[0002] In business systems, the storage of user files usually relies on external file service systems.

[0003] Currently, when a user needs to upload a file, he or she can send an upload request to the business system. After receiving the request, the business system generates a token based on the request and the preset protocol and sends it to the user. The user sends the file to be uploaded and the received token to the file service module. When the file service module determines that the file to be uploaded meets the token restrictions, it stores the file to be uploaded and generates a corresponding file link to send to the user. The user sends the file link to the business system. After determining that the file link is reliable, the business system stores the file link in the corresponding business table.

[0004] However, the current file upload method cannot prevent users from maliciously uploading a large number of files, resulting in a large number of files maliciously uploaded by users occupying the file storage space and increasing the cost of file storage. Summary of the Invention

[0042] The following description sets forth many specific details to facilitate a thorough understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the scope of the present application. Therefore, the present application is not limited to the specific implementations disclosed below.

[0043] It should be noted that the terms "first", "second", "third", etc. in the claims, description and drawings of the present application are used to distinguish similar objects and are not used to describe a specific order or sequence. The data used in this way are interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than that illustrated or described herein. In addition, the terms "including", "having" and 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.

[0044] It should be understood that in the embodiments of the present application, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship. "Including A, B and / or C" means including any one, any two, or any three of A, B, and C.

[0045] It should be understood that in the embodiments of the present application, "B corresponding to A," "B corresponding to A," "A corresponds to B," or "B corresponds to A" means that B is associated with A and B can be determined based on A. Determining B based on A does not mean determining B based solely on A; B can also be determined based on A and / or other information.

[0046] In business systems, the storage of user files usually relies on external file service systems.

[0047] Currently, when a user needs to upload a file, he or she can send an upload request to the business system. After receiving the request, the business system generates a token based on the request and the preset protocol and sends it to the user. The user sends the file to be uploaded and the received token to the file service module. When the file service module determines that the file to be uploaded meets the token restrictions, it stores the file to be uploaded and generates a corresponding file link to send to the user. The user sends the file link to the business system. After determining that the file link is reliable, the business system stores the file link in the corresponding business table.

[0048] However, the current file upload method cannot prevent users from maliciously uploading a large number of files, resulting in a large number of files maliciously uploaded by users occupying the file storage space and increasing the cost of file storage.

[0049] Based on background technical reasons, in order to prevent users from maliciously uploading large amounts of files and to control file storage and traffic costs, the first embodiment of the present application provides a data processing method, which is applied to electronic devices. The electronic devices can be desktop computers, laptops, mobile phones, tablet computers, electronic watches, etc., or other electronic devices capable of data processing, which are not specifically limited in the embodiments of the present application.

[0050] The technical solution of the present application is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0051] Figure 1 This is a system diagram for implementing a data processing method provided in an embodiment of the present application. Figure 1 As shown, the system may include: user equipment, a file service system, and a business system. The user equipment is connected to the file service system and the business system respectively, and the file service system is connected to the business system.

[0052] The user device is used to send a file upload request to the business system, receive a token sent by the business system, send the file and token to the file service system, receive file information sent by the file service system, which includes a file link, and send the file information to the business system.

[0053] The file service system is used to receive files and tokens sent by user devices, and determine whether the file meets the restriction conditions through the token, and the token includes the restriction conditions for the file; if the file meets the restriction conditions, generate file information corresponding to the file; send the file information to the user device and the business system respectively; receive the restricted access instruction for the file sent by the business system, wherein the restricted access instruction is sent to the file service system by the business system after a first preset time after receiving the first file information and finding that the first file information does not exist in the business table, wherein the business table includes the file information sent by the user device, and the target user device is one of the user devices; in response to the restricted access instruction, control the first file to be inaccessible.

[0054] The business system is used to receive a file upload request sent by a target user device; generate a token in response to the file upload request, and send the token to the target user device, wherein the token includes restriction conditions for the file to be uploaded, and the token is used to determine whether the file uploaded by the target user device to the file service system meets the restriction conditions; receive first file information sent by the file service system, wherein the first file information is file information generated for the first file after the file service system receives the first file uploaded by the user device and determines through the token that the first file meets the restriction conditions; after receiving the first preset time length of the first file information, query whether the first file information exists in the business table, wherein the business table includes file information sent by the user device, and the target user device is one of the user devices; if the first file information does not exist in the business table, send a restricted access instruction for the first file to the file service system, so that the file service system controls the first file to be inaccessible in response to the restricted access instruction.

[0055] Figure 2 Schematic diagram of the data processing method provided in the embodiment of the present application. Figure 2 As shown, the method may include S201-S207.

[0056] S201: The target user device sends a file upload request to the business system.

[0057] S202: The business system receives a file upload request sent by a target user device, generates a token, and sends the token to the target user device.

[0058] For example, upon receiving a file upload request from a target user device, the service system can generate a token according to a preset protocol and then send the generated token to the target user device. The token includes restrictions on the file to be uploaded and is used to determine whether the first file uploaded by the target user device to the file service system meets the restrictions.

[0059] S203: The target user device sends the first file and the token corresponding to the first file to the file service system.

[0060] S204: After receiving the first file sent by the target user device and the token corresponding to the first file, the file service system determines whether the first file sent by the target user device meets the restriction condition based on the token corresponding to the first file.

[0061] Exemplarily, after the target user device receives the token sent by the business system, it can upload the first file with the token, that is, send the first file and the token corresponding to the first file to the file service system. After the file service system receives the first file sent by the target user device and the token corresponding to the first file, it can check whether the first file sent by the target user device meets the restrictions carried by the token. Restrictions include file size and file type, etc. For example, the first file is a picture with a size of 2.5 kilobytes (KB). The restriction in the token is that the file is a picture file and the file is less than 3KB, then the first file meets the restriction. If the restriction in the token is that the file is a picture file and the file is less than 2KB, then the first file does not meet the restriction.

[0062] S205: If the file service system determines that the first file sent by the target user device meets the restriction condition, it generates first file information corresponding to the first file and sends the first file information to the target user device and the service system.

[0063] Exemplarily, when the file service system determines that the first file sent by the target user device meets the restriction conditions, it can generate first file information corresponding to the first file. The first file information may include file information such as the file link of the first file, the upload time of the first file, the size of the first file, and the type of the first file, and send the first file information to the target user device and the business system.

[0064] S206: After receiving the first file information for the first preset time period, the business system queries the business table to see whether the first file information exists.

[0065] Exemplarily, the service table includes file information sent by user devices. That is, all file information sent by user devices to the service system can be stored in the service table, with the target user device being one of the user devices. After receiving the first file information sent by the file service system, the service system can store the first file information in the service system's storage space. The service table can include file information such as the file upload time, file size, file type, file link, file status, and the time the file status was recorded. The first file information can also include file information such as the file upload time, file size, file type, file link, file status, and the time the file status was recorded. Based on the first file information, the service table can be queried to determine whether the service table contains the first file information. Specifically, the service table includes a first preset field, and the first file information includes the first preset field. For multiple different first preset fields with the same field name, a query can be performed to determine whether the field values of the first preset fields are the same. The first preset fields can include a file upload time field, a file size field, a file type field, and a file link. First, the service table is queried to determine whether the file link for the first file exists. If the file link for the first file does not exist in the service table, it is determined that the first file information does not exist in the service table, and no further query is performed on the other first preset fields except the file link. If there is a file link to the first file in the business table, compare whether the upload time of the first file in the business table is the same as the upload time of the first file in the first file information, compare whether the file size of the first file in the business table is the same as the file size of the first file in the first file information, and compare whether the file type of the first file in the business table is the same as the file type of the first file in the first file information. If all are the same, it is determined that the first file information exists in the business table. If the field value of any of the above fields is different, it is determined that the first file information does not exist in the business table.

[0066] For example, the first preset duration is m minutes, the file information of file Y includes a file link of file Y, the upload time of file Y is time t, the type of file Y is a picture, and the size of file Y is 4KB. m minutes after receiving the file information of file Y, the business system queries whether the file information of file Y exists in the business table. First, it can query whether there is a file link of file Y in the business table. If there is no file link of file Y in the business table, it is directly determined that the file information of file Y does not exist in the business table. If there is a file link of file Y in the business table, it is necessary to further query whether the upload time of file Y in the business table is time t, whether the type of file Y in the business table is a picture, and whether the size of file Y in the business table is 4KB. If any of the upload time, type, and size of file Y in the business table are different from those in the file information of file Y, it is determined that the file information of file Y does not exist in the business table.

[0067] S207: If the business system finds that the first file information does not exist in the business table, it sends an access restriction instruction for the first file to the file service system, so that the file service system controls the first file to be inaccessible in response to the access restriction instruction.

[0068] For example, the business system can monitor each uploaded file from a business perspective using first file information. After receiving the first file information from the file service system, the target user device sends the first file information to the business system. The business system checks whether the domain name of the first file information belongs to a trusted file service system. If the domain name of the first file information belongs to a trusted file service system, the first file information can be saved in a business table, completing the upload of the first file. Optionally, after receiving the first file information from the file service system, the target user device sends the first file information to the business system. After receiving the first file information from the target user device, the business system can compare the first file information received from the target user device with the first file information received from the file service system. If the first file information received from the target user device and the first file information received from the file service system are inconsistent, it is determined that the target user device may have maliciously uploaded the file, and an access restriction instruction for the first file can be sent to the file service system, so that the file service system, in response to the access restriction instruction, controls access to the first file. If the first file information received from the target user device and the first file information received from the file service system are consistent, the first file information can be saved in the business table, completing the upload of the first file. When the business system finds that the first file information does not exist in the business table described below within the first preset time period, the business system determines that the target user device has received the first file information but has not sent the first file information to the business system. The first preset time period can be understood as a reasonable time period reserved by the business system for the target user device to send the first file information to the business system. If the target user device has received the first file information but has not sent the first file information to the business system after the first preset time period, the target user device is considered to have a risk of maliciously uploading a large number of files. The business system will send an access restriction instruction for the first file to the file service system, so that the file service system controls the first file inaccessible in response to the access restriction instruction.

[0069] For example, user A and the business system both receive file information of file X sent by the file service system at time T0. The business system searches the business table at time T1 and finds that file information X does not exist. Time T1 is the time n minutes after time T0. The business system sends a file X access restriction instruction to the file service system at time T1. The file service system can control access to file X based on the file X access restriction instruction. For example, it can restrict access to the server by specific IP addresses, ports, or protocols, thereby achieving control over file access. File access control can be achieved by modifying the file configuration file (such as httpd.conf or .htaccess file).

[0070] Optionally, the above S207, if the business system queries that the first file information does not exist in the business table, sends a restricted access instruction for the first file to the file service system, so that the file service system controls the first file to be inaccessible in response to the restricted access instruction, may also include: if the first file information does not exist in the business table, recording the status of the first file in the first file information as failed review, and sending a restricted access instruction for the first file to the file service system, so that the file service system controls the first file to be inaccessible in response to the restricted access instruction.

[0071] Exemplarily, the business table also includes a second preset field, and the first file information includes the second preset field. The second preset field may include the status of the file and the time of recording the file status. The status of the first file may include a pending status, an audit passed status, a deleted status, and an audit failed status. When the business system receives the first file information, the initial status of the first file in the first file information is a pending status. When it is found that the first file information does not exist in the business table, the status of the file in the first file information can be updated to an audit failed status. Specifically, if the first file information does not exist in the business table, the field value of the second preset field in the first file information is recorded as an identifier indicating that the first file has failed the audit, that is, the field value of the file status field is recorded as a field value indicating that the first file has failed the audit, and the field value of the file status time field is recorded as a field value indicating that the first file has failed the audit.

[0072] For example, different preset characters can be used to represent different states of the first file, character 1 represents the pending state, character 2 represents the approved state, character 3 represents the deleted state, and character 4 represents the unapproved state. When the business system receives the first file information, the initial state of the first file in the first file information is the pending state, that is, the field value of the file status field in the first file information is character 1. When it is found that the first file information does not exist in the business table, the file status field in the first file information can be changed from character 1 to character 4.

[0073] Optionally, if the business system finds that the first file information exists in the business table, the status of the first file in the business table is recorded as an approved status.

[0074] Based on the above embodiment, for example, when it is found that the business table contains the first file information, the file status field in the first file information may be changed from character 1 to character 2.

[0075] The embodiment of the present application increases the interaction between the business system and the file service system. The file service system generates file information and sends the file information to the user device while also sending the file information to the business system. The file upload process can be fully supervised from the business level, thereby preventing users from maliciously uploading large amounts of files and controlling file storage and traffic costs.

[0076] In an optional embodiment, the above method may also include: after receiving the second preset time length of the first file information, if the first file information still does not exist in the business table, sending a deletion instruction for the first file to the file service module, so that the file service system deletes the first file in response to the deletion instruction, wherein the second preset time length is greater than the first preset time length.

[0077] For example, after receiving the first file information for the second preset time period, the business system may query the business table to see whether the first file information exists. If the first file information still does not exist in the business table at this time, it is considered that the target user device will no longer send the first file information to the business system, and the risk of the target user device maliciously uploading a large number of files increases, so the first file may be determined to be an invalid file. The business system may update the file status in the first file information to a deleted state, and send a delete instruction for the first file to the file service module, so that the file service system deletes the first file in response to the delete instruction. After receiving the first file information for the second preset time period, if the first file information exists in the business table, a release access restriction instruction for the first file is sent to the file service module, so that the file service system controls the first file to resume normal access in response to the release access restriction instruction.

[0078] Based on the above embodiment, for example, after the business system sends a command to restrict access to file X to the file service system at time T1, it can again query the business table at time T2 to see whether the first file information exists. Time T2 is the time after time T1 plus m hours. If the first file information still does not exist in the business table at time T2, the business system can send a delete command to the file service system, so that the file service system deletes file X in response to the delete command. If the first file information exists in the business table at time T2, the business system can send a command to release access restrictions to the file service system, so that the file service system controls normal access to the first file in response to the command.

[0079] Figure 3 Another flow chart of the data processing method provided in the embodiment of the present application. Figure 3 As shown, the business system can traverse the first file information whose file status is "review failed" and determine whether the time since the first file information was received exceeds a second preset time. If the time since the first file information was received exceeds the second preset time and the first file information still does not exist when the business table is queried, the file status of the first file information can be updated to a deleted state and a delete instruction can be sent to the file service system so that the file service system deletes the first file in response to the delete instruction. If the time since the first file information was received exceeds the second preset time and the first file information exists when the business table is queried, the file status of the first file in the business table can be updated to a reviewed state.

[0080] This embodiment sends a deletion instruction for the first file to the file service module if the first file information still does not exist in the business table after the second preset time period has passed since the first file information was received, so that the file service system deletes the first file in response to the deletion instruction. This can delete invalid files, reduce the storage space occupied by invalid files, and lower file storage costs. Furthermore, if it is determined that the first file information still does not exist in the business table after the second preset time period, the first file is deleted, rather than immediately deleting the first file if the first file information does not exist in the business table after the first preset time period. This avoids the business system accidentally deleting the first file if the user delays sending the first file information to the business system due to forgetfulness or delay, thereby reducing the risk of accidental deletion and improving the reliability of the business system's file upload management.

[0081] In an optional embodiment, the above method may further include: querying whether the first file information exists in the service table every third preset time period after the first file information is received.

[0082] For example, after receiving the first file information, every third preset time period, the business table may be queried to determine whether the first file information exists, thereby achieving real-time monitoring of file uploads and further improving the stability of the business system in managing file uploads.

[0083] In an optional embodiment, the restriction condition includes a business type, the first file information includes a business type corresponding to the first file, and after receiving the first preset time length of the first file information, querying whether the first file information exists in the business table, including: determining the sub-business table corresponding to the business type of the first file from multiple sub-business tables according to the business type; after receiving the first preset time length of the first file information, querying whether the first file information exists in the sub-business table.

[0084] Exemplarily, business types may include player show pictures, user avatars, character retrieval certification documents, and product pictures, etc. The business table includes sub-business tables corresponding to different business types. Each business type may correspond to a sub-business table, and the sub-business tables may include player show picture tables, user avatar tables, character retrieval certification document tables, and product picture tables, etc. After receiving the first preset time of the first file information, the business system can determine the sub-business table corresponding to the first file from multiple sub-business tables based on the business type, and then query whether the first file information exists in the sub-business table corresponding to the first file. The restriction condition including the business type can also ensure that the files uploaded in each business scenario are in line with expectations, effectively preventing users from maliciously transmitting errors. For example, different scenarios have different restrictions on uploading files. For example, the business scenario of character retrieval proof documents allows uploading videos, while the business scenario of user avatars allows uploading only pictures. In the existing technology, a malicious user obtains an upload token with looser restrictions from the character retrieval proof documents, uploads a video file, and then submits the link of the video file to the user avatar interface. The system will also determine that the upload is successful. The restriction conditions include business type to avoid the above situation as much as possible.

[0085] For example, taking the business types including player show pictures and user avatars as an example, Figure 4 This is another flow chart of the data processing method provided in the embodiment of the present application. Figure 4 As shown, the business type of the first file information can be determined. When the business type of the first file information is a player show picture, it is determined whether the first file information exists in the sub-business table corresponding to the player show picture. If it exists, the status of the first file in the sub-business table corresponding to the player show picture is determined to be an approved state. If it does not exist, the status of the first file in the first file information is determined to be an unapproved state, and a restricted access instruction is sent to the file service system so that the file service system controls the first file to be inaccessible in response to the restricted access instruction. Similarly, when the business type of the first file information is a user avatar, refer to the above-mentioned processing method when the business type of the first file information is a player show picture, and no further details will be given here.

[0086] In an optional embodiment, the above method may also include: every time the fourth preset time period passes, determining the first number of first file information received within the fourth preset time period before the current moment; obtaining the second number of first file information received within multiple fourth preset time periods before the current moment, and determining the average number of first file information received within multiple fourth preset time periods; if the first number is greater than the average number or the difference between the first number and the average number is greater than a preset threshold, sending a warning signal.

[0087] For example, it can be determined that the number of first file information received every 10 minutes within an hour is number 1, number 2, number 3, number 4, number 5, and number 6 respectively. The average of number 1, number 2, number 3, number 4, number 5, and number 6 is then calculated to be number 7. The numbers 1, number 2, number 3, number 4, number 5, and number 6 are compared with number 7. When any of the values of number 1, number 2, number 3, number 4, number 5, and number 6 is greater than number 7, it indicates that the number of files sent by the user device during that time period is abnormal, and there is a risk of maliciously uploading a large number of files. An early warning signal is sent to prompt relevant operators to make further judgments. The difference between number 1, number 2, number 3, number 4, number 5, and number 6 and number 7 can also be calculated. When the difference is greater than a preset threshold, it indicates that the number of files sent by the user device during that time period is abnormal, and there is a risk of maliciously uploading a large number of files. An early warning signal is sent to prompt relevant operators to make further judgments.

[0088] In an optional embodiment, the above method may also include: if the business system queries the business table and finds that there is first file information, sending the first file information to the AI audit model, the AI audit model is used to obtain the first file based on the first file information, and perform content audit on the first file to obtain the audit result of the first file; when the audit result of the first file indicates that the first file audit fails, sending a restricted access instruction for the first file to the file service system, so that the file service system controls the first file to be inaccessible in response to the restricted access instruction.

[0089] For example, when a user device sends first file information to a business system, the business system saves the first file information in a business table. The first file information saved in the business table is considered to have been legally uploaded by the user device. However, to prevent the user device from uploading prohibited content such as prohibited images, the content of the first file can be reviewed by an AI review model. The AI review model sends the review result to the business system. If the business system determines that the received review result is a failure, it sends an access restriction instruction to the file service module, so that the file service system controls access to the first file in response to the access restriction instruction.

[0090] Optionally, files that fail the AI audit model can also be manually reviewed to ensure their legitimacy and security. This design not only ensures that files sent by user devices meet business requirements, but also effectively prevents the spread of inappropriate content, improving system stability and reliability.
