Among all the biometric techniques, fingerprint-based identification is the oldest
method which has been successfully used in numerous applications. Everyone is
known to have unique, immutable fingerprints. A fingerprint is made of a series of
ridges and furrows on the surface of the finger. The uniqueness of a fingerprint can be
determined by the pattern of ridges and furrows as well as the minutiae points.
Minutiae points are local ridge characteristics that occur at either a ridge bifurcation
or a ridge ending. Minutiae are very important features for fingerprint representation,
and most practical fingerprint recognition systems only store the minutiae template in
the database for further usage. The conventional methods to utilize minutiae
information are treating it as a point set and finding the matched points from different
minutiae sets. In this virtual minutiae is used for fingerprint recognition, in which the
fingerprint’s orientation field is reconstructed from virtual minutiae and further
utilized in the matching stage to enhance the system’s performance. A decision fusion
scheme is used to combine the reconstructed orientation field matching with
conventional minutiae based matching. Since orientation field is an important global
feature of fingerprints, the proposed method can obtain better results than
conventional methods. In our paper it is implemented using ‘MATLAB’ and
considering the virtual minutiae.
