[0066] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0067] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties.

[0068] The identification code generation method and identification code processing method provided in this application can be applied to Figure 1 In the application environment shown, a user displays an identification code through a payment terminal 102, and a payment terminal 104 scans the identification code displayed on the payment terminal 102, thereby obtaining identification code scan information. When generating an identification code, the payment terminal 102: obtains an identification code generation instruction, which instructs the generation of an identification code; if the offline code generation conditions are met, obtains a locally cached generation element; the generation element is obtained by updating a historical generation element based on the latest push message, which is a message proactively pushed by the server 106 after the current user completes the previous payment; and generates an identification code based on the generation element. After scanning the identification code scan information, the payment terminal 102 performs a validity check on the identification code scan information and, if the validity check passes, initiates payment based on the identification code scan information. The payment terminal 102 may be, but is not limited to, various personal computers, laptops, smartphones, tablet computers, and portable wearable devices. The payment terminal 104 may be an electronic device equipped with a code scanning function, such as a personal computer equipped with a code scanning function, or a ticket gate, gate machine, etc.

[0069] In one embodiment, Figure 2 As shown, a method for generating an identification code is provided, which is applied to Figure 1 The payment terminal in the example is used to illustrate the following steps:

[0070] Step S201: Obtain an identification code generation instruction.

[0071] The identification code generation instruction is used to instruct the generation of an identification code. The identification code is a coding method that can be identified by scanning. The specific type of the identification code is not unique, such as a QR code or a barcode.

[0072] Specifically, the user can open the mobile payment client installed on the payment terminal and click on the corresponding location in the mobile payment client interface to generate an identification code generation instruction. For example, when using WeChat or Alipay to make a payment, when clicking "Payment", the user issues the identification code generation instruction, and the payment terminal receives the identification code generation instruction.

[0073] It should be noted that the mobile payment client can also be a specific industry application mobile payment program dedicated to various types of enterprises and industries such as government affairs, transportation and logistics, police, tobacco, medical care, education or sports. Due to the single function of these industry application mobile payment programs, users usually only open them when they need to use them, and they may be used offline. For example, a subway app (application software) dedicated to taking the subway and a campus app dedicated to school cafeteria consumption will only be opened when needed, such as when eating in the cafeteria or entering the subway. There may be no network when needed, and even if there is a network, the application has not been opened. As a result, the payment terminal cannot generate an identification code, or the user status information in the identification code is incorrect, affecting the reliability and security of mobile payment.

[0074] Step S202: If the offline code generation condition is met, obtain the generation elements cached locally.

[0075] The "offline code" refers to an identification code that can be generated offline. Correspondingly, the offline code generation condition requires the payment terminal to be disconnected from the internet, meaning the network signal strength at the payment terminal is less than a preset signal threshold. Furthermore, generation factors include user name information, user status information, balance information, identification code validity period information, and key information. These generation factors are obtained by updating historical generation factors based on the latest push message. The latest push message is a message proactively pushed by the server after the current user's last payment is completed. The specific type of the latest push message is not unique; for example, it can be a broadcast message or a short message.

[0076] Specifically, after the current user completes the last payment, the server updates the status information corresponding to the current user based on the current user's payment status, obtains the latest user information, and generates a push message based on the latest user information and pushes it to the payment terminal. It can be understood that the user information contains the payment terminal identifier to ensure that the server can achieve targeted and accurate push of push messages. Furthermore, the payment terminal receives the latest push message, extracts the feature information related to the generation factor in the latest push message, and updates the historical generation factor based on this feature information to obtain the updated generation factor. In this way, when the offline code generation conditions are met, the generation factor directly obtained by the payment terminal from the local cache is the latest generation factor that matches the latest status information corresponding to the current user.

[0077] In addition, before using the offline code generation function of the mobile payment client, the user must also register for the offline code generation function. Specifically, when the user is online, he or she can enter the user information by operating the corresponding interface in the mobile payment client to activate the offline code generation function. This user information, including but not limited to user device information, user personal information, payment account information, etc., is verified by the server corresponding to the mobile payment client. If the verification is passed, the registration is successful. If the registration is successful, the server will synchronously save this user information and update the user information accordingly after each payment is completed. When the offline code generation conditions are not met, the payment terminal requests the server to generate elements. The server obtains the generation elements based on the user information stored on the server and sends them to the payment terminal.

[0078] Step S203: Generate an identification code according to the generation elements.

[0079] Specifically, the identification code can be generated according to the generation factor and a specific encoding method. The scanning terminal can obtain the identification code scanning information corresponding to the generation factor by scanning the identification code.

[0080] In the above-mentioned identification code generation method, on the one hand, the payment terminal generates the identification code based on the locally cached generation factors, that is, the payment terminal can also generate the identification code in an offline state, thereby realizing mobile payment, which is conducive to expanding the application scenarios of the mobile payment method; on the other hand, since the generation factors are obtained by updating the historical generation factors based on the latest push message, the production factors used by the payment terminal to generate the identification code correspond to the latest user status information, which can avoid the user status information contained in the identification code from being incorrect, and is conducive to improving the reliability and security of mobile payment.

[0081] As mentioned above, the payment terminal needs to update the historical generation factors based on the latest push message to obtain the generation factors, but the specific timing for updating the generation factors is not unique.

[0082] In one embodiment, the payment terminal updates the generation factors after obtaining the identification code generation instruction, that is, step S202 includes: if the offline code generation conditions are met and the local cache has the latest push message in a valid state, updating the historical generation factors according to the latest push message to obtain the locally cached generation factors.

[0083] The latest push message in a valid state refers to the push message with the push time closest to the current time and has not been used to update the generation factor. Specifically, if the offline code generation conditions are met, the payment terminal reads the locally cached push messages, filters the latest push message based on the push time, and determines whether the latest push message is valid. If so, the historical generation factor is updated based on the latest push message to obtain the locally cached generation factor. If not, no update is required and the locally cached generation factor is directly obtained. Furthermore, after updating the historical generation factor based on the latest push message, the status information of the latest push message is modified to invalid.

[0084] In another embodiment, after the payment is completed based on the current identification code, the payment terminal updates the generation element so as to be used to generate the identification code required for the next payment. Figure 3 As shown, after step S203, step S204 and step S205 are also included.

[0085] Step S204: Obtain the message that the server actively pushes after the payment based on the identification code is completed.

[0086] The message actively pushed by the server after the payment based on the identification code is completed can be a broadcast message or a short message. When the message actively pushed by the server is a broadcast message, the payment terminal automatically receives the push message as long as it is connected to the network, that is, the network signal strength is greater than a preset signal threshold, completing the process of obtaining the message actively pushed by the server. Short messages are messages transmitted via a specific SMS channel, and their reception does not require internet access. When the message actively pushed by the server is a short message, the payment terminal automatically receives the push message, regardless of whether it is connected to the network or offline, as long as the SMS channel provided by the corresponding operator is available, completing the process of obtaining the message actively pushed by the server.

[0087] Step S205: updating the locally cached generation elements according to the actively pushed message.

[0088] As mentioned above, the message actively pushed by the server is generated based on the latest user information obtained by the server based on the payment status of the current user and the latest user information updated by the server. Therefore, the push message contains the user information corresponding to the payment terminal. This user information includes but is not limited to user device information, user personal information, payment account information, etc. Among them, user device information includes payment terminal identification, user personal information includes user name information and user status information, and payment account information includes balance information and key information, etc. Specifically, the payment terminal receives the latest push message, extracts the feature information related to the generation element in the latest push message, and based on the feature information, updates the locally cached generation element to obtain the updated generation element that matches the latest user status information, which is used to generate the identification code required for the next payment.

[0089] In the above embodiment, two different generation factor update timings are provided, which is beneficial to improving the flexibility of the identification code generation method.

[0090] In one embodiment, the historical generation element includes an element type and corresponding type parameters; the latest push message is a short message whose sending platform identifier is a specified platform identifier and contains the element type and corresponding type parameters. The element type includes user name, user status, balance, identification code validity period, and identification code generation seed. The sending platform identifier is the platform identifier of the server corresponding to the mobile payment client. Since short messages are transmitted through a specific SMS channel, the reception of short messages does not require Internet support. Therefore, the payment terminal can receive short messages even when it is off-network, which can further ensure that the payment terminal can obtain the latest push messages in a timely manner and update the generation elements based on the latest push messages.

[0091] Furthermore, in one embodiment, Figure 4 As shown, the updated method for obtaining generated elements includes:

[0092] Step S401: Acquire a short message whose sending platform identifier is a designated platform identifier.

[0093] As described above, the sending platform identifier is the platform identifier of the server corresponding to the mobile payment client. Specifically, based on the designated platform identifier, the short messages cached locally are filtered to select the short messages whose sending platform identifier is the designated platform identifier.

[0094] Step S402: extracting the type parameter corresponding to the element type in the short message.

[0095] Element types include user name, user status, balance, identification code validity period, and identification code generation seed. Corresponding type parameters include user name information, user status information, balance information, identification code validity period, and key information. Specifically, the payment terminal reads the field information in the short message and, based on the specific field information, extracts the type parameter corresponding to the element type in the short message. For example, the field following the "user name" field is the user name information, and the field following the "balance" field is the balance information.

[0096] Step S403: Based on the type parameters corresponding to the element type, the type parameters corresponding to the element type in the historical generated element are updated to obtain the generated element.

[0097] Specifically, the type parameters of the historical generated elements are updated based on the type parameters corresponding to the extracted feature types to obtain the latest generated elements. It is understood that, in a similar manner, the type parameters corresponding to the feature types in the locally cached generated elements can also be updated based on the type parameters corresponding to the feature types to obtain updated generated elements.

[0098] In the above embodiment, a process for updating the generation elements when the latest push message is a short message is provided, which can ensure that the generation elements used to generate the identification code are generation elements that match the user's latest status information, which is conducive to improving the accuracy of the identification code and thereby enhancing the security of mobile payment.

[0099] In one embodiment, Figure 5 As shown, a method for processing an identification code is provided, which is applied to Figure 1 The payment terminal in the example is used to illustrate the process, which includes the following steps:

[0100] Step S501: Obtain identification code scanning information.

[0101] The identification code is a code that can be scanned and identified, such as a QR code or barcode. The identification code scan information is information obtained by scanning the displayed identification code. This information can be an image containing the identification code or text containing the generation elements corresponding to the identification code. If the identification code scan information is an image containing the identification code, the payment terminal can analyze the identification code and extract the generation elements used to generate the identification code from the identification code scan information.

[0102] Furthermore, the displayed identification code is generated by the payment terminal based on the generation factors cached locally, provided that the offline code generation conditions are met. The generation factors are obtained by updating the historical generation factors based on the latest push message, which is the message proactively pushed by the server after the current user's last payment is completed.

[0103] Step S502: Perform a validity check on the identification code scanning information.

[0104] Specifically, based on the generation factor corresponding to the identification code, user status information matching the generation factor can be obtained. The corresponding user status information is then verified for legitimacy based on pre-set legitimacy standards, completing the legitimacy verification of the identification code scan information. The legitimacy standards are pushed from the server to the payment terminal and are not unique. These standards can include at least one of the following: whether the user is on a whitelist, whether the identification code is within the set validity period, and whether the balance exceeds the minimum balance requirement.

[0105] Step S503: If the legitimacy check passes, payment is initiated based on the identification code scanning information.

[0106] Specifically, if the legitimacy check fails, it means that the user corresponding to the identification code is in a payment-unavailable state. In this case, the payment terminal will send a payment failure prompt message to the payment terminal. If the legitimacy check passes, it means that the user corresponding to the identification code is in a payment-available state. In this case, the payment terminal will initiate payment based on the identification code scan information.

[0107] In one embodiment, step S503 includes: if the offline payment condition is met, initiating offline payment based on the identification code scanning information. The offline payment condition refers to the payment terminal being in an offline state, that is, the network signal strength of the payment terminal is less than a preset signal threshold. Specifically, there is not only one way for the payment terminal to initiate offline payment based on the identification code scanning information. For example, in a scenario where the user performs a pre-recharge, the payment terminal can directly collect offline payment from the user account, or the payment terminal can periodically update the synchronization key with the server to realize offline payment of the payment terminal. In the above case, mobile payment based on dual offline identification codes can be realized.

[0108] It should be noted that after the payment terminal initiates offline payment, it needs to push the payment result and user status information to the server's message push system so that the server can generate a push message and feedback it to the corresponding payment terminal.

[0109] In the above-mentioned identification code processing method, on the one hand, the payment terminal generates the identification code based on the locally cached generation factors, that is, the payment terminal can also generate the identification code in an offline state, thereby realizing mobile payment, which is conducive to expanding the application scenarios of the mobile payment method; on the other hand, since the generation factors are obtained by updating the historical generation factors based on the latest push message, the production factors used by the payment terminal to generate the identification code correspond to the latest user status information, which can avoid the user status information contained in the identification code from being incorrect, and is conducive to improving the reliability and security of mobile payment.

[0110] For ease of understanding, the following Figure 6 The generation and processing of the identification code of this application is described in detail. Figure 6 As shown, the method implemented in this application mainly involves four systems: an industry application mobile payment program, a mobile payment code scanning terminal, a payment acquiring system, and a message push system. Among them, the industry application mobile payment program is installed on the payment terminal, the mobile payment code scanning terminal is the payment receiving terminal, and the payment acquiring system and message push system are software systems in the server.

[0111] The identification code generation and processing process specifically includes the following steps:

[0112] a) The customer fills in user information in the industry application mobile payment program to activate the offline code generation function;

[0113] b) The industry application mobile payment program determines whether the network is currently disconnected; if not, execute step c); if so, execute step d);

[0114] c) The mobile payment program directly connects to the Internet and generates and displays an identification code based on the latest generation factors; then proceeds to step h);

[0115] d) Check whether there is a valid latest push message cached locally; if not, go to step e); if so, go to step f);

[0116] e) Generate an identification code using locally cached generation factors (offline code seed, balance, user status, etc.); go to step g);

[0117] f) updating the locally cached generation factors according to the latest push message, and generating an identification code according to the updated generation factors; and proceeding to step g);

[0118] g) Scanning the QR code with a mobile payment terminal to obtain identification code scanning information;

[0119] h) The mobile payment scanning terminal verifies the legitimacy of the identification code scan information;

[0120] i) If not passed, it will show payment failed;

[0121] j) If approved, a payment request (including payment identification code, amount, transaction time, transaction goods, acquiring merchant, etc.) is initiated when the mobile payment scanning terminal and the acquiring system are connected;

[0122] k) After receiving the payment request, the acquiring system performs operations such as deducting payment and sends the payment result and user status information (including account balance, user status, identification code seed, etc.) to the message push system;

[0123] l) After the message push system obtains the payment result and user status information, it generates a corresponding push message based on the payment result and user status information, and pushes the push message to the industry application mobile payment program in a targeted and accurate manner.

[0124] The above-mentioned identification code generation and processing method, on the one hand, generates the identification code by the payment terminal based on the locally cached generation factors, that is, the payment terminal can also generate the identification code in an offline state, thereby realizing mobile payment, which is conducive to expanding the application scenarios of the mobile payment method; on the other hand, since the generation factors are obtained by updating the historical generation factors based on the latest push message, that is, the production factors used by the payment terminal to generate the identification code correspond to the latest user status information, it can avoid the occurrence of incorrect user status information contained in the identification code, which is conducive to improving the reliability and security of mobile payment and avoiding the risk of being fleeced.
