Description

Technical Field

[0001] The present invention relates to the technical field of security authentication, and particularly to an air environment main control system based on smart home. Background Art

[0002] With the rise of smart home mobile services, when more and more home appliances such as air conditioners and dehumidifiers are connected to the Internet, it provides a new channel for hackers to cause damage. When hackers invade the control server of smart home, the secure smart home becomes an open home. Therefore, it is necessary to conduct security authentication on the identity of its users before controlling the smart home;

[0003] The existing smart home control platform uses password plus verification code authentication when authenticating home users. The verification code is used to exclude the use of script machines by third parties to obtain authentication rules and crack passwords. Moreover, home users often have a low awareness of password protection, and passwords are easy to leak. If third parties use the leaked passwords to log in, the authentication mechanism of the smart home control platform will completely fail;

[0004] To solve the above problems, the present invention proposes a solution. Summary of the Invention

[0005] The purpose of the present invention is to provide an air environment main control system based on smart home, which solves the problems in the prior art that password plus verification code authentication is used, the verification code is used to exclude the use of script machines by third parties to obtain authentication rules and crack passwords, and home users often have a low awareness of password protection, passwords are easy to leak, and if third parties use the leaked passwords to log in, the authentication mechanism of the smart home control platform will completely fail;

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] An air environment main control system based on smart home includes:

[0008] A regulation and login module for enabling registered and authorized home users to securely log in to the air environment regulation platform;

[0009] The login authentication module obtains the account name and account password entered by the currently pre-logging-in user to log in to the air environment regulation platform, and generates initial request data based on the account name entered by the currently pre-logging-in user to log in to the air environment regulation platform. The initial request data includes two sets of data, namely the account name and a random account password;

[0010] An air environment regulation platform for enabling family members who have passed identity authentication to regulate the air environment in the home;

[0011] The air environment control platform includes an identity authentication unit and a verification code generation unit. The identity authentication unit stores the account names and account passwords of all registered and authorized household users who are allowed to log in to the air environment control platform.

[0012] The identity authentication unit obtains the auxiliary verification account password stored therein that matches the account name carried in the initial request data.

[0013] The verification code generation unit generates a touch verification code for the current pre-login user's current authentication and transmits it to the login authentication module.

[0014] After receiving the touch verification code for the current pre-login user's current authentication transmitted by the verification code generation unit, the login authentication module obtains the click data of the current pre-login user clicking on the touch verification code and generates a security conversion sequence for the current pre-login user according to a certain generation rule, and generates security request data for the current pre-login user based on it and the click data of the current pre-login user.

[0015] The identity authentication unit stores all the touch verification codes generated by the identity authentication unit when the current pre-login user logged in to the air environment control platform in the past. The identity authentication unit generates an authentication verification sequence for the current pre-login user's current login based on all the touch verification codes generated by the identity authentication unit when the current pre-login user logged in to the air environment control platform in the past and the auxiliary verification password stored therein, and compares it with the security request data of the current pre-login user. If the comparison passes, an authentication pass instruction is generated.

[0016] After receiving the comparison pass instruction, the air environment control unit establishes a connection with all the smart homes in the household and provides the current pre-login user with air control parameter settings.

[0017] If the comparison fails, an alarm instruction is generated and transmitted to the mobile device of the household user corresponding to the current pre-login user to alarm it.

[0018] Furthermore, the random account password is a randomly generated 8-14 character string consisting of numbers, letters, and special symbols.

[0019] Furthermore, the verification code generation unit stores a background map set for generating touch verification codes. The background map set contains several landscape images. It should be noted that the landscape images do not contain any digital characters, and the specifications of all landscape images in the background map set are 1920*1080.

[0020] Further, the specific steps for the verification code generation unit to generate the touch verification code for the current pre-login user's current authentication are as follows:

[0021] Step 1: Randomly generate 3 non-repeating numeric characters in sequence, and randomly select a background image from the background image set stored therein as the touch background image for the current authentication;

[0022] Step 2: Randomly fill the 3 non-repeating numeric characters generated randomly into the touch background image for the current authentication to generate the touch verification code for the current authentication;

[0023] It should be noted here that the touch verification code includes touch prompt text below the touch background image, which is used to indicate that the current pre-login user clicks on all the numbers in the specified order, and the positions of the numeric characters in the touch background image are random. The fonts and font sizes of all the numeric characters in the touch background image are the same. The touch prompt text is: Please click on the numbers in sequence + the first number to be clicked + the second number to be clicked + the third number to be clicked.

[0024] Further, when the current pre-login user logged in to the air environment control platform in the past, all the touch verification codes generated by the identity authentication unit and the corresponding receiving times.

[0025] Further, the click data of the current pre-login user includes the positions where the current pre-login user clicks on the touch verification code for the current authentication and the interval duration of each click.

[0053] Advantages of the present invention:

[0054] (1) In the present invention, the login authentication module carries a randomly generated random account password in the initial request data, and uses the characteristic that the current behavior-based verification code is only used to verify whether it is a machine operation to confuse the third party into triggering an incorrect verification, giving timely warnings to household users and ensuring the security of the home;

[0055] (2) In the present invention, the identity authentication unit generates the touch verification code for the current pre-login user for this authentication. The login authentication generates the security conversion sequence for this authentication based on the login password based on all the touch verification codes issued for the past logins of the current pre-login user. The identity authentication unit performs consistency verification on it. On the one hand, it avoids the occurrence of the situation where the third party bypasses the touch verification code and directly uses the account password for background login. On the other hand, it avoids directly transmitting the account password, resulting in the loss of the password. And using the password alone without all the touch verification codes issued for the past logins will trigger an alarm, strengthening the security of controlling the smart home.

[0060] The regulation login module is used for registered and authorized family users to securely log in to the air environment regulation platform;

[0061] The login authentication module obtains the account name and account password entered by the currently pre-logged-in user for logging in to the air environment regulation platform. The login authentication module generates initial request data of the currently pre-logged-in user based on the account name entered by the currently pre-logged-in user for logging in to the air environment regulation platform. The initial request data includes two sets of data, namely the authentication account name and the random account password. The authentication account name is the account name entered by the currently pre-logged-in user for logging in to the air environment regulation platform, and the random account password is an 8-14-digit character randomly generated by numbers, letters, and special symbols;

[0062] The login authentication module transmits the initial request data of the currently pre-logged-in user to the air environment regulation platform;

[0063] The air environment regulation platform is used for authenticated family users to regulate the indoor air environment of the home. The air environment regulation platform includes an identity authentication unit, a verification code generation unit, and an air environment regulation unit;

[0070] After receiving the random generation instruction transmitted by the identity authentication unit, the verification code generation unit randomly generates 3 non-repeating numerical characters in sequence, and randomly selects a background image from the background map set stored therein as the touch background map for this authentication;

[0071] The 3 non-repeating numerical characters randomly generated are randomly filled into the touch background map for this authentication to generate the touch verification code for this authentication. It should be noted that the touch verification code contains touch prompt text below the touch background map, which is used to indicate that the current pre-login user clicks all the numbers in the specified order, and the positions of the numerical characters in the touch background map are random. The fonts and sizes of all numerical characters in the touch background map are the same. In this embodiment, the numerical characters in the touch background map are Song typeface and size 5. In this embodiment, the touch prompt text is: Please click on the numbers in sequence + the first number to be clicked + the second number to be clicked + the third number to be clicked;

[0073] After receiving the touch verification code for the current authentication transmitted by the identity authentication unit, the login authentication module obtains the click data of the currently pre-logged-in user and generates a security conversion sequence for the currently pre-logged-in user according to a certain generation rule. The click data of the currently pre-logged-in user includes the click position of the currently pre-logged-in user and the interval duration between each click.

Otherwise, do nothing. Here, F is a preset comparison threshold;
