摘要

Problem to be solved: to provide a two-dimensional code generation method capable of suppressing the capacity limit of the secrecy information, a two-dimensional code evaluation method, a two-dimensional code system, a two-dimensional code generating apparatus, a two-dimensional code evaluating apparatus, and a two-dimensional code.The two-dimensional code generation method comprises a fetch step, a generating step, a setting step, a switching step, and a two-dimensional code generating step.The generation step generates a data block containing the constituent code word based on the object information.In the setting step, based on the preset initial arrangement information, the layout information for arranging as the initial two-dimensional code is set for each of the plurality of code data included in the constituent code word.The replacement step switches the layout information set in the plurality of code data.The two-dimensional code generation step generates a two-dimensional code based on the layout information exchanged by the switching step.Diagram
