[0067] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0068] Figure 1 This is a flowchart illustrating a health code display processing method according to an embodiment of the present invention, as shown below. Figure 1As shown, the health code display processing method provided in this embodiment of the invention includes:

[0069] Step S1: Read the offline health code area data of the bank card and obtain the offline current location information and offline current time information; the offline health code area data includes the offline health code credibility, offline health code status, offline health code status timestamp, and offline travel information of the adjacent preset number of days before the current day.

[0070] Step S2: If it is determined that the credibility of the offline health code is greater than the preset credibility threshold, then the offline current location information and the offline current time information are added to the offline itinerary information to obtain updated offline itinerary information, and the offline health code status timestamp is updated according to the offline current time information.

[0071] Step S3: Write the updated offline health code status timestamp and the offline updated travel information to the bank card, and display the offline health code status.

[0072] In step S1 above, the device reads the offline health code area data of the bank card and obtains the offline current location information and offline current time information; the offline health code area data includes the offline health code credibility, offline health code status, offline health code status timestamp, and offline travel information for the adjacent preset number of days prior to the current day. The device can be a computer device that executes this method, such as a terminal, specifically a smart terminal. The acquisition, storage, use, and processing of data in this application's technical solution all comply with the relevant provisions of national laws and regulations.

[0073] like Figure 2 As shown, the relevant execution entities for implementing the methods of the embodiments of the present invention may include bank card 100, smart terminal 200, bank server 300 and health code server 400;

[0074] Specifically, the bank card 100 communicates with the smart terminal 200 via NFC, the smart terminal 200 communicates with the bank server 300 via the Internet, and the bank server 300 communicates with the health code server 400 via the Internet.

[0075] The bank card 100 can be a CPU card commonly used by commercial banks, featuring large storage space, fast read speed, and support for multiple uses. To achieve the invention's purpose, based on the partitionable nature of CPU card data, the data partitions of the bank card 100 can include a financial area and a health code area. The financial area is used to store encrypted data related to the bank card's financial account; the health code area is used to store health code-related data, including health code token ciphertext, health code status (e.g., green, yellow, red), travel information for the past n days (n is a preset number of days, n can be selected as 7), health code credibility (e.g., level A (greater than a preset credibility threshold, i.e., can be defined as level A), level B, level C), health code status timestamp, etc.

[0076] The smart terminal 200 can be a mobile phone, tablet computer, or other smart device, used to run a bank APP, interact with the bank card 100 and the bank server 300, and display the health code status of the bank card holder. It includes a motherboard, NFC module, GPS module, communication module, and display module; wherein:

[0077] The motherboard is used for computing, storage, and control of the terminal.

[0078] The NFC module is used to read and write data on bank card 100 via NFC technology, and can use communication protocols such as ISO14443.

[0079] The GPS module is used to obtain the GPS location information of the smart terminal 200.

[0080] The communication module is used to establish Internet-based communication with the bank server 300.

[0081] The display module is used to display the health code status.

[0082] The bank server 300 is used to respond to data requests from the smart terminal 200 and to request health code-related information from the health code server 400.

[0083] The health code server 400 is used to respond to health code data requests from the bank server 300 and to store public health code data. It is generally operated by a local institution. This method mainly includes three steps: activating the health code S100, reading the health code online S200, and reading the health code offline S300. S100 is used to enable the health code function of the bank card 100. Specific steps are as follows... Figure 3 As shown:

[0084] Step S101: Run the bank APP on the smart terminal 200 and log in to the personal real-name account;

[0085] Step S102: In the bank APP, the financial area data of the bank card 100 is read via NFC, and the encrypted data of the financial area data and the login user information are sent to the bank server 300.

[0086] In step S103, the bank server 300 decrypts the ciphertext and obtains the real name information of the bank card holder. It then compares the decrypted real name information with the login user information to confirm whether the cardholder and the login user are consistent. If they are consistent, the cardholder is allowed to proceed with the subsequent steps.

[0087] In step S104, the bank server 300 requests the health code information of the real-name user from the health code server 400, including health code token, health code status, travel information in the past n days, health code credibility, health code status timestamp, etc.

[0088] In step S105, the bank server 300 encrypts the health code token obtained in step S104 and returns the health code token ciphertext, health code status, travel information for the past n days, health code credibility, health code status timestamp, and other information to the smart terminal 200.

[0089] In step S106, the smart terminal 200 writes the data returned in step S105 into the health code area of ​​the bank card 100 via NFC.

[0090] S200 is used to obtain the health code information of the bank card holder when the network status of the smart terminal 200 is good. The specific steps are as follows: Figure 4 As shown:

[0091] Step S201: Use the smart terminal 200 to read the health code area data A (first health code area data) of the bank card 100, and obtain the terminal's GPS location information GPS_INFO (current location information) and current time information TIME_INFO (current time information), and transmit data A, GPS_INFO, and TIME_INFO to the bank server 300;

[0092] In step S202, the bank server 300 decrypts the encrypted health code token in data A and transmits the decrypted health code token to the health code server 400.

[0093] In step S203, the health code server 400 returns the corresponding user's health code data B (second health code area data) to the bank server 300 based on the health code token;

[0094] In step S204, the bank server 300 compares the timestamps of data A and data B (the second health code status timestamp and the first health code status timestamp). If the timestamps match, it is considered that the bank card 100 is synchronized with the health code information of the corresponding user stored in the health code server 400, and then step S205 is executed; if the timestamps do not match, it is considered that the bank card 100 is not synchronized with the health code information of the corresponding user stored in the health code server 400, and step S206 is executed.

[0095] Step S205: The bank server 300 generates the latest timestamp TIME_STAMP (current status timestamp of the health code), updates GPS_INFO and TIME_INFO to the RECENT_JOURNEY (first updated travel information) of the past n days in data A, and sends RECENT_JOURNEY and TIME_STAMP to the health code server 400;

[0096] Step S206, the bank server 300 calculates the union of the travel data (first travel information and second travel information) of the past n days in data A and data B;

[0097] In step S207, the bank server 300 queries the cardholder's offline merchant transaction data for the past n days, parses the registered address of the corresponding merchant, and then adds the merchant address and transaction time as itinerary data to the union data to obtain RECENT_JOURNEY (second updated itinerary information), and sends RECENT_JOURNEY and TIME_STAMP to the health code server 400.

[0098] In step S208, the health code server 400 updates the RECENT_JOURNEY and TIME_STAMP of the corresponding user, calculates the health code status HEALTH_STATUS of the corresponding user based on the updated RECENT_JOURNEY (health server updates travel information), and returns HEALTH_STATUS to the bank server 300.

[0099] In step S209, after receiving HEALTH_STATUS, the bank server 300 calculates the health code credibility HEALTH_CREDIT according to rule R1, and returns TIME_STAMP, RECENT_JOURNEY (first updated travel information or second updated travel information), HEALTH_STATUS and HEALTH_CREDIT to the smart terminal 200.

[0100] In step S210, after receiving the return message, the smart terminal 200 writes TIME_STAMP, RECENT_JOURNEY, HEALTH_STATUS, and HEALTH_CREDIT into the bank card 100 via the NFC protocol; the message may include the aforementioned TIME_STAMP, RECENT_JOURNEY, HEALTH_STATUS, and HEALTH_CREDIT.

[0101] Step S211, the smart terminal 200 displays HEALTH_STATUS data;

[0102] Rule R1 calculates health code credibility into three levels: A, B, and C, based on dimensions such as the cardholder's financial attribute score in the bank's database, the frequency of using the bank card to obtain the health code, and the data consistency between the bank card health code and the health code server 400. Specifically, the scores corresponding to the financial attribute score, the frequency of using the bank card to obtain the health code, and the data consistency can be obtained respectively. Then, the total score is calculated based on the weights corresponding to the financial attribute score, the frequency of using the bank card to obtain the health code, and the data consistency. If the total score is greater than the preset credibility threshold, the health code credibility can be defined as level A.

[0103] S300 is used to obtain the health code information of the bank card holder when the network status of the smart terminal 200 is abnormal. The specific steps are as follows: Figure 5 As shown:

[0104] Step S301: The smart terminal 200 reads the health code area data A (offline health code area data) of the bank card and obtains the terminal's GPS location information GPS_INFO (offline current location information) and current time information TIME_INFO (offline current time information);

[0105] In step S302, the smart terminal 200 determines whether the travel data for the most recent n days in data A is empty. If it is empty, it jumps to step S306; if it is not empty, it jumps to step S303.

[0106] In step S303, the smart terminal 200 determines whether the credibility of the health code in data A is A. If it is A, then proceed to step S304; otherwise, proceed to step S306.

[0107] Step S304: The smart terminal 200 updates GPS_INFO and TIME_INFO to the RECENT_JOURNEY (updated offline travel information) of the past n days in data A, generates the latest timestamp TIME_STAMP, and writes TIME_STAMP (updated offline health code status timestamp) and RECENT_JOURNEY into the bank card 100 via the NFC protocol;

[0108] Step S305, the smart terminal 200 displays HEALTH_STATUS data (offline health code status);

[0109] In step S306, the smart terminal 200 displays the message "Offline query mode is temporarily unavailable (cannot show health code status offline). Please query again when the network is good."

[0110] Step S1 corresponds to step S301 above, and the preset number of days can be set independently according to the actual situation.

[0111] In step S2 above, if the device determines that the credibility of the offline health code is greater than a preset credibility threshold, it adds the offline current location information and the offline current time information to the offline travel information to obtain updated offline travel information, and updates the offline health code status timestamp according to the offline current time information. This step S2 corresponds to steps S303 and S304 above, and the preset credibility threshold can be set independently according to the actual situation.

[0112] In step S3 above, the device writes the updated offline health code status timestamp and the offline updated travel information to the bank card, and displays the offline health code status. This step S3 corresponds to S304 and S305 above.

[0113] The health code display processing method also includes:

[0114] If the credibility of the health code is determined to be less than or equal to a preset credibility threshold, a prompt message indicating that the offline health code display status cannot be used is generated. This corresponds to S303 and S306 above.

[0115] The travel information is periodically cleared; correspondingly, the health code display processing method also includes:

[0116] If the travel information is determined to be empty, a prompt message indicating that the offline health code cannot be displayed is generated. This corresponds to S302 and S306 above.

[0117] 1. This invention is based on the characteristics of bank cards rather than smartphones, and has greater universality than existing solutions. It can effectively cover groups such as the elderly, teenagers, and children who do not have smartphones, and has high social value.

[0118] 2. This invention supports offline acquisition of health code information for groups with good credit and high usage frequency, which can effectively solve the loading problem of the current health code scheme when the network conditions are poor, and can effectively improve the efficiency of social operation;

[0119] 3. The real-time online health code acquisition solution of this invention can effectively solve the problems of screenshot fraud, screen recording fraud, and image modification fraud existing in the current health code solution, thus safeguarding the epidemic prevention work and having high social value;

[0120] 4. This invention forcibly records travel information every time a health code is obtained, which can effectively solve the problem of incomplete travel records in the current health code scheme, and is conducive to improving the screening efficiency of high-risk groups, thus having high social value;

[0121] 5. This invention can supplement the traditional health code data with financial data, making the travel data richer.

[0122] The health code display processing method provided in this embodiment of the invention reads the offline health code area data of a bank card and obtains the offline current location information and offline current time information. The offline health code area data includes offline health code credibility, offline health code status, offline health code status timestamp, and offline travel information for the adjacent preset number of days prior to the current day. If it is determined that the offline health code credibility is greater than a preset credibility threshold, the offline current location information and the offline current time information are added to the offline travel information to obtain updated offline travel information, and the offline health code status timestamp is updated according to the offline current time information. The updated offline health code status timestamp and the updated offline travel information are written to the bank card, and the offline health code status is displayed, enabling the display of the health code offline, thereby facilitating people's travel.

[0123] Furthermore, the health code display processing method also includes:

[0124] If the credibility of the health code is determined to be less than or equal to a preset credibility threshold, a prompt message indicating that the health code cannot be displayed offline will be generated. This is similar to the explanation above and will not be repeated here.

[0125] The health code display processing method provided in this embodiment of the invention can not use offline health code display when the health code credibility is determined to be less than or equal to a preset credibility threshold, thereby further ensuring the reliability of health code display.

[0126] Furthermore, the travel information is periodically cleared; correspondingly, the health code display processing method also includes:

[0127] If the travel information is determined to be empty, a message indicating that the offline health code cannot be displayed will be generated. Please refer to the above explanation; further details are omitted.
