Abrégé

Provided are a two-dimensional code encryption method, a two-dimensional code transmission system and a storage medium. The two-dimensional code encryption method comprises: generating a first character string of a first system according to user information (S101); converting the first character string into a second character string of a second system by using a pre-set password book, wherein the pre-set password book is updated and replaced according to a pre-set period, and the base number of the second system is greater than that of the first system (S102); and generating a two-dimensional code by using the second character string (S103). The method can improve the security of access control of a shared space.
