摘　　要：为了克服传统指纹Fuzzy Vault算法在应用上的不足,提出了一种改进的Fuzzy Vault算法。主要采用一种新的多项式构造函数的方法来实现待保护密钥和指纹细节特征点的绑定,进而解决了传统Fuzzy Vault算法中密钥长度决定解码时需要匹配细节点个数的问题。实验结果表明,此方法进一步增强了算法的安全性和灵活性。In order to overcome the deficiency of the traditional Fuzzy Vault algorithm in the application,this paper proposed an improved Fuzzy Vault algorithm.It mainly adopted a novel polynomial constructor method to realize the cryptographic key and fingerprint minutiae data binding together,and then solved the problem that the matching minutiae number was determined by the length of secret in the traditional Fuzzy Vault algorithm in key decoding phase.The experiment results show that this method further enhances the security and flexibility of the algorithm.
