Data secure transmission method and device, equipment and medium

The invention discloses a data security transmission method and device, equipment and a medium, and relates to the technical field of data security. The method comprises the following steps: when a terminal scans a specified two-dimensional code, entering an information reporting page corresponding to the two-dimensional code, and executing a data input operation on a page at the front end of a server; the server front end judges whether a rule base exists or not, and when the terminal executes data submission operation, the server front end intercepts all requests, processes data of each interface based on the rule base and then sends the processed data to the server rear end; uniformly intercepting all interface requests by the back end of the server, acquiring request parameters, and realizing corresponding automatic decryption adaptation based on the rule base, so that the application framework is non-inductive to interception and decryption; and performing security level judgment on the decrypted data ba
