Intelligent community system and method based on fingerprint and finger-vein recognition

Abstract

The invention discloses an intelligent community system and method based on fingerprint and finger-vein recognition. The intelligent community system comprises a fingerprint recognition unit, a face recognition unit, a finger-vein recognition unit, an authentication server, a linkage controller and a front end linkage device. The method comprises the steps that when an authentication result is illegal, an expression recognition module and a photoelectric pulse sensor driving module are started, and a risk judgment module judges a total risk value of the illegal target according to expression and pulse information of the object to be tested; the linkage controller outputs a control signal to the front end linkage device according to total risk value data and preset control logic. According to the intelligent community system and method based on the fingerprint and finger-vein recognition, fingerprint recognition, face image recognition and finger-vein lines image identification are effectively combined, when legality identification is conducted, it is required that fingerprint comparison, face image comparison and finger-vein lines comparison results all display that the object to be tested is the legal user, and the fingerprints, a face image and finger-vein lines belong to the same legal user, and the accuracy and reliability of community safe-protection management are effectively improved.

Description

technical field [0001] The invention relates to a smart community system, in particular to a smart community system and method based on fingerprint and finger vein recognition. Background technique [0002] As the public has higher and higher requirements for public access security, the use of smart community access control systems is becoming more and more popular. At present, the common access control systems on the market usually use radio frequency card authentication. As long as there is an access control card, it can pass the authentication. Illegal users may obtain legal access control cards through theft and other methods, and there are great loopholes in the management method. In addition, for legal users, access control cards must be carried in and out of the door, and the access control cards are easily lost or damaged, which brings great inconvenience to legal users. [0003] In recent years, in order to provide greater convenience for users, many access control...

AI Technical Summary

Problems solved by technology

However, the single fingerprint authentication method has the following problems: (1) The recognition rate is low. If the user's fingers appear peeling, blistering, etc., it is difficult to identify them correctly; (2) There are many fingerprint sets on the market. The reliability of fingerprint authentication is gradually reduced

[0004] In addition, the existing access control systems only provide authentication functions, and cannot provide effective linkage measures when illegal users are found
