A Fingerprint is a pattern of ridges and furrows located on the tip of each
finger. Fingerprints were used for personal identification for many centuries and the
matching accuracy was very high. Patterns have been extracted by creating an inked impression of
the fingertip on paper. Today, compact sensors provide digital images of these patterns.

3D Facial Recognition is a newly-emerging trend in facial
recognition software uses a 3D model, which claims to provide
more accuracy. Capturing a real-time 3D image of a person's
facial surface, 3D facial recognition uses distinctive
features of the face -- where rigid tissue and bone is
most apparent, such as the curves of the eye socket,
nose and chin -- to identify the subject. These areas
are all unique and don't change over time.

The IRIS of a human being has been historically recognized
to possess characteristics unique to each individual and so
the feature vector extracted from it also is also unique.
Iris scan biometrics exploits the unique characteristics
and feature vector of the human iris in order to identify
an individual.

The Palm Veins pattern is unique to every individual,
even among identical twins. Palms have a broad and complicated
vascular pattern and thus contain a wealth of differentiating
features for personal identification. Furthermore, it will not
vary during the person's lifetime. It is a very secure method
of authentication because this blood vein pattern lies under
the skin.

The Voice features of an individual's are based on physical characteristics such as
vocal tracts, mouth, nasal cavities and lips that are used in creating a sound. These
characteristics of human speech are invariant for an individual.Voice recognition distinguishes an
individual by matching particular voice traits against templates stored in a database. Voice
systems must be trained to the individual's voice at enrollment time.
