Description

Technical Field

[0001] The present application relates to the general field of data processing technology, and in particular to a method and device for preprocessing tax bureau data. Background Art

[0002] At present, the interaction resources of the national tax bureau are in short supply. Due to the limited interface and data resources of the tax bureau, the interaction between banks and the tax bureau will take a long time due to network delays or other reasons. In addition, there are many restrictions on the interaction between banks and the tax bureau, such as the format of the data sent, the configuration of the port, etc. If there are problems in the interaction process, the interaction time will be further extended, which will delay the business processing process between the bank and other customers. Summary of the Invention

[0003] The embodiment of the present application provides a tax bureau data preprocessing method and device. By establishing a tax bureau simulation system, the process of interaction between the bank and the tax bureau is truly simulated. When the bank interacts with the tax bureau, it can interact with the tax bureau simulation system to determine whether there are any problems in the interaction process with the tax bureau, so as to make corrections in advance and reduce the time of interaction with the tax bureau.

[0004] In a first aspect, an embodiment of the present application provides a tax bureau data preprocessing method, which is applied to a tax bureau server simulation system. The tax bureau server simulation system includes a tax data storage, an encryption and decryption processor, and a bank external server. The bank external server is connected to a bank server. The tax data storage includes a message directory consisting of at least one message entry. Each message entry in the at least one message entry stores corresponding tax data. The method includes:

[0005] The bank server simultaneously sends a first tax data request message to the tax bureau server and the bank external server;

[0006] The bank external server receives the first tax data request message from the bank server and sends the first tax data request message to the encryption and decryption processor;

[0007] The encryption / decryption processor decrypts the first tax data request message to obtain a second tax data request message, and sends the second tax data request message to the bank external server;

[0008] The bank external server calls the message directory to find a first message entry corresponding to the second tax data request message, and calls the tax data corresponding to the first message entry to send to the encryption and decryption processor;

[0009] The encryption / decryption processor encrypts the tax data corresponding to the first message item to obtain second tax data, and sends the second tax data to the bank external server;

[0010] The bank external server sends the second tax data to the bank server;

[0011] The bank server performs a risk control test on the corresponding target user according to the second tax data to obtain a risk control test result;

[0012] The bank server receives the third tax data from the tax bureau server, and compares the second tax data with the third tax data to determine whether the second tax data and the third tax data are identical;

[0013] If the second tax data is the same as the third tax data, the risk control test result is used as the risk control test result of the target user.

[0014] It can be seen that in the embodiment of the present application, the bank server sends a first tax data request message to the tax bureau server and the bank external server at the same time. The bank external server decrypts the first tax data request message through the encryption and decryption processor to obtain a second tax data request message. The message entry corresponding to the second tax data request message is queried through the tax data storage device, and the tax data under the message entry is sent to the bank server after encryption. The bank server performs a risk control test on the target user based on the tax data to obtain a risk control test result. After receiving the tax data from the tax bureau, the bank server compares the tax data of the two to determine whether the data is the same. If the data is the same, the risk control test result is used as the risk control test result for the target user. Since each interaction between the bank server and the tax bureau server takes a long time, the above method is used. The bank server conducts risk control tests on target users based on the tax data obtained from the tax bureau server simulation system, and makes corresponding arrangements based on the risk control test results. After obtaining the tax data from the tax bureau server, if the tax data of the tax bureau server is the same as the tax data of the tax bureau server simulation system, the subsequent business will be carried out directly according to the risk control test results. This shortens the construction period of the loan business and improves the processing efficiency of the loan business.

[0015] In a feasible embodiment, before the bank server simultaneously sends the first tax data request message to the tax bureau server and the bank external server, the method also includes: the bank server sends an authentication request to the bank external server; the bank external server identifies whether the sending port corresponding to the authentication request is the SMS verification port corresponding to the bank server, and if the sending port corresponding to the authentication request is the SMS verification port corresponding to the bank server, then sends an SMS verification code to the bank server; after receiving the SMS verification code, the bank server sends an authentication request to the tax bureau server using the same type of port.

[0016] In this embodiment of the present application, the bank server sends an authentication request to the bank's external server. The external server then identifies the corresponding sending port based on the authentication request. If so, the external server sends an SMS verification code to the bank server. After receiving the SMS verification code, the bank server sends an authentication request to the tax bureau server using the same port. Since each interaction between the bank and the tax bureau typically takes a long time, the aforementioned method can avoid the extended authentication and authorization process caused by port errors.

[0017] In a feasible embodiment, before the encryption / decryption processor decrypts the first tax data request message to obtain the second tax data request message, the method further includes: the encryption / decryption processor obtains an encryption / decryption JAR package provided by a tax bureau server document; the encryption / decryption processor converts the encryption / decryption JAR package into an encryption call class file and a decryption call class file;

[0018] The encryption and decryption processor decrypts the first tax data request message to obtain the second tax data request message, including: the encryption and decryption processor decrypts the first tax data request message by decrypting the calling class file. If the decryption of the first tax data request message is successful, the second tax data request message is obtained; if the decryption of the first tax data request message is unsuccessful, a decryption error file is obtained, and the decryption error file is sent to the bank server calling the server; the bank server calling the server sends the decryption error file to the bank server; the bank server modifies the first tax data request message according to the decryption error file and resends it to the bank external server and the tax bureau server.

[0019] In an embodiment of the present application, the encryption and decryption processor obtains the encryption and decryption JAR package provided by the tax bureau server document and converts it into corresponding encryption call class files and decryption call class files. The first tax data request message is then decrypted using the decryption call class files. If the decryption is unsuccessful, a decryption error file is generated and sent to the bank server via the bank's external server. The bank server modifies the first tax data request message using the decryption error file and resends it to the tax bureau server and the bank's external server. Since each interaction between the bank and the tax bureau typically takes a long time, the aforementioned method can prevent the bank from extending the tax data acquisition process due to errors in the encryption format of the message.

[0020] In a feasible embodiment, the bank external server sends the second tax data to the bank server, including: the bank external server sends the second tax data to the bank server synchronously; or the bank external server sends the second tax data to the bank server asynchronously; the bank server predicts the time when the tax bureau server sends the third tax data based on the type of the second tax data sent.

[0021] In the embodiment of the present application, the tax data transmission method between the bank's external server and the bank server can be used to predict the tax data transmission time between the bank server and the tax bureau server, thereby allowing for reasonable arrangements for other services in advance.

[0022] In a feasible embodiment, the tax bureau server simulation system also includes a performance feedback processor, and the method also includes: the bank external liaison server receives a first user loan data message sent from the bank server, and sends the first user loan data message to the encryption and decryption processor; the encryption and decryption processor decrypts the first user loan data message to obtain a second user loan data message, and sends the second user loan data message to the performance feedback processor; the performance feedback processor verifies the data format of the second user loan data message, obtains a first verification result, and sends the first verification result to the bank external liaison server; the bank external liaison server sends the first verification result to the bank server; the bank server modifies the first user loan data message according to the first verification result, and sends the modified first user loan data message to the tax bureau server.

[0023] In this embodiment of the present application, after receiving first user loan data from a bank server, the bank external server decrypts the first user loan data through an encryption and decryption processor to obtain second user loan data. The second user loan data is then sent to a performance feedback processor. The performance feedback processor verifies the data format and generates a first verification result. The first verification result is then sent to the bank server via the bank external server. The bank server corrects the data format of the first user loan data based on the first verification result before sending it to the tax bureau server. This method can avoid delays in the bank's loan data exchange with the tax bureau due to incorrect loan data formats.

[0024] In a feasible embodiment, the tax bureau server simulation system also includes a tax data update processor, and the method also includes: the tax data update processor retrieves the tax data in the tax data storage device, and performs error analysis on the tax data to determine whether there is erroneous data in the tax data; if there is erroneous data in the tax data, an error data message entry is generated according to the error type of the error data, and the error data message entry is stored in the message directory, and the corresponding error data and the tax data of the user corresponding to the error data are stored under the error data message entry; if the bank external server calls the message directory to find the first message entry corresponding to the second tax data request message, the tax data stored under the first message entry is also stored in the error data message entry, then the bank external server sends the corresponding error data under the error data message entry to the bank server.

[0025] In this embodiment of the present application, the tax data update processor analyzes tax data for errors, generates error data message entries based on any error data, and stores these entries in the tax data storage. When the bank's external server retrieves the message entries and finds the first message entry corresponding to the second tax data request message, if the tax data stored in the first message entry is also stored in the error data message entry, the error data is also sent to the bank server. This method improves the richness of tax data and facilitates risk control testing of target users by the bank server.

[0026] In a feasible embodiment, the tax data update processor performs an error analysis on the tax data, including: the tax data update processor determines whether the tax data meets the first condition, and determines the tax data that does not meet the first condition as erroneous data; the first condition includes: whether the tax data meets the authenticity and legality; and whether the data character length of the enterprise name data in the tax data is less than the first character length; and whether the enterprise name and legal person name in the tax data corresponding to different users in the tax data are the same.

[0027] In this embodiment of the present application, the data update processor performs error analysis on the tax data, primarily by determining the authenticity and legality of the tax data, the character length of the company name data in the tax data, and whether the company name and the legal person name are identical. This allows for thorough analysis of errors in the tax data.

The tax bureau server simulation system includes a tax data storage device, an encryption and decryption processor, and a bank external server. The bank external server is connected to a bank server.

[0035] a risk control unit, configured for the bank server to perform a risk control test on the corresponding target user according to the second tax data to obtain a risk control test result;

[0037] If the second tax data is the same as the third tax data, the risk control test result is used as the risk control test result of the target user.

[0049] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] The terms "first," "second," and so on, in the specification and claims of this application and the accompanying drawings are used to distinguish between different objects, not to describe a specific order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps is not limited to the listed steps but may optionally include steps not listed, or may optionally include other steps inherent to the process, method, product, or apparatus.

[0051] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0052] See also Figure 1 , Figure 1 A structure schematic diagram of a tax bureau server simulation system provided by an embodiment of the present application is shown in Figure 1 The tax bureau server simulation system 100 includes an effectiveness feedback processor 101, a tax data storage 102, an encryption and decryption processor 103, a bank external server 104, and a tax data update processor 105. The bank external server 104 is connected with a bank server 110, for realizing data interaction between the tax bureau server simulation system 100 and the bank server 110. The bank server 110 is also connected with a tax bureau server 120, for realizing data interaction between the bank server 110 and the tax bureau server 120.

[0053] The bank needs to send loan data to the tax bureau after completing a loan business with a user. The bank needs to send the loan data to the tax bureau in a specified data format. The interaction between the bank and the tax bureau needs a long time. In order to avoid the interaction time between the bank and the tax bureau being lengthened due to data format problems when the bank sends loan data to the tax bureau, the bank can send the loan data to the tax bureau server simulation system 100 through the bank server 110, and the effectiveness feedback processor 101 checks the data format of the loan data. The bank corrects the loan data according to the checking result of the effectiveness feedback processor 101 and then sends the loan data to the tax bureau, so that the interaction time between the bank and the tax bureau is not lengthened due to data format errors.

[0054] The bank and the tax bureau perform encryption on data in a specified format, and the encryption and decryption processor 103 is used to realize encryption and decryption processing on the interaction data. The tax data storage 102 stores a message directory including at least one message entry, and each message entry in the at least one message entry stores corresponding tax data. The tax bureau server simulation system 100 performs data interaction with the bank server 110 in the form of a message. Each tax data is converted into a message form according to a specified message template, and the tax data in the tax data storage 102 is obtained from the tax bureau server 120 under a specified condition. The tax data update processor 105 mainly analyzes error data in the tax data storage 102, and updates the error data to the tax data storage 102 through other message entries, so as to improve the richness of the data.

[0055] Based on this, an embodiment of the present application provides a tax bureau data preprocessing method, which is described in detail below with reference to the accompanying drawings.

[0056] Please refer to Figure 2 , Figure 2A flow chart of a tax bureau data preprocessing method provided in an embodiment of the present application, wherein the tax bureau data preprocessing method is applied to Figure 1 The tax bureau server simulation system shown in the figure includes a tax data storage, an encryption and decryption processor and a bank external server, the bank external server is connected to the bank server, the tax data storage includes a message directory consisting of at least one message entry, and each message entry in the at least one message entry stores corresponding tax data, such as Figure 2 As shown, the method includes the following steps:

[0057] In step 201, the bank server sends a first tax data request message to the tax bureau server and the bank's external server simultaneously.

[0058] Before receiving a user's loan request, a bank needs to conduct a risk control test on the user to determine whether there is any risk in issuing the loan to the user. To conduct this risk control test, the bank needs to obtain the user's tax data from the tax bureau.

[0059] In a feasible embodiment, before the bank server simultaneously sends the first tax data request message to the tax bureau server and the bank external server, the method also includes: the bank server sends an authentication request to the bank external server; the bank external server identifies whether the sending port corresponding to the authentication request is the SMS verification port corresponding to the bank server, and if the sending port corresponding to the authentication request is the SMS verification port corresponding to the bank server, then sends an SMS verification code to the bank server; after receiving the SMS verification code, the bank server sends an authentication request to the tax bureau server using the same type of port.

[0060] Among them, before the bank interacts with the tax bureau, it needs to establish a port connection with the tax bureau, and then perform authentication and authorization. Only after completing authentication and authorization can data interaction be carried out. The tax bureau server simulation system also has this function. In the process of authentication and authorization between the tax bureau server simulation system and the bank server, the bank server will send an authentication request to the tax bureau server simulation system. After receiving the authentication request, the tax bureau server simulation system will identify through the bank's external server whether the sending port corresponding to the authentication request is the SMS verification port corresponding to the bank server. If the sending port is the corresponding SMS verification port, the bank's external server will send an SMS verification code to the bank server. After receiving the SMS verification code, the bank server will send an authentication request to the tax bureau server according to the same type of port.

[0061] In this embodiment of the present application, the bank server sends an authentication request to the bank's external server. The external server then identifies the corresponding sending port based on the authentication request. If so, the external server sends an SMS verification code to the bank server. After receiving the SMS verification code, the bank server sends an authentication request to the tax bureau server using the same port. Since each interaction between the bank and the tax bureau typically takes a long time, the aforementioned method can avoid the extended authentication and authorization process caused by port errors.

[0062] In step 202, the bank external server receives a first tax data request message from the bank server and sends the first tax data request message to the encryption and decryption processor.

[0063] Among them, when the bank and the tax bureau exchange data, they will use the prescribed encryption method to encrypt the data. Therefore, when the bank's external server receives the first tax data request message from the bank server, it needs to send it to the encryption and decryption processor for decryption.

[0064] In step 203, the encryption / decryption processor decrypts the first tax data request message to obtain a second tax data request message, and sends the second tax data request message to the bank external server.

[0065] Among them, the interaction between the bank server and the tax bureau server simulation system is mainly carried out through the bank's external server. Therefore, after the encryption and decryption processor decrypts the first tax data request message, it needs to be sent to the bank's external server for identification and then subsequent operations.

[0066] In a feasible embodiment, before the encryption / decryption processor decrypts the first tax data request message to obtain the second tax data request message, the method further includes: the encryption / decryption processor obtains an encryption / decryption JAR package provided by a tax bureau server document; the encryption / decryption processor converts the encryption / decryption JAR package into an encryption call class file and a decryption call class file;

[0067] The encryption and decryption processor decrypts the first tax data request message to obtain the second tax data request message, including: the encryption and decryption processor decrypts the first tax data request message by decrypting the calling class file. If the decryption of the first tax data request message is successful, the second tax data request message is obtained; if the decryption of the first tax data request message is unsuccessful, a decryption error file is obtained, and the decryption error file is sent to the bank server calling the server; the bank server calling the server sends the decryption error file to the bank server; the bank server modifies the first tax data request message according to the decryption error file and resends it to the bank external server and the tax bureau server.

[0068] The encryption and decryption processor encrypts and decrypts the messages sent from the bank server in accordance with the encryption and decryption methods specified for interaction between the bank and the tax bureau. Therefore, the encryption and decryption processor obtains the encryption and decryption JAR package provided by the tax bureau server and converts it into corresponding encryption call class files and decryption call class files. This conversion process can be achieved through the Python+Jpype third library, which converts the encryption and decryption JAR package into Python-type encryption call class files and decryption call class files. The encryption and decryption processor decrypts the first tax data request message using the decryption call class files. If the decryption is unsuccessful, it indicates that the encryption format of the encrypted message provided by the bank server is incorrect. In this case, the encryption and decryption processor generates a decryption error file and sends it to the bank server via the bank's external server. The bank server modifies the first tax data request message based on the decryption error file and then resends it to the bank's external server and the tax bureau server.

[0069] In an embodiment of the present application, the encryption and decryption processor obtains the encryption and decryption JAR package provided by the tax bureau server document and converts it into corresponding encryption call class files and decryption call class files. The first tax data request message is then decrypted using the decryption call class files. If the decryption is unsuccessful, a decryption error file is generated and sent to the bank server via the bank's external server. The bank server modifies the first tax data request message using the decryption error file and resends it to the tax bureau server and the bank's external server. Since each interaction between the bank and the tax bureau typically takes a long time, the aforementioned method can prevent the bank from extending the tax data acquisition process due to errors in the encryption format of the message.

[0070] In step 204, the bank's external server calls the message directory to find the first message entry corresponding to the second tax data request message, and calls the tax data corresponding to the first message entry to send to the encryption and decryption processor.

[0071] The message directory stores all message entries, and the first message entry corresponding to the second tax data request message can be quickly found through the message directory.

[0072] For example, see Figure 3 , Figure 3 This is a schematic diagram of the structure of a message directory provided in an embodiment of the present application. Figure 3 As shown, Figure 3 The message directory 30 includes N message entries, and each message entry stores corresponding tax data. The bank external server searches the N message entries for the corresponding message entry according to the second tax data request message.

[0073] In step 205, the encryption / decryption processor encrypts the tax data corresponding to the first message item to obtain second tax data, and sends the second tax data to the bank's external server.

[0074] Wherein, corresponding to the above embodiment, the encryption and decryption processor encrypts the tax data corresponding to the first message item through the encryption call class file and then sends it to the bank external server.

[0075] Step 206: The bank's external server sends the second tax data to the bank server.

[0076] The bank external server sends the second tax data to the bank server in the form of a message, and the message is converted according to a prescribed message template.

[0077] In a feasible embodiment, the bank external server sends the second tax data to the bank server, including: the bank external server sends the second tax data to the bank server synchronously; or the bank external server sends the second tax data to the bank server asynchronously; the bank server predicts the time when the tax bureau server sends the third tax data based on the type of the second tax data sent.

[0078] Among them, when the tax bureau server sends tax data to the bank server, it may be sent synchronously or asynchronously. To achieve asynchronous sending, the tax bureau server simulation system can use Flask+Swagger to push data in a semi-automated manner to send the set tax data asynchronously. Different tax bureaus may have different sending methods. Some tax bureaus send synchronously, while others send asynchronously. The interaction time corresponding to synchronous and asynchronous sending will also be different. Therefore, according to the sending method of the tax bureau server simulation system, the time of the data sending stage when interacting with the tax bureau server can be determined, so as to reasonably arrange some other business.

[0079] In the embodiment of the present application, the tax data transmission method between the bank's external server and the bank server can be used to predict the tax data transmission time between the bank server and the tax bureau server, thereby allowing for reasonable arrangements for other services in advance.

[0080] In step 207 , the bank server performs a risk control test on the corresponding target user based on the second tax data to obtain a risk control test result.

[0081] Among them, after the bank server obtains the corresponding second tax data from the tax bureau server simulation system, it will immediately conduct a risk control test on the target user based on the second tax data, so as to obtain the risk control test results of the target user in advance, and make corresponding arrangements in advance based on the risk control test results, thereby reducing the construction period.

[0082] In step 208 , the bank server receives the third tax data from the tax bureau server, and compares the second tax data with the third tax data to determine whether the second tax data and the third tax data are identical.

[0083] Among them, after receiving the third tax data from the tax bureau server, the bank server will not immediately perform risk control testing based on the third tax data, because the bank server has already performed risk control testing based on the second tax data. At this time, the second tax data and the third tax data are compared to determine whether the second tax data and the third tax data are the same.

[0084] Step 209: If the second tax data is the same as the third tax data, the risk control test result is used as the risk control test result of the target user.

[0085] If the second and third tax data are identical, the risk control test results obtained by the bank server based on the second tax data for the target user are correct. The bank can then proceed directly with the subsequent work corresponding to the risk control test results.

[0086] In a feasible embodiment, the tax bureau server simulation system also includes a performance feedback processor, and the method also includes: the bank external liaison server receives a first user loan data message sent from the bank server, and sends the first user loan data message to the encryption and decryption processor; the encryption and decryption processor decrypts the first user loan data message to obtain a second user loan data message, and sends the second user loan data message to the performance feedback processor; the performance feedback processor verifies the data format of the second user loan data message, obtains a first verification result, and sends the first verification result to the bank external liaison server; the bank external liaison server sends the first verification result to the bank server; the bank server modifies the first user loan data message according to the first verification result, and sends the modified first user loan data message to the tax bureau server.

[0087] Among them, if the bank's risk control test results for the target user show that there is no risk, then the bank may issue a loan to the target user. After the bank completes the loan business for the target user, it needs to send the loan data to the tax bureau, such as the loan amount, detailed information of the target user, etc. However, when the bank sends the loan data to the tax bureau, it needs to use some prescribed data formats. If the data format is incorrect, it needs to be modified. However, since each interaction between the bank and the tax bureau takes a long time, if any modification occurs, it will take even more time.

[0088] The tax bureau server simulation system also includes a performance feedback processor, which is used to verify the data format of loan data. After the bank server sends a first user loan data message to the bank's external server, the encryption and decryption processor is still required to decrypt the first user loan data message to obtain a decrypted second user loan data message. The performance feedback processor verifies the data format of the second user loan data message to obtain a first verification result, which is sent to the bank server via the bank's external server. The bank server then modifies the data format of the first user loan data based on the first verification result before sending it to the tax bureau server.

[0089] In this embodiment of the present application, after receiving first user loan data from a bank server, the bank's external server decrypts the first user loan data via an encryption / decryption processor to obtain second user loan data. The second user loan data is then sent to a performance feedback processor, which verifies the data format and generates a first verification result. The first verification result is then sent to the bank server via the bank's external server. The bank server then corrects the data format of the first user loan data based on the first verification result before sending it to the tax bureau server. This method can avoid delays in the bank's loan data exchange with the tax bureau due to incorrect loan data formats.

[0090] In a feasible embodiment, the tax bureau server simulation system also includes a tax data update processor, and the method also includes: the tax data update processor retrieves the tax data in the tax data storage device, and performs error analysis on the tax data to determine whether there is erroneous data in the tax data; if there is erroneous data in the tax data, an error data message entry is generated according to the error type of the error data, and the error data message entry is stored in the message directory, and the corresponding error data and the tax data of the user corresponding to the error data are stored under the error data message entry; if the bank external server calls the message directory to find the first message entry corresponding to the second tax data request message, the tax data stored under the first message entry is also stored in the error data message entry, then the bank external server sends the corresponding error data under the error data message entry to the bank server.

[0091] In addition to accessing the tax data stored in the tax bureau server, the tax bureau server simulation system also performs error analysis on this data to determine if errors exist. This primarily involves updating the tax data for other abnormal scenarios. This facilitates risk control testing of target users by the bank server based on the tax data, thereby enhancing the richness of the tax data. The tax bureau server simulation system performs error analysis on tax data through a tax data update processor. This processor retrieves tax data from the tax data storage and performs error analysis. If errors are found, an error data message entry is generated based on the error data and stored in a message entry in the tax data storage. The error data message entry stores the corresponding error data and the tax data of the user corresponding to the error data. Therefore, when the bank's external liaison server searches the message directory for the first message entry corresponding to the second tax data request message, if the tax data stored in the first message entry also exists in the error data message entry, the bank's external liaison server sends the error data to the bank server simultaneously with the second tax data.

[0092] In this embodiment of the present application, the tax data update processor analyzes tax data for errors, generates error data message entries based on any error data, and stores these entries in the tax data storage. When the bank's external server retrieves the message entries and finds the first message entry corresponding to the second tax data request message, if the tax data stored in the first message entry is also stored in the error data message entry, the error data is also sent to the bank server. This method improves the richness of tax data and facilitates risk control testing of target users by the bank server.

[0093] In a feasible embodiment, the tax data update processor performs an error analysis on the tax data, including: the tax data update processor determines whether the tax data meets the first condition, and determines the tax data that does not meet the first condition as erroneous data; the first condition includes: whether the tax data meets the authenticity and legality; and whether the data character length of the enterprise name data in the tax data is less than the first character length; and whether the enterprise name and legal person name in the tax data corresponding to different users in the tax data are the same.

[0094] Among them, the tax data update processing mainly conducts error analysis of tax data based on the authenticity and legality of the tax data. For example, whether there are illegal tax numbers, illegal ID numbers or illegal mobile phone numbers in the tax data, etc. After judging the authenticity and legality, it will also judge whether the data character length of the enterprise name data is too long, and whether the enterprise name and legal person name are the same.

[0095] In this embodiment of the present application, the data update processor performs error analysis on the tax data, primarily by determining the authenticity and legality of the tax data, the character length of the company name data in the tax data, and whether the company name and the legal person name are identical. This allows for thorough analysis of errors in the tax data.

[0096] It can be seen that in the embodiment of the present application, the bank server sends a first tax data request message to the tax bureau server and the bank external server at the same time. The bank external server decrypts the first tax data request message through the encryption and decryption processor to obtain a second tax data request message. The message entry corresponding to the second tax data request message is queried through the tax data storage device, and the tax data under the message entry is sent to the bank server after encryption. The bank server performs a risk control test on the target user based on the tax data to obtain a risk control test result. After receiving the tax data from the tax bureau, the bank server compares the tax data of the two to determine whether the data is the same. If the data is the same, the risk control test result is used as the risk control test result for the target user. Since each interaction between the bank server and the tax bureau server takes a long time, the above method is used. After the bank server obtains the tax data from the tax bureau server simulation system, it conducts risk control testing on the target users and makes corresponding arrangements based on the risk control test results. After obtaining the tax data from the tax bureau server, if the tax data of the tax bureau server is the same as the tax data of the tax bureau server simulation system, the subsequent business will be carried out directly according to the risk control test results, which shortens the loan business period and improves the processing efficiency of the loan business.
