Biometrics can be defined as the technique of studying the physical characteristics of a person such as fingerprints, hand geometry, eye structure etc. to establish his or her identity. This science is primarily implemented to identify individuals.
DISCOVERY OF BIOMETRICS :
In 1880 by Henry Faluds in Japan.
He studied the prints left behind by
craftsmen on ancient clay fragments.
He study his own and his colleague’s
fingerprints.
*Each individual had unique fingerprints.
Principle of fingerprint scanner:
heart of scanner is CCD, light sensor system same as that of digital camera.
* generate electrical signal in response of light.
* Electrial signal converted into digital . representation of image.
Voice biometrics:
Voice is unique to each person
Voice print generated is characterised by vocal tract.
User repeats a line or a sequence of numbers.
Audio capture devices are used microphones, phones etc.
