[0033] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] 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 drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0035] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0036] It should be noted that the relevant information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for display and analysis, etc.) involved in this disclosure are all information and data authorized by the user or fully authorized by all parties. For example, an interface is set up between this system and the relevant user or organization. Before obtaining relevant information, it is necessary to send an acquisition request to the aforementioned user or organization through the interface, and obtain the relevant information after receiving the consent information provided by the aforementioned user or organization.

[0037] The present invention will be described below in conjunction with preferred implementation steps. Figure 1 is a flowchart of a batch file processing method provided in accordance with an embodiment of the present application. Figure 1 As shown, the method includes the following steps:

[0038] Step S101 : determining multiple types of financial services to be batch processed, and acquiring data of each type of financial services to obtain multiple pieces of service data.

[0039] For example, the multiple pieces of business data mentioned above may include data of multiple business types.

[0040] Step S102: assemble and process multiple business data according to the target rule to obtain assembled business data, wherein the target rule indicates that the assembled business data at least includes: a file header, a total length of data, a total length of data content, extended data bits, and valid data content; the file header indicates the type information of the business data; the total length of data indicates the sum of the length of the extended data bits and the length of the valid data content; the total length of data content indicates the length of the valid data content; the extended data bits indicate the type information of the business; and the valid data content indicates the content information of the business data.

[0041] For example, the data components of a batch file may include a data header, total data length, total data content length, extended data bits, and valid data content. The data file header may occupy N bytes. The byte header identifies the current service type and is used to define a separate data header for each service. The header is unique across services. The total data length may occupy 4 bytes, representing the valid length of all data bytes excluding the header, and is used to verify the integrity of the total data bytes after parsing. The total data content length may occupy 4 bytes, representing the total number of valid batch data rows, and is used to verify the integrity of the valid batch rows after parsing. The extended data bits may occupy a minimum of 4 bytes, which can be filled as custom bits, with byte definitions based on service needs, such as timestamps, encryption vectors, unique identifiers, and serial numbers. The valid data content may represent the actual content that the batch file needs to process and read.

[0042] Step S103 , encrypting the assembled business data to obtain a batch file, wherein the batch file is used to process various types of financial business.

[0043] For example, after the business data is assembled, the assembled data is encrypted to obtain an encrypted batch file.

[0044] Through the above steps S101 to S103, the data of various types of financial businesses are assembled and processed according to specific rules (i.e., target rules) to obtain assembled business data, and then the assembled business data is encrypted to obtain a batch file. Compared with the method in which most existing batch files need to generate corresponding business batch files for each business, this solution can assemble specific identifiers according to extended data bits in a single batch file to indicate that a single file has several business types that need to be processed, thereby improving the security and versatility of the batch file, reducing the manpower and time costs brought about by generating batch files for each business, and thus improving the effect of generating batch files.

[0045] Optionally, in the batch file processing method provided in the embodiment of the present application, if the multiple types of financial services include a first type of financial service and a second type of financial service, then the multiple business data are assembled and processed according to the target rules to obtain the assembled business data, including: classifying the multiple business data to obtain first type of business data and second type of business data, wherein the first type of business data is the data of the first type of financial service, and the second type of business data is the data of the second type of financial service; assembling the first type of business data according to the target rules to obtain assembled first type of business data; assembling the second type of business data according to the target rules to obtain assembled second type of business data; obtaining assembled business data based on the assembled first type of business data and the assembled second type of business data.

[0046] For example, the first type of business data and the second type of business data can be assembled respectively according to the composition structure of the file, including the data header, total data length, total length of data content, extended data bits and valid data content (corresponding to the above-mentioned target rules), and the final assembled business data can be obtained based on the assembled first type of business data and second type of business data.

[0047] Through the above solution, data can be assembled and processed quickly and accurately according to the composition structure of the file.

[0048] Optionally, in the batch file processing method provided in the embodiment of the present application, the first type of business data is assembled and processed according to the target rules, and the assembled first type of business data includes: obtaining the file header of the first type of business data, the total data length of the first type of business data, the total length of the data content of the first type of business data, the extended data bits of the first type of business data, and the valid data content of the first type of business data according to the target rules; and obtaining the assembled first type of business data based on the file header of the first type of business data, the total data length of the first type of business data, the total length of the data content of the first type of business data, the extended data bits of the first type of business data, and the valid data content of the first type of business data.

[0049] For example, according to the special rules (corresponding to the above-mentioned target rules) set in the composition structure of the file, including the data header, total data length, total length of data content, extended data bits and valid data content, the data header, total data length, total length of data content, extended data bits and valid data content of the first type of business data are obtained, and then the assembled first type of business data is determined based on the data header, total data length, total length of data content, extended data bits and valid data content of the first type of business data.

[0050] Through the above solution, the first type of business data can be assembled and processed quickly and accurately.

[0051] Optionally, in the batch file processing method provided in the embodiment of the present application, obtaining the file header of the first type of business data, the total data length of the first type of business data, the total length of the data content of the first type of business data, the extended data bits of the first type of business data and the valid data content of the first type of business data according to the target rule includes: determining the file header of the first type of business data according to the type information of the financial business corresponding to the first type of business data according to the target rule; assembling the first type of business data to obtain the valid data content of the first type of business data, and obtaining the length information of the valid data content of the first type of business data to obtain the total length of the data content of the first type of business data; determining the extended data bits of the first type of business data based on the first type of financial business and the second type of financial business; determining the total data length of the first type of business data according to the length information of the extended data bits of the first type of business data and the length information of the valid data content of the first type of business data.

[0052] For example, the data file header can occupy N bytes. The byte data header is the identification type of the current business. It is used to define the data header separately for each business, and the data header is not repeated in the business. The total data length can occupy 4 bytes, which is the effective length of the total data bytes excluding the data header, and is used to verify the integrity of the total data bytes after parsing. The total length of the data content can occupy 4 bytes, which is the total number of rows of valid batch data, and is used to verify the integrity of the number of valid batch rows after parsing. The extended data bit can occupy the minimum 4 bytes. This bit can be filled as a custom bit and the bytes can be defined according to business needs, such as timestamp, encryption vector, unique identifier, serial number, etc. The effective data content can represent the actual content that the batch file needs to process and read, and then obtain the data header, total data length, total data content length, extended data bit and effective data content of the first type of business data.

[0053] Through the above solution, the data header, total data length, total data content length, extended data bits and valid data content of the first type of business data can be determined quickly and accurately.

[0054] Optionally, in the batch file processing method provided in the embodiment of the present application, after encrypting the assembled business data to obtain the batch file, the method further includes: decrypting the batch file to obtain a decrypted batch file; parsing the decrypted batch file according to the target rule to obtain the file header of the first type of business data, the total data length of the first type of business data, the total length of the data content of the first type of business data, the extended data bits of the first type of business data, and the valid data content of the first type of business data; based on the file header of the first type of business data, the total data length of the first type of business data, the total length of the data content of the first type of business data, the extended data bits of the first type of business data, and the valid data content of the first type of business data, multiple types of financial business are processed.

[0055] For example, the batch file can be decrypted first, and then the decrypted batch file can be parsed to obtain the data file header, total data length, total data content length, extended data bits and valid data content of the first type of business data, and the financial business can be processed based on the data file header, total data length, total data content length, extended data bits and valid data content of the first type of business data obtained by parsing.

[0056] Through the above solution, financial business can be processed quickly and accurately based on the parsed file data.

[0057] Optionally, in the batch file processing method provided in the embodiment of the present application, processing multiple types of financial services based on the file header of the first type of business data, the total data length of the first type of business data, the total length of the data content of the first type of business data, the extended data bits of the first type of business data and the valid data content of the first type of business data includes: processing the first type of financial service based on the file header of the first type of business data, the total data length of the first type of business data, the total length of the data content of the first type of business data and the valid data content of the first type of business data; determining the file header of the second type of business data, the total data length of the second type of business data, the total length of the data content of the second type of business data, the extended data bits of the second type of business data and the valid data content of the second type of business data according to the extended data bits of the first type of business data; processing the second type of financial service based on the file header of the second type of business data, the total data length of the second type of business data, the total length of the data content of the second type of business data, the extended data bits of the second type of business data and the valid data content of the second type of business data.

[0058] For example, when processing financial services, the data file header, total data length, total data content length, extended data bits and valid data content of the second type of business data can be determined based on the extended data bits of the first type of business data, and the second type of financial services can be processed based on the data file header, total data length, total data content length, extended data bits and valid data content of the second type of business data.

[0059] Through the above solution, the data structure information of the second type of service data can be easily obtained according to the extended data bits of the first type of service data.

[0060] Optionally, in the batch file processing method provided in the embodiment of the present application, processing the first type of financial business based on the file header of the first type of business data, the total data length of the first type of business data, the total data content length of the first type of business data and the valid data content of the first type of business data includes: determining whether the total data content length of the first type of business data is equal to a preset length; if the total data content length of the first type of business data is not equal to the preset length, it indicates that the parsing of the first type of business data is incorrect, and processing of the first type of financial business is prohibited; if the total data content length of the first type of business data is equal to the preset length, processing of the first type of financial business is allowed based on the file header of the first type of business data, the total data length of the first type of business data and the valid data content of the first type of business data.

[0061] For example, whether the first type of business data is parsed correctly can be determined based on the total length of the data content of the first type of business data. If it is determined that the parsing of the first type of business data is incorrect, the first type of business data can be re-parsed, and the corresponding financial business cannot be processed at this time; if it is determined that the parsing of the first type of business data is correct, the corresponding financial business can be processed.

[0062] Through the above solution, it is possible to quickly and accurately determine whether the data is parsed correctly based on the total length of the data content of the business data.

[0063] In this embodiment, in the enterprise-level file batch processing business, the security and reliability issues such as anti-leakage and anti-tampering, especially for the required batch files, batch files related to financial business or batch files related to sensitive data, business data, etc., as well as the processing flow of the overall batch file versatility are solved. It only needs to modify various business scenarios according to specific encryption rules to adapt to any business scenario, solving the problem that enterprise-level batch files need to perform additional parsing for various different businesses between different businesses.

[0064] This embodiment mainly solves the problem of generating and parsing specific rules in batch file components and file parsing, solving the defects of the actual content of batch files that do not meet the security, versatility, and tamper-proof requirements, and reducing the manpower and time costs of generating batch files for each business. For example, Figure 2 is a flowchart of a batch file parsing method based on special rules in this embodiment, and the batch file parsing method based on special rules is as follows: Figure 2 shown.

[0065] (1) Instructions for batch file assembly:

[0066] The data components of a batch file include the data header, total data length, total data content length, extended data bits, and valid data content.

[0067] 1) Data file header: occupies N bytes. The byte data header is the identification type of the current service. It is used to define the data header separately for each service. The data header is not repeated in the service.

[0068] 2) Total data length: occupies 4 bytes, excluding the effective length of the total data bytes excluding the data header, used to verify the integrity of the total data bytes after parsing.

[0069] 3) Total length of data content: occupies 4 bytes, the total number of rows of valid batch data, used to verify the integrity of the number of valid batch rows after parsing.

[0070] 4) Extended data bit: occupies the minimum 4 bytes. This bit can be filled as a custom bit and the bytes can be defined according to business needs, such as timestamp, encryption vector, unique identifier, serial number, etc.

[0071] 5) Valid data content: The batch file needs to process the actual content read.

[0072] It should be noted that each batch file can contain generation rules for multiple different businesses, and the business is divided and the corresponding parsing rules are determined based on the data header data.

[0073] The byte length of the extended data bits and the valid data content bits is not limited. When grouping files, a special method is used to calculate the number of bytes to ensure that the valid data content bytes are consistent with the total length of the data content and that the total data bytes are consistent with the total data length.

[0074] (2) File composition rules:

[0075] Define the byte length and service header data according to the service type, and finally convert them into hexadecimal. If the bytes are insufficient, fill them with 00.

[0076] 1) Total data length:

[0077] After assembling the total length of the data content, extended data bits, and valid data content excluding the file header, calculate the total bytes and convert the decimal into hexadecimal.

[0078] 2) Total length of data content:

[0079] After the effective data content is assembled, the total number of bytes of the effective content data is calculated, and finally the decimal is converted into hexadecimal.

[0080] 3) Extended data bit:

[0081] This bit is a free extension bit and can be defined according to specific services. If no definition is required, a minimum of 4 bits 00 will be filled in. It can also be used as an identifier for single-file multiple services.

[0082] 4) Effective content data:

[0083] This bit is the valid business data content. The content data is processed according to custom rules. The number of bytes occupied by each valid data bit is strictly defined and conforms to the data type format. The minimum is 4 bytes, and any digits less than the specified number are padded with 00.

[0084] After the overall data is assembled, the hexadecimal bytes are converted into binary data and saved, and finally encryption methods can be used for file encryption and transmission.

[0085] and, Figure 3 This is a schematic diagram of the file data generation rules in this embodiment. Figure 1 , Figure 4 This is a schematic diagram of the file data generation rules in this embodiment. Figure 2 ,like Figure 3 and Figure 4 As shown, the batch file data component includes the data header, total data length, total data content length, extended data bits, and valid data content.

[0086] (3) Batch file parsing rules:

[0087] It involves file decryption, hexadecimal conversion, file header parsing, data total length parsing, data content total length parsing, valid extension bit data parsing, and data content parsing.

[0088] 1) File decryption:

[0089] After obtaining the batch encrypted file, the file is first specially decrypted to obtain the original batch file.

[0090] 2) Convert hexadecimal:

[0091] Since the original batch file performs binary data conversion, you first need to convert the binary data into hexadecimal.

[0092] 3) Parsing the file header:

[0093] The hexadecimal data is parsed according to the rules of the group file. The number of bytes occupied can be defined according to different services. The file header hexadecimal data is converted into the actual file header content. The file header business type is determined and routed to the parsing method of the current business.

[0094] 4) Total length of parsed data:

[0095] According to the assembly rules, the 4-byte total length data is obtained and decimal conversion is performed. This data content will verify the integrity of the overall byte data after the total length of the data content, the extended data bits, and the valid content data are parsed.

[0096] 5) Total length of parsed data content:

[0097] According to the assembly rules, the total length of the parsed data content with a length of 4 bytes is obtained, the hexadecimal is converted to decimal, and the byte data integrity of the valid content data is verified.

[0098] 6) Parsing valid extension bit data:

[0099] Parse the corresponding data according to the assembly definition rules. If there is no special extended data assembly, parse a fixed 4 bytes.

[0100] 7) Analyze data content:

[0101] Parse the actual valid content of the file and parse the corresponding content according to the assembly rules of different businesses.

[0102] For example, Figure 5 This is a schematic diagram of parsing file data in this embodiment. Figure 5 As shown, the file can be parsed.

[0103] It should be noted that after all data contents are parsed, the number of bytes is compared with the total length of the data and the total length of the content data to ensure the integrity of the data bytes.

[0104] For example, Figure 6 This is a flowchart of file parsing in this embodiment. The file parsing process is as follows Figure 6 shown.

[0105] Compared with the prior art, the beneficial effects of this embodiment are as follows:

[0106] (1) This embodiment perfectly solves the problem of batch file content security.

[0107] (2) Compared with the method in which most existing batch files need to generate a corresponding business batch file for each business, this embodiment can assemble a specific identifier based on the extended data bits in a single batch file to indicate that a single file has several business types that need to be processed.

[0108] (3) After the overall data analysis is completed, the byte count of the total data and the valid content data needs to be compared to solve the data verification problem.

[0109] For example, Figure 7 This is a schematic diagram of the file processing interaction in this embodiment, and this embodiment uses the scenario of fund-related batch file delivery and fee deduction as an example. It includes the following process steps:

[0110] 1. The party submitting the deduction will generate a batch file based on the transaction data.

[0111] 2. Upload the assembled batch files to the storage middleware for storage, and notify the service provider to pick up and parse them.

[0112] 3. The service provider downloads the batch file from the designated storage middleware and decrypts the batch file.

[0113] 4. Convert the decrypted batch file contents from binary to hexadecimal.

[0114] 5. Parse the file header according to custom rules to obtain the business type.

[0115] Read 4 bytes according to the fixed parsing length to obtain the total length of the data.

[0116] Fixed parsing length reads 4 bytes to obtain the total length of the data content.

[0117] Parse the extended data bits, and read and process the custom data according to the rules.

[0118] Routed to the corresponding business processing logic to parse the valid data content.

[0119] 6. Check the total length of data bytes and the total length of content.

[0120] For example, suppose the message sender currently needs to send the following data:

[0121] Two types of business data need to be batch processed. The first type of business requires 100 data items to be processed, and the second type of business requires 10 data items to be processed. Table 1 shows the data for the delivery and deduction business, and Table 2 shows the business data for the operating data business.

[0122] Table 1

[0123]

[0124] Table 2

[0125]

[0126] 1. Start the assembly and delivery fee deduction business first

[0127] (1) First classify the service data and define the byte size of the data header. In this embodiment, the data header is defined as 2 bytes, and the service type is 12345, which is converted to hexadecimal as 30 39.

[0128] (2) Assemble the valid content data and define the data byte size. The deduction service is divided into five attributes. The bank card number is defined as 8 bytes, the mobile phone number is defined as 8 bytes, the deduction amount is defined as 8 bytes, and the bank channel is defined as 4 bytes. The corresponding data is converted into corresponding hexadecimal data for splicing.

[0129] All data are connected head to head in this format to obtain the complete effective content data bytes.

[0130] (3) Assemble the valid content data length. For example, if the valid data length is 100 bits, convert it to hexadecimal 00 0000 64.

[0131] (4) Assemble the extended data bits. The current batch file needs to process two different businesses in a single file, so it is necessary to define the judgment compliance. Just convert the number of remaining business types to be processed into hexadecimal. For example, if there is business data business this time, 1 is converted to hexadecimal bit 00 00 00 01.

[0132] (5) Assemble the total data length. The total data length is calculated based on the total number of valid content bytes + the total number of extended data bytes. For example, 104 bits is converted to hexadecimal 00 00 00 68.

[0133] (6) Finally, all the data are spliced ​​together to obtain the delivery data for the delivery and deduction service.

[0134] Since there is a second business that needs to be assembled in this embodiment, just follow the same business process as the first business, splice the data header of the second business to the end of the total data of the first business, and finally convert all hexadecimal data into binary to generate a complete batch file.

[0135] 2. The assembled batch file is encrypted and uploaded to the storage middleware for download by the service provider.

[0136] 3. The service provider downloads the batch file and decrypts it to obtain the original file.

[0137] 4. Convert the decrypted batch file contents from binary to hexadecimal.

[0138] 5. Parse the file from the beginning according to the custom rules to obtain the corresponding data content.

[0139] Read 2 bytes, convert them to decimal, to obtain the service type in the file header. Read 4 bytes to obtain the total data length. Read 4 bytes for the payload data length. Read 4 bytes for the extended data bit (if non-zero, it indicates that there are other service types to read). Finally, read the valid data. According to the disk data grouping rules, the byte reading is performed to define the bank card number (8 bytes), the mobile phone number (8 bytes), the deduction amount (8 bytes), and the bank channel (4 bytes). Since this embodiment has two service types, the first service's payload data length is used to determine whether the first service has been fully read. After reading the first service, the data header of the second service is read and routed to the corresponding service logic.

[0140] 6. After all data is processed, determine whether the business type data is complete based on the total data length, and then end.

[0141] In addition, it should be noted that if a batch file has only a single business type to be processed, the extended data bit can default to 00 00 00 00; if a batch file has multiple business types to be processed, the extended data bit can be defined in a custom way, but it is necessary to clearly state how many business types need to be processed, or it can be directly expressed with numbers.

[0142] For example, in various types of files, business one data can be expressed as: (business one data header + business one data total length + business one data content total length + business one data extension data bits (00 00 00 01 indicates that other businesses are included) + business one valid data content); business two data can be expressed as: (business two data header + business two data total length + business two data content total length + business two data extension data bits (00 00 00 00 indicates no other businesses) + business two valid data content); and after the business one data is spliced ​​together, the business two data is spliced ​​with the byte of business two data after the last byte of business one. If the third, fourth, and other businesses are similar, the third one is spliced ​​after the last byte code of the second one. Moreover, as long as the extended data bits are 00 00 00 01, it means that other service types are spliced ​​after the last byte code of this service. For example, if the third service is included, the extended data bits of the second service are also 00 00 00 01. If there is no fourth service, the extended data bits of the third service are 00 00 00 00.

[0143] In summary, the batch file processing method provided in the embodiment of the present application determines multiple types of financial services to be batch-processed and obtains data for each type of financial service to obtain multiple business data; assembles the multiple business data according to the target rule to obtain assembled business data, wherein the target rule indicates that the assembled business data at least includes: a file header, a total length of data, a total length of data content, an extended data bit, and valid data content, the file header indicates the type information of the business data, the total length of data indicates the sum of the length of the extended data bit and the length of the valid data content, the total length of data content indicates the length of the valid data content, the extended data bit indicates the type information of the business, and the valid data content indicates the content information of the business data; encrypts the assembled business data to obtain a batch file, wherein the batch file is used to process multiple types of financial services, which solves the problem in the related art that the generation method of batch files is poor, resulting in poor effect of generating batch files. By assembling and processing data of various types of financial businesses according to specific rules (i.e., target rules), assembled business data is obtained, and then the assembled business data is encrypted to obtain a batch file. Compared with the method in which most existing batch files need to generate corresponding business batch files for each business, this solution can assemble specific identifiers according to extended data bits in a single batch file to indicate that a single file has several business types that need to be processed, thereby improving the security and versatility of the batch file, reducing the manpower and time costs brought about by generating batch files for each business, and thus improving the effect of generating batch files.
