Improved Fuzzy Vault fingerprint encryption scheme
一种改进的指纹Fuzzy Vault加密方案

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.
