[0046] The safe unlocking method of the smart door lock described in the preferred embodiment of the present invention is as follows: Figure 1 As shown, the safe unlocking method of the smart door lock comprises the following steps:

[0047] Step S10: When it is detected that the user is in a preset unlocking range, an identity authentication instruction is generated, and the user is prompted to perform identity authentication according to the identity authentication instruction.

[0048] Specifically, in an embodiment of the present invention, when a user approaches a smart door lock, it is detected that the user is in a preset unlocking range (for example, 1 meter), the corresponding authentication process is activated, and an identity authentication instruction is generated, and the user is prompted to perform identity authentication according to the identity authentication instruction.

[0049] Furthermore, when the user is prompted to perform identity authentication, a timing operation is performed. If the user is not detected to perform authentication within a preset time, a sleep instruction is generated. The corresponding authentication process is closed according to the sleep instruction, and the current operating state of the smart door lock is switched to the sleep state, thereby saving energy loss and extending the service life.

[0050] Step S20: Acquire multiple authentication factors of the user, perform correlation verification on all the authentication factors to obtain a target verification result, and perform security analysis on the target verification result to obtain a security analysis result.

[0051] The step S20 comprises:

[0052] Step S21: when the user is prompted to perform identity authentication, obtain the user's identity information, and perform matching processing on the identity information to obtain a first verification result;

[0053] Step S22: If the first verification result is a successful match, the user is prompted to perform password authentication, the password information input by the user is obtained, and the password information is verified to obtain a second verification result;

[0054] Step S23: If the second verification result is successful, the user is prompted to perform physical token verification, obtain corresponding physical token information, and identify the physical token information to obtain a third verification result;

[0055] Step S24: if the third verification result is verification passed, respectively obtain the first verification time and the first verification order of the first verification result, the second verification time and the second verification order of the second verification result, and the third verification time and the third verification order of the third verification result;

[0056] Step S25: performing authentication duration analysis on the first authentication duration, the second authentication duration, and the third authentication duration according to the preset completion time to obtain a duration analysis result;

[0057] Step S26: Perform authentication sequence analysis on the first authentication sequence, the second authentication sequence and the third authentication sequence according to a preset authentication sequence to obtain a sequence analysis result.

[0058] Specifically, in an embodiment of the present invention, when the user is detected to be authenticating within a preset time, it is necessary to obtain the authentication factors of the user, wherein the authentication factors include identity information, password information and physical token information, and the identity information includes but is not limited to fingerprint information, facial information and iris information, and fingerprint information is used as an example. The specific authentication process is that when the user is prompted to perform fingerprint authentication and the user places the finger on the corresponding fingerprint sensor within the preset time, the fingerprint information of the user's current finger is collected, and the fingerprint information is matched, that is, the collected fingerprint information is compared with the pre-stored fingerprint template. Yes, get the first verification result; if the first verification fails to match, that is, the collected fingerprint information does not match the pre-stored fingerprint template, then record the corresponding number of failures, and compare the number of failures with the preset number (for example, 3 times); if the number of failures is less than the preset number, generate a re-authentication instruction, and prompt the user to perform identity authentication according to the re-authentication instruction; if the number of failures is greater than or equal to the preset number, generate an early warning reminder, and trigger the corresponding alarm mechanism according to the early warning reminder, so as to promptly remind the target user to handle the exception, wherein the target user is the user bound to the smart door lock.

[0059] If the first verification result is a successful match, the user is prompted to perform password authentication, that is, the user is prompted to enter a preset number (for example, 6 digits) of digital passwords through the display screen of the smart door lock, the password information entered by the user is obtained, and the password information is verified to obtain a second verification result; if the second verification result is a verification failure, that is, the password information entered by the user is different from the pre-stored unlocking password, the corresponding number of failures is recorded, and the number of failures is compared with the preset number (for example, 3 times); if the number of failures is less than the preset number, a re-authentication instruction is generated, and the user is prompted to re-enter the password according to the re-authentication instruction; if the number of failures is greater than or equal to the preset number, an early warning reminder is generated, and the corresponding alarm mechanism is triggered according to the early warning reminder, so as to promptly remind the target user to handle the abnormality.

[0060] If the second verification result is successful verification, the user is prompted to perform physical token verification (for example, NFC smart card). When the user brings the corresponding NFC smart card close to the sensing area of ​​the smart door lock, the corresponding physical token information is read, and the physical token information is identified and processed to obtain a third verification result; if the third verification result is verification failure, that is, the collected fingerprint information does not match the pre-stored fingerprint template, the corresponding number of failures is recorded, and the number of failures is compared with the preset number (for example, 3 times); if the number of failures is less than the preset number, a re-authentication instruction is generated, and the user is prompted to re-verify the physical token information according to the re-authentication instruction; if the number of failures is greater than or equal to the preset number, an early warning reminder is generated, and the corresponding alarm mechanism is triggered according to the early warning reminder, so as to promptly remind the target user to handle the abnormality.

[0061] If the third verification result is verification passed, it is necessary to perform corresponding security analysis on the above-mentioned authentication factors, wherein the security analysis includes authentication duration analysis and authentication sequence analysis; the specific security analysis process is to respectively obtain the first authentication time and the first authentication sequence of the first verification result, the second authentication time and the second authentication sequence of the second verification result, and the third authentication time and the third authentication sequence of the third verification result; perform authentication duration analysis on the first authentication duration, the second authentication duration and the third authentication duration according to the preset completion time (for example, 30s) to obtain a duration analysis result; perform authentication sequence analysis on the first authentication sequence, the second authentication sequence and the third authentication sequence according to a preset authentication sequence (for example, biometric authentication, password authentication, physical token authentication) to obtain a sequence analysis result.

[0062] Furthermore, in an embodiment of the present invention, the security analysis also includes suspicious operation analysis, and the security analysis result also includes abnormal analysis results, and suspicious operation analysis is performed on the first verification result, the second verification result, and the third verification result to obtain abnormal analysis results.

[0063] Further, after obtaining the duration analysis result, the sequence analysis result and the abnormality analysis result, it is necessary to determine whether the security analysis result meets the preset security standard. Specifically, if the duration analysis result is that the preset completion time is not exceeded, the sequence analysis result is that the preset authentication sequence is met, and the abnormality analysis result is that no suspicious operation exists, then the security analysis result is determined to meet the preset security standard; if any one of the duration analysis result, the sequence analysis result and the abnormality analysis result does not meet the condition, that is, if the duration analysis result is that the preset completion time is exceeded, the sequence analysis result is that the preset authentication sequence is met, and the abnormality analysis result is that no suspicious operation exists;

[0064] Or, if the duration analysis result is that the preset completion time is not exceeded, the sequence analysis result is that the preset authentication sequence is not met, and the abnormality analysis result is that no suspicious operation exists;

[0065] Or, if the duration analysis result is that the preset completion time is not exceeded, the sequence analysis result is that the preset authentication sequence is met, and the abnormality analysis result is that there is a suspicious operation;

[0066] Or, if the duration analysis result is that the preset completion time is exceeded, the sequence analysis result is that the preset authentication sequence is not met, and the abnormality analysis result is that no suspicious operation exists;

[0067] Or, if the duration analysis result is that the preset completion time is not exceeded, the sequence analysis result is that the preset authentication sequence is met, and the abnormality analysis result is that there is a suspicious operation;

[0068] Or, if the duration analysis result is that the preset completion time is not exceeded, the sequence analysis result is that the preset authentication sequence is not met, and the abnormality analysis result is that there is a suspicious operation;

[0069] Alternatively, if the duration analysis result is that the preset completion time is exceeded, the sequence analysis result is that the preset authentication sequence is not met, and the exception analysis result is that there is a suspicious operation, then the security analysis result is determined to be not in compliance with the preset security standards, and the corresponding abnormal situation is recorded, and the corresponding alarm mechanism is triggered, so as to promptly remind the target user to handle the exception.

[0070] Step S30: If the security analysis result meets the preset security standard, an unlocking instruction is generated, and unlocking is performed according to the unlocking instruction.

[0071] Specifically, if the security analysis result meets the preset security standard, a corresponding unlocking instruction is generated and the unlocking instruction is authorized; thereafter, the authorized unlocking instruction is executed, that is, the door lock is opened by driving the lock cylinder through the door lock motor of the smart door lock; the present invention significantly improves the security of the smart door lock by verifying the correlation of multiple authentications, greatly reduces the risk of unauthorized access, and multiple authentications also increase the difficulty and cost of cracking for attackers, and the comprehensive analysis mechanism can identify abnormal unlocking operation behaviors, further enhancing the security of smart door lock unlocking.

[0072] Furthermore, the present invention can also be flexibly configured according to actual needs, for example, adjusting the type and number of authentication factors, or setting different security levels according to different usage scenarios, so that the flexible configuration options make the present invention suitable for scenarios with different security requirements.
