[0031] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0032] Example 1:

[0033] The embodiment of the present invention provides an intelligent identity recognition system, which is applied to an Internet of Things platform connected to a smart door lock. Figure 1 As shown, it includes: application module 1, verification module 2, credential generation module 3 and sending module 4;

[0034] Among them, the application module 1 receives the application of the third party; the verification module 2 verifies the owner's identity and the application, and generates an access certificate when the verification is passed; the sending module 4 is used to send the access certificate.

[0035] The owner's identity verification includes one or more combinations of password, facial features, and fingerprint verification.

[0036] The verification module verifies the application through the following procedures:

[0037] Establishing a communication connection with the pre-stored owner's mobile terminal;

[0038] Send application inquiries to the owner's mobile terminal;

[0039] When the received feedback corresponding to the application inquiry is approval, the verification is passed.

[0040] The steps to generate an access credential are as follows:

[0041] Receive the owner's operation information on the access certificate generation interface;

[0042] Generate corresponding access credentials based on the operation information.

[0043] The working principle and beneficial effects of the above technical solution are:

[0044] The steps for achieving access in the smart identity recognition system of this embodiment can be summarized as follows: Step 1: Third-party application: This can be done via any terminal, such as a mobile terminal, phone, or smartwatch; Step 2: The owner verifies the request using their identity credentials, such as a password, face recognition, or fingerprint; Step 3: The requester's access credentials can be sent via SMS, WeChat, or other IM methods, or directly to the smart door lock. The access credentials include a temporary password, the third-party's facial features, or a fingerprint.

[0045] Example 2:

[0046] An embodiment of the present invention provides an intelligent identity recognition system, which is applied to an Internet of Things platform that is communicatively connected to a smart door lock, and includes: an application module, a verification module, a credential generation module, and a sending module;

[0047] Among them, the application module receives the application of the third party; the verification module verifies the owner's identity and application, and generates an access certificate when the verification is passed; the sending module is used to send the access certificate.

[0048] The third party's application is sent by the third party's mobile terminal. The verification module's verification process for the application also includes:

[0049] Output the preset facial action verification process and input the applicant's facial photo.

[0050] The smart identity recognition system of this embodiment is configured in the cloud, that is, on the IoT platform side; the smart door lock is connected to the IoT platform; when an emergency occurs in the home (such as: internal personnel needing rescue, fire fighting, etc.), an external assistant (third party) logs in to the cloud with his mobile terminal (mobile phone), and then performs the corresponding operation of the home entry request. After the operation is completed, the request data of the home entry request is generated and the home entry request is initiated. When the home entry request is received by the home entry request receiving module in the cloud, the request data is verified according to the first verification rule. When it passes, a permission instruction is sent to the mobile terminal, wherein the permission instruction includes a home entry password that can be used and can only be used once; the third party can enter after entering the permission instruction at the smart door lock; through the above-mentioned access mechanism, access after identity recognition is guaranteed in the case of home safety, so that external assistants can enter in the event of an emergency in the home. In addition, the third party's access mechanism can also be configured to be manually enabled by the user, that is, the IoT platform will only verify the home entry request when it receives the temporary access mode of the bound terminal corresponding to the smart door lock. Otherwise, the home entry request is directly rejected.

[0051] Example 3:

[0052] An embodiment of the present invention provides an intelligent identity recognition system, which is applied to an Internet of Things platform that is communicatively connected to a smart door lock, and includes: an application module, a verification module, a credential generation module, and a sending module;

[0053] Among them, the application module receives the application of the third party; the verification module verifies the owner's identity and application, and generates an access certificate when the verification is passed; the sending module is used to send the access certificate;

[0054] The third party's application is sent by the third party's mobile terminal. The verification module's verification process for the application also includes:

[0055] Output the preset facial action verification process and input the applicant's face photo;

[0056] In order to further ensure home security, the intelligent identity recognition system also includes: a positioning acquisition module for obtaining the positioning information of the mobile terminal; a verification module determines the distance between the location corresponding to the positioning information and the smart door lock before verifying the entry request. When the distance is less than or equal to the preset distance threshold, verification is performed; otherwise, it is not performed.

[0057] Since the access permission is granted by the Internet of Things platform authorization method, the identity of the third party is recorded on the platform during the verification process. If the third party is the actual person entering the home, the threat to family safety in this case is relatively small; however, there may be a situation where the third party applying for home entry does not match the actual person entering the home. This situation may pose a greater threat to family safety. This embodiment obtains the positioning information of the mobile terminal before verification, and makes a distance judgment based on a preset distance threshold (any value between 10 meters and 50 meters), thereby reducing the occurrence of situations where the third party does not match the actual person entering the home, thereby further ensuring family safety.

[0058] Example 4:

[0059] An embodiment of the present invention provides an intelligent identity recognition system, which is applied to an Internet of Things platform that is communicatively connected to a smart door lock, and includes: an application module, a verification module, a credential generation module, and a sending module;

[0060] Among them, the application module receives the application of the third party; the verification module verifies the owner's identity and application, and generates an access certificate when the verification is passed; the sending module is used to send the access certificate;

[0061] The third party's application is sent by the third party's mobile terminal. The verification module's verification process for the application also includes:

[0062] Output the preset facial action verification process and input the applicant's face photo;

[0063] In order to further reduce the occurrence of situations where the third party does not match the actual person entering the home, the smart identity recognition system also includes: a tracking module for tracking the location of the third party's mobile terminal after sending a permission instruction to the third party's mobile terminal. When the tracking result does not comply with the pre-configured location movement rules, the permission instruction that has been sent is invalidated. Among them, the judgment of whether the tracking result complies with the pre-configured location movement rules includes: N consecutive location samples are obtained N positions; the ratio of the number of times the distance of the next sampling position to the smart door lock is closer than the previous sampling position to the total number of sampling times is greater than a preset ratio threshold (the ratio threshold is greater than any of 0.6), the tracking result is determined to comply with the pre-configured location movement rules; otherwise, it is determined to be non-compliant; the time interval between each location sampling is pre-configured.

[0064] Example 5:

[0065] An embodiment of the present invention provides an intelligent identity recognition system, which is applied to an Internet of Things platform that is communicatively connected to a smart door lock, and includes: an application module, a verification module, a credential generation module, and a sending module;

[0066] Among them, the application module receives the application of the third party; the verification module verifies the owner's identity and application, and generates an access certificate when the verification is passed; the sending module is used to send the access certificate;

[0067] The third party's application is sent by the third party's mobile terminal. The verification module's verification process for the application also includes:

[0068] Output the preset facial action verification process and input the applicant's face photo;

[0069] In order to further ensure the safety of the family, the intelligent identity recognition system also includes: a risk assessment module for assessing the permission risk of the permission instruction; when the assessed risk value is greater than a preset threshold, the permission instruction is invalidated.

[0070] The risk assessment module evaluates the licensing risk of the licensing instruction in the following steps:

[0071] Determine whether the third party's mobile terminal has a history of home access requests;

[0072] If it exists, retrieve the historical record data and obtain the first evaluation value based on the pre-configured first evaluation library;

[0073] Determine whether there is a requested record for the target corresponding to the home entry request;

[0074] If it exists, retrieve the requested data and obtain a second evaluation value based on a pre-configured second evaluation library;

[0075] The first evaluation value and the second evaluation value are combined to obtain an assessed risk value.

[0076] Additionally, when a facial photo matches any standard photo in a pre-configured whitelist library, no authorization risk assessment is required.

[0077] Example 6:

[0078] An embodiment of the present invention provides an intelligent identity recognition system, which is applied to an Internet of Things platform that is communicatively connected to a smart door lock, and includes: an application module, a verification module, a credential generation module, and a sending module;

[0079] Among them, the application module receives the application of the third party; the verification module verifies the owner's identity and application, and generates an access certificate when the verification is passed; the sending module is used to send the access certificate;

[0080] The third party's application is sent by the third party's mobile terminal. The verification module's verification process for the application also includes:

[0081] Output the preset facial action verification process and input the applicant's face photo;

[0082] In addition, the entry request receiving module can also directly receive the entry request from the smart door lock. When the entry request receiving module receives the entry request through the smart door lock, the image acquisition module connected to the communication with the smart door lock collects the image of the person operating the smart door lock and adds it to the request data; the verification module verifies the person image in the request data based on the preset verification rules; when the verification is passed, an opening instruction is sent to the smart door lock.

[0083] The verification module verifies the person image in the request data based on preset verification rules, specifically including:

[0084] Extract features from person images, obtain person feature parameters, and construct a person feature set based on the person feature parameters;

[0085] When the personnel feature set matches the verification feature set in the verification library corresponding to the preset verification rules, the verification is passed;

[0086] The personnel characteristic parameters include: parameters indicating the number of personnel, parameters indicating the characteristics of personnel clothing, and parameters indicating the types of items carried by personnel. The personnel characteristic parameters of firefighters are pre-added to the verification library, so that firefighters can directly verify and enter the building when a fire occurs.

[0087] Since verification is performed using a verification library, any specific type of person who has been pre-registered in the verification library can enter after verification. This raises many issues such as privacy and security. How to balance privacy and access in emergency situations such as firefighting? A data acquisition module and an event analysis module can be configured. The data acquisition module can be connected to various environmental perception sensors configured indoors to collect sensor data; the event analysis module is used to analyze the collected sensor data to determine whether an event has occurred; among them, the environmental perception sensor includes one or more combinations of a smoke sensor, a temperature sensor, and a humidity sensor. In this way, the analysis of indoor events is achieved through the cooperation of the data acquisition module and the event analysis module. On the basis of the event analysis, each verification feature set corresponding to the event in the verification library is set to available, otherwise it is set to unavailable; at this time, the verification library configuration module needs to be operated, and the verification library configuration module configures the start and stop parameters for each verification feature set in the verification library; the start and stop parameters are 1, indicating available; the start and stop parameters are 0, indicating unavailable; the verification library configuration module can set the start and stop parameters to 0 and 1 according to the event analysis results; it is necessary to use the pre-configured association library of events and verification feature sets; the start and stop parameters in the verification library are changed through the association relationship in the association library.

[0088] For some other special cases, a restriction release trigger device (button) can be configured indoors. When the restriction release trigger device is triggered, the smart door lock can be opened directly without verification. The main response scenarios set here are as follows: 1. When there is someone in the house when a fire occurs, to prevent one of the people in the house from opening the door in a panic, but there are other people in the house, and other people outside the house need verification to enter, the people in the house trigger the restriction release trigger device to allow other people outside the house to enter directly; 2. When there is someone in the house when a fire occurs, there is a very short reaction time in the early stage of the fire, or the people are trapped, that is, no one comes out of the house. At this time, the people in the house trigger the restriction release trigger device to allow other people outside the house to enter directly.

[0089] In addition, a do not disturb control module can also be configured, which includes: an entry person identification unit, a time analysis unit, and a do not disturb control unit; the entry person identification unit is used to identify the person entering the house. When the person entering the house on the same day meets all the people associated with the pre-configured house (that is, all family members have entered the house), it outputs a first signal with positive feedback; when the time analysis unit determines that the current time falls within the pre-configured time range, it outputs a second signal with positive feedback; when the do not disturb control unit receives both the first signal and the second signal as positive, it enters the do not disturb mode and suspends the application verification of the third party, that is, rejects the application of the third party. Through the do not disturb mode, it ensures that the people in the house are not disturbed for a period of time. It is usually used when family members go home to sleep, so that there is no disturbance from other people applying to enter.

[0090] Example 7:

[0091] The present invention also provides an emergency door opening control method for an intelligent door lock, such as Figure 2 Shown, including:

[0092] Step 1: Receive the third party's application;

[0093] Step 2: Verify the owner's identity and application, and generate an access certificate when the verification is successful;

[0094] Step 3: Send access credentials.

[0095] Among them, the access credentials include: one or more combinations of passwords, facial features, and fingerprints.

[0096] The verification module verifies the application through the following procedures:

[0097] Establishing a communication connection with the pre-stored owner's mobile terminal;

[0098] Send application inquiries to the owner's mobile terminal;

[0099] When the received feedback corresponding to the application inquiry is approval, the verification is passed.

[0100] The steps to generate an access credential are as follows:

[0101] Receive the owner's operation information on the access certificate generation interface;

[0102] Generate corresponding access credentials based on the operation information.

[0103] Example 8:

[0104] The present invention also provides an emergency door opening control method for a smart door lock, wherein the application by the third party is issued by a mobile terminal used by the third party; the verification process of the application by the verification module further includes:

[0105] Output the preset facial action verification process and input the applicant's face photo;

[0106] In addition, the emergency door opening control method of the smart door lock also includes:

[0107] Obtaining positioning information of the mobile terminal;

[0108] Before verifying the entry request, determine the distance between the location corresponding to the positioning information and the smart door lock. When the distance is less than or equal to the preset distance threshold, perform the verification; otherwise, do not perform the verification.

[0109] In addition, the emergency door opening control method of the smart door lock also includes: tracking the position of the third party's mobile terminal after sending the permission instruction to the third party's mobile terminal, and when the tracking result does not meet the pre-configured position movement rules, setting the sent permission instruction to invalid.

[0110] In addition, the emergency door opening control method of the smart door lock also includes: evaluating the permission risk of the permission instruction; when the evaluated risk value is greater than a preset threshold, setting the permission instruction to be invalid.

[0111] The steps for assessing the licensing risk of a licensing directive are as follows:

[0112] Determine whether the third party's mobile terminal has a history of home access requests;

[0113] If it exists, retrieve the historical record data and obtain the first evaluation value based on the pre-configured first evaluation library;

[0114] Determine whether there is a requested record for the target corresponding to the home entry request;

[0115] If it exists, retrieve the requested data and obtain a second evaluation value based on a pre-configured second evaluation library;

[0116] The first evaluation value and the second evaluation value are combined to obtain an assessed risk value.

[0117] In addition, the emergency door opening control method of the smart door lock also includes: when the facial photo matches any standard photo in a pre-configured whitelist library, there is no need to evaluate the permission risk.

[0118] In addition, the emergency door opening control method of the smart door lock also includes: when the smart door lock receives an entry request, the image of the person operating the smart door lock is collected by an image acquisition module connected to the communication with the smart door lock and added to the request data; the person image in the request data is verified based on preset verification rules; when the verification is passed, an opening instruction is sent to the smart door lock.

[0119] The person image in the request data is verified based on preset verification rules, specifically including:

[0120] Extract features from person images, obtain person feature parameters, and construct a person feature set based on the person feature parameters;

[0121] When the personnel feature set matches the verification feature set in the verification library corresponding to the preset verification rules, the verification is passed;

[0122] The personnel characteristic parameters include: parameters indicating the number of personnel, parameters indicating the characteristics of personnel clothing, and parameters indicating the types of items carried by personnel.

[0123] Since verification is performed using a verification library, any specific type of person who has been pre-registered in the verification library can enter after verification, which raises many issues such as privacy and security. In order to achieve both privacy and access in emergency situations such as fire, the emergency door opening control method of the smart door lock also includes: collecting sensor data by connecting with various environmental perception sensors configured in the room; analyzing the collected sensor data to determine whether an event has occurred; based on the event analysis, setting each verification feature set corresponding to the event in the verification library to available, otherwise setting it to unavailable; configuring each verification feature set in the verification library with start and stop parameters; the start and stop parameters are 1, indicating available; the start and stop parameters are 0, indicating unavailable; setting the start and stop parameters to 0 and 1 according to the event analysis results; it is necessary to use a pre-configured association library of events and verification feature sets; and changing the start and stop parameters in the verification library through the association relationship in the association library; wherein, the environmental perception sensor includes one or more combinations of smoke sensors, temperature sensors, and humidity sensors.

[0124] For some other special situations, the emergency door opening control method of the smart door lock also includes: when a trigger signal indicating that the restriction release trigger device is triggered is received, the smart door lock is placed in a state where it can be opened directly without verification; the restriction release trigger device (button) is configured indoors; the main response scenarios set here are as follows: 1. When there is someone in the house when a fire occurs, to prevent one of the people in the house from opening the door in a panic, but there are other people in the house, and other people outside the house need verification to enter, the people in the house trigger the restriction release trigger device to allow other people outside the house to enter directly; 2. When there is someone in the house when a fire occurs, there is a very short reaction time in the early stage of the fire, or the people are trapped, that is, no one comes out of the house. At this time, the people in the house trigger the restriction release trigger device to allow other people outside the house to enter directly.

[0125] In addition, the emergency door opening control method of the smart door lock also includes: identifying people entering the house, and when the people entering the house on the same day meet all the people associated with the pre-configured house (that is, all family members have entered the house), outputting a first signal with positive feedback; when the time analysis unit determines that the current time falls within the pre-configured time range, outputting a second signal with positive feedback; when both the first signal and the second signal are positive, entering the do not disturb mode, suspending the application verification of the third party, that is, rejecting the application of the third party; through the do not disturb mode, it is guaranteed that the people in the house are not disturbed for a period of time, which is usually used when family members go home to sleep, so that there is no disturbance from other people applying to enter.

[0126] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
