摘 要：当前对于产品存储加密的要求越来越高，基于此提出了一种基于手指静脉的加密方案。首先，通过构建以白 tophat 转换和黑 top-hat 转换为主的滤波器用于提取手指静脉上的特征；然后，使用 k 阶 -Baker 映射对手指静脉上的特征进行加密，最后在仿真实验中，文中所提出的手指静脉加密算法在相关性方面和加密时间方面都具有较好的优势。

Abstract: Aiming at the increasingly high requirements for storage encryption of products at current, an encryption scheme based on finger veins is proposed. First, a filter based on white top-hat conversion and black top-hat conversion is constructed to extract the features on finger veins. Then, the features on the finger veins are encrypted using the k-order-Baker mapping. Finally, in the simulation experiments, the finger vein encryption algorithm proposed in this paper has better advantages in terms of correlation and encryption time.
Keywords: finger vein; encryption feature; safe storage
