INTRODUCTION
✴ The term “biometrics” is derived from the Greek words “bio” (life) and “metrics” (to measure).
✴ Biometrics is the technical term for body measurements and calculations.
✴ Biometrics is the measurement and statistical analysis of people’s unique physical and behavioral characteristics.
✴ Biometrics allows a person to be identified and authenticated based on a set of recognizable and verifiable data, which are unique and specific to them.
✴ Biometrics authentication is the process of comparing data for the person’s characteristics in order to determine resemblance.

TYPES OF BIOMETRICS
Biometrics Can Be Divided Into Three Main Categories Of Characteristics:
1. BIOLOGICAL
2. MORPHOLOGICAL
3. BEHAVIORAL
⏩DNA MATCHING
The identification of an individual using the analysis of segments from DNA.
👂EAR
The identification of an individual using the shape of the ear.
👀EYES – IRIS RECOGNITION & RETINA RECOGNITION
👁IRIS RECOGNITION- The use of the features found in the iris to identify an individual.
👁RETINA RECOGNITION- The use of patterns of veins in the back of the eye to accomplish recognition.
👱♂️FACE RECOGNITION
The analysis of facial features or patterns for the authentication or recognition of an individuals identity.
🤘FINGERPRINT RECOGNITION
The use of the ridges and valleys (minutiae) found on the surface tips of a human finger to identify an individual.
👋FINGER GEOMETRY RECOGNITION
The use of 3D geometry of the finger to determine identity.
🤚HAND GEOMETRY RECOGNITION
The use of the geometric features of the hand such as the lengths of fingers and the width of the hand to identify an individual.
🙌VEIN RECOGNITION
Vein recognition is a type of biometrics that can be used to identify individuals based on the vein patterns in the human finger or palm.
👃ODOUR
The use of an individuals odour to determine identity.
✍SIGNATURE RECOGNITION
The authentication of an individual by the analysis of handwriting style, specifically the signature. Technology is available to check two scanned signatures using advances algorithms.
👩💻TYPING RECOGNITION
The use of the unique characteristics of a persons typing for establishing identity.
🗣VOICE / SPEAKER RECOGNITION
There are two major applications of speaker recognition:
🙊Voice – Speaker Verification / Authentication
🙊Voice – Speaker Identification
✔In forensic applications, it is common to first perform a speaker identification process to create a list of “best matches” and then perform a series of verification processes to determine a conclusive match.
✔Voice recognition analyzes audio input for specific patterns in speech or sound. Each voice, or common noise, has a recognizable wavelength pattern that can aid in identification of a specific individual.
🚶♀️👣GAIT
The use of an individuals walking style or gait to determine identity.
