[0020] 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.

[0021] The embodiment of the present application provides a file upload method based on the IOS end. The execution subject of the file upload method based on the IOS end includes but is not limited to at least one of the electronic devices such as the server end, the terminal, etc. that can be configured to execute the method provided by the embodiment of the present application. In other words, the file upload method based on the IOS end can be executed by software or hardware installed on the terminal device or the 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 it can be a cloud server that provides cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (Content Delivery Network, referred to as CDN), and basic cloud computing services such as big data and artificial intelligence platforms.

[0022] Reference Figure 1FIG. 1 is a flowchart of a method for uploading files based on an IOS terminal according to an embodiment of the present invention. In this embodiment, the method for uploading files based on an IOS terminal includes: S1. Extract 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.

[0023] Specifically, the file configuration refers to the configuration information of the file, and the file configuration includes data such as file type and file size. The file type refers to the file type that needs 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 determine whether it meets the specific file size upper limit requirements.

[0024] In detail, the file to be uploaded refers to the file that needs to be uploaded. The file to be uploaded can be multimedia files such as images, videos and documents. 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.

[0025] Specifically, the upload scenario value is a further refinement and classification of the file upload scenario, which is used to distinguish different types of file upload requirements. The upload scenario value is usually a predefined string or number that identifies the specific upload purpose or business scenario. Through the upload scenario value, the server can provide personalized configuration 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 picture, 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.

[0026] In the embodiment of the present invention, refer to Figure 2 As shown, the step of extracting the file configuration from the file to be uploaded includes: S21, identifying the format of the file to be uploaded to obtain the file type; S22, performing size statistics on the file to be uploaded to obtain the file size; S23, extracting the name of the file to be uploaded to obtain the file name; S24, performing file dependency analysis on the file to be uploaded to obtain a file dependency path; S25, analyzing the upload target of the file to be uploaded to obtain the file upload target; S26, tracing the scene source of the file to be uploaded according to the file dependency path and the file upload target to obtain upload scene data; S27: Generate a file configuration according to the file type, the file size, the file name, and the uploaded scene data.

[0027] In detail, the format recognition refers to extracting the suffix of the file to be uploaded, and determining the file type according to the suffix. For example, the file type corresponding to the suffix jpg is the image type. The size statistics can be performed through the FileManager method or by directly reading the number of file bytes.

[0028] Specifically, the name can be extracted by querying the last component name in the local path of the file to be uploaded, and the scenario tracing refers to tracing the usage scenario corresponding to the upload operation of the file to be uploaded.

[0029] In detail, the file dependency analysis refers to extracting the API call path of the file to be uploaded and the dependency relationship between the various files called by the API, and the upload target analysis refers to extracting the upload target node of the file to be uploaded as the file upload target.

[0030] Specifically, the scene tracing according to the file dependency path and the file upload target refers to using a heterogeneous graph neural network (HGT) to generate an upload tracing graph according to the file dependency path and the file upload target, and tracing the scene of the file to be uploaded according to the upload tracing graph.

[0031] In detail, by using heterogeneous graph neural networks to trace the scene, the uploaded scene can be determined by combining the file calls of the files to be uploaded and the dependencies between the files, thereby improving the accuracy of scene tracing and further improving the accuracy of subsequent security detection.

[0032] In detail, generating the file configuration according to the file type, the file size, the file name and the upload scenario data refers to aggregating the file type, the file size, the file name and the upload scenario data into a file configuration. Directly applying for the format of the file to be uploaded may lead to potential security vulnerabilities, such as erroneous uploading of large files and malicious files. By generating the file configuration, unified management and review of IOS security policies and permission control are facilitated.

[0033] Specifically, refer to Figure 3As shown, the upload format application is performed on the file to be uploaded according to the file configuration to obtain the upload domain name and the upload scenario value, including: S31, performing an upload security check on the file to be uploaded according to the file configuration to obtain a file check result; S32, extracting the file size, file type and upload scenario data from the file configuration according to the file test result; S33, applying 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; S34: Apply an upload scenario for the file to be uploaded according to the upload scenario data to obtain an upload scenario value.

[0034] In detail, performing upload security detection on the file to be uploaded according to the file configuration to obtain a file detection result includes: Extracting a file type from the file configuration, and performing file structure splitting on the file to be uploaded according to the file type to obtain a partial file set; Extracting file features from the local file set according to the file type to obtain a local file feature set; Performing local security analysis on the local file feature set to obtain a local security score set; Performing global dependency analysis on the local file feature set using a global attention mechanism to obtain a feature dependency weight set; Performing weighted summation on the local security score set according to the feature dependency weight set to obtain a global security score; Performing a configuration security analysis on the file configuration to obtain a configuration security score; Calculate a file security score based on the configuration security score and the global security score; The file security score is verified using a preset security threshold to obtain a file detection result.

[0035] Specifically, splitting 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 consisting of multiple Patches according to the file type, wherein 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 into paragraphs, and when the file type is an image, the file to be uploaded is split according to a preset image grid size.

[0036] In detail, performing file feature extraction on the local file set according to the file type to obtain the local file feature set means selecting an encoder of a corresponding type according to the file type to extract 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 to extract file features. When the file type is an image, CNN structures such as VGG, ResNet, DenseNet can be used to extract file features.

[0037] Specifically, the local security analysis refers to calculating the local security score of each local file feature in the local file feature set by using a hidden Markov model or by using feature matching of a preset malicious feature library.

[0038] In detail, the global dependency analysis refers to using the global attention mechanism to calculate the dependency weights between the local file features in the local file feature set, and the weighted summation refers to multiplying each feature dependency weight in the feature dependency weight set by the corresponding local security score in the local security score set, and summing up the multiplication results to obtain the global security score.

[0039] Specifically, performing configuration security analysis on the file configuration to obtain a configuration security score refers to dividing the file configuration vector into file configuration features, and using the file configuration features and a model such as Transformer to calculate a configuration security score corresponding to the file configuration feature.

[0040] Specifically, the security threshold is a preset threshold for determining whether the file to be uploaded has any abnormal situation, and the security threshold check refers to 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.

[0041] In detail, the file test results include test pass and test fail, and extracting the file size, file type and upload scenario data from the file configuration according to the file test results means that when the file test result is test pass, the file size, file type and upload scenario data are extracted, and when the file test result is test fail, the file upload is ended.

[0042] Specifically, by performing upload security detection, efficient file security detection of uploaded files can be achieved, security risks on the server side can be reduced, and data security can be guaranteed.

[0043] In detail, applying for an upload domain name refers to sending the file size and the file type to the server, and the server allocates an upload domain name based on 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.

[0044] Specifically, the upload scene application refers to sending the upload scene data to the server, and the server allocates an upload scene value for the upload scene data. For example, when the upload scene data is user avatar data, the corresponding upload scene value is profile image.

[0045] In an embodiment of the present invention, by applying for an upload format for the file to be uploaded according to the file configuration, an upload domain name and an upload scenario value are obtained, so that file uploads with file types and file size restrictions in specific scenarios can be supported, thereby improving the flexibility of file upload.

[0046] S2. Generate an upload request according to the upload domain name and the upload scenario value.

[0047] Specifically, the upload request refers to a request for data upload sent by the IOS end to the server end where the data needs to be uploaded.

[0048] In detail, generating an upload request according to the upload domain name and the upload scenario value includes: Obtain a dynamic timestamp, and generate an upload address according to the dynamic timestamp, the upload domain name, and the upload scenario value; A request initialization operation is performed according to the upload address to obtain an upload request.

[0049] In detail, the dynamic timestamp refers to the timestamp of the current time when the iOS terminal initiates the upload request, which is usually presented in the form of a Unix timestamp, that is, the number of seconds or milliseconds from January 1, 1970 00:00:00 UTC to the current time.

[0050] Specifically, the upload address can be generated according to the dynamic timestamp, the upload domain name and the upload scene value using a string concatenation method. For example, when the upload domain name is https: / / example.com / upload, the upload scene value is profile image, and the dynamic timestamp is time, these values ​​can be concatenated to generate a complete upload address, which is https: / / example.com / upload?scene=profile image&time=timestamp.

[0051] In detail, the application program interface of AFNetworking may be used to perform a request initialization operation according to the upload address, that is, the request is initialized using AFHTTPSessionManager of AFNetworking, and the address of the request is designated as the upload address to obtain an upload request.

[0052] 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 files with file types and file size restrictions in specific scenarios, thereby improving the flexibility of file upload.

[0053] S3. Perform upload content configuration on the upload request according to the file to be uploaded and the file configuration to obtain a configuration upload request.

[0054] In detail, the configuration upload request refers to request data sent to the server for file upload communication. In order to enable the server to understand the file content of the file to be uploaded, the configuration upload request includes data such as request content and upload address.

[0055] 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 the configured upload request includes: Performing binary conversion on the file to be uploaded to obtain file data; Initialize the download time, extract the file name and file type from the file configuration respectively; The upload request is content configured according to the file data, the download time limit, the file name, and the file type to obtain a configured upload request.

[0056] In detail, the binary conversion refers to converting the file character type of the file to be uploaded into a binary format, and the binary conversion can be performed using the bin function or the bytearray function. The download time limit refers to the time period during which the server can save and support downloading after uploading the file to be uploaded to the server.

[0057] Specifically, the content may be configured according to the file data using fileData, the content may be configured according to the file name using fileName, and the content may be configured according to the file type using mimeType.

[0058] In detail, 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, indicating the actual content of the file, fileData can be any type of data, such as pictures, 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, which is used for server-side storage or display, mimeType is the MIME type of the file, indicating the content type of the file, common MIME types include image or jpeg for picture types, application or pdf for PDF document types, and video or mp4 for video types.

[0059] In the 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, the request body data can be configured for the request to be uploaded, thereby improving the integrity of the file when uploading.

[0060] S4. Perform salt signature on the configuration upload request to obtain a signed upload request.

[0061] In detail, the configuration upload request lacks verification content and may have security vulnerabilities, making the uploaded file vulnerable to attacks. Therefore, the configuration upload request needs to be salted and signed, wherein the signed upload request includes data such as the request header, request content, and upload address.

[0062] In the embodiment of the present invention, the step of performing a salted signature on the configuration upload request to obtain a signed upload request includes: Extract file data, download time, file name and file type from the configuration upload request; Performing data padding on the file data to obtain padding file data; Splitting the fill-in file data into data blocks to obtain a file data block set; Performing nonlinear operation, iterative obfuscation operation and character concatenation operation on each file data block in the file data block set to obtain a file signature; Extracting a dynamic timestamp from the upload request, and generating a dynamic salt string according to the dynamic timestamp; Performing 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; The configuration upload request is data signed according to the concatenated salt string to obtain a signed upload request.

[0063] Specifically, the data padding refers to filling the bit length of the file data to a multiple of 512, and the data padding can be performed by padding zeros at the end of the file data. The data block splitting refers to dividing the padded file data into 512-bit file data blocks, each of the file data blocks contains 16 32-bit words, and the generating of the dynamic salt string according to the dynamic timestamp refers to generating a dynamic salt value by character splicing according to the dynamic timestamp and the unique identifier of the upload server.

[0064] In detail, the four-round nonlinear function of the MD5 cache can be used to perform nonlinear operations, and the circular left shift and addition operations can be used to perform iterative obfuscation, the file signature.

[0065] In detail, the data signing of the configuration upload request according to the spliced ​​salt string to obtain the signed upload request includes: Performing secondary data padding on the spliced ​​salted string to obtain a padding salted string; Splitting the padded salt string into secondary data blocks to obtain a salt string data block set; Performing Boolean operations, rotation iterations, and character concatenation operations on each of the salted string data blocks to obtain a salted signature string; The configuration upload request is signed and concatenated according to the salted signature string to obtain a signed upload request.

[0066] Specifically, the secondary data padding refers to filling the bit length of the spliced ​​salt string to a multiple of 32, and the secondary data padding can be performed by padding with zeros at the end. The secondary data block splitting refers to splitting the padding salt string into multiple 32-bit salted data blocks.

[0067] In detail, the eight 32-bit constant registers of SM3 can be used for Boolean operations. The round-robin iteration refers to the iterative obfuscation operation of each salted string data block after the Boolean operation using data shifting and XOR methods. The signature splicing refers to splicing the salted signature string as the signature of the configuration upload request in the request body.

[0068] In the embodiment of the present invention, by performing salted signature on the configuration upload request to obtain a signed upload request, the server can conveniently implement signature verification of file data and request parameters, thereby effectively blocking external brute force attacks.

[0069] S5. Upload and verify the file to be uploaded according to the signature upload request to obtain an upload result.

[0070] In detail, the upload result includes upload failure and upload success.

[0071] Specifically, upload verification means that after uploading the file to be uploaded to the server according to the signed upload request, the signed upload request is verified on the server side. After the verification on the server side is passed, it is determined whether the file download link corresponding to the signed upload request can be obtained; if so, the upload success is taken as the upload result, and the file download link corresponding to the signed upload request is generated; if not, the upload failure is taken as the upload result.

[0072] In the embodiment of the present invention, by performing upload verification, it is possible to determine whether the signature upload is successful based on whether an upload result is generated, thereby improving the flexibility of file upload.

[0073] The embodiment of the present invention can support the uploading of files with file types and file size restrictions in specific scenarios by applying for the upload format of 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, thereby improving the flexibility of file uploading. By configuring the upload content of the upload request according to the file to be uploaded and the file configuration, the request body data can be configured for the request to be uploaded, thereby improving the integrity of the file when uploading.

[0074] By performing salted signature on the configuration upload request to obtain a signature upload request, the server can conveniently implement signature verification of file data and request parameters, thereby effectively blocking external brute force attacks. By performing upload verification, it is possible to determine whether the signature upload is successful based on whether an upload result is generated, thereby improving the flexibility of file upload. Therefore, the file upload method based on the IOS end proposed by the present invention can solve the problem of low flexibility when uploading files.
