In a specific embodiment, the access control method may include the steps of:
step S01: information entry
Before the access control system is used for controlling the access control, target personnel information is input into equipment. Through an access control management platform, an authorizer inputs biological characteristics, inputs an authentication password and makes an authorization card; the user inputs the biological characteristics, inputs the access code and makes an access card. The peripheral machine is temporarily connected to the access control management platform through wired connection modes such as USB interface connection and the like, and can carry out operations such as downloading related identity information, uploading working records, updating records of identity information and the like; the gate machine has the basic functions of a biological characteristic recognition device (or a gate recognition device based on other recognition principles), can access a gate management control platform, and receives platform management and control.
Step S02: application authorization
When a user has a requirement for opening the access control, an access control opening application is provided for an authorizer according to a management system flow.
After the application is passed, the authorizer uses the peripheral machine to perform biological characteristic authentication, authorized password authentication and authorized card authentication, and the peripheral machine enters an authentication password generation link after all three kinds of authentication are passed.
The authorized person selects the user, needs to open the door, and clicks to generate the authentication password after the validity period of the authentication password. The peripheral machine adds the random number generated at this time according to the information such as the serial number of the peripheral machine, the serial number of the machine needing to open the door, the information of an authorizer, the information of a user, the authorization time, the validity period of the authentication password and the like, encrypts the information by using a mature encryption algorithm such as an RSA algorithm and the like, and generates the authentication password. Since the above information changes every time a password is generated, the authentication password generated every time is different.
The authorizer delivers the authentication code offline to the user. The user can carry out the entrance guard opening work after obtaining the authentication password.
Step S03: information authentication
The user uses the door computer to carry out biological characteristic authentication, access control password authentication and access control card authentication, and all three kinds of authentication enter an authentication password input link through the rear door computer.
The user inputs the authentication password into the door machine, and the door machine obtains the number of the external machine, the number of the door machine needing to be opened, the information of the authorizer, the information of the user, the authorization time, the validity period of the authentication password and the like through a decryption algorithm. The door machine checks the information: if the opening time is within the validity period of the authentication password, the authentication password is not repeated, the serial number of the external machine is correct, the serial number of the door to be opened is matched, the information of the authorized person is correct, and the information of the user is correct, the authentication is passed, the door is operated by the door to control the opening of the electric control lock, and the user can open the door control. Otherwise, if any condition is not met, the authentication fails, and the entrance guard is not opened.
In order to ensure that the user can not open the access control at will after obtaining the authentication password, the door operator compares the authentication password with the working record after inputting the authentication password, and if the authentication password is found to be repeated, the access control opening authentication fails.

s14: the peripheral machine generates an authentication password according to a preset encryption algorithm;
s15: the user obtains the authentication password.
In this embodiment, the preset encryption algorithm may be an RSA encryption algorithm, and the peripheral device may generate the authentication password only after the biometric features, the authorization password, and the authorization card in the authorization authentication pass the authentication, where the biometric features refer to the inherent physiological features of the human body, and may include a face, a fingerprint, and an iris, etc.
Step S2: and (5) information authentication.
Specifically, as shown in fig. 4, step S2 includes:
s21: the user inputs the biological characteristics, the access code and the access card into the door computer to carry out user authentication;
s22: when the user passes the authentication, the user inputs an authentication password to the door computer;
s23: the gate computer analyzes and obtains the information of the authorized person, the information of the user, the vault gate number and the validity period of the authentication password according to the authentication password;
s24: judging whether the authentication password is recorded, if so, not opening the access control, otherwise, executing the step S25;
s25: judging whether the authentication password exceeds the valid period, if so, not opening the access control, otherwise, executing the step S26;
s26: judging whether the vault door number and the information of the authorizer are wrong, if so, not opening the access control, otherwise, executing the step S27;
s27: and judging whether the user information is wrong or not, if so, not opening the access control, and otherwise, opening the access control.
