In recent years, technical research based on artificial intelligence, such as computer vision, deep learning, machine learning, image processing, and image recognition, has been advanced significantly. Artificial Intelligence (AI) is an emerging scientific technology for studying and developing theories, methods, techniques and application systems for simulating and extending human Intelligence. The artificial intelligence subject is a comprehensive subject and relates to various technical categories such as chips, big data, cloud computing, internet of things, distributed storage, deep learning, machine learning and neural networks. Computer vision is an important branch of artificial intelligence, particularly a machine is used for identifying the world, and computer vision technologies generally comprise technologies such as face identification, living body detection, fingerprint identification and anti-counterfeiting verification, biological feature identification, face detection, pedestrian detection, target detection, pedestrian identification, image processing, image identification, image semantic understanding, image retrieval, character identification, video processing, video content identification, three-dimensional reconstruction, virtual reality, augmented reality, synchronous positioning and map construction (SLAM), computational photography, robot navigation and positioning and the like. With the research and progress of artificial intelligence technology, the technology is applied to many fields, such as safety control, city management, traffic management, building management, park management, face passage, face attendance, logistics management, warehouse management, robots, intelligent marketing, computational photography, mobile phone images, cloud services, smart homes, wearable equipment, unmanned driving, automatic driving, intelligent medical treatment, face payment, face unlocking, fingerprint unlocking, person certificate verification, smart screens, smart televisions, cameras, mobile internet, live webcasts, beauty treatment, medical beauty treatment, intelligent temperature measurement and the like.
Among them, the biometric technology has been widely applied to various terminal devices or electronic apparatuses. Biometric identification techniques include, but are not limited to, fingerprint identification, palm print identification, vein identification, iris identification, face identification, biometric identification, anti-counterfeiting identification, and the like. Among them, fingerprint recognition generally includes optical fingerprint recognition, capacitive fingerprint recognition, and ultrasonic fingerprint recognition. With the rise of the full screen technology, the fingerprint identification module can be arranged in a local area or a whole area below the display screen, so that Under-screen (Under-display) optical fingerprint identification is formed; or, the optical fingerprint identification module can be partially or completely integrated into the display screen of the electronic device, so that In-screen (In-display) optical fingerprint identification is formed. The Display screen may be an Organic Light Emitting Diode (OLED) Display screen, a Liquid Crystal Display (LCD), or the like. Fingerprint identification methods generally include the steps of fingerprint image acquisition, preprocessing, feature extraction, feature matching, and the like. Part or all of the steps can be realized by a traditional Computer Vision (CV) algorithm, and also can be realized by an Artificial Intelligence (AI) -based deep learning algorithm. The fingerprint identification technology can be applied to portable or mobile terminals such as smart phones, tablet computers and game equipment, and other electronic equipment such as smart door locks, automobiles and bank automatic teller machines, and is used for fingerprint unlocking, fingerprint payment, fingerprint attendance, identity authentication and the like.
At present, in a place such as a community or a company where identity authentication of an visitor is required, a panel machine is generally installed at a doorway, biometric recognition (e.g., face recognition) is performed on the visitor by the panel machine, and the identity of the visitor is authenticated based on a biometric recognition result (e.g., face recognition result). However, the height of the panel machine is usually about 1.5 m, and the identification part (for example, the face) of a part of special people (for example, the short people such as children) can not enter the identification range of the panel machine, so that the panel machine is inconvenient for the special people to use. If a two-dimensional code identification module or a card swiping identification module is added to the panel machine, not only are greater potential safety hazards caused by the conditions of two-dimensional code leakage, card loss and the like, but also the cost of the panel machine is increased due to more modules. The application provides an identity authentication method which can improve the safety of identity authentication aiming at special crowds and reduce the cost of a panel machine.
Referring to fig. 1, a schematic diagram of an identity authentication system according to the present application is shown. The identity authentication system may include a panel machine (as shown at reference numeral 101) and a storage medium (as shown at reference numeral 102). The panel machine may be configured with an interface for accessing the storage medium. The panel machine may be a panel machine for performing biometric identification, and may further include a camera, a processor, a memory, and other components, which are not limited herein. The storage medium may be a carrier for storing data, and may include, but is not limited to, at least one of the following: a Universal Serial Bus Flash Disk (usb Flash Disk), a Compact Flash (CF) Card, a Secure Digital (SD) Card, an MMC (Multi-Media Card), a Smart Media (SM) Card, a Secure Digital High Capacity (SD) Card, and the like.
In this embodiment, the panel machine may be configured to, when it is detected that the storage medium accesses the interface, query, from the storage medium, a target file whose file name satisfies a target condition. Wherein the object file comprises at least one of: image files, video files. And if the target file is inquired, extracting the biological characteristics of the object in the target file, and authenticating the identity of the object based on the biological characteristics.
Here, the panel machine can detect whether the storage medium is accessed to the interface in real time. A system broadcast may be triggered when the storage medium accesses the interface. The panel computer can determine the storage medium access interface when receiving the system broadcast. Taking the storage medium as a USB disk as an example, when the USB disk is inserted into an interface (e.g., USB interface) of the panel computer, a system broadcast (e.g., USB _ DEVICE _ authenticated) is triggered, and when the processor of the panel computer receives the system broadcast, the USB disk access interface may be determined.
The target conditions may include, but are not limited to: the file name comprises a target character string, and the target character string is located at the target position of the file name. If the file name contains the object string "self", and the object string "self" is the head end of the file name, such as "self _20220530_20220630", the file is considered to be the object file. Note that when the file name is "self", it can also be a target file. Therefore, the user can directly name the recorded target file in a naming mode meeting the target condition and then store the named target file in the storage medium, and the named target file can be inquired and analyzed by the panel computer, so that the convenience of inquiring the target file is improved.
The above-mentioned biometric features may include, but are not limited to, at least one of: face features, iris features, fingerprint features, and palm print features. After the biometric features are extracted, the biometric features may be matched with the pre-stored biometric features (for example, similarity is calculated by using a similarity calculation method such as euclidean distance), and if there are pre-stored biometric features that match the extracted biometric features (for example, the similarity is greater than a threshold), the identity authentication of the object may be considered to be passed. Otherwise, the identity authentication of the object is considered to be failed.
The pre-stored biological characteristics can be stored in the panel machine locally or in the server. When the pre-stored biological characteristics are stored in the server, the extracted biological characteristics can be sent to the server in a wired connection or wireless connection mode, and an identity authentication result returned by the server is received. The wireless connection means may include, but is not limited to, a 3G (3 rd-Generation, third Generation mobile communication technology) connection, a 4G (4 rd-Generation, fourth Generation mobile communication technology) connection, a 5G (5 rd-Generation, fifth Generation mobile communication technology), a Wi-Fi (wireless network communication technology) connection, a bluetooth connection, a WiMAX (World Interoperability for Microwave Access) connection, a Zigbee (Zigbee protocol) connection, a UWB (ultra wideband) connection, and other wireless connection means now known or developed in the future.
In the system provided by the above embodiment of the present application, when the panel machine detects that the storage medium is accessed to the interface configured thereon and used for accessing the storage medium, the target file with the file name satisfying the target condition in the storage medium is queried, and when the target file is queried, the biometric feature of the object in the target file is extracted, so that the identity authentication of the object can be performed based on the extracted biometric feature. Therefore, special crowds (such as children and other shorter crowds) can directly name the recorded target file in a naming mode meeting the target condition and then store the named target file in the storage medium, the storage medium is connected to an interface of the panel computer, and identification can be successfully achieved without enabling the identification part (such as the face) to enter the identification range of the panel computer. Compared with the modes of scanning two-dimensional codes or swiping cards and the like, the biological characteristics are not easy to acquire and analyze by others, so that the identity authentication for special people is safer. Simultaneously, need not set up other modules for the panel machine, reduced panel machine cost.
In some alternative embodiments, the panel machine may be further configured to: if the target file is inquired, determining the effective time period of the target file based on the name of the target file; and if the current time is in the effective time period, extracting the biological characteristics of the object in the target file, and performing identity authentication on the object based on the biological characteristics.
As an example, the start time and the end time of the validity period may be included in the file name of the target file. For example, the naming format of the object file may be self _ start _ end, where "start" represents the start time of the valid period (i.e. the start time of the user's right to pass) and "end" represents the end time of the valid period (i.e. the end time of the user's right to pass). If the file name of the target file is "self _20220530_20220630", it indicates that the valid period of the target file is from 30/5/2022 to 30/6/2022. If the file name of the target file is "self", it can be indicated that the target file is permanently valid. If the target file is inquired, the panel machine can firstly determine the effective time period of the target file based on the name of the target file. If the current time is within the valid time period, the step of extracting the biometric characteristic of the object in the target file may be performed. If the current time interval is not in the valid time interval, prompt information for prompting that the user has no passing authority can be displayed, or any operation can not be executed.
By setting the start time and the end time of the valid period in the file name of the target file, the target file can be made to have the valid period. When the target file fails, it cannot be parsed. Therefore, the safety of the target file is improved.
In some alternative embodiments, the operation modes of the panel machine may include, but are not limited to, a liveness detection mode and a biometric recognition mode. The panel machine may default to a live body detection mode to perform live body detection on an object within the identification range. After the living body detection is passed, the system can be switched to a biological feature recognition mode to perform biological feature recognition (such as human face recognition). After the biometric identification is finished, the mode can be switched to the live body detection mode again so as to perform the live body detection on the next visitor. In this embodiment, the panel computer may perform query of the target file when detecting the storage medium access interface, and may switch the operation mode from the living body detection mode to the biometric identification mode when querying the target file, so that biometric extraction may be directly performed on the object in the target file without performing living body detection. Therefore, special crowds (such as shorter crowds like children) can directly name the recorded target file in a naming mode meeting target conditions and then store the named target file in the storage medium, the storage medium is connected to an interface of the panel computer, identification parts (such as faces) do not need to enter an identification range of the panel computer, identity authentication can be successfully achieved, and flexibility and convenience of identity authentication of the special crowds are improved.
In some alternative embodiments, the target file may be a video file. When the panel machine extracts the biological characteristics of the object in the target file, the panel machine can firstly unpack the target file to obtain the code stream in the target digital video compression format. The codestream may then be decoded into a sequence of video frames in the target color-coded format. Finally, the biometric features of the video frames in the sequence of video frames may be extracted. The target digital video compression format may include, but is not limited to, an h.264 digital video compression format. The target color coding format may include, but is not limited to, YUV (Y represents luminance, U and V may represent chrominance, where U represents chrominance for the blue component and V represents chrominance for the red component) color coding format. In practice, decoding of the code stream can be performed by a decoder such as MediaCodec. On the basis, the biological features extracted from each video frame can be respectively compared with the pre-stored biological features, and if the similarity between the biological features extracted from a certain video frame and a certain pre-stored biological feature is greater than a preset value, the identity authentication of the object can be determined to be passed. Otherwise, it is determined that the identity authentication of the object is not passed. Since the video comprises more frames compared with the image, the accuracy of the identity authentication result can be improved.
Further, since more additional information, such as audio data, location, video generation date, etc., can be stored in the video file, the panel machine can also perform identity authentication in combination with the additional information. As an example, voiceprint features can be extracted from audio data while identity authentication is performed based on biometric features and voiceprint features. Therefore, the accuracy of the identity authentication result can be further improved.
In some optional embodiments, the identity authentication system may further include a door access device (as indicated by reference numeral 104 in fig. 1). The panel machine may also be used to: and if the identity authentication of the object passes, the access control equipment can be controlled to be opened. If the identity authentication of the object is not passed, prompt information can be output. The prompt message can be used for prompting the user that the user has no right of passage. The output mode of the prompt message may include but is not limited to: displaying on a screen of the panel machine, broadcasting by voice of the panel machine, and the like.
In some alternative embodiments, the storage medium may comprise a USB flash drive (i.e., a USB flash drive). The interface may comprise a USB interface. The panel machine can be configured with a USB extension cord, and the storage medium can be accessed into the interface through the USB extension cord. Referring to fig. 1, a panel machine (as shown by reference numeral 101) may be provided at a gate of a doorway of a community. The panel machine may be configured with a USB interface. The USB interface is connected to a USB extension cord (indicated by reference numeral 103). The user can insert the USB extension line with the USB flash disk, realizes the USB flash disk and inserts. Therefore, special crowds (for example, shorter crowds such as children) can plug and pull the USB flash disk conveniently, and the convenience of operation of the crowds is improved.
In some alternative embodiments, the file name may not include an extension. When extracting the biological features of the object in the target file, the extension name may be added first, and then the biological features may be extracted. Therefore, any user cannot directly view the file content, and the safety of the target file and the safety of identity authentication are further improved.
With continued reference to FIG. 2, a flow 200 of one embodiment of an identity authentication method according to the present application is shown. The identity authentication method can be applied to a panel machine, and the panel machine is provided with an interface for accessing a storage medium. The identity authentication method comprises the following steps:
In this embodiment, an executing entity (for example, a processor in the panel machine) of the identity authentication method may detect whether the storage medium is accessed to the interface. For example, a system broadcast may be triggered when the storage medium accesses the interface. The execution agent may determine the storage medium access interface upon receiving the system broadcast. Taking the storage medium as a USB disk as an example, when the USB disk is inserted into an interface (e.g., USB interface) of the panel computer, a system broadcast (e.g., USB _ DEVICE _ authenticated) is triggered, and when the processor of the panel computer receives the system broadcast, the USB disk access interface may be determined.
When the storage medium access interface is detected, the execution subject can inquire a target file with a file name meeting a target condition in the storage medium. Wherein the object file comprises at least one of: image files, video files. Target conditions may include, but are not limited to: the file name comprises a target character string, and the target character string is located at the target position of the file name. For example, if the file name includes a target character string "self", and the target character string "self" is the head end of the file name, such as "self _20220530_20220630", the file can be considered as a target file. Note that when the file name is "self", it can also be a target file. Therefore, the user can directly name the recorded target file in a naming mode meeting the target condition and then store the named target file in the storage medium, and the named target file can be inquired and analyzed by the panel computer, so that the convenience of inquiring the target file is improved.
In this embodiment, if the target file is queried from the storage medium, the biometric features of the object in the target file can be extracted. The above-mentioned biometric features may include, but are not limited to, at least one of: face features, iris features, fingerprint features, and palm print features. After the biometric features are extracted, the biometric features may be matched with pre-stored biometric features (for example, similarity is calculated by using a similarity calculation method such as euclidean distance), and if there are pre-stored biometric features that match the extracted biometric features (for example, the similarity is greater than a threshold), the identity authentication of the object may be considered to be passed. Otherwise, the identity authentication of the object is considered to be not passed.
The pre-stored biological characteristics can be stored in the panel machine locally or in the server. When the pre-stored biological characteristics are stored in the server, the extracted biological characteristics can be sent to the server in a wired connection or wireless connection mode, and an identity authentication result returned by the server is received. The wireless connection may include, but is not limited to, a 3G (3 rd-Generation, third Generation mobile communication technology) connection, a 4G (4 rd-Generation, fourth Generation mobile communication technology) connection, a 5G (5 rd-Generation, fifth Generation mobile communication technology), a Wi-Fi (wireless network communication technology) connection, a bluetooth connection, a WiMAX (World Interoperability for Microwave Access) connection, a Zigbee (Zigbee protocol) connection, an UWB (ultra wide band) connection, and other wireless connection methods now known or developed in the future.
In the method provided by the above embodiment of the present application, when the panel machine detects that the storage medium is accessed to the interface configured thereon and used for accessing the storage medium, the target file with the file name satisfying the target condition in the storage medium is queried, and when the target file is queried, the biometric feature of the object in the target file is extracted, so that the identity authentication of the object can be performed based on the extracted biometric feature. Therefore, special crowds (such as short crowds like children) can directly name the recorded target file in a naming mode meeting the target condition and then store the named target file in the storage medium, the storage medium is connected to an interface of the panel computer, and identification can be successfully achieved without enabling the identification part (such as the face) to enter the identification range of the panel computer. Compared with the modes of scanning two-dimensional codes or swiping cards and the like, the biological characteristics are not easy to acquire and analyze by others, so that the identity authentication for special people is safer. Simultaneously, need not set up other modules for the panel machine, reduced panel machine cost.
In some alternative embodiments, the start time and the end time of the validity period may be included in the filename of the target file. For example, the naming format of the object file may be self _ start _ end, where "start" represents the start time of the valid period (i.e. the start time of the user's right to pass) and "end" represents the end time of the valid period (i.e. the end time of the user's right to pass). If the file name of the target file is "self _20220530_20220630", it indicates that the valid period of the target file is from 30/5/2022 to 30/6/2022. Note that, if the file name of the target file is "self", it can be indicated that the target file is permanently valid.
On the basis, in step 202, if the target file is queried, the execution body may first determine a valid period of the target file based on the name of the target file. If the current time is within the valid period, the step of extracting the biometric characteristic of the object in the target file may be performed. If the current time interval is not in the valid time interval, prompt information for prompting that the user has no passing authority can be displayed, or any operation can not be executed.
By setting the start time and the end time of the valid period in the file name of the target file, the target file can be made to have the valid period. When the target file fails, the target file cannot be parsed. Therefore, the safety of the target file is improved.
In some alternative embodiments, the operation modes of the panel machine may include, but are not limited to, a liveness detection mode and a biometric recognition mode. The panel machine may default to a live detection mode to perform live detection on objects within the identification range. After the living body detection is passed, the living body detection device can be switched to a biological feature recognition mode to perform biological feature recognition (such as human face recognition). After the biometric identification is finished, the mode can be switched to the live body detection mode again so as to perform the live body detection on the next visitor. In this embodiment, when the storage medium access interface is detected, the target file is queried, and when the target file is queried, the working mode can be switched from the living body detection mode to the biological feature recognition mode, so that the biological feature extraction of the object in the target file is directly performed without performing the living body detection. Therefore, special crowds (for example, children and other shorter crowds) can directly name the recorded target file in a naming mode meeting the target condition and then store the named target file in the storage medium, the storage medium is connected to an interface of the panel computer, identification can be successfully achieved without enabling an identification part (for example, the face) to enter an identification range of the panel computer, and flexibility and convenience of identification of the special crowds are improved.
In some alternative embodiments, the target file may be a video file. When extracting the biological characteristics of the object in the target file, the target file can be unpacked first to obtain the code stream in the target digital video compression format. The codestream may then be decoded into a sequence of video frames in the target color-coded format. Finally, the biometric features of the video frames in the sequence of video frames may be extracted. The target digital video compression format may include, but is not limited to, an h.264 digital video compression format. The target color coding format may include, but is not limited to, YUV (Y represents luminance, U and V may represent chrominance, where U represents chrominance for the blue component and V represents chrominance for the red component) color coding format. In practice, decoding of the code stream can be performed by a decoder such as MediaCodec. On the basis, the biological features extracted from each video frame can be respectively compared with the pre-stored biological features, and if the similarity between the biological features extracted from a certain video frame and a certain pre-stored biological feature is greater than a preset value, the identity authentication of the object can be determined to be passed. Otherwise, it is determined that the identity authentication of the object fails. Since the video comprises more frames relative to the image, the accuracy of the identity authentication result can be improved.
Further, since more additional information, such as audio data, location, video generation date, etc., can be stored in the video file, the identification can be performed in combination with the additional information. As an example, voiceprint features can be extracted from audio data while identity authentication is performed based on biometric features and voiceprint features. Therefore, the accuracy of the identity authentication result can be further improved.
In some optional embodiments, if the identity authentication of the object passes, the access control device may be controlled to open. Wherein the access control device may include, but is not limited to, at least one of: door and lock. If the identity authentication of the object is not passed, prompt information can be output. The prompt message can be used for prompting the user that the user has no right of passage.
In some alternative embodiments, the storage medium may comprise a USB flash drive (i.e., a USB flash drive). The interface may comprise a USB interface. The panel machine can be configured with a USB extension cord, and the storage medium can be accessed into the interface through the USB extension cord. The user can insert the USB extension line with the USB flash disk, realizes the USB flash disk and inserts. Therefore, special crowds (such as shorter crowds like children) can plug and pull the USB flash disk conveniently, and the convenience of the operation of the crowds is improved.
In some alternative embodiments, the file name may not include an extension. When extracting the biological features of the object in the target file, the extension name may be added first, and then the biological features may be extracted. Therefore, any user cannot directly view the file content, and the safety of the target file and the safety of identity authentication are further improved.
