Biometrics Information Protection Using Fuzzy Vault Scheme
Ki Young Moon, Daesung Moon, Jang‐Hee Yoo, Hyun‐Suk Cho · 2012
Biometric based authentication can provide strong security for identifying the users. In addition, the security of biometric data is important, because most biometric data is not changeable in a lifetime. However, cancellable biometrics can stores a non-invertible transformed version of the biometric data. Namely, the biometric data is safely remained even if the storage is compromised. The cryptographic construction, called fuzzy vault, has recently been proposed. The fuzzy vault aims to secure critical data with the biometric template in a way that only the authorized user can access the secret by providing the valid biometric. In this paper, we propose three solutions for fuzzy fingerprint vault. First is more efficient fuzzy fingerprint vault with automatic alignment. Second solution can be resistant to correlation attack. Third is fuzzy fingerprint vault for OTP (One Time Template).
