Description

A 4G communication-based access control system and its access authorization method

technical field

The invention relates to the field of security protection, in particular to a 4G communication-based access control system and an access authorization method thereof.

Background technique

Existing access control systems usually collect card information, password information or fingerprint information by swiping electronic cards, entering passwords or collecting fingerprints to confirm the legal identity of the user, and at the same time judge the request by comparing the information in the database with the access control controller. is it legal. However, there are still great risks. For example, electronic cards are easy to imitate, and once the cardholder loses the electronic card, he will not be able to enter the access control. At the same time, if the electronic card is picked up by criminals, it will bring hidden dangers to the access control; It seems that the method that can greatly improve the security performance of access control also has many problems in actual operation, such as irregular movements when collecting fingerprints, foreign objects on the finger surface, sensor aging and external temperature environment changes, etc., which will lead to identity verification. s failure. The more prominent hidden dangers of the current access control system include that when other users who do not have authorization information need to enter, and the legitimate user is not in the house and cannot open the door for the visitor, the visitor can only be turned away or follow other legitimate users to enter , which brings great inconvenience to users.
