An improved information hiding algorithm based on image

Image-based information hiding technology has been extensively studied in recent years. In order to ensure the security of information transmission, image information hiding technology must have the characteristics of transparency, security and robustness. In this paper, an improved image-based information hiding method is proposed, which utilizes the imperceptibility of the human eye to the change of color in a certain range and the difference in recognition ability of red (R), green (G) and blue (B). Adjusting the range of transformation according to the characteristics of each bit plane and color component value, and making changes in the range when embedding the binary information, so that information is hidden in most of the regions in the image. In addition, the method also scrambles the hidden information and randomly cuts the information when embedding. Experiments show that the new method has strong transparency, security and robustness.
