Abstract: Traditional biometric schemes used master copy minutiaefor authentication. The enrollment and verification process carried out through the same master copy minutiae. However, the protection of biometric template is more crucial as the number of minutiae compromise will be occurred. In this paper, an improved secret sharing scheme for biometric authentication using finite field is proposed. The master copy of biometric template is transformed into finite field for masking minutiae information. The concept of secret sharing is employed to split the template into multiple copies and maintained between smart card and public consortium. This approach allows perfect biometric authentication for operating smart cards with high-level security.
