In step S204, a set of biometric information matching a set of card numbers recognized by the access control device from within the recognition range of the access control device is obtained, wherein the detection range of the biometric detection device at least partially overlaps with the recognition range of the access control device.
The access control device may be provided with a card number identification module, configured to identify a card number (e.g., employee card information) existing within an identification range of the access control device, obtain a set of card numbers, and send the identified card number to the server. The set of card numbers may include one or more card numbers, may include the latest card number recognized by the access control device before the current time, and may also include card numbers recognized within a period of time before the current time. In order to facilitate the biometric information collection and the card number identification of the user, the detection range of the biometric detection device and the identification range of the entrance guard device may at least partially overlap. The same person can simultaneously perform card number identification and biometric information detection at the same position.
For a group of card numbers identified by the access control device, a group of biological characteristic information matched with the group of card numbers can be obtained, the card numbers of the group of card numbers and the biological characteristic information in the group of biological characteristic information can be in one-to-one correspondence or not, and one card number can correspond to one biological characteristic information or a plurality of different types of biological characteristic information.
A set of biometric information matching a set of card numbers identified by the access control device may be obtained by the access control device or the server. In the case where the server performs the acquisition of the set of biometric information matching the set of card numbers, the access control device may transmit the set of card numbers to the server, and the server may extract the set of biometric information from the biometric database.
Optionally, in this embodiment, the obtaining of a set of biometric information that matches a set of card numbers that are recognized by the access control device from within the recognition range of the access control device includes: receiving a group of card numbers which are sent by an Internet of things platform and are recognized by the access control equipment from the recognition range of the access control equipment; and extracting a group of biological characteristic information matched with the group of card numbers from a biological characteristic database, wherein the biological characteristic database stores the recorded biological characteristic information corresponding to the pre-stored card number, the pre-stored card number is a card number which allows the access control equipment to open a door controlled by the access control equipment, and the pre-stored card number comprises the group of card numbers.
The access control device can send a group of card numbers identified from the identification range to the Internet of things platform, and the Internet of things platform sends the group of card numbers to the server. The server stores a biological characteristic database, and after a group of card numbers sent by the internet of things platform are received, biological characteristic information matched with each card number in the group of card numbers can be sequentially acquired to obtain a group of biological characteristic information.
The person feature information may be warehoused by biometric (e.g., face feature) registration to store a correspondence of the person information (which may include a card number) and the person feature information (which may include biometric information) in a biometric database of a server (e.g., a face recognition server).
For example, as shown in fig. 4, the door access system includes: the system comprises access control equipment, an internet of things platform and a face recognition server, wherein the function of data transmission in the directions of the access control equipment, the internet of things platform and the face recognition server is to generate a comparison database, and the function of data transmission in the directions of the face recognition server, the internet of things platform and the access control equipment is to transmit back a comparison result.
The RFID identification module of the access control equipment transmits the identified personnel information to the face recognition server through the Internet of things platform, and the face recognition server reads the face information corresponding to the personnel information to generate a comparison database. The face recognition module of the access control equipment sends the collected face information to the face recognition server in real time, the face recognition server matches the real-time face information with the face information in the comparison database, and the matching result is sent to the access control equipment through the internet of things platform or other modes.
By the embodiment, the characteristic comparison database (biological characteristic database, a group of biological characteristic information) is placed on the server instead of the internet of things platform, so that the time for storing and transmitting data can be saved, and meanwhile, the real-time biological characteristic detection device (e.g. face acquisition device) directly accesses the server (e.g. face recognition server), so that the transmission time can be reduced, and the efficiency can be improved.
The card number identified by the access control device may be used to represent a target object, which may be a person, that allows the access control device to open a door controlled by the access control device. The card number may include, but is not limited to, at least one of: the id of the person, work card number, or other type of card number that can be used to represent the target object.
Optionally, in this embodiment, before receiving a set of card numbers, which are sent by the internet of things platform and recognized by the access control device from the identification range of the access control device, a set of radio frequency tag information, which is recognized by the access control device and is located in the identification range, is obtained through the internet of things platform, so as to obtain the set of card numbers.
The card number may be included in the identity information of the specific object, and may be a card number (e.g., RFID) of a worker card, and the worker card may include a worker card chip, and the card number is written to the worker card chip. The access control equipment can be provided with an intelligent chip for reading the identity information of people in a certain range nearby. The card number that can be recognized by the access control device may be a card number that allows the access control device to open a door controlled by the access control device, and the card number that cannot be recognized by the access control device may be a card number that does not allow the access control device to open a door controlled by the access control device.
The access control device can identify radio frequency tag information (RFID) within its identification range, and send the identified RFID information to the server through the internet of things platform (as shown in fig. 4). The access control device may send the radio frequency tag information in various ways, for example, the access control device may send the currently identified radio frequency tag information to the server, or may send the radio frequency tag information identified within a period of time before the current time to the server in a unified manner.
Through the embodiment, the card number information is carried in the radio frequency tag mode, and the convenience and the safety of card number identification can be guaranteed.
After a set of card numbers identified by the access control device is acquired, the set of biometric information can be matched by using the set of card numbers. Since the server stores the correspondence between the card number and the biometric information, the biometric information corresponding to each card number can be acquired by card number matching.
Alternatively, in the case where one card number corresponds to a plurality of types of biometric information, biometric information of the same type as the first biometric information may be acquired according to the type of the first biometric information.
For example, biometric information corresponding to a card number includes: face, iris, fingerprint, and palm print. The first biometric information detected by the biometric detection device includes: face and fingerprint, the biometric information corresponding to each card number that is obtained includes: human faces and fingerprints.
After a group of biological characteristic information matched with the group of card numbers is obtained, the first biological characteristic information is compared with the group of biological characteristic information in a characteristic mode, and the biological characteristic information matched with the first biological characteristic information exists in the group of biological characteristic information.
There are various ways to perform the feature comparison between the first biometric information and the set of biometric information, for example, the matching degree between the first biometric information and each biometric information in the set of biometric information can be determined.
Optionally, in this embodiment, before the access control device is controlled to open the door controlled by the access control device, feature similarities between the first biometric information and each biometric information in the set of biometric information are sequentially determined; and determining that the biological characteristic information matched with the first biological characteristic information exists in the group of biological characteristic information under the condition that the characteristic similarity of the first biological characteristic information and the second biological characteristic information in the group of biological characteristic information is greater than or equal to the target similarity.
Due to the influence of environmental factors, parameters of the device and the like, the biological characteristic information acquired by the same device or different devices at the same time or different times is not completely the same. Therefore, it is possible to set a feature parameter used for biometric matching, and set threshold information for matching, which may be a threshold of feature similarity between biometrics (target similarity).
According to the feature parameters used in the biometric matching, feature values of the first biometric information and each of the biometric information in the group of biometric information can be determined, and feature similarity between the first feature value corresponding to the first biometric information and each of the second feature values corresponding to each of the biometric information in the group of biometric information is calculated. In the case where the similarity between the first feature value and one of the second feature values is greater than or equal to a target similarity (similarity threshold), it is determined that there is biometric information matching the first biometric information in the set of biometric information.
For example, after the chip reads the personnel identity information, the face feature information of the part of people is extracted to be used as a matching database for face recognition, the feature value matching is carried out in the database by using a face recognition algorithm, and if the feature value exceeds a certain threshold value, the access control can be considered to be passed.
According to the embodiment, whether the biological characteristic information matched with the first biological characteristic information exists in the group of biological characteristic information is determined according to the characteristic similarity between the first biological characteristic information and each piece of biological characteristic information in the group of biological characteristic information, so that the influence of factors such as environment on the matching of the biological characteristic information can be avoided, and the accuracy of the biological characteristic matching is improved.
In step S206, in the case that there is second biometric information matching the first biometric information in the set of biometric information, the access control device is controlled to open a door controlled by the access control device.
And if second biological characteristic information matched with the first biological characteristic information exists in the group of biological characteristic information, determining that the entrance guard can be passed. The target object corresponding to the first biological characteristic information can be allowed to pass through the door controlled by the access control device in a mode of controlling the access control device to open the door controlled by the access control device.
The manner of controlling the access control device to open the door controlled by the access control device may be various, for example, in the case where the access control device performs access control alone, the door opening instruction may be transmitted through a data line (e.g., a data bus) inside the access control device to control opening of the door controlled by the access control device.
Optionally, in this embodiment, controlling the access control device to open the door controlled by the access control device includes: and sending a comparison result to the access control equipment through the Internet of things platform, wherein the comparison result is used for indicating the access control equipment to open a door controlled by the access control equipment.
The server can be used for comparing the first biological characteristic information with a group of biological characteristic information, and the comparison result is transmitted back to the access control equipment through the internet of things platform, so that the access control equipment can perform access control according to the comparison result.
The operations performed by the server may include: receiving and storing personnel registration information (including biological characteristic information corresponding to the card number) and generating a reference library; generating a comparison library according to a group of card number information identified by the access control equipment; and receiving the real-time biological characteristic information, comparing the real-time biological characteristic information with a comparison library, and returning a comparison result to the access control equipment.
For example, as shown in fig. 5, the face recognition server may be responsible for collecting face feature information, extracting a feature comparison database, receiving face real-time image information, and returning a face feature comparison result. The feature comparison database is not placed on the Internet of things platform, data storage and transmission are saved, meanwhile, the real-time face acquisition equipment directly accesses face recognition service, transmission time is shortened, and efficiency is improved.
Through this embodiment, give entrance guard's equipment with the comparison result passback by the server, by entrance guard's equipment according to the door that the comparison result control entrance guard's equipment controlled, can reduce the demand to the server, guarantee entrance guard's equipment ability of controlling to the door.
To improve efficiency, the matching feature database may be data of people in the vicinity of the access control system over a period of time, with fewer matches giving a faster match.
There are a number of ways to ensure that the matching feature database is card number information that is in the vicinity of the access system over a period of time.
As an alternative embodiment, in a predetermined time after the door controlled by the door control device is opened, in the case that the target card number matching the second biometric information in the set of card numbers is not recognized from the recognition range, the target card number is deleted from the set of card numbers, and the second biometric information is deleted from the set of biometric information.
The card number identified by the access control equipment can be stored by the access control equipment, and the card number which is not in the identification range of the access control equipment and is a period of time after passing through the access control equipment is deleted; the card number which is identified by the access control equipment and does not control the access control equipment to pass through the access control equipment can be deleted after a period of time so as to ensure that the latest card number information is stored in the access control equipment.
For example, if the face feature information acquired by the image acquisition device (a type of biometric detection device) matches with the face feature information of the person a (the work card number is the work card a), the access control is performed. And within 10s (the preset time is 10s, or longer or shorter preset time can be set according to needs) after the entrance guard passes through the entrance guard, if the worker card A is not identified in the identification range of the entrance guard equipment, determining that the worker A is not in the distance range, deleting the worker card A from the card number stored in the entrance guard equipment, and deleting the face feature information of the worker A from the comparison feature library.
If the card number is newly identified or deleted by the access control device (a group of card numbers stored by the access control device changes), the card number change information can be sent to the server through the Internet of things platform, and the server updates the group of biological characteristic information, so that the group of card numbers stored by the access control device is synchronized with the group of biological characteristic information in the server.
For the access control equipment, the access control equipment can be responsible for personnel information management and communication with the Internet of things platform. The personnel information management comprises: collecting personnel information within a certain distance nearby (which can be carried on a work card chip); and deleting the current personnel information within a period of time after passing the entrance guard. The communication performed by the access control device may include: the personnel information is transmitted to the Internet of things platform; and receiving a checking result of the Internet of things platform to determine whether the access control is passed.
For example, as shown in fig. 6, in the case that the access control device and the biometric detection device are the same device, the main function of the access control device is to complete the management of the personnel information and communicate with the internet of things platform to obtain the final verification result. The access control equipment can: the work card information in the distance range is identified; the system is responsible for deleting the information of the personnel who pass through the entrance guard within a period of time and are not within the distance range; the method is in charge of face real-time information acquisition, and the process of executing access control by access control equipment comprises the following steps:
and S1, the entrance guard equipment collects the worker card information.
And S2, judging whether the work card information is collected in the distance range of the access control equipment, if so, executing the step S3, otherwise, returning to execute the step S1.
And S3, acquiring the face image information, and sending the acquired image to a face recognition server for verification.
The collected image information may be face image information collected a period of time after the work card information is recognized.
S4, if the check is passed, executing the step S5, otherwise, ending.
If the collected face image information passes the verification, step S5 may be executed, otherwise, if none of the collected face image information passes the verification after a period of time (a first period of time, which may be set as required) after the work card information is identified, the process may be ended after the work card information is deleted.
And S5, judging whether the public information of the person is in the distance range of the access control equipment within a period of time after the person passes through the access control equipment, and if not, executing the step S6.
If the public information of the person is not within the distance range of the access control device within a period of time after the person passes through the access control (the second period of time may be set as required, and may be the same as or different from the first period of time), step S6 is executed, and if the public information of the person is within the distance range of the access control device within a period of time after the person passes through the access control, step S3 may be executed again, or a prompt message may be sent to prompt that the person passes the verification so as to prompt the person to enter a specific area as soon as possible, and then step S6 is executed.
And S6, deleting the personnel information within a period of time after passing the entrance guard, and ending.
