Sensitive information anti-interception safety transmission method and system

Abstract

The present invention provides a sensitive information anti-interception safety transmission method which comprises: S1, a client generates a random ordering rule of all keyboard characters according to a first algorithm and the keyboard characters are arranged according to the random ordering rule; S2, the server generates an identification table, wherein all the keyboard characters and identifications corresponding to the keyboard characters are stored in the identification table; S3, the client acquires keyboard characters to be transmitted according to sensitive information input by a user, acquires the identifications corresponding to the keyboard characters to be transmitted for the server and generates identification information; S4, the identification information is encrypted to generate a first ciphertext and the first ciphertext is sent to the server; and S5, the server receives and decrypts the first ciphertext, acquires the identification information, analyzes out the identification according to the identification information, inquires and extracts the keyboard characters corresponding to the identification by the identification table and acquires the sensitive information input by the user.
