提出一种基于(t,n)门限秘密共享方案和菲涅尔域迭代相位检索算法的新型多级认证系统，将迭代生成的第一相位分布分为n个部分并传递给n个不同的参与者，在高级认证过程中，可以收集其中的任意t(t≤ n)个或更多的相位分布来重构原始有意义的认证图像；而在低级别认证的情况下，任何t − 1或更少都不会获得认证图像的重要信息，但是，它可以在恢复图像和标准认证图像的非线性相关系数中产生显着的峰值输出，这可以成功地为高级别认证提供额外的认证层。理论分析和数值模拟都验证了我们提出的方案的可行性。
A new kind of multilevel authentication system based on the (t, n) threshold secret sharing scheme and the iterative phase retrieval algorithm in Fresnel domain is proposed, in which, the first phase distribution iteratively generated is divided into n parts and delivered to n different participants, during high-level authentication, any t (t ≤ n) or more of them can be collected to reconstruct the original meaningful certification image; While in the case of low-level authentication, any t − 1 or fewer will gain no significant information of certification image, however, it can result in a remarkable peak output in the nonlinear correlation coefficient of the recovered image and the standard certification image, which can successfully provide an additional authentication layer for the high-level authentication. Theoretical analysis and numerical simulations both validate the feasibility of our proposed scheme.
