摘　　要：基于数字图像的置乱与融合,提出一种新数字图像隐藏方法。对多幅数字图像采用先融合后置乱的处理,然后再基于DCT变换把置乱后的混合图像嵌入到公开图像之中。数值实验表明,所给方法实现简便,并且具有一定程度的鲁棒性。Based on digital scrambling and amalgamation, a novel digital image information hiding scheme is presented. In the scheme, multi-images were processed with amalgamation first then scrambling as reprocessing and post-processing, and the scrambled hybrid images were embedded into public images based on DCT transform. Numerical experiments shown that the scheme is simple in realization and is ro- bust to a certain extent.
