BIOMETRICS
BIOMETRICS came from ancient clay tablets to unlocking your phone in 0.2 sec.
WHAT IS BIOMETRIC?
It means using physical or behavioral traits to prove it’s you. No password, no pin just your unique self doing the trick
ORIGIN OF BIOMETRICS
The first use of biometrics trace back to 500BC where Babylonians press fingerprints into clay contracts
1858: First modern fingerprints records for criminals in India
1963: first research paper from automated fingerprints matching by computer
1960s : first face recognition experiment started at Stanford/MT
THE BIG FOUR
The most used biometric and the popular are Face recognition, fingerprint, iris scan , and the voice recognition
* FINGERPRINT : This is the most used and most popular biometric system used by Gadgets and other services
how it works: Scan ridges/valleys on your finger. There no matching fingerprints. Not even for twin. It is fast, cheap and works 99% of the time
Used by Apple Touch ID,90% of smartphones, banks and police offices. It can fail if finger are wet/oily
* FACE ID/Face Recognition: How it works: project 30,000 invisible dots on your face to make a 3D map. It works the dark/ not in every cases.
It is hand free and hard to fake. It is 90% reliable. Used by Apple Face ID/ android devices, international identification, Meta/ facebook, and most banking services
* IRIS Scan: scans the colored ring of your eye. It’s like a fingerprint but for your eyeball. Extremely accurate, even better than fingerprints. Mostly used by Samsung smartphones and some high security facilities
* VOICE/BEHAVIORAL
Analyzes your voice pitch, typing speed or even how you walk. Suitable for phone calls, some banks use it for voice banking, also used by iPhone (Siri) and others
Other biometrics you may want to know.
Palm vein/ palm print :
scans the vein pattern inside your palm with infrared light. It’s hard to fake because vein are internal. It’s super secure and works even if hand is dirty
Hand geometry:
Measure the shape of hand, finger length, width and palm size. Good for verification not identification. Used by some old office, voting purpose and some banks
DNA: it uses your genetic code. Used by forensic, criminal investigators and paternity tests. It is 99.9% accurate
Retina scans: it is highly used by security facilities or govt labs. It scans blood vessels pattern at back of eye. Different from iris scanner.
People hate it because it requires close contact with scanners.
Others are Heartbeat/EcG,keystroke dynamics,gait analysis.
Face ID and fingerprints are the most used.
