Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification without any inventive step should fall within the scope of protection of the present specification.

As shown in fig. 1, an implementation subject of the method may be a biometric server, where the biometric server may be an independent server or a server cluster composed of a plurality of servers, and the biometric server may be configured to determine whether interaction data matches preset prompting information based on biometric video information, human-computer interaction information, and preset prompting information, and then perform biometric recognition processing on the user based on a matching result of the interaction data and the preset prompting information. The method may specifically comprise the steps of:

in step S102, receiving biometric video data acquired during biometric identification, which is uploaded by a terminal device, where the biometric video data includes biometric video information and human-computer interaction information, the human-computer interaction information includes interaction data generated by a user performing an interaction operation with a touch interface displayed by the terminal device during biometric identification, and the preset prompt information is used to instruct the user to be identified to perform a preset touch interaction operation.

The biometric information may be biometric information including iris features, or may be biometric information including facial features, which is not specifically limited in the embodiments of the present specification. The human-computer interaction information may include interaction operation information executed by the user based on preset prompt information (such as information of opening the mouth, blinking eyes, raising the head, shaking the head, and the like) in the process of biometric feature recognition. Or, the human-computer interaction information may further include interaction operation information executed by the user based on preset prompt information (e.g., pressing a preset key on the touch interaction interface) during the biometric feature recognition. Or dragging a preset icon displayed on the touch interactive interface from one position to interactive operation information executed at a preset position based on preset prompt information. Or, the above-mentioned human-computer interaction information may also include interaction operation information executed by the user based on preset prompting information (such as preset gesture operation) in the process of performing biometric feature recognition. The examples in this specification are not particularly limited thereto.

In practice, the security problem of biometric identification has been an important research topic in the industry, and since biometric identification (such as face identification) has been gradually popularized in life and production of people, the security problem of face identification is also more and more related to information and property security of people. However, an injection attack that a hacker acquires a biometric feature of a user by attacking a front camera of a terminal device, directly replaces an image acquired by the camera with an attack image, and then inputs the replaced attack image to the biometric feature recognition system has recently appeared. Aiming at the attack mode, the existing detection method is difficult to identify, so that serious potential safety hazards are brought to the information and property safety of people. For this reason, it is necessary to provide a technical solution capable of improving the security of biometric identification, and the following contents may be specifically mentioned.

In some optional implementation modes, a component for performing biometric identification and a camera component for shooting are installed in the terminal device of the user. If the user needs to perform biological feature identification when entering a certain application program, the user can trigger a biological feature identification key displayed by the terminal equipment, so that the terminal equipment can call the biological feature identification component after receiving the biological feature identification key triggered by the user, and start the camera shooting component to identify the biological feature to be identified of the user. As an example, taking the preset prompting information as dragging the preset icon displayed on the touch interactive interface from one position to a preset position as an example, after the terminal device receives a biological feature identification key triggered by a user, the camera assembly may be started to shoot a biological feature of the user to be identified, and simultaneously, the preset prompting information, and a preset image and preset position information corresponding to the preset prompting information may be displayed on the touch interactive interface, and the user may drag the preset icon displayed on the touch interactive interface from one position to a preset position based on the preset prompting information, so that the terminal device may obtain the biological feature video information and the human-computer interaction information, and send the obtained biological feature video information and the obtained human-computer interaction information as biological feature video data to the server, the server can receive the biological characteristic video data which are uploaded by the terminal equipment and acquired in the biological characteristic identification process.

In step S104, it is determined whether the interactive data matches the preset prompt information based on the biometric video information, the human-computer interaction information, and the preset prompt information.

In some optional implementation manners, taking the biological feature as a facial feature as an example, if the preset prompting message is to execute shaking the head left at a preset time, whether there is interactive data shaking the head left at the preset time in the interactive data may be determined based on the biological feature video information, the human-computer interaction information, and the preset prompting message. Or, for example, when the biometric feature is a facial feature, if the preset prompting message is that a preset icon displayed on the touch interactive interface is dragged from a position to a preset position at a preset time, it may be determined whether there is interactive data dragging the preset icon displayed on the touch interactive interface from a position to a preset position at the preset time in the interactive data based on the biometric video information, the human-computer interactive information, and the preset prompting message.

In step S106, biometric recognition processing is performed on the user based on the matching result of the interactive data and the preset prompt information.

In some alternative implementations, as an example in step S104, if it is determined whether there is interactive data shaking the head to the left at the preset time in the interactive data based on the matching result between the interactive data and preset prompting information, it may be determined that the biometric recognition is passed. Or, if it is determined that there is interactive data dragging a preset icon displayed on a touch interactive interface from one position to a preset position at the preset time in the interactive data based on a matching result of the interactive data and preset prompt information, it may be determined that the biometric identification is passed.

As can be seen from the technical solutions provided in the embodiments of the present specification, the biometric video data acquired during the biometric identification process uploaded by the terminal device is received, wherein the biometric video data includes biometric video information and human-computer interaction information, then, based on the biometric video information, the human-computer interaction information and the preset prompting information, whether the interaction data matches the preset prompting information is determined, and then, the biometric identification process is performed on the user based on the matching result of the interaction data and the preset prompting information, because the biometric video data acquired during the biometric identification process on the user includes the human-computer interaction data, the risk of video injection attack during the biometric identification process can be effectively avoided by performing the identification process on the acquired human-computer interaction data, thereby effectively improving the safety of the biological characteristic identification.

Further, the above-mentioned biometrics includes: one or more of facial features and iris features.

Further, the biometric features include facial features, as shown in fig. 2, before the step S104, the method may further include the following processing procedures of steps S108 to S110, and specifically, the following specific processing procedures of steps S108 to S110 may be referred to.

The document image data may be document image data including a face image of a user to be recognized, and the document image data may be resident identification card image data, resident social security card image data, military officer document image data, or the like, for example, and the document image data is not particularly limited by the embodiment of the present specification.

In some optional implementation manners, after the terminal device collects the biometric video data, or before the terminal device collects the biometric video data, after a biometric identification key triggered by a user is received, a camera component of the terminal device may be called to shoot the certificate image to obtain the certificate image data, and the certificate image data is uploaded to the server, so that the server may receive the certificate image data of the user to be identified, which is uploaded by the terminal device.

In step S110, it is determined whether or not the facial feature image contained in the document image data of the user to be identified matches the facial feature image contained in the biometrics video information.

In some optional implementation manners, a preset image matching algorithm may be used to match the facial feature image included in the certificate image data of the user to be identified and the facial feature image information included in the biometric video information, and determine whether the facial feature image included in the certificate image data of the user to be identified matches the facial feature image information included in the biometric video information.

The processing method of step S104 may be various, and an alternative processing method is provided below, which may be specifically referred to as the specific processing procedure of step S1042 below.

And if the facial feature image contained in the certificate image data of the user to be identified is matched with the facial feature image contained in the biological feature video information, judging whether the interactive data is matched with the preset prompt information or not based on the biological feature video information, the human-computer interaction information and the preset prompt information.

In some optional implementation manners, if it is determined through the above process that the facial feature image included in the certificate image data of the user to be identified does not match the facial feature image information included in the biometric video information, it may be determined that the user to be identified is an illegal user, and a result of biometric identification failure may be sent to the terminal device. If the face characteristic image contained in the certificate image data of the user to be identified is judged to be matched with the face characteristic image information contained in the biological characteristic video information through the process, the user to be identified can be confirmed to be the certificate holder, and whether the interactive data is matched with the preset prompt information or not can be judged based on the biological characteristic video information, the human-computer interaction information and the preset prompt information.

Further, as shown in fig. 3, the processing method of step S106 may be various, and an alternative processing method is provided below, which may specifically refer to the specific processing procedure of step S1062-step S1064.

In step S1062, if the interactive data matches the preset prompting information, it is determined whether a feature point corresponding to a preset facial feature in the biometric video information changes within a preset time period.

The preset biological characteristics can be one or more of eye characteristics, lip characteristics and cheeks, and the eye characteristics can include eyeball characteristics. The feature point may be a point constituting the preset biometric feature in an image frame corresponding to a preset time.

In some optional implementation manners, taking the preset biological features as an eyelid and an eyeball as an example, a preset number of image frames may be taken from the biological feature video information acquired within a preset time period, and whether there is a difference between feature points corresponding to any two image frames and constituting the eyeball feature is determined, that is, whether there is a rhythm in the eyeball feature within the preset time period is determined. Taking the preset biological feature as the cheek as an example, any preset number of image frames may be taken from the biological feature video information acquired in a preset time period, and whether there is a difference between feature points corresponding to any two image frames and constituting the cheek feature is determined, that is, whether there is stretching of the cheek feature in the preset time period is determined.

In step S1064, biometric feature recognition processing is performed on the user according to a situation that the feature point corresponding to the preset facial feature changes within a preset time period.

In some optional implementations, as an example of the step S1064, if the feature point corresponding to the preset biometric feature changes within the preset time period, it may be determined that the biometric feature is a living feature, and the biometric feature identification process is not subject to common attacks such as copying, printing, or masking. Thus, through the above processing procedure, common attacks such as copying, printing or masks can be effectively avoided, thereby further providing the security of the above biometric identification process.

In some alternative implementations, the above processes of step S1062 and step S1064 may be implemented by a pre-trained model, namely, the biological characteristic video information including the biological characteristic video information of the preset time period or the biological characteristic video information can be input into a silence living body detection model trained in advance, so as to perform silence and live body detection on the biological characteristic video information to judge whether the characteristic points corresponding to the preset facial characteristics in the biological characteristic video information change in a preset time period, if the feature point corresponding to the preset biological feature changes in a preset time period, the biological feature video information is determined to pass the silent live body detection, at this time, the biometric identification processing may be continued in another manner, or it may be directly determined that the biometric identification is passed this time.
