Intelligent entrance guard system based on fingerprint and finger vein joint recognition

Abstract

The invention provides an intelligent entrance guard system based on fingerprint and finger vein joint recognition. The entrance guard system comprises a power supply management circuit, an electric control lock, an image collection device and an information processing control section, wherein the information processing control section is used for obtaining data and information of images collected in the image collection device, carrying out image algorithm processing on the data of the images and carrying out authentication on a fingerprint image and a finger vein image; the power supply management circuit is electrically connected with the image collection device, the information processing control section and the electric control lock respectively; and the image collection device and the electric control lock are respectively connected with the information processing control section via a signal. According to the intelligent entrance guard system, the accuracy rate and the uniqueness of entrance guard system authentication are ensured by bimodal biological characteristics authentication combining a fingerprint identification technology and a finger vein identification technology, thereby improving the safety, the reliability and the anti-counterfeit property of the entrance guard system, and meanwhile, the entrance guard system disclosed by the invention has multifunctionality, thereby achieving intelligentization of the entrance guard system and improving the user experience.

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
