Description

Smart door security control method and system

technical field

The invention belongs to the technical field of network information system security, and in particular relates to an intelligent door security control method and system.

Background technique

At present, access control cards or keys are usually used for security control of buildings, private places in communities, and corporate offices. Visitors often have to go to designated office areas to process access control cards, and obtain access rights after going through cumbersome procedures. Self-management, while security management relies on the responsibility of guards, high management costs and human-made single point of responsibility risks in security control.

To solve the above problems, there are authentication access control schemes based on symmetric public key system and authentication access control scheme based on asymmetric key system, but these schemes have loopholes in reuse of authentication licenses, high cost of centralized management, and poor quality of security services.

Contents of the invention

Aiming at the problem of public access security control, the present invention provides a smart door security control method and system. The method and system are based on the master-slave key of the smart phone and the time-sensitive variable authentication access scheme, and realize the integration of centralized access management and distributed access management. , reduce security risks, and improve security service quality.

In order to achieve the above object, the present invention adopts the following technical solutions:

The smart door security control method is driven by the access key information negotiated by the receptionist and the visitor through the smart phone, and the intelligent switch controller generates the closing or opening control command of the physical door according to the correctness of the received access key ; The access key information includes one or more of Chinese character strings, numeric strings, English character strings, mixed character strings, pictures, faces and mobile phone numbers; the method includes the following steps:

1) Master key generation and distribution method

The security management center requires the owner of the smart door to issue a real door identity certificate to obtain the master key. The master key is in one or more of the following forms: the smart phone number of the authorizer, the hardware serial number of the smart device of the authorizer, the authorized The character string set by the person, the public key of the authorizer and the biometric information of the authorizer;

2) Associated key generation and distribution method

The recipient who has the master key automatically generates the associated key through the smart phone APP program, the process is:

① The visitor chooses the information as the access key and sends it to the host;

②The receptionist uses the Hash algorithm to generate digital fingerprints from the information;

③ The receptionist uploads the digital fingerprint to the public smart door management center;

3) Visitor access control process, visitor access control steps are described as follows:

①The visitor sends an access key request to the host;

② The host generates an associated access key;

③Send the associated access key to the security management center;

④ The smart door security management center dynamically updates the access key database, and establishes the relationship between the associated key and the master key;

⑤ The server of the smart door security management center checks whether the associated key of the visitor is correct, and if it is not expired and correct, it will issue a control command and open the physical door; otherwise, it will display a rejection message.

Smart door security control system, which is driven by the access key information negotiated by the receptionist and the visitor through the smart phone, and the intelligent switch controller generates the closing or opening control command of the physical door according to the correctness of the received access key ; The access key information includes one or more of Chinese character strings, digital strings, English character strings, mixed character strings, pictures, faces and mobile phone numbers; the control method of the system includes the following steps:

1) Master key generation and distribution method

The security management center requires the owner of the smart door to issue a real door identity certificate to obtain the master key. The master key is in one or more of the following forms: the smart phone number of the authorizer, the hardware serial number of the smart device of the authorizer, the authorized The character string set by the person, the public key of the authorizer and the biometric information of the authorizer;

2) Associated key generation and distribution method

The recipient who has the master key automatically generates the associated key through the smart phone APP program, the process is:

① The visitor chooses the information as the access key and sends it to the host;

②The receptionist uses the Hash algorithm to generate digital fingerprints from the information;

③ The receptionist uploads the digital fingerprint to the public smart door management center;

3) Visitor access control process, visitor access control steps are described as follows:

①The visitor sends an access key request to the host;

② The host generates an associated access key;

③Send the associated access key to the security management center;

④ The smart door security management center dynamically updates the access key database, and establishes the relationship between the associated key and the master key;

⑤ The server of the smart door security management center checks whether the associated key of the visitor is correct, and if it is not expired and correct, it will issue a control command and open the physical door; otherwise, it will display a rejection message.

Due to the adoption of the above technical solution, the present invention has the following characteristics: 1. Distributed management of visitors reduces the waiting time of visitors and enhances user service experience. 2. Dynamically generate access keys, which are time-sensitive and avoid repeated use. 3. Avoid the single-point risk of public door safety responsibility and enhance the controllability of public door safety.

Description of drawings

Figure 1 is a diagram of the working mechanism of the intelligent public door.

detailed description

The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

1. Intelligent public door safety control method

The safe opening of the intelligent public door is driven by specific information negotiated by the receptionist and the visitor through the smart phone. The specific information is called the access key, and the intelligent switch controller generates the physical door according to the correctness of the received access key. The close or open control command. The driver information of this method includes the following:

Chinese character string

numeric string

English string

mixed string

picture

human face

mobile phone number.

2. Master key generation and distribution method

The security management center requires the owner of the smart door to issue a real door identity certificate to obtain the master key. The form of the master key is:

Authorizer's smartphone number

Authorizer's smart device hardware serial number

Authorizer's self-defined string

Authorizer's public key

Authorizer's biometric information.

3. Associated key generation and distribution method

The receiver who masters the master key automatically generates the associated key through the smart APP program, as shown in Figure 1, and the process is:

The visitor chooses the information as the access key and sends it to the receptionist (the subject of the physical access area).

The host uses the Hash algorithm to generate digital fingerprints from the information.

The receptionist uploads the digital fingerprint to the public smart door management center.

4. Visitor access control process

The visitor access control steps are described as follows:

The visitor issues an access key request to the host.

The host generates an associated access key.

Send the associated access key to Security Manager.

The smart door security management center dynamically updates the access key database, and establishes the relationship between the associated key and the master key.

The server of the smart door security management center checks whether the associated key of the visitor is correct, and if it has not expired and is correct, it will generate a control command to open the physical door. Otherwise, a rejection message is displayed.
