It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present specification. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the present disclosure.

eKYC is electronic identity authentication, namely, the process of automatically verifying user identity authentication is remotely completed by using an AI technology, so that the true identity of a user is known, the risk caused by identity fraud is reduced, and compared with the traditional offline KYC flow, the online authentication method is simpler and more efficient and has better user experience. In a typical eKYC process, a user is required to take a photograph of his Identity (ID) document (e.g., an identification card, driver's license, passport, etc.) as part of an authentication process to verify ownership factors (i.e., whether the user possesses the actual physical document) and intrinsic factors (i.e., whether the user is the person he/she claims to be).

However, in the related art, identification and verification are performed on user credentials, only one frame of credential image is collected for verification, so that the characteristics of the obtained credential image are limited, and the security and accuracy of credential verification cannot be ensured.

Based on this, the embodiment of the specification provides a method for verifying a certificate, in response to a certificate verification instruction, first determining a first verification policy corresponding to the certificate verification instruction, where the first verification policy is to change a to-be-verified certificate from a first posture to a second posture, then collecting a first posture image of the to-be-verified certificate in the first posture, a second posture image of the to-be-verified certificate in the second posture, and at least one intermediate posture image in the process of changing the to-be-verified certificate from the first posture to the second posture, and finally performing certificate verification according to the first posture image, the second posture image and the at least one intermediate posture image to obtain a certificate verification result corresponding to the to-be-verified certificate; by adopting the method, in the certificate verification process, a plurality of images with different postures of the certificate in the posture change process are collected according to the preset first verification strategy, and the certificate verification is carried out according to the images with different postures of the plurality of certificates, so that the accuracy and the safety of the certificate verification can be effectively improved.

Referring to fig. 1, a schematic flow chart of a certificate verification method is provided in an embodiment of the present disclosure. In the embodiments of the present specification, the certificate verification method is applied to a certificate verification apparatus or an electronic device provided with the certificate verification apparatus. The following details the flow shown in fig. 1, and the certificate verification method specifically includes the following steps:

And the certificate verification device or the electronic equipment provided with the certificate verification device responds to the certificate verification instruction to acquire a first verification strategy corresponding to the certificate verification instruction.

The first verification policy is a preset verification policy corresponding to a certificate verification instruction, and the first verification policy comprises a posture change policy of a certificate to be verified. In this specification embodiment, the first verification policy is to change the pose of the document to be predicted from a first pose to a second pose.

The first gesture is the starting gesture of image acquisition, and the second gesture is the ending gesture of image acquisition. That is, the certificate verification method provided in the embodiment of the present disclosure is used to start the collection of the gesture image when the to-be-verified certificate is in the first gesture, and end the collection of the gesture image when the to-be-verified certificate is in the second gesture, and finally perform the certificate verification according to the collected at least two gesture images, so as to obtain the certificate verification result corresponding to the to-be-verified certificate.

Optionally, in one or more embodiments of the present disclosure, whether the document to be authenticated is included in the display interface is detected frame by frame based on a document detection algorithm.

It can be understood that in the process of collecting the image containing the certificate to be verified based on the image collecting function in real time, the certificate verifying device or the electronic device provided with the certificate verifying device performs certificate detection on each frame of image displayed on the display interface by using a certificate detecting algorithm, and judges whether the image contains the certificate to be verified.

Optionally, in one or more embodiments of the present disclosure, whether the document to be verified is included in the display interface is detected frame by frame, and the image of the document to be verified including the first pose is determined to be the first pose image, or it may be determined that the document to be verified in the image of the document to be verified including the first frame is the first pose, and further it is determined that the image of the document to be verified including the first pose is the first pose image.

It can be understood that whether the display interface contains the certificate to be verified is detected frame by frame, when the first frame is detected to contain the image of the certificate to be verified, the current gesture of the certificate to be verified in the image is taken as a first gesture, and the image is taken as a first gesture image.

Therefore, gesture information detection is performed after the credentials to be verified are contained in the image, and power consumption control of the electronic equipment is facilitated.

It is worth mentioning that when the certificate verification fails, the user can be guided to perform secondary verification, so that the fact that the real certificate fails to pass the certificate verification due to verification errors is avoided. The second authentication policy for the secondary authentication may be different from the first authentication policy.

In a possible embodiment, the first verification policy is to change the document to be verified from a first posture to a second posture, where the first posture may be at a pitch angle of 0 °, the second posture may be at a pitch angle of 30 °, the second verification policy is to change the document to be verified from a third posture to a fourth posture, where the third posture may be at a yaw angle of-20 °, and the fourth posture may be at a yaw angle of 50 °.

The foregoing apparatus embodiments correspond to the method embodiments, and specific descriptions may be referred to descriptions of method embodiment portions, which are not repeated herein. The device embodiments are obtained based on corresponding method embodiments, and have the same technical effects as the corresponding method embodiments, and specific description can be found in the corresponding method embodiments.

The embodiment of the present disclosure further provides a computer storage medium, where the computer storage medium may store a plurality of instructions, where the instructions are adapted to be loaded by a processor and executed by the processor to implement the living body detection model training method according to the embodiment shown in fig. 1 to 6, and the specific implementation process may refer to the specific description of the embodiment shown in fig. 1 to 6, which is not repeated herein.

The present disclosure further provides a computer program product, where the computer program product stores at least one instruction, where the at least one instruction is loaded by the processor and executed by the processor to implement the living body detection model training method according to the embodiment shown in fig. 1 to 6, and the specific execution process may refer to the specific description of the embodiment shown in fig. 1 to 6, which is not repeated herein.

The embodiment of the specification also provides a schematic structural diagram of the electronic device shown in fig. 10. At the hardware level, as in fig. 10, the electronic device includes a processor, an internal bus, a network interface, a memory, and a nonvolatile memory, and may of course include hardware required by other services. The processor reads the corresponding computer program from the nonvolatile memory into the memory and then runs the computer program to realize the voice activity detection method.

Of course, other implementations, such as logic devices or combinations of hardware and software, are not excluded from the present description, that is, the execution subject of the following processing flows is not limited to each logic unit, but may be hardware or logic devices.

In the 90 s of the 20 th century, improvements to one technology could clearly be distinguished as improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software (improvements to the process flow). However, with the development of technology, many improvements of the current method flows can be regarded as direct improvements of hardware circuit structures. Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., field programmable gate array (Field Programmable Gate Array, FPGA)) is an integrated circuit whose logic function is determined by the programming of the device by a user. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented by using "logic compiler" software, which is similar to the software compiler used in program development and writing, and the original code before the compiling is also written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), but not just one of the hdds, but a plurality of kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), lava, lola, myHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, application specific integrated circuits (Application Specific Integrated Circuit, ASIC), programmable logic controllers, and embedded microcontrollers, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, atmel AT91SAM, microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic of the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in a pure computer readable program code, it is well possible to implement the same functionality by logically programming the method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. Such a controller may thus be regarded as a kind of hardware component, and means for performing various functions included therein may also be regarded as structures within the hardware component. Or even means for achieving the various functions may be regarded as either software modules implementing the methods or structures within hardware components.

The system, apparatus, module or unit set forth in the above embodiments may be implemented in particular by a computer chip or entity, or by a product having a certain function. One typical implementation is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

For convenience of description, the above devices are described as being functionally divided into various units, respectively. Of course, the functions of each element may be implemented in one or more software and/or hardware elements when implemented in the present specification.

Furthermore, the present description can take the form of a computer program product on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, etc.) having computer-usable program code embodied therein.

The present description is described with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems) and computer program products according to embodiments of the specification. It will be understood that each flow and/or block of the flowchart illustrations and/or block diagrams, and combinations of flows and/or blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions.

These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.

These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.

In one typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.

The memory may include volatile memory in a computer-readable medium, random Access Memory (RAM) and/or nonvolatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of computer-readable media.

Computer readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of storage media for a computer include, but are not limited to, phase change memory (PRAM), static Random Access Memory (SRAM), dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), read Only Memory (ROM), electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices, or any other non-transmission medium, which can be used to store information that can be accessed by a computing device. Computer-readable media, as defined herein, does not include transitory computer-readable media (transmission media), such as modulated data signals and carrier waves.

It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element.
