• Biometrics refers to the automatic identification of a person based on his/her physiological or behavioral characteristics

____________________________________________________

• The term "biometrics" is derived from the Greek words:bio (life) and metric (to measure).

• The earliest form of Biometrics appeared on the scene back in the 1800's. Alphonse Bertillon, a Parisian anthropologist and police desk clerk, developed a method for identifying criminals that became known as Bertillonage. Bertillonage was a form of anthropometry, a system by which measurements of the body are taken for classification and comparison purposes

HISTORY

• The Henry Classification system, named after Edward Henry who developed and first implemented the system in 1897 in India, was the first method of classification for fingerprint identification based on physiological characteristics

HISTORY(Contd.)

BIOMETRIC SYSTEM

WORKING

–The hardware captures the salient human characteristic

–The software interprets the resulting data and determines acceptability.

• FINGERPRINTS

• HAND GEOMETRY

• HAND WRITING

• IRIS

• RETINAL

• VOICE

• FACIAL

• most widely used and least expensive biometric technology

• A fingerprint is made of a series of ridges and furrows on the surface of the finger.

• Relatively high accuracy rate.

• Everyone is known to have unique, immutable (unchangeable) fingerprints.

FINGERPRINT DOOR LOCK

• Every hand is unique due to its length, width, and thickness.

• A scanner takes 90 measurements of the hand that are three-dimensional - all in just one second.

• The scanner then stores all this data

• A user writes a name or word on the screen of the PDA. Functions are provided to capture that handwriting, extract the relevant features, and compare two different samples

• Based on individual iris patterns.

• The iris, a thin interior eyeball membrane, is comprised of extremely complex patterns.

• Iris patterns are stable within a year of birth, and remain the same for life.

IRIS SCAN IMAGE

• Based on blood vessel patterns at the back of the eye.

• Captured by an individual looking through a reticule where a low-intensity light source is shone through the pupil to illuminate the retina.

• Voice recognition uses a neural net (relating to)

program to recognize your voice.

• Works on the physical characteristics of one’s voice.

• The user would dictate text fluently into the computer.

• Analyzes images of the human face for the purpose of identifying them.

• This program takes a facial image, measures the characteristics such as the distance between the eyes, length of the nose, and the angle of the jaw, and create a unique file called a template.

By the year 2007 biometrics had increased 100%.

APPLICATIONS• Criminal identification• Prison security• ATM• Aviation security• Database access
