Biometric Technology:
Biometric word consist of two word one is bio another is metric. Biometric simply
measures the human behavior physically. This technology analyzes the biological information of
the human being and uses it for surveillance purpose or for the access control. The verification
process using the biometric is gaining huge popularity in the public security and in the
commercial market as well. The biometric used in the daily basis by the human being like in the
office attendance system, airport’s security checkpoints, and several ID cards use biometric
databases as well in many countries.
Biometrics is of two types psychological and behavioral. The several parts of the
psychological biometrics are face recognition, fingerprint sensor, hand, iris sensor, DNA and the
behavioral are keystroke, signature, and voice recognition. These methods are used for collecting
human information to implement the biometric authentication.
4 biometric technologies are discussed below:
Fingerprint Recognition:
This technology takes finger print of a person and stores the features of the image
like the arches, loop along with the edges, whorls, furrows and minutiae. CCD or the CMOS
image sensors are used to capture the fingerprint. This technology adds another level of security
to the modern devices and the services (Sousedik & Busch 2014). It is the most economical
technology in the field of biometric it increases the security of the organization.
Face Recognition:
This is also one type of biometric application where the person can be identified
by his digital image by analyzing and comparing the face pattern. Many security systems use this
