Two-dimensional code, and generation method and identification method thereof

Abstract

The invention provides a two-dimensional code. The two-dimensional code comprises a plaintext information part and a ciphertext information part, wherein the plaintext information part is used for downloading address information for APP (Application) identification software used for analyzing the two-dimensional code; the ciphertext information part comprises enciphered information which is enciphered and consists of a character or a plurality of identical characters. A method for generating the two-dimensional code comprises the following steps: setting the application range of the two-dimensional code; inputting information contents needing to be enciphered, and converting the information contents into character string information of corresponding positional notation; enciphering the character string information to form the enciphered information; combining the mark number of application range identifier information, the mark number of enciphered mode instruction information and the enciphered information into the ciphertext information part; generating the two-dimensional code through the plaintext information part and the ciphertext information part. The plaintext information part can remind a user to download and install special two-dimensional code APP identification software used for analyzing the ciphertext information part so as to acquire the information contents corresponding to the ciphertext information part.

Description

technical field

[0001] The invention relates to the field of two-dimensional codes, in particular to a two-dimensional code and its generation method and identification method. Background technique

[0002] A two-dimensional code is a black and white pattern distributed on a plane (two-dimensional direction) according to certain rules with specific geometric figures. However, since any existing two-dimensional code APP recognition software can read and analyze the two-dimensional code, it is easy to cause information leakage. Contents of the invention

[0003] Aiming at the deficiencies in the above problems, the present invention provides a special two-dimensional code APP recognition software that can be downloaded and installed according to the prompt information when reading the two-dimensional code, thereby parsing out the two-dimensional code and the two-dimensional code. A two-dimensional code of information corresponding to the code, a generation method and a reco...
