基于离散余弦变换和置乱融合模型的图像信息隐藏方法研究

Research on Image Information Hiding Method Based on DCT and Scrambling Fusion Model

为了保证在信息传输中的安全性问题,信息隐藏受到广泛的关注。论文提出了一种以图像作为载体,基于离散余弦变换和置乱融合模型的信息隐藏方法,可以有效地实现图像信息的隐藏。通过把岛屿和礁石图像作为载体,多种水面目标作为隐藏信息,对比实验验证了该方法的有效性。

In order to ensure the security of information transmission,information hiding has received widespread attention.This paper presents an information hiding method based on DCT and scrambling fusion model,which uses image as a carrier andcan accomplish information hiding efficiently.T hrough the experiment that images of island or reef are used as a carrier and varietiesof water targets as hidden information,the effectiveness of the method is validated.
