摘　　要：研究混沌序列在数字图像隐藏中的应用。由于混沌序列具有易生成性、对初始条件强敏感性、可完全重现性等特点,从而保证了图像隐藏算法的安全性。算法同时采用两种不同的混沌序列,实现对数字图像的快速隐藏。实验证明,该算法具有较高的效率、较好的隐藏与恢复效果和很好的抗剪切功能。The application of chaotic sequence in digital image hiding algorithm is studied. Because of the features of easy generation, strong sensitivity to initial conditions and complete reappearance the chaos sequence possesses, the security of the image hiding algorithm is ensured. There are two different chaotic sequences employed by the algorithm to realise fast hiding of the digital images. The simulative ex- periment shows that the algorithm has high efficiency, quite good hiding and resuming effects, as well as the anti-aggressivity to shear transformation attack.
