A New Method of Fingerprint Key Protection of Grid Credential

In this paper a novel method of biometric protection of private keys is consider. This method is based on enhanced Juels and Sudan ”fuzzy vault” scheme. Introduced algorithms utilize minutiae based fingerprint data for key locking procedures. It is proposed to include derived cryptographic primitive into special ≪biometric≫ extension of X.509.v3 certificates, which are used in grid environment authentication procedures.
