ABSTRACT
A biometric system is a recognition system, which makes a personal
identification by determining the authenticity of a specific physiological or
behavioral characteristic possessed by the user. This method of identification
is preferred over traditional methods involving passwords and PIN numbers for
various reasons:
·
The person to be identified is
required to be physically present at the point of identification.
·
Identification based on
biometric techniques eliminates the need to remember a password or carry an
identity.
But it has its own disadvantages;
Behavioral traits such as voice and signature are vulnerable to spoof attacks.
Introduction:
The prominence and acceptance of
biometric technologies such as fingerprinting, facial recognition, hand
geometry, and iris recognition may leave little demand for other modalities.
However, the emerging vein-pattern recognition technology, with its own unique
features and advantages, has maintained its position against the others.
The up-and-coming biometric
technologies include vein, DNA, ear, and body odor recognition. Of these, vein
pattern recognition is gaining momentum as one of the fastest-growing
technologies. It is on course to become the newest entrant to mainstream
biometric technologies, moving from the research labs to commercial deployment.
