fingerprint and finger vein joint recognition

Abstract

The present invention provides an intelligent access control system based on joint identification of fingerprints and finger veins. The access control system includes: a power supply management circuit; Image algorithm processing of data and information processing control part for authenticating fingerprint images and finger vein images; the power management circuit is electrically connected with the image acquisition device, information processing control part and electric control lock respectively, and the image acquisition device and electronic The control locks are respectively connected with the signal of the information processing control part. The intelligent access control system guarantees the accuracy and uniqueness of the access control system authentication through dual-mode biometric authentication combining fingerprint recognition technology and finger vein recognition technology, thereby improving the security, reliability and anti-counterfeiting of the access control system. At the same time, the access control system of the present invention has multiple functions, so as to realize the intelligence of the access control system and improve the experience of users.

Description

technical field [0001] The invention relates to the technical field of security verification, and more specifically, relates to an intelligent access control system based on joint identification of fingerprints and finger veins. Background technique [0002] With the development of science and technology, people's life is gradually becoming intelligent. As the core equipment of home security, the intelligent access control system aims to authenticate the user's identity and prevent malicious intrusion. Traditional access control systems such as smart card systems and password systems can only identify the card or password itself, but cannot directly identify the user, and the authentication information is easily stolen or copied. Biometric technology can identify users through the characteristics of the human body itself, such as veins on the back of the hand, palms, eyes, fingerprints or voice, so biometric technology is gradually applied to modern access control systems. ...

AI Technical Summary

Problems solved by technology

[0003] Although there are more and more authentication systems based on biometric technology, they all use a single biometric feature, such as a single pair of fingerprints for verification, etc.

Each single biometric feature has its disadvantages making the system less secure and reliable

For example, fingerprints are easy to forge and are sensitive to surface cleanliness; iris recognition lacks comfort, etc.

Moreover, existing access control systems on the market have shortcomings such as single function, poor affinity, and poor user experience. Research
