| 摘 要： | 视密码学的可视分存方案仅关注权重相同的参与者，忽略了原图主次信息的区别，造成了方案应用的局限性．为解决该问题，构建更具适用性、一般性的可视分存方案，提出了一种基于一般存取结构的可视分存方案，并进行扩展，进一步提出了基于权重的可视分存方案．该方案生成的图像与原图相比几乎没有任何失真，适用于黑白、灰度、彩色等各类图像的秘密共享．

| Abstract: | The visual cryptography schemes presented nowadays just restrictedly considered the participants have the same weight,and omit the deference between primary information and secondary one in image.It may lead to the limitation of practical applications.In order to solve the above questions,and construct the more applicable and universal VCS,this paper firstly presents(k,n)-Threshold VCS for general access structure,and then extends it to(k,n)-Threshold VCS based on Participant's weight.This scheme produces t... |
