Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The embodiment of the application provides an access control verification method, and in a first embodiment of the access control verification method, referring to fig. 1, the access control verification method is applied to a verification component, and the method includes:

step S10, reading an identification code of a first user for epidemic prevention verification to obtain identification code information, and sending the identification code information to a back-end platform, wherein the back-end platform collects first epidemic prevention data of the first user, and the first epidemic prevention data comprises first face information of the first user and first health code data of the first user;

step S20, receiving first epidemic prevention data of the first user fed back by the backend platform based on the identification code information;

step S30, collecting second face information within a preset image collecting range, and carrying out one-to-one comparison on the second face information and the first face information;

step S40, if the first similarity between the second face information and the first face information is greater than or equal to a first preset threshold, determining whether to issue an opening instruction to the access control device based on the first epidemic prevention data of the first user.

The present embodiment is intended to: during the epidemic prevention verification, the consistency of the human codes in the verification process is ensured, and the verification accuracy is improved.

The method comprises the following specific steps:

as an example, the access control verification method may be applied to an access control verification device belonging to a verification component belonging to an access control verification system belonging to an access control verification device.

As an example, the access verification system further includes a backend platform and an access control device.

As an example, the verification component and the backend platform are combined to perform people code consistency verification on the user and perform epidemic prevention data verification on the people, and after the people code consistency verification and the epidemic prevention data verification are passed, the verification component controls the entrance guard equipment to be opened so as to pass the verified user.

As an example, the verification component may be a human face device, as shown in fig. 4, or may be a device for recognizing other biometric features of the user, and the like, and is not limited in this respect.

As an example, the verification assembly includes a camera, the camera is used for scanning the two-dimensional code and collecting face information, and the camera body in the verification assembly may be: the types of standard definition cameras, high definition cameras, and the like are not particularly limited.

As an example, the access control device includes a door lock, a gate, and the like, which is not limited in particular.

As an example, the access control verification method may be applied to places such as subways, buses, shopping malls, hospitals, and the like.

As an example, the access control verification method is applied to a control scene requiring strict epidemic situations.

As an example, the verification component determines the local epidemic prevention configuration, and if the local epidemic prevention configuration is forced to wear the mask or forced to be normal in body temperature, the verification component needs to perform mask identification and body question detection before the face comparison, and can perform the subsequent face comparison verification process after the determination is passed.

The verification component reads the identification code of the first user for epidemic prevention verification to obtain identification code information.

As an example, the verification component main interface guides the user to expose an identification code for verification.

As an example, the identification code may be a two-dimensional code or a barcode, and is not limited specifically.

As an example, the identification code may be a health code, an health code, a reissue code, and the like, which are placed in the terminal application for epidemic prevention verification.

As an example, the identification code may be generated by information output by the first user after scanning a two-dimensional code for epidemic prevention verification.

As an example, the verification component is externally connected with an identification code reader in different external connection modes, and the step of reading the identification code of the first user for epidemic prevention verification to obtain the identification code information includes:

step S11, reading the identification code of the first user for epidemic prevention verification through the identification code reader;

As an example, the verification component is externally connected with an identification code reader (two-dimensional code reader) through different external connection modes, such as external RS485 (a connection mode), external RS232 (a connection mode), external USB and the like, and is externally connected with an identification code scanning gun (a type of two-dimensional code reader) through the external RS485, the external RS232, the external USB and the like, so as to identify a corresponding identification code.

Wherein, set up the aim at of external RS485 (a mode of connection), external RS232 (a mode of connection) and external USB etc. in verifying the subassembly: the camera identification is prevented from being inaccurate or the identification speed is prevented from being too slow.

As an example, the verification component performs encryption and decryption processing or transparent transmission processing on the read identification code information, and sends the processed data to the back-end platform, where how to process the identification code information needs to complete negotiation between the verification component and the back-end platform, so that after the verification component performs encryption and decryption processing or transparent transmission processing on the identification code information, the back-end platform can decrypt or receive the information to obtain corresponding data.

As an example, since the encryption and decryption operations are time consuming, if the backend platform processes a large amount of identification code information, the load is too large, and therefore, after the verification component reads the identification code information, the verification component locally decrypts the identification code information to obtain the key data in the identification code information, and uploads the key data to the platform, so that the resource consumption of the backend platform for encryption and decryption is reduced.

As an example, the backend platform directly reads only the key data in the identification code information, so that the resource consumption of the backend platform for encryption and decryption is reduced, and the security effect of the method is stronger.

After the verification component reads the identification code information, the identification code information is sent to a back-end platform in communication connection with the verification component, wherein the back-end platform can be a cloud platform.

As an example, the backend platform collects first epidemic prevention data of each user (including the first user), wherein the first epidemic prevention data comprises first face information of each user and first health code data of the first user.

As an example, the face information is a face picture or a face feature value, where the face feature value includes less face data, and the data amount of the face feature value is smaller than that of the face picture.

As an example, the face feature value may be a face contour feature value, a face facial feature value, and the like.

As an example, the first epidemic prevention data includes first health code data including health code status, person trip information, vaccination information, vaccine antibody information, nucleic acid detection information, and the like, in addition to the first face information.

As an example, the back-end platform has a corresponding front-end app, each user completes a health application in the front-end app and completes uploading of a face picture, the back-end platform verifies the health application of the user through the platform end or the device interface and verifies a picture uploaded by the user, and after the picture uploaded by the user passes verification, corresponding first face information is stored.

As an example, the backend platform may collect the corresponding first facial information only after the user agrees with the privacy protocol.

As an example, when each user performs a face picture in the front-end app, the face picture needs to be checked based on preset personnel modeling requirements, and if the face picture meets the modeling requirements, the face picture is uploaded.

in this embodiment, after receiving the identification code information, the backend platform acquires the first epidemic prevention data of the corresponding first user based on the identification code information.

As an example, the backend platform performs data retrieval based on the identification code information of the first user, and obtains first epidemic prevention data, including information such as terminal information, health code status, and first facial information, stored by the first user on the backend platform.

As an example, the backend platform employs encryption when returning the first epidemic prevention data to the verification component.

after receiving the first epidemic prevention data, the verification component calls a camera shooting function of the camera to shoot the face (shoot the face in the acquisition range of the camera), and second face information is obtained.

As an example, after the user scans the code, the verification component reminds the corresponding person to approach the device camera to collect the second face information.

And after second face information is obtained, performing one-to-one comparison on the second face information and the first face information.

Wherein the one-to-one comparing the second face information and the first face information comprises:

in a first mode, a second face image in the second face information and a first face image in the first face information are compared one to one;

or in a second mode, performing one-to-one comparison on the second face characteristic value in the second face information and the first face characteristic value in the first face information.

As an example, a one-to-one comparison may be performed between a second face feature value in the second face information and a first face feature value in the first face information, so that the verification component and the backend platform may interact with less face data, and the interaction speed is increased.

In this embodiment, one-to-one refers to: and comparing the face picture acquired on site with a known face picture to obtain the similarity, comparing the similarity with a set similarity threshold, and judging whether the person acquiring the face picture on site is the person acquiring the face picture on known.

And if the first similarity between the second face information and the first face information is greater than or equal to a first preset threshold value, determining that the first user corresponding to the second face information is the same as the user corresponding to the first face information.

And after the confirmation of the same person, the verification component determines whether to issue an opening instruction to the access control equipment based on the first epidemic prevention data of the first user.

As an example, if the health code of the first user in the first epidemic prevention data is a green code, it is determined to issue an opening instruction to the access control device.

As an example, if the health code of the first user in the first epidemic prevention data is a green code, that is, when the verification passes, the corresponding verification result is also displayed on the liquid crystal screen of the access control device or the device corresponding to the verification component.

As an example, the liquid crystal screen is partially hidden from personal sensitive information such as names of people, and information leakage is prevented.

As an example, the verification component determines whether to issue an opening instruction to the access control device based on the first epidemic prevention data of the first user and the local epidemic prevention configuration.

As an example, if the local epidemic prevention is configured to forcibly wear a mask, after determining that the health code of the first user is a green code, it is also determined whether the first user wears the mask, and if the first user wears the mask, it is determined to issue an opening instruction to the access control device.

As an example, the local epidemic prevention configuration may further include other configuration information such as human detection, user body temperature information, and the like, which is not limited specifically.

As an example, the access control device opens the door path and passes the first user when receiving the opening instruction of the verification component.

In this embodiment, ensure that the people code is the uniformity after, again based on first user's first epidemic prevention data, confirm whether to issue opening instruction and give entrance guard's equipment, avoid other people user to acquire other people health code, and then get into the condition in corresponding place, therefore promote epidemic situation verification degree of accuracy, reduce epidemic situation prevention and control risk.

Wherein before receiving first epidemic prevention data of the first user fed back by the backend platform based on the identification code information, third face information of the first user is also collected,

referring to fig. 2, the step of comparing the second face information with the first face information in a one-to-one manner includes the following steps S31-S32:

step S31, comparing the third face information with the second face information;

step S32, if the second similarity between the third face information and the second face information is greater than or equal to a second preset threshold, performing a one-to-one comparison between the second face information and the first face information, where the second preset threshold is greater than or equal to the first preset threshold.

In this embodiment, the application scenario for which the method is applied is as follows:

due to the influences of makeup, wearing and the like of the user, the first face information and the second face information collected by the verification component are different (it is determined that the first preset threshold value cannot be set too high), that is, the first preset threshold value only ensures the accuracy of the person code verification under the normal state. In a special or extreme case, for example, if two twins or a person with a similarity greater than a first preset threshold is replaced (in the case that a and B are extremely similar, the similarity between the first face information stored by the a user on the backend platform and the second face information of the B user collected by the a user may be greater than or equal to the first preset threshold), based on the first preset threshold (the first preset threshold is 70% similar), the second face information and the first face information are compared in a one-to-one manner, and the person code check consistency cannot be ensured.

In this embodiment, in the abnormal situation, the human code verification consistency is ensured.

Under the abnormal condition, in order to ensure the consistency of the person code verification, the verification component collects the third face information of the first user before receiving the first epidemic prevention data of the first user fed back by the back-end platform based on the identification code information.

The third face information is a third face image or third face information.

After third face information is collected, comparing the third face information with the second face information, and if the second similarity between the third face information and the second face information is greater than or equal to a second preset threshold, the user corresponding to the third face information and the user corresponding to the second face information are the same user. In this embodiment, since the third face information and the second face information are collected at short time intervals, and are not affected by makeup, wearing, and the like of the user, the second preset threshold is larger than the first preset threshold, and since the second preset threshold (the second preset threshold is 95% similar) is larger than the first preset threshold (the first preset threshold is 70% similar), the consistency of the human code verification in the abnormal state is ensured (in the case where the similarity between the a user and the B user is larger than the first preset threshold, the similarity between the first face information stored in the backend platform by the a user and the second face information collected by the B user is still smaller than the second preset threshold).

And if the user corresponding to the third face information and the user corresponding to the second face information are the same user, performing one-to-one comparison on the second face information and the first face information, and if the user corresponding to the third face information and the user corresponding to the second face information are not the same user, not performing one-to-one comparison on the second face information and the first face information so as to save a comparison process.

Overall, the present embodiment aims at: during the epidemic prevention verification, under the abnormal condition, the consistency of the human codes in the verification process is ensured, and the verification accuracy is improved.

The application provides a door control verification method, a system, equipment and a storage medium, compared with the existing epidemic situation prevention and control period, the people code consistency verification is carried out manually by security personnel, so that the people code consistency verification accuracy during the epidemic situation verification is not high, and the epidemic situation prevention and control risk is high, in the application, after a first user scans an identification code for epidemic prevention verification, a verification component sends the read identification code information to a rear-end platform (the consistency of the terminal information of the current verification and the terminal information collected by the rear-end platform is ensured), the receiving rear-end platform returns the identification code information corresponding to first epidemic prevention data (including first face information, obviously, second face information is bound with the terminal information collected by the rear-end platform) to the verification component, in the process, the verification component collects the second face information within a preset image collection range, and compares the second face information with the first face information, if first face information with the first similarity more than or equal to first preset threshold value of second face information, this moment, first face information with second face information is unanimous, and because the terminal information of current verification is unanimous with the terminal information that the rear end platform gathered, it is very obvious, the terminal information and the first face information of current verification are unanimous, promptly, ensure that the people's code is the uniformity, after ensuring that the people's code is the uniformity, again based on first user's first epidemic prevention data, confirm whether to issue opening instruction and give entrance guard's equipment, avoid other people's user to acquire other people's health code, and then get into the condition in corresponding place, therefore promote the epidemic situation verification degree of accuracy, reduce epidemic situation prevention and control risk.

in this embodiment, if the first similarity between the second face information and the first face information is smaller than the first preset threshold, it is determined that the first user face epidemic prevention verification fails, after it is determined that the first user face epidemic prevention verification fails, the face authentication process is completed, at this time, the verification component calls the pre-stored first information and outputs the first information, where the first information includes information that the first user is inconsistent with the back-end platform user, and the information reminds the first user to rescan the identification code for epidemic prevention verification, so as to save the verification process.

In this embodiment, if the second similarity is smaller than the second preset threshold, it is determined that the face anti-epidemic verification of the first user fails, and the face anti-epidemic verification fails because the face of the first user is replaced, after it is determined that the face anti-epidemic verification of the first user fails, the face authentication process is completed, at this time, the verification component calls the pre-stored second information and outputs the second information, where the second information includes information that the face of the first user is replaced, and information that prompts the first user to re-scan the identification code for anti-epidemic verification.

In this embodiment, as long as it is determined that the face epidemic prevention verification of the first user fails, it is determined that the face code verification fails, and verification of other epidemic prevention data is not performed, so as to save a verification process.

Wherein after the step of determining that the face epidemic prevention verification of the first user fails, the method comprises:

and step B1, deleting the second face information, the third face information and the first epidemic prevention data in a preset time period after the face verification fails.

In this embodiment, the application scenarios targeted are:

scene one: the internal storage space of the verification component is limited, and the verification is slow due to the fact that epidemic prevention data are stored.

Scene two: the verification component stores user data, and it is difficult to ensure privacy of user information.

In this embodiment, if it is determined that the face epidemic prevention verification of the first user fails based on the information that the first similarity between the second face information and the first face information is smaller than the first preset threshold, the second face information, the third face information, and the first epidemic prevention data are deleted within a preset time period, for example, within 1 s.

Or based on the information that the second similarity is smaller than the second preset threshold, after the face epidemic prevention verification of the first user fails, deleting the second face information, the third face information and the first epidemic prevention data within a preset time period, such as 1 s.

As an example, the verification component stores the second face information, the third face information and the first epidemic prevention data in a cache, and deletes the second face information, the third face information and the first epidemic prevention data in the cache when the verification component is powered off.

In the embodiment, the verification component does not store the face data and epidemic prevention data of the user, so that the verification is prevented from being slow, and the privacy of the user is prevented from being revealed.

Further, based on the first embodiment and the second embodiment in the present application, another embodiment of the present application is provided, in which after the step of determining that the face epidemic prevention verification of the first user fails, the method includes:

step C1, if the number of times of the face epidemic prevention verification failure of the first user exceeds the preset number of times, determining whether request information for requesting to start an acquisition mode by a management user is received;

step C2, if the request information is received, acquiring the target face information of the first user based on the acquisition mode;

and step C3, uploading the target face information to the back-end platform, so that the back-end platform can update the first epidemic prevention data based on the target face information.

In this embodiment, the application scenarios targeted are:

the first user cannot check the first face data stored in the back-end platform, or the first face data is identified by the check component, so that remedial measures need to be taken.

As an example, the preset number of times may be 3 times.

As an example, the remedial action may be: if the field worker (management user) judges that the user is the holder, the field worker sends an opening instruction to the access control device through the verification component, so that the access control device can open the access control device to allow the first user to pass.

As an example, when the field worker issues the opening instruction to the access control device through the verification component, the field worker requests the management authority through a request button on the verification component (the verification component may collect and judge the face of the field worker to determine whether to issue the management authority to the field worker). If the field working personnel (management user) obtains the management authority, the request information of requesting to start the acquisition mode is triggered to the verification component through the management authority.

As an example, if the verification component receives the request information, the target face information of the first user is collected based on the collection mode, and the target face information is uploaded to the backend platform, so that the backend platform updates the first epidemic prevention data based on the target face information.

As an example, after the first user updates the first epidemic prevention data at the backend platform, the first user performs a verification here.

As an example, the collection mode may also be started based on the mobile terminal, the first face information of the first user is collected and uploaded to the backend platform for the first epidemic prevention data of the backend platform, and after the first user updates the first epidemic prevention data on the backend platform, the first user performs the verification here.

In the embodiment, remedial measures are taken for users who fail to pass the people code verification for many times, so that convenience is provided for the users to pass.

Further, based on the first embodiment, the second embodiment and the third embodiment in the present application, another embodiment of the present application is provided, in which the face information is a face image, and the access control verification method further includes:

step S50, determining a face pitch angle, a face deflection angle and an eye distance of a second face image, and determining a second quality score of the second face image based on the face pitch angle, the face deflection angle and the eye distance of the second face image;

step S60, determining a face pitch angle, a face deflection angle and an eye distance of a third face image, and determining a third quality score of the third face image based on the face pitch angle, the face deflection angle and the eye distance of the third face image;

step S70, selecting a target quality score from the first quality score, the second quality score and the first quality score;

step S80, sending the face information corresponding to the target quality score to the backend platform, so that the backend platform updates the face information corresponding to the epidemic prevention data.

In this embodiment, the application scenarios targeted are:

if the first face information acquired by the rear-end platform is the face information with the lowest requirement, and if the first face information acquired by the rear-end platform is the face information with the lowest pixel requirement, the comparison consumes too long time or is inaccurate if the rear-end platform always compares the information based on the first face information with the lowest pixel requirement.

In this embodiment, after the verification component acquires the second face image, a face pitch angle, a face deflection angle and an eye distance of the second face image are determined, where the face pitch angle, the face deflection angle and the eye distance are determined based on camera coordinates inside the camera.

And determining the influence weights (which can be prestored) of the face pitch angle, the face deflection angle and the eye distance on the face image quality score.

And determining a second quality score of the second face image based on the face pitch angle, the face deflection angle and the eye distance of the second face image and the corresponding influence weight.

And determining a third quality score of the third face image in the same manner of obtaining the second quality score.

As one example, the verification component further determines a first quality score for the first facial image in a manner to derive a second quality score.

As one example, the verification component directly receives a first quality score of a first facial image sent by the backend platform.

As an example, a target (highest) quality score is selected from the first quality score, the second quality score and the first quality score;

and sending the face information corresponding to the target (highest) quality score to the back-end platform so that the back-end platform can update the corresponding face information in the epidemic prevention data.

In this embodiment, the face information corresponding to the target quality score is further sent to the backend platform, so that the backend platform updates the face information corresponding to the epidemic prevention data. The comparison accuracy of the subsequent face verification for too long is improved.

Further, based on the first embodiment, the second embodiment, the third embodiment, and the fourth embodiment in the present application, in this embodiment, a local epidemic prevention database is set in the verification component, second epidemic prevention data of the local user is stored in the local epidemic prevention database, and the second epidemic prevention data includes fifth face information of the local user, and the method further includes:

step D1, if the touch operation to the face recognition button is detected, acquiring fourth face information of the second user;

step D2, comparing the fourth face information with the fifth face information in a one-to-many manner;

step D3, if the similarity between the fourth face information and the fifth face information is greater than or equal to a third preset threshold, determining that the face epidemic prevention verification of the second user is successful;

and D4, determining whether to issue an opening instruction to the access control equipment based on the second epidemic prevention data.

In this embodiment, the application scenarios targeted are:

for the staff who frequently gets into the entrance guard scene, like doctors in the hospital, nurses etc., all have the access guard of business turn over every day, carry out one-to-one with second people's face information and first people's face information and compare, verify too slowly, and can too much consume manpower and materials resource.

In this embodiment, a local epidemic prevention database is arranged in the verification component, second epidemic prevention data of a local user (local staff) is stored in the local epidemic prevention database, and the second epidemic prevention data includes fifth face information of the local user.

In this embodiment, the fourth face information and the fifth face information are subjected to one-to-many comparison, where the one-to-many comparison refers to: comparing a fourth face image acquired on site with all fifth face images in a local epidemic prevention database to obtain a face with the maximum matching similarity (if the similarity between the fourth face information and the fifth face information is greater than or equal to a third preset threshold value and the face with the maximum matching similarity is selected), determining that the second user face epidemic prevention verification is successful (an authentication mode for acquiring the identity of a person).

In this embodiment, for the staff who frequently gets into the entrance guard scene, the epidemic prevention data based on the local storage of verification subassembly is verified, promotes verification speed.
