| 摘 要： | 介绍了基于Arnold置乱变换和离散余弦变换(DCT)的图像信息隐藏算法.首先对秘密图像进行Arnold置乱变换,形成秘密信息,然后对载体图像进行DCT变换,秘密信息通过量化处理嵌入到DCT域中.从试验结果来看,该算法在一定程度上满足了信息隐藏的鲁棒性要求.

| Abstract: | In the paper,a data-hiding algorithm in image based on Arnold transformation and discrete cosine transform(DCT) is introduced.First Arnold transformation is used for secret image,then DCT transformation is used for original image and hiding bit is embedded in DCT by quantizing process.From the result of the experiment,this algorithm meets with the requirement of the information hiding robustness to a certain extent. |
