视觉加密（VC）是一种用于在分布式和共享图像（称为共享）中隐藏秘密图像的加密技术。VC方案用于将多个图像加密为无意义的、有噪的模式或有意义的图像。然而，使用一个唯一的份额解密多个秘密图像是困难的与传统的VC。我们提出了一种方法来隐藏多个图像在有意义的份额。我们可以使用一个公共共享同时解密多个图像，我们称之为amagic sheet。魔术表根据给定的份额解密多个秘密图像。这些份额被打印在胶片上，解密是通过物理叠加胶片来执行的。我们使用二进制，灰度和彩色图像评估所提出的方法。
Visual cryptography (VC) is an encryption technique for hiding a secret image in distributed and shared images (referred to as shares). VC schemes are employed to encrypt multiple images as meaningless, noisy patterns or meaningful images. However, decrypting multiple secret images using a unique share is difficult with traditional VC. We propose an approach to hide multiple images in meaningful shares. We can decrypt multiple images simultaneously using a common share, which we refer to as amagic sheet. The magic sheet decrypts multiple secret images depending on a given share. The shares are printed on transparencies, and decryption is performed by physically superimposing the transparencies. We evaluate the proposed method using binary, grayscale, and color images.
