摘要
通过对秘密图像和环形共享份进行纵向区域分割,该文提出了相关矩阵组,并在此基础上设计了一种新的多秘密视觉密码方案。与现有的多秘密方案相比,该方案不仅实现了加密任意数量的秘密图像,而且在像素扩展度和相对差等方面有明显改善。
Based on the correlative matrices,which are designed by dividing secret images and shares into vertical areas,a new multi-secret visual cryptography scheme is presented in this paper. Compared to the previous ones,the proposed scheme makes the number of secret images not restricted and has obviously improved the pixel expansion and the relative difference.
