Method and system for generating two-dimensional codes according to selected code value intervals and designated information

Abstract

The invention provides a method for generating two-dimensional codes according to selected code value intervals and the designated information. The method comprises steps that according to the quantity of the generation-needing two-dimensional codes, code value intervals are divided in a code value database, and multiple pieces of code value information included by the code value intervals are ordered; each code value information of the code value intervals is extracted, and the extracted code value information is bonded with the designated information to form the bonded information; the bonded information is encrypted to form two-dimensional codes. The invention further provides a system employing the method. The system mainly comprises a code value interval division device, a code value extraction device, an association binding device, an encryption device and a two-dimensional generation device. Through the method, according to the quantity of the generation-needing two-dimensional codes, the code value intervals including the corresponding code value quantities are divided in the code value database, code value information storage vacancy in the code value database is continuously distributed, so the residual code value information of the code value database can be conveniently ordered.

Description

technical field [0001] The invention relates to a method for generating a two-dimensional code, in particular to a method and system for generating a two-dimensional code according to a selected code value range and specified information. Background technique [0002] At present, when generating a two-dimensional code, code value information sequentially extracted from the code value database is needed to generate a corresponding two-dimensional code from the code value information. However, when the number of two-dimensional codes to be generated is large, the pointer in the code value database may jump when extracting the corresponding number of code value information, and it is impossible to extract the corresponding number of code value information in a sequential order. After the value information is extracted, it will inevitably cause confusion in the code value information storage location in the code value database. Although the code value information storage space i...
