Access control system based on human face recognition technique

Abstract

The invention provides an access control system based on a human face recognition technique. The access control system comprises an electronic door lock, a first controller, a processor, a human facerecognition device, a second controller, a card swiping verifying device, wherein the processor is used for making comparison on received user face information with a human face information database in corresponding to the received user face information sent by the human face recognition device, (1) driving a first controller to switch the electronic door lock into an unlocked state in corresponding to the situation that the highest comparison recognition rate is higher than a first set threshold, and (2) driving a second controller to unlock a power lock of the card swiping verifying device in corresponding to the situation that highest comparison recognition rate is higher than a second set threshold and lower than the first set threshold to drive the card swiping verifying device to normally work so as to realize further identity authentication. According to the access control system, two verifying channels are set, and one verifying channel is started only meeting a specific condition, so that users can still rapidly pass through a door, and the security level of the access control system is not decreased.

Description

technical field [0001] The invention relates to the field of access control systems, in particular to an access control system based on face recognition technology. Background technique [0002] The access control system is the key to security, and in some occasions, the key to attendance. With the development of technology, face recognition technology has gradually been applied to the access control system. After the user has recorded the face information, when he approaches the access control system, the face recognition device can capture the user's face information for identification. When the set recognition rate is met, the access control is opened for users to pass. [0003] Although the access control system that introduces face recognition technology greatly reduces the behaviors that are harmful to security and correct attendance, such as swiping cards on behalf of others, there are still some problems. For example, when the user's face cannot meet the recognition...

AI Technical Summary

Problems solved by technology

[0003] Although the access control system that introduces face recognition technology greatly reduces the behaviors that are harmful to security and correct attendance, such as swiping cards on behalf of others, there are still some problems. For example, when the user's face cannot meet the recognition rate for some reasons, The system will rudely consider that the user does not meet the requirements, thus rejecting the user

[0004] In order to avoid this problem, in some occasions, people have to avoid the problem by reducing the set recognition rate. On the one hand, this can only avoid part of the problem. On the other hand, it also reduces the security and attendance. accuracy
