[0002] Palm payment is a mobile payment method based on biometric technology. After a user opens the palm payment function, the user can perform palm print scanning in the palm print recognition area of the palm payment device.

[0093] The palm payment method provided by the embodiments of the present application includes a palm payment method on the side of a terminal device (wherein a palm payment application is installed), a palm payment method on the side of a camera module, and a palm payment method on the side of a background server (corresponding to the palm payment application).

[0094] The palm payment method on the side of the terminal device is executed by the terminal device, which can include but is not limited to a mobile phone, a computer, a smart voice interactive device, a smart home appliance, a vehicle-mounted terminal, an aircraft, etc. The palm payment method on the side of the camera module is executed by the camera module, which can include an image acquisition device and a communication device. The image acquisition device can be a three-dimensional camera, for example, wherein software and hardware related to living body detection and / or image quality detection can be added, including a depth camera and an infrared camera. The communication device can be at least one of a wireless communication device (such as a Bluetooth communication device, etc.) and a wired communication device. The palm payment method on the side of the background server is executed by the server, which is an independent physical server, can be a server cluster or a distributed system composed of multiple physical servers, or can be a cloud server.

[0095] It should be understood that the terminal device and the camera module in the embodiments of the present application can be directly or indirectly connected through wired or wireless communication, and the terminal device and the server in the embodiments of the present application can also be directly or indirectly connected through wired or wireless communication, which is not limited in the embodiments of the present application.

[0096] It should be noted that the information (including but not limited to the information exchanged between the terminal device and the camera module, the information exchanged between the terminal device and the background server, etc.), data (including but not limited to palm image data, etc.), and signals involved in the embodiments of the present application are all authorized by the relevant objects or fully authorized by all parties, and the collection, use and processing of the relevant data comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0097] To facilitate understanding of the palm payment method provided by the embodiments of the present application, the palm payment system supporting the palm payment method is introduced first.

[0098] Referring to Figure 1 , Figure 1 The working principle schematic diagram of the palm payment system provided by the embodiments of the present application is shown in FIG. 1. As shown in FIG. 1, the palm payment system includes a camera module 110, a terminal device 120 and a server 130; wherein the palm payment application is installed on the terminal device 120, and the server 130 is a background server corresponding to the palm payment application. The camera module 110 and the terminal device 120 can communicate through wired or wireless mode, and the terminal device 120 and the server 130 can also communicate through wired or wireless mode. Figure 1

[0099] In the embodiments of the present application, the camera module 110 is configured to collect a target palm image and transmit the target palm image to the terminal device 120. Specifically, the camera module 110 can collect multiple palm images of a user as basic palm images when the user's palm is close; then the camera module 110 can perform target screening processing on the multiple basic palm images to retain a target palm image, wherein the target screening processing can include at least one of living body screening and optimization screening, the living body screening is configured to screen and retain a basic palm image corresponding to a living body palm, and the optimization screening is configured to screen and retain a basic palm image with image quality meeting a preset quality requirement; further, the camera module 110 can transmit the retained target palm image to the terminal device 120.

[0100] In the embodiments of the present application, the terminal device 120 is configured to receive the target palm image transmitted by the camera module 110, and further transmit the target palm image to the server 130.

[0101] In the embodiments of the present application, the server 130 is configured to receive the target palm image transmitted by the terminal device 120, find a target object corresponding to the target palm image according to the target palm image, determine a target payment result corresponding to the target palm image according to the finding result, and further return the target payment result to the terminal device 120. Specifically, after receiving the target palm image, the server 130 can find a target object corresponding to the target palm image according to the target palm image; if the target object is found, the corresponding payment operation can be performed based on the payment account of the target object, and a target payment result representing the result corresponding to the payment operation is generated, if the target object is not found, a target payment result representing the failure of palm payment is directly generated; further, the server 130 can feed back the generated target payment result to the terminal device 120.

[0102] ​In the embodiment of the present application, the terminal device 120 is further configured to receive the target payment result returned by the server 130 and prompt the target payment result, so as to inform the merchant and trigger the user related payment result of the palm payment.

[0103] In this way, the camera module 110 and the terminal device 120 installed with the palm payment application are used to replace the special palm payment device in the related art. Since the camera module 110 is simple to configure and only includes related image acquisition devices and communication devices, and the palm payment application can be installed on any common terminal device in daily life, the deployment cost of the palm payment service is greatly reduced. When the merchant accesses the palm payment service, only the low-cost camera module 110 needs to be deployed, and the palm payment application needs to be installed on the commonly used terminal device 120, without the need to deploy the high-cost special palm payment device, thereby improving the convenience of the merchant accessing the palm payment service and facilitating the popularization and promotion of the palm payment. In addition, the server 130 can provide corresponding background service support in the palm payment process, thereby ensuring that the palm payment service is stable and reliable.

[0104] The palm payment method provided by the present application will be described in detail through the method embodiment.

[0105] Referring to Figure 2 , Figure 2 The flowchart of the palm payment method on the terminal device side provided by the embodiment of the present application is shown. It should be understood that the terminal device used to execute the palm payment method is installed with a palm payment application, which is an application program used to realize the palm payment service in combination with the camera module. As Figure 2 shown, the palm payment method includes the following steps:

[0106] Step 201: receiving the target palm image transmitted by the camera module.

[0107] In the embodiment of the present application, when the user uses the palm payment function, the palm can be aimed at the camera module; correspondingly, the camera module can acquire the palm image of the user, determine the target palm image from the acquired palm image, and then transmit the target palm image to the terminal device which establishes a communication connection and is installed with the palm payment application.

[0108] It should be noted that the camera module in the embodiment of the present application is a device for collecting and transmitting palm images to a terminal device. The camera module can be composed of a camera component for collecting palm images, a communication component for transmitting palm images, and a basic power supply component. Among them, the camera component for collecting palm images can be a traditional camera with lower cost, or a three-dimensional camera with image detection and screening function; the three-dimensional camera adds image detection and screening related software and hardware compared with the traditional camera, such as software and hardware related to living body screening (for detecting whether the collected palm image corresponds to a living palm, and screening palm images corresponding to a living palm), software and hardware related to image quality detection and screening (for detecting the quality of the image, such as detecting the size of the palm, the angle of the palm, the contrast of the image, the brightness of the image, the definition of the image, and other indicators in the collected image, and screening the palm image with better image quality accordingly), etc., and the three-dimensional camera can specifically include a depth camera and an infrared camera. The communication component for transmitting palm images can be a component supporting wireless communication (such as Bluetooth communication), or a component supporting wired communication (such as communication through a data line).

[0109] It should be noted that the target palm image is a palm image transmitted by the camera module to the terminal device installed with the palm brushing payment application. The target palm image can be the palm image originally collected by the camera module, for example, when the camera component in the camera module is a traditional camera, the target palm image is the palm image originally collected by the camera module. The target palm image can also be a palm image retained after screening processing by the camera module, for example, when the camera component in the camera module is a three-dimensional camera with added software and hardware related to living body screening and image quality detection and screening, the target palm image can be a palm image retained after at least one of living body screening and optimization screening by the camera model, wherein the living body screening can screen and retain palm images corresponding to a living palm, and the optimization screening can screen and retain palm images with image quality meeting the preset quality requirements.

[0110] As an example, the terminal device installed with the palm brushing payment application can establish a Bluetooth connection with the camera module, when the user triggers the palm brushing payment, the camera module can collect a video stream including the user's palm, and perform living body screening and optimization screening on the video frames in the video stream to screen and retain video frames corresponding to a living palm and meeting the preset quality requirements as target palm images, and then transmit the target palm images to the terminal device installed with the palm brushing payment application through Bluetooth.

[0111] It should be understood that the target palm image transmitted by the camera module to the terminal device can be one or more, and the number of target palm images transmitted by the camera module to the terminal device is not limited in the embodiment of the present application.

[0112] Step 202: transmitting the target palm image to a background server corresponding to the palm brushing payment application; the background server is configured to find a target object corresponding to the target palm image according to the target palm image, and determine a target payment result corresponding to the target palm image according to a finding result.

[0113] After the terminal device receives the target palm image transmitted by the camera module, the terminal device can further transmit the target palm image to a background server corresponding to the palm brushing payment application, so that the background server completes a corresponding palm brushing payment service based on the target palm image.

[0114] It should be noted that the background server corresponding to the palm brushing payment application in the embodiments of the present application is configured to provide background support for the palm brushing payment service. Specifically, the background server can find a target object corresponding to a target palm image transmitted by a terminal device, i.e., find a user corresponding to the target palm image, according to the target palm image. If the target object is found, the background server can further deduct a corresponding amount of money from a payment account corresponding to the target object, and accordingly generate a target payment result corresponding to the target palm image. It should be understood that if the deduction of the amount of money is successful, the generated target payment result indicates that the palm brushing payment is successful, and if the deduction of the amount of money fails (e.g., due to insufficient balance in the payment account), the generated target payment result indicates that the palm brushing payment fails. If the target object is not found, the background server can directly generate a target payment result indicating that the palm brushing payment fails. Then, the background server can return the generated target payment result to the terminal device.

[0115] It should be understood that in actual applications, in a case where the target palm image transmitted by the camera module to the terminal device is a raw palm image collected by the camera module, the terminal device can perform a screening process on the target palm image through the palm brushing payment application in the terminal device. For example, the terminal device can perform at least one of a living body screening and an optimization screening on the received target palm image, and then transmit the target palm image remaining after the screening process to the background server. In a case where the target palm image transmitted by the camera module to the terminal device is a palm image remaining after the screening process of the camera module, the terminal device can directly forward the received target palm image to the background server. That is, in the embodiments of the present application, the screening process on the raw collected palm image can be performed by the camera module or the terminal device.

[0116] Step 203: receiving the target payment result returned by the background server, and prompting the target payment result.

[0117] After receiving the target payment result returned by the background server corresponding to the palm payment application, the terminal device can prompt the target payment result, so as to make the merchant and the user triggering the palm payment know the payment result of the palm payment.

[0118] It should be understood that the terminal device can prompt the target payment result in the following ways: displaying the target payment result on the screen of the terminal device, or playing the voice corresponding to the target payment result through the terminal device. The embodiments of the present application do not limit the prompting manner of the target payment result. In addition, the target payment result can reflect the payment amount corresponding to the palm payment, the payment account used for the palm payment, and the like, in addition to reflecting whether the palm payment is successful. The embodiments of the present application do not limit the content reflected by the target payment result.

[0119] In a possible implementation, the terminal device installed with the palm payment application in the embodiments of the present application can be a terminal device provided by a merchant, for example, the palm payment application can be installed on the terminal device (such as a mobile phone) of a merchant staff, the terminal device establishes a communication connection with the camera module, and receives the target palm image transmitted by the camera module. In this way, the security of the commodity transaction is ensured, and the merchant participates in the palm payment process of the user and knows the result of the palm payment in time.

[0120] In another possible implementation, the terminal device installed with the palm payment application in the embodiments of the present application can also be a terminal device of a user triggering the transaction through the palm payment.

[0121] For example, assuming that the user a needs to pay for the selected goods through the palm payment, the user a can establish a communication connection between the terminal device carried by the user a and the camera module for collecting the palm image. For example, the terminal device can establish a communication connection with the camera module based on the near field communication (NFC) technology, that is, the user a can bring the terminal device close to the camera module, the terminal device recognizes the existence of the camera module (the camera module is also configured with a corresponding induction chip) through the induction chip installed in the terminal device, and the terminal device and the camera module can establish a communication connection after successfully recognizing the camera module. It should be understood that the terminal device and the camera module can also be connected in other ways in actual application, and the embodiments of the present application do not limit the connection manner.

[0122] After the terminal device prompts that the communication connection between the terminal device and the camera module is successfully established, the user A can aim his palm at the camera module. The camera module correspondingly collects the palm image of the user A to obtain a target palm image, and sends the target palm image to the terminal device of the user A through the established communication connection. The terminal device sends the target palm image to the background server corresponding to the palm payment application.

[0123] In this way, by the above manner, the terminal device carried by the user who triggers the palm payment is used to perform the relay task of the target palm image, which can further reduce the cost required by the merchant to deploy the palm payment service, i.e., the merchant only needs to deploy the camera module for collecting the palm image. In addition, the terminal device carried by the user relays the target palm image, which can better ensure the security of the target palm image, i.e., avoiding the terminal device of other users from obtaining the target palm image, so as to avoid the palm image information from being leaked. Moreover, the terminal device carried by the user relays the target palm image, which can further improve the convenience of the palm payment, i.e., the user can complete the payment by himself. In a possible implementation manner, one camera module can be deployed in one merchant, i.e., the camera module can establish a communication connection with the terminal device provided by the merchant and installed with the palm payment application, and the camera module is used to perform the palm payment service of the merchant.

[0124] In another possible implementation manner, one camera module can be shared by multiple merchants, such as multiple merchants (the distance between the multiple merchants does not exceed a preset distance threshold) located within a preset range. The camera module can establish a communication connection with the terminal device provided by each of the multiple merchants and installed with the palm payment application. In order to enable the camera module to support the palm payment service of the multiple merchants, a moving device (such as a wheel installed at the bottom of the camera module, a propeller installed at the top of the camera module, etc.) and a corresponding moving control device can be installed on the camera module, so as to facilitate the camera module to move to the corresponding merchant.

[0125] In the implementation, after the camera module and the terminal device of the merchant establish the communication connection, the camera module can obtain the merchant location information provided by the terminal device, and record the correspondence between the identifier of the terminal device and the merchant location information. Correspondingly, in actual application, if a merchant to which a terminal device establishing a communication connection with the camera module belongs needs to use the palm payment service, the merchant can correspondingly trigger the calling instruction for the camera module through the palm payment application on the terminal device, that is, the terminal device can send the calling instruction to the camera module. After receiving the calling instruction, the camera module can find the merchant location information corresponding to the terminal device sending the calling instruction based on the correspondence between the identifier of the terminal device and the merchant location information recorded in advance by the camera module, and then control the camera module to move to the merchant to which the terminal device belongs through the motion controller and the motion device on the camera module, and perform the palm image acquisition task.

[0126] In this way, by sharing one camera module for performing the palm payment service by multiple merchants, the cost of the merchants accessing the palm payment service can be further reduced, and the popularization and promotion of the palm payment service are facilitated.

[0127] The palm payment method provided by the embodiment of the present application uses the camera module and the terminal device installed with the palm payment application to replace the dedicated palm payment device in the related art. Since the camera module used has a simple configuration, only the related image acquisition device and the communication device are included, and the palm payment application can be installed on any common terminal device in daily life, the deployment cost of the palm payment service is greatly reduced. When the merchant accesses the palm payment service, only the low-cost camera module needs to be deployed, and the palm payment application needs to be installed on the commonly used terminal device, without the need to deploy the high-cost dedicated palm payment device. In this way, the convenience of the merchant accessing the palm payment service is improved, and the popularization and promotion of the palm payment are facilitated.

[0128] In a possible implementation, before the terminal device completes the installation operation of the palm payment application and establishes the communication connection with the camera module, the method provided by the embodiment of the present application further includes:

[0129] Performing security check on the running environment of the palm payment application to obtain an environment check result. If the environment check result indicates that the running environment of the palm payment application meets the preset security requirement, the communication connection with the camera module is established.

[0130] In the embodiments of the present application, if a merchant or a user wants to access the palm payment service, the merchant or the user can download the palm payment application from the official platform and install the palm payment application on the terminal device. Since the palm payment application is installed on the terminal device of the merchant side, in order to ensure the security of the palm payment service, the running environment of the palm payment application needs to be checked for security before the palm payment application is officially used, that is, after the palm payment application is started, the running environment of the palm payment application can be automatically checked for security. If the obtained environment check result indicates that the running environment of the palm payment application meets the preset security requirement, it means that the running environment of the palm payment application is secure, and the security of the palm payment service can be ensured, at this time, the terminal device and the camera module can be allowed to establish a communication connection, that is, the terminal device is allowed to obtain the palm image in the palm payment; if the obtained environment check result indicates that the running environment of the palm payment application does not meet the preset security requirement, it means that the running environment of the palm payment application is not secure, and it is difficult to ensure the security of the palm payment service, at this time, the terminal device and the camera module are not allowed to establish a communication connection, that is, the terminal device is not allowed to obtain the palm image collected by the camera module.

[0131] It should be noted that the running environment of the palm payment application can be checked for security from the following aspects: whether the terminal device on which the palm payment application is installed is secure, whether the network environment in which the terminal device on which the palm payment application is installed is located is secure, whether the installed palm payment application itself is secure, and whether the file storage space occupied by the installed palm payment application in the terminal device is secure. If the environment check results obtained through each security check are all safe, it can be considered that the running environment of the palm payment application meets the preset security requirement, at this time, the terminal device and the camera module can be allowed to establish a communication connection, if the environment check result obtained through at least one security check is unsafe, it can be considered that the running environment of the palm payment application does not meet the preset security requirement, at this time, the terminal device and the camera module will not be allowed to establish a communication connection.

[0132] In this way, by the above-mentioned manner, the security of the running environment of the palm payment application is ensured, that is, the terminal device and the palm payment application accessing the palm payment service meet the specific security requirement, so as to avoid the palm payment service being illegally attacked and stolen, and the security and reliability of the palm payment service are ensured.

[0133] As an example, the running environment of the palm payment application can be checked for security, which can include at least one of the following security check manners:

[0134] 1) Check whether the target management permission of the terminal device on which the palm payment application is installed is modified.

[0135] The target management permission of the terminal device is checked, which is a way to check whether the terminal device installed with the palm swiping payment application is safe.

[0136] The target management permission can be a super management permission (root permission) of the terminal device. The super management permission is a kind of system management permission, and can also be referred to as root permission. An object obtaining the super management permission can perform operations such as adding, deleting, modifying, and inquiring any file in the terminal device system. In order to ensure the safety of the files in the terminal device, the super management permission is usually locked before the terminal device is shipped.

[0137] Since the application runs on the terminal device with the modified super management permission, the safety of the application cannot be guaranteed. Therefore, in the embodiments of the present application, whether the super management permission of the terminal device installed with the palm swiping payment application is modified, i.e., whether the terminal device is rooted, is checked. If it is found that the super management permission of the terminal device is modified, it is determined that the terminal device installed with the palm swiping payment application is not safe. For example, the RootBeer library or whether the system directory is writable is checked to check whether the super management permission of the terminal device is modified. Of course, in actual applications, other ways can also be used to check whether the super management permission of the terminal device is modified, and the embodiments of the present application do not make any limitation in this regard.

[0138] 2) Check whether the palm swiping payment application runs in a virtualization environment or an emulator.

[0139] The check whether the palm swiping payment application runs in a virtualization environment or an emulator is a way to check whether the terminal device installed with the palm swiping payment application is safe.

[0140] In some cases (such as application debugging), the application can run in a virtualization environment or an emulator, which is different from running in a physical device. The application running in a virtualization environment or an emulator has a high security risk, and the application itself and the data in the application are easy to be modified and attacked.

[0141] Based on this, in the embodiments of the present application, it can be checked whether the palm payment application is running in a virtualization environment or an emulator. If it is found that the palm payment application is running in a virtualization environment or an emulator, it can be determined that the palm payment application is not installed on a real terminal device, and the running environment of the palm payment application is not safe. For example, the CPU (Central Processing Unit) information, hardware parameters, system attributes and the like can be checked to check whether the palm payment application is running in a virtualization environment or an emulator. Of course, in actual application, other manners can also be used to check whether the palm payment application is running in a virtualization environment or an emulator, and the embodiments of the present application do not make any limitation in this regard.

[0142] 3) Check the system version and security patch version of the terminal device on which the palm payment application is installed.

[0143] Checking the system version and security patch version of the terminal device is a manner for checking whether the terminal device on which the palm payment application is installed is safe.

[0144] Generally, if the system version of the terminal device is too low or the security patch version is too old, the terminal device has a high possibility of having security vulnerabilities and being easily exploited by attackers.

[0145] Based on this, in the embodiments of the present application, the system version and security patch version of the terminal device on which the palm payment application is installed can be checked. If the system version is lower than a preset system version or the security patch version is lower than a preset security patch version, it indicates that the system version of the terminal device is too low or the security patch version is too old, and the security of the terminal device is not high enough. At this time, it can be determined that the terminal device on which the palm payment application is installed is not safe. For example, Build.VERSION.SDK_INT and SecurityPatchChecker can be used to check the system version and security patch version of the terminal device. Of course, in actual application, other manners can also be used to check the system version and security patch version of the terminal device, and the embodiments of the present application do not make any limitation in this regard.

[0146] 4) Check whether the application signature and permission of the palm payment application are correct.

[0147] Checking whether the application signature and permission of the palm payment application are correct is a manner for checking whether the installed palm payment application itself is safe.

[0148] In actual application, the developer of the palm payment application sets the corresponding application signature and permission for the palm payment application to ensure the security of the palm payment application. The application signature can ensure that the palm payment application is not tampered with, and the permission can ensure that the data of the palm payment application is not stolen.

[0149] Therefore, in the embodiments of the present application, the application signature and permission of the palm payment application can be checked. That is, whether the application signature of the palm payment application installed in the terminal device is consistent with the application signature set by the developer for the palm payment application, and whether the permission of the palm payment application installed in the terminal device is consistent with the permission set by the developer for the palm payment application are checked. If at least one of them is inconsistent, such as the application signature is tampered with or the permission is abused, it indicates that the palm payment application may have a security risk, that is, the palm payment application is determined to be unsafe. For example, the signature and permission of the palm payment application can be checked by using classes such as PackageManager and PackageInfo. Of course, in actual application, other ways can also be used to check the signature and permission of the palm payment application, and the embodiments of the present application do not make any limitation in this regard.

[0150] 5) Check the network environment and proxy settings of the terminal device on which the palm payment application is installed.

[0151] Checking the network environment and proxy settings of the terminal device is one way to check whether the network environment of the terminal device is secure.

[0152] In actual application, if the network environment of the terminal device is not secure, such as connecting to an untrusted network, the data exchanged between the terminal device and the server may be at risk of being attacked. In addition, if the terminal device sets a proxy, that is, a network proxy is set between the terminal device and the server to transfer data, the network proxy can obtain the data exchanged between the terminal device and the server, and accordingly, the risk of data theft attack is also easy to occur.

[0153] Therefore, in the embodiments of the present application, the network environment of the terminal device on which the palm payment application is installed can be checked to determine whether it is secure. That is, whether the network connected by the terminal device is trusted, and whether the network proxy is set by the terminal device are checked. If it is found that the network connected by the terminal device is not trusted, or it is found that the network proxy is set by the terminal device, it can be determined that the network environment of the terminal device is not secure. For example, the network environment and proxy settings of the terminal device can be checked by using classes such as NetworkInfo and Proxy. Of course, in actual application, other ways can also be used to check the network environment and proxy settings of the terminal device, and the embodiments of the present application do not make any limitation in this regard.

[0154] 6) checking the permission of the file storage space corresponding to the palm payment application.

[0155] Checking the permission of the file storage space corresponding to the palm payment application is a way to check whether the file storage space occupied by the palm payment application in the terminal device is safe.

[0156] In actual application, if the permission of the file storage space occupied by the application in the terminal device is acquired by other objects, it indicates that the object can access the data in the application from the file storage space, and then the data in the application will exist security risks.

[0157] Based on this, in the embodiments of the present application, it can be checked whether the permission of the file storage space corresponding to the palm payment application is acquired by other objects except the palm payment application itself. If it is found by checking that other objects acquire the permission of the file storage space corresponding to the palm payment application, it indicates that other objects can acquire the data in the palm payment application, that is, it indicates that the data in the palm payment application exists security risks. Exemplarily, the permission of the file storage space corresponding to the palm payment application can be checked by using classes such as PackageManager and File. Of course, in actual application, other ways can also be used to check the permission of the file storage space corresponding to the palm payment application, and the embodiments of the present application do not make any limitation in this regard.

[0158] In this way, by using one or more checking ways described above to check whether the running environment of the palm payment application is safe, the safety of the terminal device itself on which the palm payment application is installed, the safety of the palm payment application itself, the safety of the network environment in which the terminal device is located, and the safety of the data in the palm payment application can be reliably ensured, so as to ensure the safety and reliability of the palm payment service.

[0159] It should be understood that in actual application, other checking ways can also be used to check whether the running environment of the palm payment application is safe from other dimensions, and the embodiments of the present application do not make any limitation in this regard.

[0160] In a possible implementation, after the terminal device on which the palm payment application is installed establishes a communication connection with the camera module, before the camera module transmits the target palm image to the terminal device, the method provided by the embodiments of the present application further includes:

[0161] The terminal device receives first encrypted identity information transmitted by the camera module, the first encrypted identity information being obtained by encrypting identity information of the camera module. The terminal device transmits second encrypted identity information to the background server, the second encrypted identity information being obtained by encrypting the identity information of the camera module and identity information of the palm payment application. The terminal device receives an identity verification result returned by the background server, the identity verification result being obtained by the background server verifying the identity information of the camera module and the identity information of the palm payment application. If the identity verification result indicates that the identity verification of the camera module is passed and the identity verification of the palm payment application is passed, it is determined that the communication connection between the terminal device and the camera module is safe, and the safe communication connection can support transmission of the palm image.

[0162] In the embodiments of the present application, before the terminal device installed with the palm payment application and the camera module jointly implement the palm payment service, the identity of the camera module and the palm payment application can be verified by means of the background server corresponding to the palm payment application, so as to ensure that the camera module accessing the palm payment service is a legal camera module, and the palm payment application accessing the palm payment service is a legal palm payment application, and further ensure the security of the palm payment service.

[0163] Figure 3 The signaling interaction diagram in the identity verification process provided by the embodiments of the present application will be described below in conjunction with the signaling interaction process shown in Figure 3 It should be noted that after the communication connection is established between the terminal device and the camera module, the public key exchange can be performed first, that is, the terminal device provides its own public key (hereinafter referred to as the first public key) to the camera module, and the camera module provides its own public key (hereinafter referred to as the second public key) to the terminal device, so as to facilitate subsequent encrypted communication between the terminal device and the camera module.

[0164] As shown in Figure 3As shown, the camera module can encrypt its identity information (such as identity identifier, identity signature, etc.) by using the first public key to obtain first encrypted identity information. In addition, in order to ensure the integrity of the first encrypted identity information, the camera module can also generate first signature identity information based on the first encrypted identity information, and then transmit the first encrypted identity information and the first signature identity information to the terminal device through the communication connection between the camera module and the terminal device. After receiving the first encrypted identity information and the first signature identity information, the terminal device can first verify the integrity of the first encrypted identity information based on the first signature identity information. For example, the terminal device can calculate the first signature identity information based on the received first encrypted identity information, and if the calculated first signature identity information is the same as the actually received first signature identity information, it can be determined that the first encrypted identity information has not been tampered with. Then, the terminal device can decrypt the first encrypted identity information by using its own private key (which can be referred to as the first private key) to obtain the identity information of the camera module.

[0165] In addition, the terminal device can encrypt the identity information of the palm payment application (such as the APK (Android application package) package name and APK signature of the palm payment application) and the identity information of the camera module to obtain second encrypted identity information. It should be understood that the terminal device can pre-acquire the public key (which can be referred to as the third public key) of the background server, and then encrypt the identity information of the palm payment application and the identity information of the camera module by using the third public key to obtain the second encrypted identity information. In addition, in order to ensure the integrity of the second encrypted identity information, the terminal device can also generate second signature identity information based on the second encrypted identity information, and then transmit the second encrypted identity information and the second signature identity information to the background server.

[0166] After receiving the second encrypted identity information and the second signed identity information transmitted by the terminal device, the background server can first verify the integrity of the second encrypted identity information based on the second signed identity information. For example, the background server can calculate the second signed identity information based on the received second encrypted identity information. If the calculated second signed identity information is the same as the actually received second signed identity information, it can be determined that the second encrypted identity information has not been tampered with. Then, the background server can decrypt the second encrypted identity information using its own private key (which can be referred to as a third private key) to obtain the identity information of the palm payment application and the identity information of the camera module. Further, the server can verify the identity of the palm payment application and the camera module, respectively, for example, based on the APK package name and the APK signature of the palm payment application to verify whether the palm payment application is legal, and based on the identity of the camera model to verify whether the camera module is legal, thereby obtaining the corresponding identity verification result, which represents whether the identity of the palm payment application is verified and whether the identity of the camera module is verified, and feeding back the identity verification result to the terminal device.

[0167] The terminal device receives the identity verification result. If the identity verification result indicates that the identity of the palm payment application is verified and the identity of the camera module is verified, it can be determined that the communication connection between the terminal device and the camera module is secure. If the identity verification result indicates that the identity of the palm payment application is not verified and / or the identity of the camera module is not verified, it can be determined that the communication connection between the terminal device and the camera module is not secure, and the communication connection between the terminal device and the camera module needs to be cut off. It should be noted that in the embodiments of the present application, only the communication connection that is confirmed to be secure can support the transmission of palm images, that is, the palm payment business needs to be implemented based on a secure communication connection between the camera module and the terminal device.

[0168] In this way, by the above method, before the terminal device installed with the palm payment application and the camera module jointly perform the palm payment business, the identity of the palm payment application in the terminal device and the identity of the camera module are verified by the background server, which ensures that the camera module accessing the palm payment business is a legal camera module, and ensures that the palm payment application accessing the palm payment business is a legal application, thereby providing security guarantee for subsequent palm payment business. In addition, in the above identity verification process, the identity information of the palm payment application and the identity information of the camera module are transmitted in an encrypted manner, which can avoid the identity information of the palm payment application and the identity information of the camera module being leaked, and further improves the security of the entire identity verification process.

[0169] In a possible implementation, the terminal device receives the target palm image transmitted by the camera module, specifically comprising:

[0170] receive a first encrypted message transmitted by the camera module, the first encrypted message comprising encrypted image information and first signature information, the encrypted image information being obtained by encrypting a target palm image, and the first signature information being generated based on the encrypted image information. Then, integrity verification is performed on the encrypted image information based on the first signature information. If the integrity verification is passed, the encrypted image information is decrypted to obtain the target palm image.

[0171] Specifically, in the embodiments of the present application, when the camera module transmits the target palm image to the terminal device, the target palm image needs to be encrypted. As introduced above, after the communication connection is established between the terminal device and the camera module, the public keys of each other can be exchanged, based on which the camera module can use the obtained public key of the terminal device (i.e., the first public key) to encrypt the target palm image to obtain encrypted image information. In order to ensure that the encrypted image information is not tampered with during transmission, the camera module can also generate first signature information based on the encrypted image information, for example, can calculate the corresponding hash value based on the encrypted image information, and generate the first signature information accordingly. Further, the camera module can add the above encrypted image information and the first signature information to the first encrypted message, and send the first encrypted message to the terminal device.

[0172] After the terminal device receives the first encrypted message, the terminal device can first perform integrity verification on the encrypted image information in the first encrypted message based on the first signature information in the first encrypted message. Specifically, the terminal device can calculate the first signature information based on the encrypted image information in the first encrypted message, and compare whether the calculated first signature information is consistent with the first signature information in the first encrypted message. If they are consistent, it can be determined that the encrypted image information has not been tampered with during transmission and has passed the integrity verification. At this time, the terminal device can use its own private key (i.e., the first private key) to decrypt the encrypted image information, thereby obtaining the target palm image.

[0173] In this way, by the above method, the target palm image is transmitted to the terminal device based on the encryption and signature mechanism, which can ensure the integrity and confidentiality of the transmitted target palm image, thereby ensuring the security and reliability of the palm payment service, and avoiding the target palm image being stolen during transmission.

[0174] In a possible implementation, the terminal device also transmits control instructions to the camera module to control the camera module to perform relevant actions, such as turning on, turning off, collecting images, rotating by a specific angle, etc. The terminal device can transmit control instructions to the camera module in the following way:

[0175] transmit a second encrypted message to the camera module, the second encrypted message comprising encrypted instruction information and second signature information, the encrypted instruction information being obtained by encrypting a control instruction for the camera module, and the second signature information being generated based on the encrypted instruction information.

[0176] Specifically, in the embodiments of the present application, when the terminal device transmits a control instruction to the camera module, the control instruction needs to be encrypted. As introduced above, after the communication connection is established between the terminal device and the camera module, the public keys of each other can be exchanged, based on which the terminal device can encrypt the control instruction for the camera module by using the obtained public key of the camera module (i.e. the second public key), to obtain encrypted instruction information. In order to ensure that the encrypted instruction information is not tampered with during transmission, the terminal device can also generate second signature information based on the encrypted instruction information, for example, can calculate the corresponding hash value based on the encrypted instruction information, and generate the second signature information accordingly. Further, the terminal device can add the above-mentioned encrypted instruction information and second signature information to the second encrypted message, and send the second encrypted message to the camera module.

[0177] After the camera module receives the second encrypted message, it can first verify the integrity of the encrypted instruction information therein based on the second signature information therein. Specifically, the camera module can calculate the second signature information based on the encrypted instruction information in the second encrypted message, and compare whether the calculated second signature information is consistent with the second signature information in the second encrypted message. If they are consistent, it can be determined that the encrypted instruction information has not been tampered with during transmission and has passed the integrity verification. At this time, the camera module can decrypt the encrypted instruction information by using its own private key (i.e. the second private key), thereby obtaining the control instruction and executing the corresponding action accordingly.

[0178] In this way, by the above-mentioned manner, the control instruction is transmitted to the camera module based on the encryption and signature mechanism, which can ensure the integrity and confidentiality of the transmitted control instruction, thereby ensuring the security and reliability of the palm payment business, and avoiding the control instruction being stolen during transmission.

[0179] It should be noted that after the communication connection between the terminal device and the camera module is closed, the terminal device and the camera module need to clear the held keys accordingly, such as clearing its own private key and the public key of the other party, so as to protect the security of the communication.

[0180] It should be understood that, in the embodiments of the present application, in order to ensure that the data exchanged between the terminal device and the background server is not stolen by an attack, the data exchanged between the terminal device and the background server also needs to be encrypted. Specifically, the terminal device and the background server can exchange data through an encrypted communication channel, or can encrypt the data exchanged by using a corresponding key, or can encrypt the data exchanged by using other encryption methods. The embodiments of the present application do not limit the encryption method of the data exchanged between the terminal device and the background server.

[0181] In a possible implementation, the method provided by the embodiments of the present application further includes:

[0182] The process setting program in the palm payment application is used to control the process corresponding to the palm payment application to remain in a live state in the terminal device.

[0183] In the embodiments of the present application, in order to ensure that the palm payment service can be continuously and normally and stably performed, it is necessary to ensure that the process corresponding to the palm payment application remains in a live state in the terminal device, that is, to ensure that the resources occupied by the palm payment application in the terminal device are not preempted by other applications. Once the process corresponding to the palm payment application is closed by the system, the palm payment service will not be normally performed. When the palm payment application is installed on a terminal device provided by a merchant, it is particularly important to ensure that the process corresponding to the palm payment application remains in a live state.

[0184] As an example, the priority of the process corresponding to the palm payment application can be set to a high priority, so as to ensure that the process is not closed by the system. Specifically, the startForeground() program can be used to set the service of the palm payment application to a foreground service, and the setThreadPriority() program can be used to set the priority of the corresponding thread to a high priority.

[0185] As another example, the AlarmManager (timing prompt service) program can also be used to enable the service of the palm payment application at a timing, so as to ensure that the palm payment application is periodically run, thereby keeping the process corresponding to the palm payment application in a live state.

[0186] As another example, the JobScheduler (job scheduling) program can also be used to execute a background task. The JobScheduler program can determine the running time of the palm payment application according to the resource occupation of the system of the terminal device, thereby ensuring that the service of the palm payment application is not closed by the system.

[0187] Of course, in actual application, other manners can also be adopted to control the process corresponding to the palm payment application to keep alive in the terminal device, and the embodiments of the present application do not make any limitation in this aspect.

[0188] In this way, by controlling the process corresponding to the palm payment application to keep alive in the terminal device, the palm payment service can be effectively ensured to continuously and normally proceed, i.e., the stability of the palm payment service is ensured.

[0189] In a possible implementation manner, the terminal device can prompt the target payment result fed back by the background server in the following manner:

[0190] The target payment result is displayed through the target floating window created by the floating window creation program in the palm payment application.

[0191] In the embodiments of the present application, in order to conveniently display the target payment result on the terminal device and not to affect the use of other functions of the terminal device, the target payment result can be displayed through the target floating window displayed on the front interface of the terminal device, Figure 4 A schematic diagram of a target floating window provided in the embodiments of the present application is shown in Figure 4 The target floating window is displayed on the front interface of the terminal device and occupies part of the front interface.

[0192] As an example, the target floating window displayed in suspension can be added through the Window Manager program in the palm payment application, and this method needs to apply for the SYSTEM_ALERT_WINDOW permission. As another example, a floating dialog box can be created as the target floating window through the DialogFragment program, and the target floating window can be moved and scaled. As another example, a pop-up window can be created as the target floating window through the PopupWindow program.

[0193] Of course, in actual application, other manners can also be adopted to create the target floating window, and the embodiments of the present application do not make any limitation in this aspect.

[0194] In this way, by prompting the payment result corresponding to the palm payment service through the target floating window, on the one hand, the palm payment result can be conveniently prompted, and on the other hand, the palm payment service can be prevented from affecting other functions on the terminal device.

[0195] Referring to Figure 5 , Figure 5 A flowchart of a palm payment method provided in the embodiments of the present application is shown in Figure 5 The palm payment method includes the following steps:

[0196] Step 501: Collect multiple basic palm images.

[0197] In the embodiment of the present application, the camera module used to implement the palm payment service can collect multiple palm images of the user as basic palm images when the user triggers the palm payment.

[0198] It should be noted that the basic palm image in the embodiment of the present application is the palm image originally collected by the camera module. Specifically, it can be a video frame image in the palm video stream collected by the camera module, for example, each video frame image in the palm video stream collected by the camera module can be used as a basic palm image, or a certain sampling rule can be used to extract several video frame images from the palm video stream collected by the camera module as basic palm images. Specifically, it can also be a palm image captured by the camera module at a preset shooting interval (such as 20 ms, etc.).

[0199] As an example, the camera module can collect basic palm images in response to an image collection instruction sent by a terminal device installed with a palm payment application; for example, when the user triggers the palm payment, the merchant can send an image collection instruction to the camera module through the palm payment application on the terminal device, and the camera module can start collecting basic palm images after receiving the image collection instruction. Of course, in actual application, the camera module can also be triggered to collect basic palm images through other triggering methods, such as automatically triggering the collection of basic palm images when the camera module detects that the user's palm is close, etc. The embodiment of the present application does not make any limitation on the way of triggering the camera module to collect basic palm images.

[0200] Step 502: Perform target screening processing on the multiple basic palm images to obtain target palm images; the target screening processing includes at least one of living body screening and optimization screening, the living body screening is used to screen and retain basic palm images corresponding to living body palms, and the optimization screening is used to screen and retain basic palm images with image quality meeting a preset quality requirement.

[0201] After the camera module collects multiple basic palm images, target screening processing can be performed on the multiple basic palm images to obtain target palm images that are conducive to the smooth implementation of the palm payment service.

[0202] It should be noted that in the embodiments of the present application, the target screening processing can include at least one of living body screening and optimization screening. Among them, the living body screening is used to screen and retain the basic palm image corresponding to the living body palm, so as to avoid the palm image corresponding to the non-living body palm attacking the palm payment service, and ensure the safety and reliability of the palm payment service. The optimization screening is used to screen and retain the basic palm image with image quality meeting the preset quality requirement, that is, to screen and retain the basic palm image with high image quality, so as to ensure that the background server can smoothly execute the palm payment service according to the received palm image.

[0203] As an example, the living body screening can be realized by a corresponding living body detection model, which is used to analyze the relevant living body features in the input palm image and determine whether the palm image corresponds to the living body palm. Specifically, the camera module can input the collected basic palm image into the living body detection model, and the living body detection model can output the probability that the basic palm image corresponds to the living body palm by analyzing and processing the input basic palm image. If the probability exceeds the preset probability threshold, it can be considered that the basic palm image corresponds to the living body palm, and the basic palm image is retained. Otherwise, if the probability does not reach the preset probability threshold, it can be considered that the basic palm image does not correspond to the living body palm, and the basic palm image is discarded.

[0204] As an example, the optimization screening can be realized by a corresponding image quality detection model, which is used to evaluate the input palm image from multiple dimensions, such as the size of the palm in the image, the angle of the palm, the contrast of the image, the brightness of the image, the definition of the image, etc. Finally, the score corresponding to the palm image is obtained. Specifically, the camera module can input the collected basic palm image into the image quality detection model, and the image quality detection model can evaluate the basic palm image and output the score corresponding to the basic palm image. If the score exceeds the preset score threshold, it can be considered that the quality of the basic palm image is better, and the basic palm image can be retained. Otherwise, if the score does not reach the preset score threshold, it can be considered that the quality of the basic palm image is poor, and the basic palm image can be discarded.

[0205] It should be understood that in the embodiments of the present application, when the target screening processing retains both the living body screening and the optimization screening, the living body screening can be performed first to retain the basic palm image corresponding to the living body palm, thereby preferentially ensuring the safety of the palm payment service. Then, based on the basic palm image retained by the living body screening, the optimization screening is performed to further retain the basic palm image with better image quality as the target palm image, thereby ensuring the smooth progress of the palm payment service.

[0206] In step 503, the target palm image is transmitted to a terminal device installed with a palm payment application; the terminal device is configured to transmit the target palm image to a background server of the palm payment application; and the background server is configured to determine a target payment result corresponding to the target palm image based on the target palm image.

[0207] After the camera module retains the target palm image through the target screening process, the target palm image can be transmitted to a terminal device installed with a palm payment application and communicatively connected to the camera module, so that the terminal device further transmits the target palm image to a background server corresponding to the palm payment application, and completes a palm payment service through the background server to determine a target payment result corresponding to the target palm image.

[0208] It should be noted that the camera module in the embodiments of the present application only retains core hardware modules, such as an infrared and color camera for collecting image data, an image signal processor (ISP) for performing live body screening and / or optimization screening through a front-end algorithm, a communication module (such as a Bluetooth module) for establishing a communication connection with a terminal device, and a power module, etc. Compared with the special palm payment device in the related art, the configuration of the camera module is greatly simplified, and accordingly, the deployment cost is greatly reduced.

[0209] In addition, in the embodiments of the present application, since the live body screening and / or optimization screening algorithm is pre-positioned from the CPU to the neural network processor (NPU), the algorithm needs to be modified accordingly, using the data types and calculation operations supported by the NPU, reducing data transmission and memory access, and other optimization measures, and the interface between the NPU and other hardware (including data transmission and control signals, etc.) also needs to be redesigned.

[0210] The palm payment method provided by the embodiments of the present application uses a camera module and a terminal device installed with a palm payment application to replace the special palm payment device in the related art. Since the camera module used has a simple configuration, only relevant image collection devices and communication devices are included, and the palm payment application can be installed on any common terminal device in daily life, the deployment cost of the palm payment service is greatly reduced. When a merchant accesses the palm payment service, only a low-cost camera module needs to be deployed, and a palm payment application needs to be installed on a commonly used terminal device, without the need to deploy a high-cost special palm payment device. In this way, the convenience of the merchant accessing the palm payment service is improved, which is conducive to the popularization and promotion of the palm payment.

[0211] In a possible implementation manner, the camera module can transmit the target palm image to the terminal device installed with the palm payment application in the following manner:

[0212] The target palm image is encrypted to obtain encrypted image information; signature processing is performed based on the encrypted image information to obtain first signature information; a first encrypted message is generated according to the encrypted image information and the first signature information; and the first encrypted message is transmitted to the terminal device.

[0213] Specifically, in the embodiment of the present application, when the camera module transmits the target palm image to the terminal device, the target palm image needs to be encrypted. As introduced above, after the communication connection is established between the terminal device and the camera module, the public keys of each other can be exchanged, based on which the camera module can encrypt the target palm image by using the obtained public key of the terminal device (i.e. the first public key) to obtain encrypted image information; in order to ensure that the encrypted image information is not tampered with during transmission, the camera module can also generate first signature information based on the encrypted image information, for example, the corresponding hash value can be calculated based on the encrypted image information, and the first signature information is generated accordingly. Further, the camera module can add the above-mentioned encrypted image information and the first signature information to the first encrypted message, and send the first encrypted message to the terminal device.

[0214] After the terminal device receives the first encrypted message, the integrity of the encrypted image information therein can be verified based on the first signature information therein; specifically, the terminal device can calculate the first signature information based on the encrypted image information in the first encrypted message, and compare whether the calculated first signature information is consistent with the first signature information in the first encrypted message. If they are consistent, it can be determined that the encrypted image information has not been tampered with during transmission and has passed the integrity verification, at which time the terminal device can decrypt the encrypted image information by using its own private key (i.e. the first private key) to obtain the target palm image.

[0215] In this way, by the above-mentioned manner, the target palm image is transmitted to the terminal device based on the encryption and signature mechanism, which can ensure the integrity and confidentiality of the transmitted target palm image, thereby ensuring the security and reliability of the palm payment service and avoiding the target palm image being stolen during transmission.

[0216] Referring to Figure 6 , Figure 6 The flowchart of the palm payment method provided by the background server side of the embodiment of the present application is shown. As Figure 6 shown, the palm payment method comprises the following steps:

[0217] Step 601: receiving a target palm image transmitted by a terminal device installed with the palm payment application.

[0218] In the embodiment of the present application, the background server corresponding to the palm payment application can receive the target palm image transmitted by the terminal device installed with the palm payment application, so as to complete the palm payment service according to the received target palm image.

[0219] Step 602: According to the target palm image, the target object corresponding to the target palm image is searched.

[0220] After the background server receives the target palm image, the target object corresponding to the target palm image can be searched according to the target palm image, that is, the target object to which the palm in the target palm image belongs is searched.

[0221] As an example, the background server can extract features of the received target palm image through an image feature extraction model to obtain palm features corresponding to the target palm image. Then, the background server can search for palm features matching the palm features corresponding to the target palm image in the palm feature library, that is, search for palm features satisfying a preset similarity requirement between the palm features corresponding to the target palm image in the palm feature library; it should be understood that the palm feature library herein stores palm features of each user who has opened the palm payment function.

[0222] Of course, in actual application, the background server can also search for the corresponding target object according to the target palm image through other ways, and the embodiments of the present application do not limit the way of searching for the target object.

[0223] Step 603: If the target object is found, a payment operation is performed based on the payment account of the target object, and a target payment result representing the result corresponding to the payment operation is generated; if the target object is not found, a target payment result representing the failure of palm payment is generated.

[0224] If the background server finds the target object corresponding to the target palm image, the background server can further determine the payment account corresponding to the target object and deduct the corresponding amount from the payment account; it should be understood that the amount of money to be deducted herein can be provided by the terminal device installed with the palm payment application, that is, the terminal device can transmit the amount of money to be paid for this time of palm payment to the background server at the same time of transmitting the target palm image. If the deduction from the payment account is successful, a target payment result representing the success of palm payment can be generated; if the deduction from the payment account fails, for example, due to insufficient balance of the payment account, the payment account does not support direct deduction by the background server, etc., a target payment result representing the failure of palm payment can be generated.

[0225] If the target object corresponding to the target palm image is not found by the background server, the background server can directly generate a target payment result representing that the palm payment fails.

[0226] Step 604: returning the target payment result to the terminal device.

[0227] After the server generates the target payment result, the terminal device sending the target palm image can be fed back the target payment result correspondingly, so as to prompt the terminal device to the target payment result, and inform the merchant and the user triggering the palm payment whether the palm payment is successful this time.

[0228] The palm payment method provided by the embodiments of the present application uses the camera module and the terminal device installed with the palm payment application to replace the special palm payment device in the related art. Since the camera module used is simple in configuration, only the related image acquisition device and the communication device are included, and the palm payment application can be installed on any common terminal device in daily life, the deployment cost of the palm payment service is greatly reduced. When the merchant accesses the palm payment service, only the low-cost camera module needs to be deployed, and the palm payment application needs to be installed on the commonly used terminal device, without the need to deploy the high-cost special palm payment device. In this way, the convenience of the merchant accessing the palm payment service is improved, which is conducive to the popularization and promotion of the palm payment. In the palm payment service, the background server provides corresponding background support for the front-end palm payment service, finds the object corresponding to the palmprint image collected by the camera module, and completes the deduction from the payment account of the found object, so as to ensure that the palm payment service is stable and reliable.

[0229] In a possible implementation, the method provided by the embodiments of the present application further includes:

[0230] receiving the encrypted identity information sent by the terminal device installed with the palm payment application, the encrypted identity information being obtained by encrypting the identity information of the palm payment application and the identity information of the camera module establishing the communication connection with the terminal device; verifying the identity of the palm payment application and the identity of the camera module based on the encrypted identity information, obtaining an identity verification result, and returning the identity verification result to the terminal device. If the identity verification result represents that the identity verification of the camera module passes and the identity verification of the palm payment application passes, the terminal device installed with the palm payment application is recorded as a legal device supporting the palm payment service.

[0231] In the embodiments of the present application, after the terminal device installed with the palm payment application and the camera module establish a communication connection, but before formally accessing the palm payment service, the identity of the palm payment application installed on the terminal device and the identity of the camera module need to be verified by the background server, that is, whether the identity of the palm payment application is legal and whether the identity of the camera module is legal are verified, and after it is determined that the identity of the palm payment application and the identity of the camera module are both legal, the terminal device installed with the palm payment application and the camera module are allowed to formally access the palm payment service to collect and transmit palm images. The specific way of verifying the identity of the palm payment application and the identity of the camera module has been introduced above, and details can be referred to the related introduction content above.

[0232] In addition, after the background server determines that the identity of the palm payment application and the identity of the camera module are both legal, the terminal device installed with the palm payment application can be registered, that is, the terminal device is recorded as a legal device supporting the palm payment service. Specifically, the encrypted identity information transmitted by the terminal device to the background server can also carry the identity information of the terminal device itself, such as the product serial number (Serial Number, SN) of the terminal device, which can uniquely identify the identity of the terminal device; after the background server determines that the identity of the palm payment application installed on the terminal device is legal and the identity of the camera module establishing a communication connection with it is also legal, the identity information of the terminal device can be registered and managed to realize the registration record of the terminal device accessing the palm payment service. It should be understood that if the terminal device subsequently exits the palm payment service, the background server can also cancel the recorded identity information of the terminal device accordingly.

[0233] In this way, through the above-mentioned manner, before the terminal device installed with the palm payment application and the camera module jointly perform the palm payment service, the identity of the palm payment application in the terminal device and the identity of the camera module are verified by the background server, which ensures that the camera module accessing the palm payment service is a legal camera module, and ensures that the palm payment application accessing the palm payment service is a legal application, thereby providing security guarantee for subsequent palm payment service. In addition, in the above identity verification process, the identity information of the palm payment application and the identity information of the camera module are transmitted in an encrypted manner, which can avoid the identity information of the palm payment application and the identity information of the camera module being leaked, further improving the security of the entire identity verification process. In addition, after it is determined that the identity of the palm payment application and the identity of the camera module are both legal, the background server registers and manages the terminal device, which can realize the unified management of the terminal device accessing the palm payment service.

[0234] In a possible implementation manner, the method provided by the embodiments of the present application further comprises:

[0235] An association heartbeat is established with the palm payment application in the terminal device, and the association heartbeat is used to detect whether the palm payment application in the terminal device remains in a survival state. When it is detected that the association heartbeat is disconnected, prompt information is sent to the terminal device to prompt the terminal device to detect the running state of the palm payment application.

[0236] In the embodiment of the present application, after the terminal device installed with the palm payment application accesses the palm payment service, an association heartbeat can be established between the background server and the palm payment application in the terminal device. The association heartbeat may, for example, be a periodic signal sent by the palm payment application in the terminal device to the background server. The association heartbeat can help the background server to detect whether the palm payment application in the terminal device remains in a survival state.

[0237] When the background server detects that the association heartbeat is disconnected, for example, the background server does not receive the periodic signal sent by the palm payment application within a preset time interval, it can be considered that the association heartbeat between the background server and the palm payment application is disconnected. At this time, the background server can send prompt information to the terminal device, and the prompt information is used to prompt the terminal device to detect the running state of the palm payment application therein. After the terminal device receives the prompt information, it can correspondingly detect whether the palm payment application is in a survival state. If the palm payment application is not in a survival state, the palm payment application is restarted in time.

[0238] In this way, based on the association heartbeat between the background server and the palm payment application, and by means of the background server supervising whether the palm payment application in the terminal device is in a survival state, the palm payment service can be more effectively ensured to continuously and stably run, and the palm payment service is prevented from being interrupted, thereby avoiding negative experience for users.

[0239] In order to further understand the palm payment method provided by the embodiments of the present application, the following will be combined with Figure 7 and Figure 8 to make an exemplary overall introduction to the palm payment method provided by the embodiments of the present application.

[0240] Figure 7 The overall architecture of the palm payment method provided by the embodiments of the present application is shown in the figure. As shown in the figure, the palm payment method provided by the embodiments of the present application needs to be cooperatively implemented by a terminal device, a camera module and a background server. Figure 7

[0241] ​The terminal device is installed with a palm payment application, which includes a network module, a Bluetooth module, a floating window module and a resident module. The network module is used for communication with a background server, and transmits a target palm image sent by a camera module to the background server, and receives a target payment result returned by the background server. The Bluetooth module is used for communication with the camera module, and is used for receiving a target palm image sent by the camera module, and sending a control instruction to the camera module. The floating window module is used to create a floating window in the foreground of the terminal device, so as to display the target payment result fed back by the background server through the floating window. The resident module is used to control the process corresponding to the palm payment application to keep alive in the terminal device.

[0242] The camera module includes an ISP and a three-dimensional camera. The ISP is used to support the implementation of the front living body screening algorithm and the preferred screening algorithm. The three-dimensional camera includes an infrared camera and a color camera.

[0243] The background server is used to support the implementation of the palm recognition service, the basic payment service, the device management service and the abnormal strategy management service. The palm recognition service is used to identify a target object corresponding to a target palm image based on the target palm image sent by the terminal device. The basic payment service is used to complete the payment of the corresponding amount based on the payment account of the target object in the case of identifying the target object. The device management service is used to manage the terminal device accessing the palm payment service, and registers and manages the terminal device accessing the palm payment service. The abnormal strategy management service is used to establish an association heartbeat with the palm payment application in the terminal device, and detects whether the palm payment application in the terminal device is normally running based on the association heartbeat, so as to ensure the stable operation of the palm payment service.

[0244] Figure 8 The palm payment method provided by the embodiment of the application is provided. As shown in Figure 8 The merchant can install and start the palm payment application on the terminal device. After the palm payment application is started, it will automatically check the security of its running environment. If the obtained environment check result represents that the running environment is safe, the terminal device and the camera module can be controlled to establish a communication connection.

[0245] When the palm payment service is performed, the user can perform palm swiping against the camera module, and the camera module can collect multiple palm images of the user as base palm images. Then, the camera module can perform screening processing on the collected multiple base palm images through live body screening and optimization screening, to retain a base palm image corresponding to a live body palm and having better image quality as a target palm image. Further, the camera module can transmit the target palm image to a terminal device in communication connection therewith. After the terminal device receives the target palm image, the terminal device further transmits the target palm image to a background server corresponding to a palm payment application. After the background server receives the target palm image, the background server can search for a target object corresponding to the target palm image based on the target palm image, perform a corresponding deduction operation based on a payment account of the searched target object, further generate a target payment result corresponding to the palm payment, and return the target payment result to the terminal device. After the terminal device receives the target payment result, the terminal device correspondingly prompts the target payment result, to inform a merchant and a user triggering the palm payment whether the palm payment is successfully completed.
