一种新的彩色图像视觉密码算法

New Visual Cryptography Algorithm For Colored Image

Sozan Abdulla

摘要:

视觉密码是一种特殊的图像加密技术,它将秘密图像分为多层。每一层都包含一些信息。接收器将层对齐,并且秘密信息通过人类视觉被揭示,而无需任何复杂的计算。所提出的算法是彩色图像,它提出了一个系统,其中采取四张图片作为输入,并产生三个图像,对应于四个输入图片中的三个。解码只需要选择这3个图像的某个子集,使它们重叠,并将它们堆叠在彼此的顶部,因此第四张图片通过将三张输出图像打印到重叠上并将它们堆叠在一起来重建。重建后的图像大小与原始图像大小一致。

英文摘要:

Visual Cryptography is a special encryption technique to hide information in images, which divide secret image into multiple layers. Each layer holds some information. The receiver aligns the layers and the secret information is revealed by human vision without any complex computation. The proposed algorithm is for color image, that presents a system which takes four pictures as an input and generates three images which correspond to three of the four input pictures. The decoding requires only selecting some subset of these 3 images, making transparencies of them, and stacking them on top of each other, so the forth picture is reconstructed by printing the three output images onto transparencies and stacking them together. The reconstructed image achieved in same size with original secret image.
