Abstract

The invention discloses an information hiding method based on the image complementation, and the method comprises the following steps of generating an original image; generating a complementary image corresponding to the original image; selecting a redundant image, transmitting the original image, the complementary image and the redundant image to a display device, and synchronously controlling a switch of switch spectacles; and utilizing the switch spectacles to filter the complementary image and the redundant image so as to observe the original image. The invention also discloses an information hiding system based on the image complementation. Due to the adoption of the image hiding method and system, a purpose for hiding the information can be well realized.

Description

technical field [0001] The present invention belongs to the technical field of image processing, and specifically relates to an information hiding method and system based on image complementarity. More specifically, the original image and its complementary image are displayed in two adjacent frames, and some redundant information frames are inserted. Synchronously switch glasses to select useful information frames and filter redundant information, so as to achieve the purpose of information hiding. Background technique [0002] With the rapid development of digital technology and informatization, digital image information has also become an important way of information transmission. The dissemination of a large amount of digital information has greatly changed the means of communication between people and provided unprecedented convenience for people's knowledge innovation. At the same time, information security has become a problem that people pay more and more attention to...
