Security improvement in fingerprint authentication system using virtual biometric

Fingerprint authentication system faces a problem of security of patterns stored in database. In the proposed system a virtual fingerprint is created and stored in database instead of a single fingerprint. Two different fingerprints are used here. From the first fingerprint orientation is estimated and from second fingerprint certain minutiae points are extracted. They both are mixed to create a template which is encrypted and used as a virtual biometric. The system gives low rate and provides no stored information needed to recreate the fingerprint patterns.
