Description

How to generate password for access control system

technical field

The invention relates to an intercom system, in particular to a method for generating a code for an access control system.

Background technique

At present, the building access control system of many communities is no longer just an indoor station (set in the room of the user's residence) and a unit door station (set at the entrance of the unit of the building where it is located), but also adds a community door station (set at the entrance of the community) place), the indoor station can be connected with the unit outdoor station and the community outdoor station through Ethernet, and its password information is recorded on a server (usually arranged in the property management center) connected with the Ethernet. The network may include a switch to facilitate information transfer.

Wherein, the indoor unit of the building access control system may be an intelligent terminal with a user interaction interface or a video intercom indoor unit. The intelligent terminal can receive the audio and video data transmitted from the unit outdoor station or community outdoor station, display the video data on the display screen and play the audio data on the speaker.

When the user enters the door of the community or unit, he can unlock the door of the community or unit by inputting the password to open the door on the community VTO or unit VTO.

At present, the door opening password is usually set by the property company on the server and changed regularly, and the property company is responsible for sending the new password to the user's mailbox or mobile phone to inform the user.

There are some defects in the setting method of the above-mentioned door opening password. 1. It is easy to leak the secret: many users share a password and easily cause the leak of the password, which brings hidden dangers to the personal and property safety of the user; 2. The password is not easy to remember: the password set by the property company It is very unfamiliar to the user, and the user easily forgets the password, causing the user to be unable to open the unit door, and the user has to remember the different passwords that are changed regularly, which adds difficulties to the user; 3. Management trouble: if there is an unexpected situation, If the user does not receive the changed password, the user cannot open the unit door, which brings trouble and inconvenience to the user.

In order to solve the above problems, the user can go to the property company or request to modify his password, so that each user can set his own password for opening the door.

The defect of the setting method of this door-opening password is: since all users need to go to the property company to change the password, cause the problem of inconvenient modification of the password, and generate the same problem for the community door station and the unit door station password.

Contents of the invention

In view of this, the main purpose of the present invention is to provide a method for generating a password in an access control system, which can modify the password through the indoor unit and generate passwords for different unit VTOs and cell VTOs.

The generation method of the access control system password provided by the invention comprises:

A. Receive the user password set by the user through the indoor unit;

B. Generate a unit VTO password and a community VTO password according to the user password, the community ID, building ID, unit ID, and indoor unit ID corresponding to the indoor unit.

From the above, it is possible to set the user password through the indoor station, and generate different passwords for the unit outdoor station and community outdoor station. Prevent users from going to the server to change the corresponding password.

Wherein, before step A, a step of authenticating the user is also included.

From the above, the security of user password input can be realized.

It also includes: a step of judging whether the input new user password is a valid password.

From the above, the security of the generated password can be further improved because the number that is too simple in the password is used as an effective password.

Wherein, the cell ID, building ID, unit ID and indoor unit ID are provided by the indoor unit.

From the above, the server does not need to record the above information, which simplifies the amount of data maintenance.

Wherein, the cell ID, building ID, unit ID and indoor unit ID are stored in advance corresponding to the IP address of the indoor unit;

The cell ID, building ID, unit ID and indoor unit ID in step B are determined according to the IP address of the indoor unit.

From the above, through the above method, the amount of information transmitted during information transmission can be reduced, and the speed of information transmission and information processing can be accelerated.

Wherein, the step of generating unit door phone password and cell door phone password includes:

Select the ID needed to generate community door machine passwords and unit door secrets from the community ID, building ID, unit ID and indoor unit ID;

According to the order of user password, indoor station ID, unit ID, building ID and community ID, the user password and the selected ID characters required to generate the community outdoor station password and unit outdoor station password are superimposed to generate the community outdoor station password and Unit door phone password.

The password generated by the above can quickly judge whether the input is wrong during use, which simplifies the data processing capacity of the outdoor station of the community or the outdoor station of the unit, and also greatly shortens the time, preventing the user from entering a long string of passwords. After the number, an error will be prompted.

Wherein, selecting the ID for generating the password of the outdoor station in the community is the user password, unit ID, and building ID; selecting the ID for generating the password for the unit outdoor station is the user password and the unit ID;

The community VTO password generated by superposition of characters is: user password + unit ID + building ID;

The unit VTO password generated by character superimposition is: user password + unit ID.

Wherein, selecting the ID for generating the password of the outdoor station in the community is the user password, unit ID, building ID, and community ID; selecting the ID for generating the password for the outdoor station of the unit is the user password, unit ID, and building ID;

The community VTO password generated by character superposition is: user password + unit ID + building ID + community ID;

The unit VTO password generated by superposition of characters is: user password + unit ID + building ID.

From the above, for the two implementations provided by the present invention, password generation methods with different lengths can be selected according to security requirements and processing speed.

Wherein, select the ID that generates the password of the door station of the community as the unit ID and building ID; select the ID that generates the password of the unit door station as the unit ID;

The community VTO password generated by superposition of characters is: building ID+unit ID+user password;

The unit VTO password generated by character superimposition is: unit ID+user password.

Wherein, the ID for generating the cell door phone password is selected as the unit ID, building ID, and community ID; the ID for generating the unit door phone password is selected as the unit ID and building ID;

The community VTO password generated by character superposition is: community ID + building ID + unit ID + user password;

The unit VTO password generated by superposition of characters is: building ID+unit ID+user password.

From the above, for the other two implementations provided by the present invention, password generation methods with different lengths can be selected according to security requirements and processing speed.

Wherein, after step B, it also includes: sending the generated cell door phone password to the corresponding cell door phone according to the cell ID; sending the generated unit door phone password to the corresponding cell ID, building ID and unit ID. unit outdoor station.

From the above, the corresponding password is sent to the specific community outdoor station and unit outdoor station. During use, there is no need to exchange information with the server, which greatly shortens the data processing time, such as the time for judging the corresponding password.

Detailed ways

Fig. 1 is a structural diagram of a building access control system. As shown in the figure, each indoor station 100, unit outdoor station 200, community outdoor station 300 and server 400 in the building are connected to each other through an Ethernet switch to form a local area network.

In the present invention, the user submits information for generating a password through the indoor station 100, and the information is transmitted to the server 400, and the server 400 generates different passwords for the unit outdoor station 200 and the community outdoor station 300 according to the information and sends them to the unit outdoor station 200 and community door station 300 for storage.

Referring to the flow chart shown in Figure 2 below, the password generation method of the present invention is described in detail, including the following steps:

Step 201, the indoor unit 100 receives the authentication password input by the user on its interactive interface and performs authentication on it, and allows the user to log in and enter the interface for setting the user password after passing the authentication.

Step 202, the indoor unit 100 receives the new user password input by the user on the interface for setting the user password.

Step 203, the indoor unit 100 determines whether the new user password input by the user is a valid password, and when it is determined that the input user password is an invalid password, it prompts the user password to be invalid and prompts to re-enter another password through the interactive interface, and returns to step 202; , proceed to the next step.

This step is to prevent the user from setting a very simple user password. You can pre-set some commonly used numbers, such as 123456, 111111, 888888, etc. as invalid passwords, which are not allowed to be used as user passwords to increase the security of user passwords.

Step 204, the indoor unit 100 encrypts the input new user password using an encryption algorithm, such as the MD5 algorithm, and then sends it to the server 400; wherein, the corresponding cell ID, building ID, unit ID and indoor password are carried at the same time when sending the information. Machine ID. It is not difficult to understand that this information can also be transmitted encrypted.

Step 205, the server 400 receives the information sent by the indoor unit 100, and decrypts the encrypted user password therein.

Step 206, the server 400 generates and stores the required unit VTO password and community VTO password according to the decrypted user password and the cell ID, building ID, unit ID and indoor unit ID carried in the information. Wherein, the password can be generated in the following manner:

Passwords are generated in the form of superimposed characters in turn. Among them, the password of the unit outdoor station is "user password + unit ID"; the password of the community outdoor station is "user password+unit ID+building ID". Of course, characters can also be added if necessary, for example, the password of the unit VTO is "user password + unit ID + building ID";

A specific example is shown in Figure 3, where the cell ID, building ID, unit ID and indoor unit ID correspond to a 2-byte cell number, a 2-byte building number, a 1-byte unit number and The 2-byte room number is respectively community number 01, building number 23, unit number 4, and room number 56. The new user password entered by the user in step 202 is 789999, and the generated unit door phone password is 78999956. The generated The community door phone password is 78999956423.

It should be noted that the above-mentioned password generating method is that the user password (the user password is the password set by the user in step 202) is used in the front, and the following sequence characters are superimposed to generate the password with the unit ID, building ID, and community ID. way, this is because the user passwords of different users are the least likely to be the same, and the identity of unit IDs, building IDs, and cell IDs of different users increases sequentially, and the passwords generated by the password generation method of the present invention are It can quickly judge whether there is an input error, which simplifies the workload of the outdoor station of the community or the outdoor station of the unit. Further examples are given below:

For example, when a user enters the 78999956423 generated according to Figure 3 at the door phone 300 of the community, if he forgets that the user password set by step 202 is wrong when he enters 789999, when he enters the three-digit number "788", he can pass the third password. The number immediately determines that the user has entered an error and prompts the user to re-enter. And if the password generated by the characters of the usual "building number+unit number+room number+user password" is adopted, because usually the user input must be "23456788" eight digits, it can be judged that the user input is wrong and the user is prompted to re-enter ( Because the user usually forgets the user password but does not forget his home address, it is difficult to enter the above-mentioned "23456" normally). It can be seen that the above password generation method not only simplifies the data processing capacity of the device as mentioned above, but also greatly shortens the time to prevent the user from prompting an error after entering a long string of numbers.

Step 207, the server 400 sends the generated cell door phone password to the corresponding cell door phone 300 according to the cell ID; sends the generated cell door phone password to the corresponding cell according to the cell ID, building ID and unit ID The outdoor station 200 is stored by the community outdoor station 300 and the unit outdoor station 200 respectively.

Wherein, for the above step 204, the cell ID, building ID, unit ID and indoor unit ID may not be carried, but these information and the IP address of the indoor unit 100 are stored in the server 400 in advance, and generated in step 206. When the unit VTO password and community VTO password are used, the server 400 queries the community ID, building ID, unit ID and indoor unit ID corresponding to the IP address of the indoor unit 100 needed to generate the password.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention, for example, in step 206, the gate of the community The machine password can also be: building ID+unit ID+user password; the unit door phone password is: unit ID+user password. Alternatively, the password of the community VTO is: community ID + building ID + unit ID + user password; the password of the unit VTO is: building ID + unit ID + user password. These changes should all be included within the protection scope of the present invention.
