摘要
提出一种基于FFT和混沌的图像隐藏算法.首先利用混沌系统产生混沌序列对秘密图像进行加密,然后利用FFT与混沌序列把秘密图像隐藏到载体图像中.实验结果表明,该算法具有良好的安全性和隐藏效果.
An improved image hiding technology based on FFT and chaos is presented. We use one chaotic system to generate one chaotic sequences which are utilized to encrypt the secret image, then we use FFT and chaotic se- quence to realize the secret image hiding in the host image. Simulation results show that the algorithm has good se- curity and hiding effect.
