Types of Biometric Analysis by Ashley Taylor https://padlet.com/200288286/kpnn60pzs9mw The CrimeLab en-us 2018-08-16 14:54:47 UTC 2026-02-24 17:19:09 UTC hello@padlet.com Fingerprint Recognition 200288286 https://padlet.com/200288286/kpnn60pzs9mw/wish/273501344 Fingerprint recognition technology has been done by taking a photograph of an individual's fingertips and record characteristics which include whorls, arches, and loops of the fingertip.

This technique also captures the patterns of ridges, furrows, and minutiae for an accurate analysis. This process can be done in 3 different ways: minutae based, correlation based, and ridge feature based. 

The fingerprint of a human being is a very secured, reliable, and stable biometric solution. Law enforcement agencies have been using this technology for decades to identify criminal. 

Currently, this technique is becoming popular in household security, banking, workforce management, etc.]]> 2018-08-16 15:03:56 UTC https://padlet.com/200288286/kpnn60pzs9mw/wish/273501344 Iris Recognition 200288286 https://padlet.com/200288286/kpnn60pzs9mw/wish/273504819 Many recognize Iris recognition as the best biometric technology for identification.

 It analyzes the iris characteristics including rings, furrows, and freckles that is situated in the colored tissue around the pupil. The iris scanner contains a video camera and works through glasses and even contact lenses.

Generally, iris recognition can be done by two methods: the Daugman System and Wildes System.

Iris recognition is used in many countries that are more crucial like border crossings, banking, private companies, institutes, law enforcement agencies, etc.

These measurements are broken into facial planes and retained in a database and then used for comparison.

The system then creates a template on the database for that person to compare the data for further uses.

As like signature recognition, it can also be categorized in two parts: static and dynamic.]]> 2018-08-16 15:39:08 UTC https://padlet.com/200288286/kpnn60pzs9mw/wish/273514096 Thermography Recognition 200288286 https://padlet.com/200288286/kpnn60pzs9mw/wish/273515475 Facial thermography uses Infrared cameras to capture the flow of blood beneath the skin of an individual. Then, the underlying pattern generates a robust biometric characteristic for positive identification.

This technology can be used to test “liveness” of an individual.
