The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The terms "first", "second", etc. may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0047] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 , an embodiment of the upload verification method of the attachment in the embodiment of the present invention includes:

[0048] 101. Added new tasks for receiving attachments;

[0049] In this embodiment, the attachment adding task given by the user is accepted. The attachment adding task can be added for different business scenarios. The business scenarios can be different scenarios such as budget preparation, asset management, risk assessment, internal control and auditing, product procurement, etc. Different attachment adding tasks can be specified and set based on different business scenarios.

[0050] 102. Determine whether the newly added task in the attachment has a designated business configuration;

[0051] In this embodiment, it is determined whether there is a specified business configuration setting in the attachment adding task, so as to select attachment uploading requirements and data sorting requirements that are suitable for the business according to different specified business settings.

[0052] 103. When there is a specified business configuration, the specified business configuration option is displayed to the preset client, and the attachment data uploaded by the customer is monitored;

[0053] In this embodiment, when there is a specified business configuration, such as the specified business is a reimbursement application, it will be displayed as a general expense reimbursement form. The corresponding business options include reimbursement time, reimbursement items, and reimbursement amount. The attachment upload requirements are reimbursement electronic invoices, reimbursement form vouchers and other data.

[0054] 104. When there is no designated business configuration, determining whether there is a general configuration for the newly added task in the attachment;

[0055] In this embodiment, if the attachment newly added task does not have a specified business configuration, it is analyzed whether the attachment newly added task has a general configuration, and the general configuration can display all business configuration data so that the user can upload and adjust the global data. The general configuration can also be some daily matters such as procurement, outing application, meeting application and other tasks that are not specific to a specific business.

[0056] Furthermore, after step 104, the following specific implementations are also included:

[0057] 1041. When the attachment adding task considers that there is no common configuration, the attachment adding task is marked as an abnormal task, and the attachment adding task is written into the processing log.

[0058] In step 1041, if there is neither general configuration nor specified business configuration in the attachment adding task, the attachment adding task is considered to be abnormal data, the attachment adding task is marked as an abnormal task, and the attachment adding task is written into the processing log so that the user can subsequently check and handle the abnormal situation.

[0059] 105. When there is a general configuration, the general configuration options are displayed to the preset client, and the attachment data uploaded by the customer is monitored;

[0060] In this embodiment, when there is a general configuration option in the attachment adding task, the relevant filled-in check data of the general configuration option is displayed on the client, waiting for the user to upload the relevant attachment according to the demand.

[0061] See also Figure 2 , Figure 2 This is a schematic diagram of a specific embodiment of step 103 and step 105 of the attachment upload verification method in an embodiment of the present invention. The "monitoring the attachment data uploaded by the customer" in step 103 and step 105 includes the following specific implementation methods:

[0062] 1051. Receive attachment data uploaded by the user;

[0063] 1052. Perform restriction verification processing on the attachment data according to the preset upload restriction rule to obtain a verification result;

[0064] 1053. When the verification result is qualified, the attachment data is written into the preset cache memory.

[0065] In steps 1051-1053, a standardized interface is provided for the business node to automatically identify the current business scenario when executing, and automatically identify the attachment related information that needs to be uploaded configured by the business scenario according to the current business scenario, and notify the user interface module to display the corresponding upload requirements, and provide management functions such as retrieval, download, and deletion of the attachments uploaded by the user. The user configures the corresponding attachment upload rules according to the characteristics of the business node, and judges whether the attachment data meets the requirements of the attachment upload rules through the relevant restrictions of the attachment upload rules. After meeting the requirements of the upload rules, the attachment data is written into the cache memory, so that the user can modify and adjust the uploaded attachments, and timely change the uploaded attachment content data, providing more flexibility in attachment upload.

[0066] Specifically, the upload restriction rules include: attachment file format, attachment upload quantity, attachment file size, and attachment upload token. The upload restriction rules include restrictions on attachment type, file format, file size, quantity, whether attachments must be uploaded, etc., where attachment types include but are not limited to documents, pictures, videos, electronic invoices, etc.

[0067] 106. Receive an adjustment instruction from a user, and perform content adjustment processing on the attachment data according to the adjustment instruction to obtain adjusted attachment data;

[0068] In this embodiment, after receiving the user adjustment instruction, the uploaded attachment can be adjusted, and the attachment data can be flexibly adjusted online to generate the adjusted attachment data. If the attachment data identifies a date range, the identified date range can be modified to obtain a new date range. For the reimbursement type identified in the attachment data, the user adjusts the reimbursement type through the adjustment instruction to obtain the adjusted attachment data.

[0069] 107. According to the preset form ID and the preset to-do node information, the adjusted attachment data is verified to obtain attachment verification data;

[0070] In this embodiment, the to-do node information is a processing node of the current business type, for example, the business type of applying for going out, in which case the attachment data is a filling node of the outgoing address, and the attachment form should be an address form. Verify whether the form name in the attachment data and the address in the outgoing address are correct to obtain the attachment verification data.

[0071] See also Figure 3 , Figure 3 This is an embodiment of step 107 of the method for verifying the upload of an attachment in an embodiment of the present invention, and step 107 includes the following specific implementation methods:

[0072] 1071. When the preset to-do node information is a reimbursement application, the data format of the adjustment attachment data is analyzed;

[0073] 1072. When the data format is a picture or a PDF document, the adjustment attachment data is identified and processed according to a preset ORC identification algorithm to obtain an attachment form name;

[0074] 1073. When the data format is a Word document or a TXT document, copy the characters in the adjusted attachment data to obtain the attachment form name;

[0075] 1074. Determine whether the attachment form name matches the preset form id;

[0076] 1075. When the preset form ID is matched, the attachment verification data is marked as a qualified format;

[0077] 1076. When the preset form ID is not matched, the attachment verification data is marked as an unqualified format.

[0078] In steps 1071-1076, the corresponding business system is configured as the reimbursement application module in the attachment configuration, the business node is configured as the reimbursement application as the to-do node, the corresponding form is the ordinary expense reimbursement form, and the uploaded document type is the ordinary attachment and the electronic invoice. When the data format is a picture or a PDF document, the ORC recognition algorithm is used to identify and extract the data of the picture or PDF document, and the first row of the recognized data is sorted in order as the attachment form name.

[0079] When the data format is a Word document or TXT document, read 1-25 characters in the Word document or TXT document, find non-blank characters from the initial blank characters, intercept until multiple consecutive blank characters or line breaks are identified, and copy multiple characters as the attachment form name. Match the attachment form name with the preset form id. The matching settings can be semantic matching, fuzzy matching, precise character matching, etc. When matching the form id, mark the attachment verification data as qualified format. When not matching the form id, mark the attachment verification data as unqualified format.

[0080] Specifically, step 1073 includes the following specific implementation methods:

[0081] 10731. Based on a preset character sorting range, characters in the adjusted attachment data are copied in sequence to obtain an attachment form name.

[0082] In step 10731, the character sorting range is set to 1-25 characters, the characters in the adjusted attachment data are copied in sequence, and the copied character string is intercepted according to the interception rule to obtain the attachment form name.

[0083] Furthermore, after step 107, the following specific implementations are also included:

[0084] 1071. When the attachment verification data is in an unqualified format, a format abnormality message is sent to the client;

[0085] 1072. Monitor user interaction to issue a new adjustment instruction, and perform adjustment processing on the adjustment attachment data according to the new adjustment instruction to generate new adjustment attachment data.

[0086] In steps 1071-1072, when it is detected that the attachment verification data is in an unqualified format, a format exception message is sent to the client so that the user can readjust the attachment format after knowing that the attachment format is incorrect. Based on the new adjustment instruction given by the user, the adjustment attachment data is modified and adjusted again to obtain new adjustment attachment data. The new adjustment attachment data is returned to step 107 as the adjustment attachment data for loop processing. That is, after the review and modification, the attachment configuration query is performed again according to the document type, process review node information, etc. to display the attachment information and allow the user to process the configured attachment information at the review node.

[0087] 108. When the attachment verification data is in a qualified format, the adjusted attachment data is uploaded to a preset storage database.

[0088] In this embodiment, after the attachment data is confirmed to be in a qualified format, the number of adjusted attachments can be uploaded into a pre-set storage database, which can be a cloud database or a locally deployed database. This application scheme improves the automation and intelligence level of attachment information management in the internal control system, ensures the security and integrity of attachment information in different business scenarios, reduces the risk of information leakage, and realizes attachment upload through configuration rather than coding, avoiding waste of resources and improving resource utilization efficiency.

[0089] Specifically, after step 108, the following specific implementation methods are also included:

[0090] 1081. Receive an attachment download instruction, wherein the attachment download instruction includes: a target feature code and a delivery address;

[0091] 1082. Query the storage database for target attachment data corresponding to the target feature code;

[0092] 1083. Transmit the target attachment data to the delivery address.

[0093] In steps 1081-1083, the user may need to download the attachment from the storage database, so after receiving the user's attachment download instruction, the relevant data is downloaded from the storage database. The attachment download instruction contains a target feature code, which is the storage location token returned by the storage database during the storage process. Based on the storage location token, the corresponding storage file can be accurately found from the storage database. The attachment download instruction also includes a delivery address, which points to the address where the attachment needs to be transmitted. The delivery address can be an IP address. The delivery address can also be another cloud database address, and the transmission security of the storage database is guaranteed by isolated transmission.

[0094] In the embodiment of the present invention, by performing general configuration and specific business configuration analysis on the attachment adding task, the attachment adding task is flexibly classified and displayed to the customer on different filling configuration pages. The customer uploads different attachments according to different pages, and receives the user's adjustment instructions, and the content of the attachment data can be adjusted on the upload page. According to the to-do node information, the adjusted attachment data is verified, which realizes the flexible verification of the attachment upload of the internal control system and improves the efficiency of attachment verification.
