BIOMETRIC SYSTEM

Biometric refers to the automatic identification of a person based on her / his physical, psychological or behavioral characteristics

Physical biometrics

·       Finger print

·       Facial recognition

·       Iris scan

·       Hand geometry

·       Retina scan

Finger print recognition:

A live acquisition of person’sfinger prints

Dots(very small ridges)

Face recognition:

Capture image

Find face in image

Extract features

Compare features

Declare matches

Hand geometry:

Hand or finger geometry is an automated measurement of many dimensions of hand and fingers

Iris scanning:

Measure the iris pattern in coloured part of eye

Retina recognition:

Images of the back part of eye and there blood vesels matching with the sample

Speaker/voice recognition:

Voice recognition uses vocal characteristics to compare voice of a person with the sample saved

Signature recognition:

An automatic method of measuring an individual’s signatures

The technology determines speed ,direction, pressure of writing and the type the stylus is in the person’s hand

Keystroke dynamics:

Keystroke dynamics or typing dynamics refers to the automated method of identifying or confirming the identity of an individual based on the manner and the rhythm of typing on a keyboard. Keystroke dynamics is a behavioral biometric, this means that the biometric factor is 'something you do'

The technology examines such dynamics as speed and pressure total time taken to type a particular word and time elapsed between hitting certain keys
