TWO-DIMENSIONAL BARCODE ENCRYPTION METHOD, TWO-DIMENSIONAL BARCODE TRANSMISSION SYSTEM AND STORAGE MEDIUM

摘要

A 2D barcode encryption method, a 2D barcode transmission system and a storage medium are provided. The method includes: generating a first character string of a first numeral system based on information of a user; converting the first character string into a second character string of a second numeral system using a preset codebook, wherein the preset codebook is updated according to a first preset period, and a base number of the second numeral system is greater than that of the first numeral system; and generating a 2D barcode using the second character string. Security of access control for a shared space may be improved.
