摘　　要：基于用数字全息对图像进行置乱及复原的基本原理,提出了一种基于数字全息的图像置乱方法,并通过实验证明了本方法的置乱和复原效果.Image scrambling is an effective method for image encryption. A digital holography based method for digital image scrambling is presented. A digital image to be encrypted is hidden in a random fashion and then can be reconstructed by use of one random phase mask. The theory is described, and the utility of this method for image scrambling and reconstruction is verified by computer simulation.
