基于混沌系统的图像隐藏技术

为了在保证隐藏信息不可见性的条件下，尽可能地提高隐藏图像信息的安全性与抗干扰性，提出一种基于混沌系统的图像隐藏技术．先利用Arnold变换与混沌系统产生的混沌序列对待隐藏图像进行加密预处理；然后利用Logistic混沌系统与图像分存技术把结果图像进一步隐藏起来；最后应用评价指标对隐藏效果和安全性进行分析．实验结果表明，该算法具有良好的安全性和隐藏效果．

To ensure the security and anti-disturbing of hiding image information under the conditions of visibility, An image hiding technology based on chaos systems was presented. Firstly, with the Arnold transform and the sequences generated by the chaos system, a hiding image was encrypted; then using Logistic chaos system and image sharing technique to hide the pre-encrypted image. The effect of hiding is also analyzed by using the method of accessing. Simulation results show that the algorithm has good safety and hidden effect.
