[0055] 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, and the collection, use and processing of relevant data must comply with relevant regulations. The acquisition, storage, use, and processing of data in the technical solution of this application are in compliance with relevant provisions of national laws and regulations.

[0056] The cross-system data query method provided in the embodiment of the present application can be applied to the application environment shown in Figure 1. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. Among them, the terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car devices, projection devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The head-mounted device can be a virtual reality (VR) device, an augmented reality (AR) device, smart glasses, etc. The server 104 can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services.

[0057] In an exemplary embodiment, Figure 2 As shown, a cross-system data query method is provided, and the method is applied to the automatic teller machine terminal in Figure 1 as an example for explanation. Among them:

[0058] S202: Receive a data query request for a target service, where the data query request includes a query identifier.

[0059] The user interface on the ATM can be operated to receive user input, and the back-end server processes the data query request and communicates with the database of the provident fund center. The data query request includes a query identifier, which can be a bank card. The user inserts the bank card into the ATM and enters the password on the user interface for identity authentication. After verifying that the bank card information and password are correct, the ATM displays the provident fund query option. The user selects the provident fund query and sends the data query request to the business service system.

[0060] S204: Send the data query request to the business service system, so that the business service system determines the sub-service system identifier and user information to which the target business belongs based on the query identifier in the data query request, and sends the user information to the sub-service system corresponding to the sub-service system identifier.

[0061] The business service system can be a housing reform financial banking service system. Traditional self-service ATMs can only provide customers with basic banking services such as deposits, withdrawals, and transfers. Through the housing reform financial banking service system, provident fund information can be queried on the self-service ATM. The business service system determines the sub-service system identifier and user information to which the target business belongs based on the query identifier in the data query request. The target business can be querying the user's provident fund, and the sub-service system can be the branch system to which the bank card belongs obtained according to the query identifier. The user information can be the type of certificate, certificate number, and name, etc.

[0062] S206: Receive target information of the target business system returned by the sub-service system, where the target information is determined by the sub-service system based on the received user information.

[0063] After receiving the user information, the sub-service system determines the target information corresponding to the user information, and determines the target business system according to the target information. The target business system may be a provident fund system.

[0064] S208: Sending the data query request to the target business system according to the target information.

[0065] S210: Receive data query results obtained by the target business system based on the target information, and display the data query results.

[0066] The sub-service system receives the customer information and determines which provident fund system the customer information belongs to, and then sends the query request to the corresponding provident fund system. The data query results obtained based on the target information are returned all the way to the ATM interface for display.

[0067] The user inserts a bank card into the ATM, starts the business page to enter the housing reform financial banking service system, and chooses to query the provident fund information. The housing reform financial banking service system queries the account opening institution number and the customer's three-factor information based on the bank card number. The customer's three-factor information may include the certificate type, certificate number and name. The first-level branch number is calculated based on the account opening institution number. The housing reform financial banking service system can send the first-level branch number and the customer's three-factor information to the branch system based on the routing system of the branch system interaction in various places. The branch system calls the specific provident fund center based on the customer's three-factor information. The provident fund center obtains the data query result based on the query request, and the query result is returned to the ATM interface for display.

[0068] Figure 3 A schematic diagram of cross-system data query in one embodiment.

[0069] In the above-mentioned cross-system data query method, the user operates on the ATM, performs data query operations, and sends the data query request to the business service system. The business service system is connected to the sub-service system, and the sub-service system is connected to the target business system. The target business system then transmits the data query results to the ATM and displays the data query results, thereby ensuring the accuracy and timeliness of the data.

[0070] In an exemplary embodiment, the data query request is transmitted using a data packet in an extensible markup language format.

[0071] The user enters the query identifier through the front-end interface, and a data query request in the extensible markup language (XML) format containing the query identifier is generated based on the user input. The data query request in XML format is sent to the business service system. After receiving the query request in XML format, the business service system parses the query identifier to determine the sub-service system identifier and user information to which the target business belongs, encapsulates the user information into an XML format data packet, and sends it to the corresponding sub-service system to obtain the target information. Based on the encapsulated XML format target information, it is sent to the target business system to obtain the data query result, and then the XML format data query result is returned to the ATM for display. When it comes to data exchange between different systems, the use of XML can ensure cross-system compatibility and interoperability.

[0072] In an exemplary embodiment, the method further comprises:

[0073] Establishing a security context with a target business system, wherein the security context includes at least one key;

[0074] A security context check value is generated based on the key, and the check value is sent together with the security context to a target business system, so that the target business system can verify the received security context check value based on the key.

[0075] In secure communications, keys are used to encrypt and decrypt data, ensuring that only the party holding the corresponding key can read the message content. An encryption algorithm is used to calculate the entire security context based on the key to generate a check value to verify whether the security context has been modified or replaced during transmission. The security context and its check value are sent to the target business system. After the target business system receives the security context and check value, it uses the same key and algorithm to calculate the check value again. If the newly calculated check value matches the received check value, it proves that the security context has not been tampered with.

[0076] In an exemplary embodiment, the method further comprises:

[0077] Receiving an encrypted data query result, wherein the encrypted data query result is generated based on a message authentication code, the data query result, and a key;

[0078] Decrypting the encrypted data query result based on the key to obtain a decrypted message authentication code;

[0079] Whether the data query result is correct is verified based on the decrypted message authentication code.

[0080] The receiver receives the encrypted data query result. This encryption process is completed by the sender using a specific key to ensure that only the receiver with the correct key can read the target information. After encrypting the target information, the sender also needs to generate a message authentication code (MAC), which is usually calculated using a key and a cryptographic hash function. The function of the message authentication code is to ensure that the data has not been tampered with during transmission. The receiver also needs to use the same key and hash function to recalculate the decrypted message authentication code and compare it with the received message authentication code. If the two message authentication codes match, it proves that the information has not been modified during transmission; if they do not match, it indicates that there may be security issues, such as information tampering or key leakage.

[0081] In an exemplary embodiment, the method further comprises:

[0082] When the security context check value and the message authentication code are both verified to be correct, the data query result is displayed.

[0083] If the security context check value and the message authentication code (MAC) are both verified correctly, it means that the integrity and authenticity of the data are guaranteed, that is, the data has not been tampered with and is indeed from the expected sender.

[0084] In an exemplary embodiment, presenting the data query result includes:

[0085] Determining keywords in the data query results according to a keyword thesaurus;

[0086] The keywords in the data query results are displayed after being blocked.

[0087] Use a predefined keyword word library to identify sensitive or blocked keywords in the data query results. The keyword word library can be a list that contains words that need to be blocked. The identified keywords are replaced or hidden to protect privacy or sensitive information. The blocking method can be to replace characters with asterisks, completely replace with other characters, or directly delete them. The data query results after keyword blocking are displayed to the user.

[0088] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0089] Based on the same inventive concept, the embodiment of the present application also provides a cross-system data query device for implementing the cross-system data query method involved above.
