The invention relates to a security protection technology, and discloses a file transmission method which comprises the following steps of: performing environment isolation on a user file, and performing file size verification on the user file; intercepting a file suffix name of the user file to perform suffix name verification on the user file; extracting a request uploading type in the file uploading request, and performing type verification on the user file according to the request uploading type and a file suffix name; determining a standard file header identification code according to the file suffix name, and performing content verification on the user file according to the standard file header identification code; and when the user file passes the file size verification, the suffix name verification, the type verification and the content verification, uploading the user file to a preset device by using a time sequence queue. In addition, the invention also relates to a block chain technology, and the user file can be stored in a node of a block chain. The invention further provides a file transmission device, equipment and a computer readable storage medium. According to the invention, the problem of low security during file transmission can be solved.
Description
technical field [0001] The present invention relates to the technical field of safety protection, in particular to a file transmission method, device, electronic equipment and computer-readable storage medium. Background technique [0002] With the rapid development of Internet technology, there is an increasing demand for uploading user files in Internet applications. For example, users can upload files containing recruitment information on a recruitment website. However, in order to prevent criminals from disguising virus files as normal file formats and uploading them to the application program, it is necessary to verify the actual format of the uploaded files to ensure the security of the transmitted files. [0003] At present, most methods of monitoring the actual format of the file are to verify the file extension and file size. However, due to the diversity of file types and the inconsistency of the content that needs to be verified for different types of files, the f...
