Abstract

The invention discloses an information hiding method and device, and relates to the technical field of computers. A specific embodiment of the information hiding method comprises the following steps:carrying out block all-phase biorthogonal transformation on a carrier in which watermark information is to be embedded so as to embed the watermark information into a block DC coefficient obtained bytransformation; performing inverse all-phase biorthogonal transformation on the DC coefficient embedded with the watermark information to obtain a pixel block embedded with the watermark information;and obtaining an image embedded with the watermark information according to the pixel block embedded with the watermark information. According to the embodiment, the problems of identity recognition,link skipping, data hiding and visual sense brought to layout occupation of an existing two-dimensional code can be solved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an information hiding method and device. Background technique [0002] At present, QR codes penetrate into every corner of the mobile Internet, providing convenience for web page interaction and display of promotional pages. However, as a method of information hiding, QR codes are not effective information in themselves. The existence of QR codes will take up part of the layout, which is not a friendly interaction and will cause visual pollution to the original beautiful layout. In other words, the QR code is essentially a means of data encryption rather than valid data. The QR code usually placed on brochures or websites provides links to jump and follow others, which occupies the effective display area and affects the look and feel. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prio...
