Title:
TWO-DIMENSIONAL CODE GENERATION METHOD, TWO-DIMENSIONAL CODE DECODING METHOD, AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2019/095170
Kind Code:
A1
Abstract:
Disclosed are a two-dimensional code generation method, a two-dimensional code decoding method, and a terminal. The method comprises: encoding original information by using a first encoding mode to obtain encoded original information; encoding authentication information by using a second encoding mode to obtain encoded authentication information, wherein the first encoding mode is different from the second encoding mode; embedding the encoded authentication information into the encoded original information to obtain target encoded information; modulating the target encoded information to obtain a target bit stream; and converting the target bit stream into a two-dimensional code image according to a pre-set two-dimensional code generation algorithm. The implementation of the embodiments of the present invention can improve the security of a two-dimensional code.
