Access control system with multiple verification channels

Abstract

The invention provides an access control system with multiple verification channels. The access control system comprises an electronic lock, a controller, a processor, a face recognition device, a verification code verification device, a card swiping verification device and a fingerprint verification device, wherein the face recognition device takes a maximum face comparison identification rate asa first authentication coefficient S1 and transmits to the processor; the verification code verification device responds to transmit a second authentication coefficient S2 to the processor when an entered verification code is identical with a setting value; the fingerprint verification device takes a maximum fingerprint comparison identification rate as a third authentication coefficient S3 and transmits to the processor; the card swiping verification device responds to transmit a fourth authentication coefficient S4 to the processor when information of a card exists in a third storage cell;the processor calculates an overall verification coefficient S according to a formula S equal to S1 multiplied by X1 plus S2 multiplied by X2 plus S3 multiplied by X3 plus S4 multiplied by X4; and theprocessor responds to switch the electronic lock to an unlocking state when the overall verification coefficient S is greater than a set threshold. Since the multiple verification channels are adopted, under the condition that a safety level of the access control system is guaranteed, and more selection space is provided for a user.

Description

technical field [0001] The invention relates to the field of access control systems, in particular to an access control system with multiple verification channels. 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] There are also some access control systems that have introduced high-level security technologies such as fingerprint verification and iris verification. [0004] The access control system that introduces high-level solution technologies such as face recognition technology, fingerprint verificatio...

AI Technical Summary

Problems solved by technology

[0004] The access control system that introduces high-level solution technologies such as face recognition technology, fingerprint verification, and iris verification greatly reduces behaviors that are harmful to security and correct attendance, such as card swiping, but there are also some problems. For example, when the user's face For some reason, when the information such as facial area, fingerprint, iris, etc. cannot meet the recognition rate, the system will roughly consider that the user does not meet the requirements, thus rejecting the user

[0005] 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
