Abstract

The invention discloses an information hiding method and device and a computer storage medium, relates to the technical field of information processing, and solves the technical problem of low confidentiality of hidden information. The information hiding method comprises the following steps: acquiring a first image and a second image; processing the first image through a frequency domain algorithm to obtain a grey-scale map; carrying out gray processing on the second image according to the gray-scale map, and carrying out sub-affine transformation scrambling on the image subjected to the gray processing to obtain a third image; and embedding the third image into the grey-scale map, and obtaining a fourth image hiding the second image through a frequency domain reduction algorithm.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an information hiding method, device and computer storage medium. Background technique [0002] Information hiding refers to the use of human perception and the redundancy of digital media to embed secret information into the carrier to track the use of the carrier, so as to achieve the purposes of copyright protection and integrity authentication. [0003] Among the information hiding algorithms in the prior art, the frequency domain algorithm is more robust and can prevent the watermark failure caused by the destruction of the picture. The information hidden by the frequency domain algorithm is easy to be displayed, and the confidentiality of the hidden content is low. [0004] Therefore, those skilled in the art are devoting themselves to developing an information hiding method, device and computer storage medium that can improve the confidentiality of hidden ...
