摘要/Abstract

摘要： Fuzzy Vault算法的安全性主要依赖于指纹模板的安全性以及上锁算法的复杂性。利用可变参数的函数式对原始指纹特征值进行数学变换，生成随机的指纹特征值。同时通过密钥拆分的方法形成多模糊金库，使得多用户共同管理金库，实现了指纹模板的可撤销性，从而提高了原有模糊金库算法的安全性能。

关键词: 指纹, 可变参数, 多模糊金库, 可撤销性, 密钥拆分

Abstract: The security of Fuzzy Vault algorithm depends on the fingerprint template and the locking algorithm. By using the functions with variable parameters to transform the original values of fingerprint characteristics, a random value of fingerprint characteristic was generated. Also the multi-fuzzy vaults were formed by the key separation which allows more users to manage the fuzzy vaults together. Thus, the revocability of the fingerprint template was achieved and then the security of the original algorithm was improved.

Key words: variable parameters, revocability, key separation, muti-fuzzy vault, fingerprint
