4 illustrates a specific embodiment of a multi-system security verification method in accordance with one embodiment of the present invention. flow chart.

As shown in FIG. 4, the multi-system security verification method according to an embodiment of the present invention specifically includes:

Step 402: Set an opening key corresponding to the application that includes multiple fingerprints. The user needs to input multiple fingerprints, and by extracting the corresponding feature values, the fingerprint feature inventory is stored in the secure area. When setting the corresponding application to open or other operations, multiple parameters related to fingerprint verification can be established, and the parameters are stored in the corresponding secure storage area, which is equivalent to the configuration file. Specifically, whether the current terminal is in the security system or the normal system, when the key setting is performed, the environment is switched to the environment of the security system, thereby ensuring the security of the input opening key.

When setting the fingerprint of the relevant application, you can select multiple fingerprints to set. For example, as shown in Figure 5, two fingerprints are used, which are the left and right index fingers of the user. When the user needs to verify, they need to input the corresponding fingerprints in order to verify. This kind of security is much improved compared with the single fingerprint level; in the current FAR and FRR of fingerprint identification, the general range is roughly 1@0000~1/100000 misrecognition rate @1%～3% Rejection rate, that is to say, the security level of a single finger is roughly equivalent to a combination of 4 to 5 digits of pure digits (removing fingerprints is only the user's own unique ID), when the user uses two fingers to superimpose together When verifying the necessary conditions of the same event, it is equivalent to a pure 8-bit secret level, which is equivalent to increasing the security level by multiple times; and so on, 10 fingers can be freely combined, which can greatly improve the security level.

Step 404: When the user needs to use the specified application, click the application icon to open the application interface, and pop up a corresponding fingerprint verification window to prompt the user to perform fingerprint verification. When the application needs to input fingerprints for verification, the user will be prompted to input fingerprints, and the user will be prompted to input. When the first fingerprint is input and verified, it will jump to the input interface of the second fingerprint. After the second fingerprint interface is completed and verified successfully, it enters the third... until the user correctly inputs all the fingerprints, the corresponding operation of the application is directly executed; in order to ensure that other people are not aware of the number of fingerprint combinations set by the user, When the interface is displayed, the user will not be reminded to enter the first few fingerprints. Only the interface will be displayed, please continue to input fingerprints for verification and matching, so as to prevent malicious test attacks; for example, input the first fingerprint. After that, the mark that is not obvious on the interface appears when the first fingerprint has been input, but is represented by another way, such as displaying the progress bar in an irregular manner or the color of the progress bar. Indicates whether the current fingerprint has been verified. For example, when the user inputs the first fingerprint successfully, the display becomes green. When the second fingerprint is input, the display is yellow, etc., so that when the user inputs multiple fingerprints, it can be prevented. Others remember the number of fingerprints set by the owner.

Step 406, verifying that the specified application is run by running, the verification fails, and the specified application is not allowed to enter.

The technical solution of the present invention will be described in detail below by way of a specific example.

Mr. Zhang wants to complete a payment operation with his mobile phone:

1. First, he clicked on the wallet application, entered the setting interface, and set the password mode as fingerprint verification—multiple fingerprint verification;

2. Remind the user to set a combination password with a higher security level as an alternate option when the fingerprint fails.

3. Click to enter the fingerprint and enter the security system. He sets the index finger of his left hand and the index finger of the right hand as the fusion password, and the order is the index finger verification of the right hand. Then the thumb of the left hand is successfully entered and stored in the security system;

4. Open the wallet application and click on the payment for the online shopping product that has just placed the order. At this time, switch to the security system and pop up the verification interface of the user information. On this interface, the first index finger of the right hand is successfully verified. He used the left index finger to verify and succeed. At this time, the application interface displays that the payment has been completed; if the user cannot input the correct verification password, the payment cannot be made.

The technical solution of the present invention is described in detail above with reference to the accompanying drawings. The security level of the fingerprint verification can be improved, and the fingerprint of the user is prevented from being maliciously used or maliciously stolen, thereby comprehensively ensuring the security of the user information in the terminal and improving the user experience.
