Access control method and multi-access host anti-back system

Abstract

The embodiment of the invention provides an access control method and a multi-access host anti-back system, relates to the field of security and protection, and can reduce the delay of obtaining a verification result of target verification information by access hosts. The method is applied to a target access control host in the multi-access host anti-back system, and comprises the following steps that before receiving target verification information of a first user from a target gate, the target access control host receives anti-pass-back information of the first user from an access control service host in the multi-access control host anti-back system; the anti-pass-back information is used for indicating a gate passing rule of the first user; the target access control host receives target verification information from the target gate; the target access control host verifies the target verification information according to the anti-pass-back information, and controls the operation state of the target gate according to the verification result; and the operation state comprises an opening state or a closing state.

Description

technical field [0001] The invention relates to the security field, in particular to an access control method and an anti-passback system for multiple access control hosts. Background technique [0002] In current multi-access control host anti-passback systems, an access control host is usually designated as the access control service host, and the anti-passback information (anti-passback rules corresponding to all legal personnel) of all personnel is stored in the access control service host. Other access control hosts need to transmit the target verification information received by themselves (that is, the information provided by the user to identify themselves by swiping cards or fingerprint touches) to the access control service host for verification and obtain the corresponding verification results. The result of the verification determines whether the gate is instructed to open. However, if the communication network delay between an access control host and the access...

AI Technical Summary

Problems solved by technology

However, if the communication network delay between an access control host and the access control service host is high, or if there are many target verification information sent to the access control server host for verification, the delay in obtaining the verification result for the access control host will be high, and the user experience will be poor. good
