[0045] Currently, before the actual application of the palm-sweeping application, the user needs to enable it on the terminal device before it can be used normally. And the enabling of the palm-sweeping application strongly depends on the network. In some situations where the network signal is poor, unstable, or even there is no network, for example, at bus stops on viaducts or in areas with weak signals in crowded subways, etc., it is easy to cause a poor enabling experience for users or a failure to enable, thereby resulting in user loss and a problem of poor user retention rate.

[0046] In view of the above problems, in the present application, a method, device, and related products for offline authorization to enable a palm-sweeping application are provided. The purpose is to solve the problem of users enabling the palm-sweeping application in the case of no network or weak network, improve the user's enabling experience, and increase the user retention rate. In the technical solution provided by the present application, the user terminal establishes a local connection with the palm-sweeping device for data interaction. The palm-sweeping device contains scene information, and the scene ticket is generated based on the scene information and the login identifier of the user terminal. Therefore, the user terminal can respond to the request of the palm-sweeping device to obtain palm feature information, and send the palm feature information to the corresponding palm-sweeping device according to the association relationship between the scene ticket and the palm feature information. Thus, without relying on the network, the authorization and enabling of the palm-sweeping application corresponding to the palm-sweeping device are completed, solving the problem of users enabling the palm-sweeping application in the case of no network or weak network, thereby improving the user's enabling experience, reducing user loss, and increasing the user retention rate.

[0047] First, several noun terms that may be involved in the following embodiments of the present application are explained.

[0048] Palm recognition: A technology that exchanges user identity information through palm multimedia information;

[0049] 3D camera: Analogous to a traditional camera, it adds software and hardware related to liveness, including a depth camera and an infrared camera, to ensure information security;

[0050] SN: String serial number (English: Serial Number, SN), which is used to uniquely identify the identification information (English: Identification, ID) of a device;

[0051] SQLite: A lightweight database, a relational database management system that complies with ACID. ACID refers to the key features in a database management system, including atomicity, consistency, isolation, and durability.

[0052] The execution subject of the method for offline authorization to enable the palm - swiping application provided in the embodiments of the present application can be a terminal device. For example, the first application on the user terminal can extract the palm features of the target object and associate the palm feature information with the user login identifier of the target object in the first application. After the user terminal establishes a local connection with the palm - swiping device, it receives the scene information of the palm - swiping device, generates a scene ticket based on the scene information and the user login identifier, and associates the scene ticket with the palm feature information. In response to the request of the palm - swiping device to obtain palm feature information, according to the association relationship between the scene ticket and the palm feature information, it sends the palm feature information to the palm - swiping device to indicate that the target object authorizes the opening of the palm - swiping application corresponding to the palm - swiping device. As an example, the terminal device may specifically include, but is not limited to, mobile phones, desktop computers, tablet computers, laptop computers, handheld computers, intelligent voice interaction devices, intelligent home appliances, vehicle terminals, aircraft, etc.

[0053] The execution subject of the method for offline authorization to enable the palm - swiping application provided in the embodiments of the present application can also be a server. It can extract the features of the palm image of the target object. After the user terminal corresponding to the server establishes a local connection with the palm - swiping device, in response to the request of the palm - swiping device to obtain palm feature information, according to the association relationship between the scene ticket and the palm feature information, it sends the palm feature information to the palm - swiping device to indicate that the target object authorizes the opening of the palm - swiping application corresponding to the palm - swiping device.

[0054] The execution subject of the method for offline authorization to enable the palm-sweeping application provided by the embodiments of the present application may also be a palm-sweeping device. After the palm-sweeping device establishes a local connection with the user terminal, the palm-sweeping device may send the scenario information of the palm-sweeping device to the user terminal, and then may send a request to obtain palm feature information to the user terminal, so that the user terminal sends the palm feature information to the palm-sweeping device, thereby receiving the palm feature information to instruct the target object to authorize the opening of the palm-sweeping application corresponding to the palm-sweeping device.

[0055] The method for offline authorization to enable the palm-sweeping application provided by the embodiments of the present application may also be executed collaboratively by the terminal device and the palm-sweeping device, or the server and the palm-sweeping device. For example, after the terminal device and the palm-sweeping device establish a local connection, data interaction is performed between the terminal device and the palm-sweeping device. When the palm-sweeping device receives the palm feature information sent by the user terminal, it means that the target object authorizes the opening of the palm-sweeping application corresponding to the palm-sweeping device. Therefore, in the embodiments of the present application, there is no limitation on the implementation subject for executing the technical solution of the present application.

[0056] Figure 1 An exemplary scenario architecture diagram of a method for offline authorization to enable the palm-sweeping application is shown. Figure 1 It includes that the palm-sweeping device and the portable terminal device establish a local connection through Bluetooth. Different from traditional card-sweeping devices, the palm-sweeping device uses palm recognition technology to verify the user's identity without relying on cards or passwords. The palm-sweeping device usually consists of a device with a high-resolution camera, and reference can be made to Figure 2 , Figure 2 which is a schematic diagram of palm recognition provided by the embodiments of the present application. The user only needs to place the palm above the induction area of the device, and the palm-sweeping device can read the palmprint image of the palm, and then complete the user's identity verification by comparing it with the palmprint image stored when the palm-sweeping device is opened, providing a convenient, efficient, and secure identity verification method through palm recognition technology. Or the palm-sweeping device can also perform data interaction with the server. The server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers. In addition, the server can also be a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms.

[0057] Figure 3 This is a flowchart of a method for offline authorization to enable the palm-sweeping application provided by the embodiments of the present application. As Figure 3 shown in the method, it includes:

[0058] S301: Extract features from the palm image of the target object through the first application of the user terminal to obtain palm feature information.

[0059] The user can take a picture of the user's palm through an application in the user terminal according to preset requirements. As an example, the preset requirements can be that the user needs to take the picture under high visibility to avoid a low visibility of the captured image, so that the palm image features cannot be extracted. Or, the preset requirements can also be that the user needs to capture the entire palm image to avoid too small a coverage area of the captured palm image, making it impossible to accurately extract features of the entire palm image, etc.

[0060] Since most of the cameras on user terminals are color cameras, the images captured based on the user terminal are color images, and single-factor recognition can be performed, so single-factor feature extraction can be carried out on the user's palm image. Single-factor recognition refers to a method of identity recognition and verification through a single factor. For example, feature extraction is performed through a single color element in a color image.

[0061] In a possible implementation manner, before performing feature extraction on the user's palm image, quality screening and liveness detection can be performed on the user's palm image, and then feature extraction is performed on the screened palm image. As an example, quality screening refers to comprehensively selecting the palm picture with the best quality through coefficient indicators such as palm size, angle, image contrast, image brightness, and clarity. Liveness detection is used to verify whether the palm information in the image is real, aiming to distinguish forged non-living palm images. For example, liveness detection of the palm image can be performed through texture analysis, light change analysis, and depth information analysis.

[0062] Single-factor feature extraction is performed on the screened palm image. After feature extraction, the original captured image can be deleted, and the obtained palm feature information is used for subsequent comparison and recognition.

[0063] S302: Associate the palm feature information with the user login identifier of the target object in the first application.

[0064] The user login identifier of the first application can be a login ticket token. Since the embodiments of this application are related to offline applications based on terminal devices in a no-network or weak-network situation, after obtaining the feature information of the palm, the login ticket of the first application can be further obtained, and the login ticket is uniquely associated with the palm feature information, so that the palm feature information is uniquely associated with the user's login identity information. The login identity information of a user uniquely corresponds to a palm feature information. Among them, the login ticket token in the application program is an access token issued by the application program open platform, which is used to verify the user's identity information and implement the access authorization of the user in the third-party application. When the user selects to log in with the identity of the first application in the third-party application, the third-party application will guide the user to enter the authorization page of the first application. After the authorization is successful, the first application will return an access token, that is, the login ticket token, to the third-party application. That is to say, the embodiments of this application are equivalent to a third-party application or a small program in the first application. Log in to the third-party application with the identity of the first application. After obtaining the feature information of the palm, obtain the login ticket of the first application, so as to associate the token with the palm feature information.

[0065] S303: After the user terminal establishes a local connection with the palm brushing device, receive the scene information of the palm brushing device.

[0066] In a possible implementation manner, the user needs to first authorize the local connection request of the palm brushing device on the terminal device to allow receiving local connection access from the palm brushing device, so as to establish a connection relationship with the palm brushing device and perform data interaction. As an example, the local connection methods include Bluetooth connection, local area network connection, wifi direct connection (Wireless Fidelity Direct, wifi-Direct) or connection through the Universal Serial Bus (USB).

[0067] In a possible implementation manner, after the user authorizes the local connection request of the palm brushing device, it means that the user terminal allows receiving local connection access from the palm brushing device. The user terminal receives the connection request of the palm brushing device and can authenticate the palm brushing device. Only when the verification result is passed, it means that the user terminal successfully establishes a local connection with the palm brushing device.

[0068] As an example, secure communication can be implemented based on Bluetooth. The security mode of Bluetooth can be used to establish a secure connection between the user terminal and the palm brushing device. For example, the authentication mode is used, that is, the authentication of the palm brushing device mentioned above. Before establishing a local connection, the two devices need to authenticate each other, and encrypted communication can also be maintained during the connection.

[0069] For example, the authentication process includes the palm brushing device sending a connection request to the user terminal. After receiving the connection request, the user terminal generates a random number and sends the generated random number to the palm brushing device. After receiving the random number sent by the user terminal, the palm brushing device can use a pre-shared key, that is, the key agreed upon by the palm brushing device and the user terminal, to encrypt the random number, thereby obtaining an encrypted result and sending the encrypted result to the user terminal. After receiving the encrypted result sent by the palm brushing device, the user terminal can use the agreed key to decrypt the encrypted result, thereby obtaining a decrypted result. The decrypted result is compared with the generated random number. If the two random numbers are the same, it means that both have successfully passed the authentication and a local connection can be successfully established. Or, the authentication process can also include that after the two random numbers match successfully, the user terminal can also send a confirmation message to the palm brushing device. After receiving the confirmation message sent by the user terminal, the palm brushing device will send a similar confirmation message to the user terminal. If the user terminal receives the confirmation message sent by the palm brushing device and the two random numbers match successfully, it means that the user terminal and the palm brushing device have successfully established a local connection.

[0070] After the user authorizes the local connection request of the palm brushing device, when the user approaches the palm brushing device with a terminal device in a no-network or weak-network state, after the local connection request passes, it means that the terminal device and the palm brushing device have successfully established a local connection, enabling secure data interaction between the two subsequently.

[0071] In addition, during the interaction between the user terminal and the palm brushing device, an encryption algorithm can be used to encrypt the communication. For example, the Advanced Encryption Standard (AES), a symmetric encryption algorithm, is used to encrypt the data, thereby transmitting encrypted data during the interaction. Through this authentication method and encrypted communication method, it can be ensured that the data is secure during transmission and cannot be accessed by unauthorized devices, further enhancing the security of data interaction.

[0072] Therefore, after the user terminal and the palm brushing device successfully establish a local connection, the user terminal can receive the scene information sent by the palm brushing device, and thus can associate the scene information with the palm feature information. The scene information of the palm brushing device refers to the information used to identify the scene where the palm brushing device is located. For example, the ID code of the palm brushing device in different scenes, or the SN code of the palm brushing device. Since the palm brushing device can be deployed on buses, convenience stores, subway stations, and access control systems, the ID codes of the palm brushing devices in different scenes are different. For example, the ID code of the palm brushing device may contain coordinate information in a specific area.

[0073] S304: Generate a scene ticket based on the scene information and the user login identifier, and associate the scene ticket with the palm feature information according to the association relationship between the user login identifier and the palm feature information.

[0074] In a possible implementation manner, the scene information of the palm brushing device and the user login identifier can be input into a random number generator (RNG for short), so as to generate a scene ticket scene_palm_token. The scene ticket is a randomly generated string. The random number generator is a program or device for generating random numbers. For example, the random number generator MT19937 or SHA-256. Inputting the scene ID of the palm brushing device and the login token into the random number generator, enough random bytes can be obtained from the random number generator to generate a random string of a specified length, and then the string can be converted into the required character set. For example, Base64 encoding can be used for conversion. Thus, a randomly generated, one-time scene ticket that can only be applied to the one-time request of the feature can be obtained, and the scene ticket also includes timeliness information. For example, the scene ticket has an expiration time, and the scene ticket can only be used for palm recognition within a specific time period, which improves the security of the palm brushing recognition process. Since the scene ticket is generated based on the scene information, the use of the scene is restricted, further ensuring the security of authorization in the offline scene.

[0075] Since the palm feature information is associated with the user login identifier, the scene ticket and the palm feature information can be associated according to the association relationship between the login ticket and the palm feature information. Associating the scene ticket and the palm feature information together restricts the application scenario of the palm feature information, thus ensuring the security of authorization in the offline scene.

[0076] In addition, the user terminal can also store the palm feature information, the association relationship between the login ticket and the palm feature information, and the association relationship between the scene ticket and the palm feature information in an encrypted database.

[0077] As an example, taking the terminal device as an Android system, SQLite database can be used to store data, and the following components can also be used to ensure secure storage. Of course, the embodiments of the present application are not limited to the Android system, and can also be an iOS system, etc. The present application does not specifically limit the application system.

[0078] In a possible implementation, the SQLite database can encrypt the database using an encryption algorithm. The encryption function can be implemented through the SQLCipher library for encrypted databases provided by the Android system to protect data confidentiality. Thus, the palm feature information, the association relationship between the login ticket and the palm feature information, and the association relationship between the scenario ticket and the palm feature information can be stored in the encrypted database.

[0079] In addition, the encrypted database can also use the ContentProvider component provided by the Android system to perform access control on the SQLite database. Through the ContentProvider component, access permissions can be set to ensure that only authorized applications can access the database. The SharedPreferences data storage component provided by the Android system can also be used to store sensitive data. Through the SharedPreferences component, the data in the database can be encrypted and stored. To prevent data loss, the Backup API data backup mechanism provided by the Android system can be used to back up the SQLite database. The backup data can be stored in the cloud to ensure that the data stored in the database can be restored even if the device is damaged or lost. Finally, to prevent the code from being exploited by attackers, secure coding practices can also be used to write the application. For example, parameterized queries are used instead of string concatenation to execute Structured Query Language (SQL) queries to avoid injection attacks in SQL query statements.

[0080] Therefore, the encrypted database in the embodiments of the present application has functions of access control, encrypted data storage, and backup. By storing the palm feature information, the association relationship between the login ticket and the palm feature information, and the association relationship between the scenario ticket and the palm feature information in the encrypted database, the security and integrity of the stored data can be ensured.

[0081] S305: In response to a request from the palm brushing device to obtain palm feature information, send the palm feature information to the palm brushing device according to the association relationship between the scenario ticket and the palm feature information to instruct the target object to authorize the activation of the palm brushing application corresponding to the palm brushing device.

[0082] When the palm-sweeping device sends a request to the user terminal to obtain palm feature information, the user terminal can send the corresponding palm feature information to the palm-sweeping device based on the association relationship between the scene ticket and the palm feature information, thus completing the user authorization to activate the palm-sweeping application corresponding to the palm-sweeping device. Since the palm-sweeping device contains the scene information where the current device is located, that is, the scene ID of the palm-sweeping device, and the scene ticket is generated based on the scene code and the login ticket, and there is an association relationship between the scene ticket and the palm feature information, therefore, the user terminal can send the corresponding palm feature information to the palm-sweeping device based on the association relationship between the scene ticket and the palm feature information, improving the security of authorization in the offline scenario. The palm-sweeping application corresponding to the palm-sweeping device refers to the application program associated with the palm-sweeping device, which is used for identity verification in different scenarios. For example, the payment system corresponding to the palm-sweeping device or the access control system corresponding to the palm-sweeping device, etc.

[0083] for reference Figure 4 , Figure 4 FIG. Figure 4 is a schematic diagram of an offline authorization to activate a palm-sweeping application provided by an embodiment of the present application. First, the user terminal can take a picture of the user's palm, and then the user terminal can perform quality screening on the palm image and extract features from the palm image after quality screening to obtain palm feature information. After associating the palm feature information with the login ticket, the user terminal can then return a notification message indicating successful association to the user. The user terminal establishes a local connection with the palm-sweeping device terminal. The palm-sweeping device terminal sends scene information to the user terminal. The user terminal generates a scene ticket based on the scene information and the login ticket, and associates the scene ticket and the palm feature information. Then, in response to the request from the palm-sweeping device terminal to obtain palm feature information, according to the association relationship between the scene ticket and the palm feature information, the user terminal sends the corresponding palm feature information to the palm-sweeping device terminal to indicate that the user authorizes to activate the palm-sweeping application corresponding to the palm-sweeping device terminal. Finally, the palm-sweeping device terminal can return a notification message indicating successful authorization to activate the palm-sweeping application to the user terminal.

[0084] In a possible implementation manner, after the authorization activation is completed, the user terminal can receive a notification message indicating successful completion of the authorization activation. Subsequently, the palm-sweeping device can also store the received palm feature information locally in the palm-sweeping device, so that when the user performs palm-sweeping recognition, the palm-sweeping device can directly compare and identify the palm feature information collected on-site with the local palm feature information, thereby completing the use of the palm-sweeping application without relying on the network, improving the user experience.

[0085] The palm of the user is photographed through a terminal, and the obtained palm image is a color picture. The feature extraction process is single-factor feature extraction, and subsequent palm recognition is performed based on the palm feature information obtained from the single-factor feature extraction. In the embodiments of the present application, in order to further improve the accuracy of the palm recognition process, palm recognition can be performed based on the palm feature information and the user's credit rating.

[0086] In a possible implementation manner, the palm feature information collected on-site can be recognized based on the palm feature information and the user's credit rating. In response to a request from the palm brushing device to obtain the user's credit rating, the user's credit rating can be queried based on the user login identifier, that is, the login ticket. Since the login ticket refers to the user's login identity information, the user's credit rating can be queried based on the user's login ticket. Then, the user's credit rating can be sent to the palm brushing device, so that the palm brushing device can recognize the palm feature information collected on-site based on the palm feature information and the user's credit rating, further improving the accuracy of the palm recognition process.

[0087] As an example, the credit rating can be reflected in the form of a credit score. The user's credit rating is 30 points, that is, the user's credit rating is relatively low. When the current application scenario of the palm brushing device is large-amount payment, even if the palm feature information collected on-site is compared and recognized through the palm feature, and the recognition result is successful, the use function of the palm brushing application is not enabled for the current user based on the current user's credit rating. By adding the palm recognition method of the user's credit rating, the application types in the offline scenario are restricted, the accuracy of the palm recognition process is improved, and the security of the palm brushing application is ensured.

[0088] See Figure 5 , Figure 5 FIG. is a schematic structural diagram of an offline authorization to enable a palm brushing application provided by an embodiment of the present application, which mainly includes an application program backend service, an application program, and a palm brushing application program provided by an embodiment of the present application. The application program is mainly reflected through a user terminal. The application program mainly includes a terminal 2D camera, a mini-program module, a ticket association module, a palm feature extraction service, a database (English: Database, DB), and a login state module. The mini-program module refers to a palm brushing application provided by an embodiment of the present application that can be reflected in the application program in the form of a mini-program. The ticket association module is used to record the association relationship between the palm feature information and the login ticket, and the association relationship between the palm feature information and the scenario ticket. The database is used to store the palm feature information. The palm feature extraction service is used to extract features from the palm image. The login state module is used to record the user's login state and permissions.

[0089] The offline palm-sweeping device terminal and the 3D camera constitute the hardware part corresponding to the palm-sweeping application program. The palm-sweeping application program includes a palm-sweeping collection and recognition module, a temporary ticket verification module, a database, and a result page module. The palm-sweeping collection and recognition module can be used to collect the palm feature information of users on-site and can also be used for palm recognition. The temporary ticket verification module is used to upload the scene tickets with timeliness requirements to the backend service for verification. The result page module is used to display and record the recognition results of palm-sweeping recognition. The database is used to record the palm feature information collected on-site, the received palm feature information, and the recognition results of palm-sweeping recognition.

[0090] The application program backend service can include a palm update service, a palm service, a database, a payment service, and a temporary ticket verification service. The palm update service is used to update the palm feature information, including updating the infrared palm feature information. The palm service is used to record all the processing processes related to the palm feature information in the application program and the palm-sweeping application program. The database is used to record the data related to the application program backend service. The payment service is used to record the data related to the palm feature information in the payment state. The temporary ticket verification service is used to verify the scene tickets with timeliness requirements uploaded by the palm-sweeping application program.

[0091] The embodiment of the present application provides an offline authorization method for opening a palm-sweeping application. In this method, after extracting the feature of the palm image of the target object through the first application of the user terminal and obtaining the palm feature information, first associate the palm feature information with the user login identifier of the target object in the first application. Then, after the user terminal establishes a local connection with the palm-sweeping device, generate a scene ticket according to the received scene information of the palm-sweeping device and the user login identifier, and associate the scene ticket with the palm feature information according to the association relationship between the user login identifier and the palm feature information. Finally, in response to the request of the palm-sweeping device to obtain the palm feature information, the palm feature information can be sent to the palm-sweeping device according to the association relationship between the scene ticket and the palm feature information, so as to indicate that the target object authorizes to open the palm-sweeping application corresponding to the palm-sweeping device.

[0092] It can be seen that since the user terminal establishes a local connection with the palm-sweeping device, the palm-sweeping device contains scene information, and the scene ticket is generated based on the scene information and the login identifier of the user terminal. Therefore, when the palm-sweeping device sends a request to the user terminal to obtain the palm feature information, the user terminal can respond to the acquisition request of the palm-sweeping device and send the palm feature information to the corresponding palm-sweeping device according to the association relationship between the scene ticket and the palm feature information. Thus, without relying on the network, the authorization to open the palm-sweeping application corresponding to the palm-sweeping device is completed, solving the problem of users opening the palm-sweeping application in the case of no network or weak network, thereby improving the user's opening experience, reducing user churn, and increasing user retention rate.

[0093] See Figure 6 , Figure 6 which is a flowchart of another method for offline authorization to enable the palm-sweeping application provided by an embodiment of this application.

[0094] In Figure 6 the offline authorization method for enabling the palm-sweeping application described above, this method is applied to a palm-sweeping device and includes:

[0095] S601: After the palm-sweeping device establishes a local connection with the user terminal, send the scene information of the palm-sweeping device to the user terminal.

[0096] The palm-sweeping device sends the scene information of the current device to the user terminal, enabling the user terminal to generate a scene ticket based on the scene information, and then associate the palm feature information with the scene ticket according to the association relationship between the login ticket and the palm feature information. The palm feature information is obtained by the user terminal extracting features from the user's palm image.

[0097] S602: Send a request to obtain the palm feature information to the user terminal, so that the user terminal sends the palm feature information to the palm-sweeping device according to the association relationship between the scene ticket and the palm feature information.

[0098] S603: Receive the palm feature information sent by the user terminal to indicate that the target object authorizes the opening of the palm-sweeping application corresponding to the palm-sweeping device.

[0099] When the palm-sweeping device receives the palm feature information sent by the user terminal, it means that the user authorizes the opening of the palm-sweeping application corresponding to the current palm-sweeping device.

[0100] In a possible implementation manner, after the authorization to enable the palm-sweeping application is completed, a notification message indicating successful completion of the authorization can be sent to the user terminal. When the user performs palm-sweeping recognition on the current palm-sweeping device, the 2D camera of the palm-sweeping device can collect the current streaming media data of the user, that is, the video image of the user's palm. Then, quality screening can be performed on each frame of the video image of the palm. The optimal palm image, that is, the screened palm image, can be comprehensively selected through coefficient indicators such as palm size, angle, image contrast, image brightness, and clarity. After that, feature extraction can be performed on the screened palm image to obtain the palm feature information collected on-site by the user. Finally, the palm feature information collected on-site can be retrieved in the database to confirm the user's identity, that is, the palm feature information collected on-site can be compared and recognized with the palm feature information stored locally in the palm-sweeping device to obtain the recognition result. Based on the recognition result, the user's identity can be confirmed, so that the use of the palm-sweeping application can be realized in the case of no network or weak network.

[0101] In a possible implementation, the palm feature information collected on-site can be identified based on the palm feature information and the user's credit rating. The palm-scanning device sends a request to the user terminal to obtain the user's credit rating, enabling the user terminal to query the user's credit rating based on the login ticket. Since the login ticket refers to the user's login identity information, the user's credit rating can be queried based on the user's login ticket. Then, the palm-scanning device can receive the user's credit rating and identify the palm feature information collected on-site based on the palm feature information and the user's credit rating, improving the accuracy of the palm recognition process.

[0102] In addition, when the recognition result of palm recognition is successful, it means that the palm feature information collected on-site is the same as the palm feature information stored locally in the palm-scanning device, and the corresponding palm-scanning application of the palm-scanning device can be used. Since the feature extraction of the palm image by the user terminal is single-factor feature extraction, and the user has successfully authorized to activate and use the palm-scanning application, that is, the user has enabled it on the palm-scanning device and has the relevant information of the infrared image. Therefore, the infrared information corresponding to the palm image can be further supplemented, and the feature extraction of two factors is performed to increase the security and accuracy of palm-scanning recognition, effectively ensuring the security of palm-scanning recognition.

[0103] In a possible implementation, the infrared palm information of the user can be collected by the 3D camera of the palm-scanning device, and the infrared palm information and the corresponding palm feature information can be combined, that is, the infrared palm information and the palm feature information obtained by single-factor feature extraction before can be combined to obtain the infrared palm feature information.

[0104] Therefore, subsequent palm recognition can be based on the infrared palm feature information. Since it is necessary to compare and identify with the infrared palm information collected on-site, the infrared palm feature information collected next time on-site needs to be obtained by photographing the user's palm with the 3D camera to obtain the user's infrared palm information. Then, after the quality screening of the user's infrared palm information, the two-factor feature extraction is performed on the infrared palm information after quality screening to obtain the infrared palm feature information collected on-site. Therefore, only the first palm-scanning recognition is single-factor recognition, and the subsequent recognition process is two-factor recognition, effectively ensuring the security of palm-scanning recognition.

[0105] Moreover, when the user terminal is connected to the network, the current authorized scenario information can be synchronized to the cloud, that is, the association relationship between the scenario ticket and the palm feature information can be synchronized to the cloud. Since the scenario ticket is generated based on the scenario information of the palm brushing device, it is possible to clearly know the scenario when the user previously authorized the opening of the palm brushing application in the offline state. Since the user's palm feature information is associated with the scenario ticket, and the infrared palm feature information is generated based on the palm feature information, the infrared palm feature information is also associated with the scenario ticket. Therefore, the infrared palm feature information in the current authorized scenario can also be sent back to the cloud for storage, thus ensuring the security of the data in the authorized scenario.

[0106] After that, the synchronization result can also be sent to the palm brushing device. When the synchronization result is successful, in the subsequent palm recognition process, the infrared palm feature information collected on-site by the user can be recognized based on the infrared palm information, thereby improving the accuracy of palm recognition.

[0107] Since the scenario ticket contains timeliness information that can be used in the verification process of palm brushing recognition, reference can be made to Figure 7 , Figure 7 which is a schematic diagram of palm brushing recognition provided by an embodiment of the present application. The application type of the offline scenario of the palm brushing device can be extended based on the scenario ticket. For example, it can be applied to an access control system, or the ID information of the relevant user can be queried through the scenario ticket.

[0108] First, the user terminal establishes a local connection with the palm brushing device terminal. The palm brushing device terminal sends scenario information to the user terminal. The user terminal generates a scenario ticket based on the scenario information and the login ticket, and associates the scenario ticket with the palm feature information. Then, in response to the request of the palm brushing device terminal to obtain the palm feature information, according to the association relationship between the scenario ticket and the palm feature information, the corresponding palm feature information is sent to the palm brushing device terminal to indicate that the user authorizes the opening of the corresponding palm brushing application on the palm brushing device terminal. Finally, the palm brushing device terminal can return a notification message to the user terminal indicating successful authorization to open the palm brushing application.

[0109] Thus, the authorization to activate the palm-sweeping application is completed. Then, when the user conducts palm-sweeping recognition on the palm-sweeping device, the palm feature information stored locally on the palm-sweeping device can be used to identify with the palm feature information collected on-site, and based on the association relationship between the palm feature information and the scene ticket, the scene ticket can be obtained. Since the scene ticket contains timeliness information, for example, the valid duration of the scene ticket is 5 minutes. Therefore, the scene ticket can be sent to the application backend for verification. The application backend can verify the valid duration of the obtained scene ticket. If the obtained scene ticket is within the valid period, it indicates successful verification; if the obtained scene ticket is not within the valid period, it indicates failed verification. The application backend can return the verification result to the palm-sweeping device, then the palm-sweeping device returns it to the user terminal, and finally to the target object. Finally, after connecting to the network, the user terminal can also re-upload the infrared palm feature information and the association relationship between the scene ticket and the palm feature information to the application backend for storage, and the application backend can return the upload result indicating whether the upload is successful.

[0110] Thus, palm-sweeping recognition can be performed through the scene ticket. Since the scene ticket contains the scene information of the palm-sweeping device and adds a time limit, the security of palm-sweeping recognition is improved.

[0111] The embodiment of the present application provides another method for offline authorization to activate the palm-sweeping application. In this method, after the palm-sweeping device establishes a local connection with the user terminal, it can send the scene information of the palm-sweeping device to the user terminal. The scene information of the palm-sweeping device is used to generate a scene ticket with the user login identifier. The scene ticket is used to associate with the palm feature information according to the association relationship between the user login identifier and the palm feature information. The palm feature information is obtained by the user terminal through feature extraction of the palm image of the target object. It can also send a request to obtain the palm feature information to the user terminal, so that the user terminal can send the palm feature information to the palm-sweeping device according to the association relationship between the scene ticket and the palm feature information. Receive the palm feature information sent by the user terminal to indicate that the target object authorizes the activation of the palm-sweeping application corresponding to the palm-sweeping device.

[0112] It can be seen that since the user terminal establishes a local connection with the palm-sweeping device, the palm-sweeping device contains scene information, and the scene ticket is generated based on the scene information and the login identifier of the user terminal. Therefore, when the palm-sweeping device sends a request to obtain the palm feature information to the user terminal, the user terminal can respond to the acquisition request of the palm-sweeping device and send the palm feature information to the corresponding palm-sweeping device according to the association relationship between the scene ticket and the palm feature information. Thus, without relying on the network, the authorization to activate the palm-sweeping application corresponding to the palm-sweeping device is completed, solving the problem of users activating the palm-sweeping application in the case of no network or weak network, thereby improving the user's activation experience, reducing user churn, and increasing user retention rate.
