Abstract

The embodiment of the invention discloses a two-dimensional code information hiding method and device, an electronic device and a storage medium, and belongs to the technical field of computers. The method comprises the steps of obtaining an initial two-dimensional code graph and the to-be-hidden information; performing corresponding frequency domain signal conversion processing on the two-dimensional code graph according to a preset frequency domain signal conversion model to obtain a converted frequency domain signal; and converting the converted frequency domain signal into a correspondinggraphic symbol, and storing the hidden two-dimensional code information in the corresponding graphic symbol in a superposition manner. According to the scheme, hiding of the two-dimensional code information can be truly and effectively achieved, the hidden two-dimensional code information is hidden in the frequency domain information, and the hidden two-dimensional code information is not prone tobeing cracked.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a method, device, electronic equipment and storage medium for hiding two-dimensional code information. Background technique [0002] Two-dimensional code technology has become the most important hot technology in the development of technologies and applications such as automatic identification technology and commodity identification, mobile marketing and product traceability. Two-dimensional code technology, especially the matrix two-dimensional code represented by Hanxin code and QR code, is essentially a special structured graphic that can distinguish the two-dimensional code from other two-dimensional codes. It consists of a characteristic graphic frame with macroscopic features and a sequence or combination of data modules distributed in the graphic frame with specific information arrangement and coding definitions. The data acquisition method...
