[0071] The implementation, functional features, and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments

[0072] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0073] An embodiment of the present application provides a file upload method based on the IOS side. The execution subject of the file upload method based on the IOS side includes, but is not limited to, at least one of an electronic device such as a server, a terminal, etc. that can be configured to execute the method provided in the embodiment of the present application. In other words, the file upload method based on the IOS side can be executed by software or hardware installed on a terminal device or a server device. The server includes, but is not limited to: a single server, a server cluster, a cloud server, or a cloud server cluster, etc. The server can be an independent server or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, Content Delivery Network (CDN), and big data and artificial intelligence platforms.

[0074] Refer to Figure 1 As shown, it is a schematic flowchart of a file upload method based on the IOS side according to an embodiment of the present invention. In this embodiment, the file upload method based on the IOS side includes:

[0075] S1. Extract the file configuration from the file to be uploaded, and apply for an upload format for the file to be uploaded according to the file configuration to obtain an upload domain name and an upload scenario value.

[0076] Specifically, the file configuration refers to the configuration information of the file. The file configuration includes data such as the file type and the file size. Among them, the file type refers to the type of file to be uploaded, such as pictures, documents, videos, etc., which is used to help the server determine the required storage area and resources. The file size refers to the size of the file to be uploaded, which is used to help the server side determine whether it meets the specific file size upper limit requirement.

[0077] Specifically, the file to be uploaded refers to the file that needs to be uploaded. The file to be uploaded can be a multimedia file such as an image, a video, or a document. The upload domain name refers to the target server address of the file upload request. The upload domain name is the actual recipient of the file upload. For example, the upload domain name can be https: / / upload.example.com.

[0078] Specifically, the upload scenario value is a further refinement and classification of the file upload scenario, used to distinguish different types of file upload requirements. The upload scenario value is usually a predefined string or number, identifying the specific upload purpose or business scenario. Through the upload scenario value, the server can provide personalized configurations for the upload operation according to the file purpose, file type, or storage requirements. For example, when the file to be uploaded is a user profile image, the corresponding upload scenario value is profile image; when the file to be uploaded is a file or document, the corresponding upload scenario value is document.

[0079] In the embodiment of the present invention, referring to Figure 2 as shown, extracting the file configuration from the file to be uploaded includes:

[0080] S21. Perform format recognition on the file to be uploaded to obtain the file type;

[0081] S22. Perform size statistics on the file to be uploaded to obtain the file size;

[0082] S23. Extract the file name from the file to be uploaded to obtain the file name;

[0083] S24. Perform file dependency analysis on the file to be uploaded to obtain the file dependency path;

[0084] S25. Perform upload target analysis on the file to be uploaded to obtain the file upload target;

[0085] S26. Trace the scenario of the file to be uploaded according to the file dependency path and the file upload target to obtain the upload scenario data;

[0086] S27. Generate the file configuration according to the file type, the file size, the file name, and the upload scenario data.

[0087] Specifically, the format recognition refers to extracting the suffix name of the file to be uploaded and determining the file type according to the suffix name. For example, the file type corresponding to the suffix name jpg is the image type. The size statistics can be performed by the FileManager method or directly reading the file byte count method.

[0088] Specifically, the name can be extracted by querying the last component name in the local path of the file to be uploaded. The scenario traceability refers to tracing the usage scenario corresponding to the upload operation of the file to be uploaded.

[0089] Specifically, the file dependency analysis refers to extracting the API call path of the file to be uploaded and the dependency relationships between the various files called by the API. The upload target analysis refers to extracting the target node of the upload of the file to be uploaded as the file upload target.

[0090] Specifically, the scenario traceability according to the file dependency path and the file upload target means using a Heterogeneous Graph Neural Network (HGT) to generate an upload traceability graph based on the file dependency path and the file upload target, and performing scenario traceability on the file to be uploaded according to the upload traceability graph.

[0091] Specifically, by using a heterogeneous graph neural network for scenario traceability, it is possible to determine the upload scenario by combining the file calls of the file to be uploaded and the dependency relationships between files, thereby improving the accuracy of scenario traceability and further enhancing the accuracy of subsequent security detection.

[0092] Specifically, generating a file configuration according to the file type, the file size, the file name, and the upload scenario data means aggregating the file type, the file size, the file name, and the upload scenario data into a file configuration. Directly applying for a format by the file to be uploaded may lead to potential security vulnerabilities, such as erroneously uploading large files and malicious files. Generating a file configuration facilitates the unified management and review of IOS-side security policies and permission controls.

[0093] Specifically, referring to Figure 3 As shown, applying for an upload format for the file to be uploaded according to the file configuration to obtain an upload domain name and an upload scenario value includes:

[0094] S31. Perform an upload security check on the file to be uploaded according to the file configuration to obtain a file check result;

[0095] S32. Extract the file size, file type, and upload scenario data from the file configuration respectively according to the file test result;

[0096] S33. Apply for an upload domain name for the file to be uploaded according to the file size and the file type to obtain an upload domain name;

[0097] S34. Apply for an upload scenario for the file to be uploaded according to the uploaded scenario data to obtain an upload scenario value.

[0098] Specifically, the security detection of the file to be uploaded according to the file configuration to obtain a file detection result includes:

[0099] Extract the file type from the file configuration, and split the file structure of the file to be uploaded according to the file type to obtain a local file set;

[0100] Extract file features from the local file set according to the file type to obtain a local file feature set;

[0101] Perform local security analysis on the local file feature set to obtain a local security score set;

[0102] Use a global attention mechanism to perform global dependency analysis on the local file feature set to obtain a feature dependency weight set;

[0103] Perform weighted summation on the local security score set according to the feature dependency weight set to obtain a global security score;

[0104] Perform configuration security analysis on the file configuration to obtain a configuration security score;

[0105] Calculate a file security score according to the configuration security score and the global security score;

[0106] Use a preset security threshold to perform security threshold verification on the file security score to obtain a file detection result.

[0107] Specifically, the splitting of the file structure of the file to be uploaded according to the file type to obtain a local file set means splitting the file to be uploaded into a local file set composed of multiple Patches according to the file type, where each local file in the local file set corresponds to a Patch. For example, when the file type is text, the file to be uploaded is split by paragraph, and when the file type is an image, the file to be uploaded is split according to a preset image grid size.

[0108] Specifically, the extraction of file features from the local file set according to the file type to obtain a local file feature set means selecting an encoder of the corresponding type according to the file type to extract the file features of each local file in the local file set. For example, when the file type is text, encoders such as BERT, XLNet, or RoBERTa can be used for file feature extraction. When the file type is an image, CNN structures such as VGG, ResNet, and DenseNet can be used for file feature extraction.

[0109] Specifically, the local security analysis refers to calculating the local security scores of each local file feature in the local file feature set by using a hidden Markov model or by means of feature matching in a preset malicious feature library.

[0110] Specifically, the global dependency analysis refers to calculating the dependency weights between each local file feature in the local file feature set by using a global attention mechanism. The weighted summation means multiplying each feature dependency weight in the set of feature dependency weights by the corresponding local security score in the local security score set, and summing the results of each product to obtain the global security score.

[0111] Specifically, the configuration security analysis of the file configuration to obtain a configuration security score means dividing the file configuration vector into file configuration features, and using these file configuration features and models such as Transformer to calculate the configuration security score corresponding to the file configuration features.

[0112] Specifically, the security threshold is a preset threshold for determining whether there are abnormal situations in the file to be uploaded. The security threshold verification means determining whether the file security score is greater than the security threshold. If so, the file detection result is set to test success. If not, the file test result is set to test failure.

[0113] Specifically, the file test result includes test pass and test failure. Extracting the file size, file type, and upload scenario data from the file configuration according to the file test result means that when the file test result is test pass, the file size, file type, and upload scenario data are extracted. When the file test result is test failure, the file upload is terminated.

[0114] Specifically, through upload security detection, efficient file security detection of uploaded files can be achieved, reducing security risks on the server side and ensuring data security.

[0115] Specifically, the upload domain name application refers to sending the file size and the file type to the server side, and the server side allocates an upload domain name for the file size and the file type. For example, when the file type is an image type, the corresponding upload domain name is the image server domain name.

[0116] Specifically, the upload scenario application refers to sending the upload scenario data to the server side, and the server side allocates an upload scenario value for the upload scenario data. For example, when the upload scenario data is user avatar data, the corresponding upload scenario value is profile image.

[0117] In the embodiment of the present invention, by performing an upload format application on the file to be uploaded according to the file configuration, an upload domain name and an upload scenario value are obtained, which can support the upload of files with file type and file size limitations in specific scenarios, and improve the flexibility of file upload.

[0118] S2. Generate an upload request according to the upload domain name and the upload scenario value.

[0119] Specifically, the upload request refers to a request for data upload sent by the IOS side to the server side that needs to be uploaded.

[0120] Specifically, the generating of the upload request according to the upload domain name and the upload scenario value includes:

[0121] Obtain a dynamic timestamp, and generate an upload address according to the dynamic timestamp, the upload domain name, and the upload scenario value;

[0122] Perform a request initialization operation according to the upload address to obtain an upload request.

[0123] Specifically, the dynamic timestamp refers to the timestamp of the current time when the IOS side initiates an upload request, usually presented in the form of a Unix timestamp, that is, the number of seconds or milliseconds from 00:00:00 UTC on January 1, 1970 to the current time.

[0124] Specifically, the method of string concatenation can be used to generate an upload address according to the dynamic timestamp, the upload domain name, and the upload scenario value. For example, when the upload domain name is https: / / example.com / upload, the upload scenario value is profile image, and the dynamic timestamp is time, these values can be concatenated to generate a complete upload address, and the upload address is https: / / example.com / upload?scene=profile image&time=timestamp.

[0125] Specifically, the application programming interface of AFNetworking can be used to perform a request initialization operation according to the upload address, that is, use the AFHTTPSessionManager of AFNetworking to initialize the request, and specify the address of the request as the upload address to obtain an upload request.

[0126] In the embodiment of the present invention, by generating an upload request according to the upload domain name and the upload scenario value, it is possible to support the upload of file types and file size limits in specific scenarios, improving the flexibility of file upload.

[0127] S3. Configure the upload content of the upload request according to the file to be uploaded and the file configuration to obtain a configured upload request.

[0128] Specifically, the configured upload request refers to the request data sent to the server side for file upload communication. In order for the server side to understand the file content of the file to be uploaded, the configured upload request includes data such as the request content and the upload address.

[0129] In the embodiment of the present invention, the step of configuring the upload content of the upload request according to the file to be uploaded and the file configuration to obtain a configured upload request includes:

[0130] Perform binary conversion on the file to be uploaded to obtain file data;

[0131] Initialize the download time limit, and extract the file name and file type from the file configuration respectively;

[0132] Configure the content of the upload request according to the file data, the download time limit, the file name, and the file type to obtain a configured upload request.

[0133] Specifically, the binary conversion refers to converting the file character type of the file to be uploaded into a binary format, and the bin function or the bytearray function can be used for binary conversion. The download time limit refers to the time period during which the server side can save and support download operations after the file to be uploaded is uploaded to the server side.

[0134] Specifically, fileData can be used to configure the content according to the file data, fileName can be used to configure the content according to the file name, and mimeType can be used to configure the content according to the file type.

[0135] Specifically, fileData, fileName, and mimeType are fields in the request content of the configuration upload request. fileData is the binary data of the file to be uploaded, representing the actual content of the file. fileData can be any type of data, such as images, audio, video, documents, etc. fileName is the name of the file, such as example.jpg or document.pdf. fileName is the identifier when the file is uploaded, used for server-side storage or display. mimeType is the MIME type of the file, representing the content type of the file. Common MIME types include image or jpeg for image types, application or pdf for PDF document types, and video or mp4 for video types.

[0136] In an embodiment of the present invention, by configuring the upload content of the upload request according to the file to be uploaded and the file configuration, it is possible to configure the request body data for the upload request to be made, thereby improving the integrity during file upload.

[0137] S4. Perform salted signature on the configuration upload request to obtain a signed upload request.

[0138] Specifically, the configuration upload request lacks verification content and may have security vulnerabilities, making the file to be uploaded vulnerable to attacks. Therefore, it is necessary to perform salted signature on the configuration upload request. Among them, the signed upload request includes data such as request headers, request content, and upload addresses.

[0139] In an embodiment of the present invention, performing salted signature on the configuration upload request to obtain a signed upload request includes:

[0140] Extract file data, download time limit, file name, and file type from the configuration upload request;

[0141] Perform data padding on the file data to obtain padded file data;

[0142] Perform data block splitting on the padded file data to obtain a set of file data blocks;

[0143] Perform non-linear operations, iterative confusion operations, and character splicing operations on each file data block in the set of file data blocks to obtain a file signature;

[0144] Extract a dynamic timestamp from the upload request and generate a dynamic salt string based on the dynamic timestamp;

[0145] Perform a character concatenation operation on the dynamic salt string, the file signature, the download time limit, the file name, and the file type to obtain a concatenated salt string;

[0146] Perform data signing on the configuration upload request according to the concatenated salt string to obtain a signed upload request.

[0147] Specifically, the data padding refers to padding the bit length of the file data to a multiple of 512, which can be achieved by padding zeros at the end of the file data. The data block splitting refers to splitting the padded file data into 512-bit file data blocks, and each file data block contains 16 32-bit words. Generating the dynamic salt string according to the dynamic timestamp means generating a dynamic salt value through character concatenation based on the dynamic timestamp and the unique identifier of the upload server.

[0148] In detail, the four-round non-linear function of the MD5 cache can be used for non-linear operations, and the methods of circular left shift and addition operations can be used for iterative confusion for the file signature.

[0149] In detail, performing data signing on the configuration upload request according to the concatenated salt string to obtain a signed upload request includes:

[0150] Perform secondary data padding on the concatenated salt string to obtain a padded salt string;

[0151] Perform secondary data block splitting on the padded salt string to obtain a set of salt string data blocks;

[0152] Perform Boolean operations, rotation iterations, and character concatenation operations on each salt string data block in the set of salt string data blocks to obtain a salt signature string;

[0153] Perform signature concatenation on the configuration upload request according to the salt signature string to obtain a signed upload request.

[0154] Specifically, the secondary data padding refers to padding the bit length of the concatenated salt string to a multiple of 32, which can be achieved by padding zeros at the end. The secondary data block splitting refers to splitting the padded salt string into multiple 32-bit salt data blocks.

[0155] In detail, eight 32-bit constant registers of SM3 can be used for Boolean operations. The rotation iteration refers to performing iterative confusion operations on each salt string data block after Boolean operations by using data shift and exclusive OR methods. The signature concatenation refers to concatenating the salt signature string as the signature of the configuration upload request in the request body.

[0156] In the embodiment of the present invention, by performing salted signature on the configuration upload request to obtain a signed upload request, it is convenient for the server side to implement signature verification of file data and request parameters, thereby effectively blocking external brute-force attacks.

[0157] S5. Perform file upload and upload verification on the file to be uploaded according to the signed upload request to obtain an upload result.

[0158] Specifically, the upload result includes upload failure and upload success.

[0159] Specifically, upload verification means that after uploading the file to be uploaded to the server side according to the signed upload request, verifying the signed upload request on the server side. After the verification on the server side passes, it is judged whether a file download link corresponding to the signed upload request can be obtained; if so, the upload success is used as the upload result, and a file download link corresponding to the signed upload request is generated; if not, the upload failure is used as the upload result.

[0160] In the embodiment of the present invention, by performing upload verification, it is possible to judge whether the signed upload is successful according to whether an upload result is generated, thereby improving the flexibility of file upload.

[0161] In the embodiment of the present invention, by applying for an upload format for the file to be uploaded according to the file configuration and generating an upload request according to the upload domain name and the upload scenario value, it is possible to support file uploads with specific scenario file types and file size limitations, improving the flexibility of file upload. By configuring the upload content of the upload request according to the file to be uploaded and the file configuration, it is possible to configure request body data for the upload request, thereby improving the integrity during file upload.

[0162] By performing salted signature on the configuration upload request to obtain a signed upload request, it is convenient for the server side to implement signature verification of file data and request parameters, thereby effectively blocking external brute-force attacks. By performing upload verification, it is possible to judge whether the signed upload is successful according to whether an upload result is generated, thereby improving the flexibility of file upload. Therefore, the file upload method based on the IOS side proposed by the present invention can solve the problem of low flexibility during file upload.

[0163] As Figure 4 shown, it is the device architecture diagram of a file upload device based on the IOS side provided by an embodiment of the present invention.

[0164] The file upload device 100 based on the IOS side described in the present invention can be installed in an electronic device. According to the functions achieved, the file upload device 100 based on the IOS side can include a format application module 101, a request generation module 102, a content configuration module 103, a salt-added signature module 104, and an upload verification module 105. The modules described in the present invention can also be referred to as units, which refer to a series of computer program segments that can be executed by the processor of an electronic device and can complete fixed functions, and are stored in the memory of the electronic device.
