| 摘 要： | 针对普通可视密码无法用于纸质载体的缺陷，提出一种用于纸质载体的改进可视密码，设计了基于改进可视密码的财务档案密级控制系统。由机密信息分割设备、秘密档案和蒙板印刷设备、秘密档案读取设备组成。机密信息分割设备将档案的秘密信息分割为两幅杂乱的分存图像。档案和透明蒙板印刷装置将一幅分存图像印刷在纸质档案上，将另一幅分存图像印刷到透明蒙板上。授权用户使用读取设备，将透明蒙板与档案秘密信息区叠合，借助读取设备的反射 LED 光读取秘密信息。具有安全、解密简单且不需计算机等优点。实验验证了该方案的可行性。

| Abstract: | Traditional visual cryptography (VC)cannot be applied to ordinary printed archives.To tackle this prob-lem,a modified VC system is designed,which can be applied to papers.Based on this modified VC system,a securi-ty level control system for archives of finance is constructed.This security level control system consists of three parts:secret sharing device,archive and mask printing device,and archive reading device.The secret sharing device is a computer system with embedded VC algorithm,which outputs two meaningless share images.The archive and mask printing device prints one share image onto the archive,and prints the other share image onto a transparent mask.Using the archive reading device,the authorized user can stack the mask with the archive.Using the reflected LED lights,the secret message can be recovered from the stacked area.The proposed system is perfectly secure and the deco-ding doesn’t involve any computers.We verified the validity of the proposed system through simulation and experiments. |
