Biometric Template Security Scheme using Fuzzy Vault

Purva Gabhane | Anisa Anjum ^[2]

Abstract: To protect the biometric templates and secret key simultaneously fuzzy vault is one of the most popular algorithms. In fuzzy vault generation at first, the preprocessing steps are applied and subsequently, the features are extracted and combined. For recognition, we match the feature vectors of images. The biometric template along with the input key are used to generate the fuzzy vault. In the decoding process, the template is given as input and is combined with the stored fuzzy vault to generate the corresponding final key. In this fuzzy vault scheme the biometric features are used to lock and unlock the secret key which is encoded in the coefficient of polynomial equation. The security of fuzzy vault system is depend on the infeasibility of polynomial reconstruction problem. By adding more noise points that are the chaff points to the vault enhance the performance of vault.
