一种基于快速傅立叶变换的图像快速隐藏算法

A Fast Image Hiding Algrithm Based on Fast Fourier Transform

信息隐藏技术作为一种常用的数据保密技术,通过将有价值的数据隐藏于其它数据中来实现对数据的保护.给出了一种基于快速傅立叶变换的快速图像隐藏算法.数值试验表明该方法的隐藏能力较大,并保证了很好的视觉质量,且算法简单易行.

Information hiding is to conceal the existence of secret information. This paper proposes an image hiding algorithm based on Fast Fourier Transformation （FFT）. Our experimental results show the proposed method can embed a large amount of secret information while keeping a very high visual quality.
