摘要
提出一种新的彩色可视密码方案.该方案把一幅图像秘密地分割成n幅共享图像,分发给n个参与者,使得授权子集中的所有参与者合作能够恢复秘密图像,而任意非授权子集却得不到有关秘密图像的任何信息.其中,每个共享图像与秘密图像有着同样大小,而且恢复图像和秘密图像完全一样,没有任何失真.该方案实现简单,安全有效,能适用于任意彩色数和任意接入结构上的可视秘密共享.
This article proposes a new color visual secret sharing scheme. The scheme allows encoding an image into n shared images distributed to n players, so that only qualified subsets of these players can recover the secret image, but any unqualified subsets of them gain no information about the secret image. Where each shared image has the same size as the secret one, and the recovered image is as same as the secret one such that there is no loss of the secret. It is secure, efficient and simple to implement the scheme, which fits to share any color images for general access structure.
