Types of Biometric Authentication Methods
1. Facial Recognition: These systems use your face’s uniqueness to recognize you. Facial recognition is used on smartphones, in payment, and by police agencies.
2. Fingerprint: Fingerprint, which is unique to you, is used to verify that it is you. Fingerprint authentication can secure devices like phones and laptops, as well as cars and buildings. Fingerprint recognition is currently the most widely used biometric method in the world.
3. Eye Recognition: It uses unique patterns contained in the iris – the colored part or retina at the back of your eye to confirm that it is you (your iris or retina). Eye recognition has very high accuracy; however, it isn’t as popular due to its requirement for special infrared cameras and lighting. It is mostly found in places with high levels of security where extra precautions are needed.
4. Voice Recognition: Voice tone and distinctive intonation will ascertain who is speaking to you on this line. Voice recognition is mainly used for authenticating purposes when dialing customer service numbers such as those offered by banks.
5. Vein Recognition: This method of biometrics uses infrared light to visualize veins positioned beneath your hands or fingers. These vein patterns are distinct as fingerprints. Vein recognition is a great means of identifying an individual more accurately than even iris scans and retinal scans do. It works by shining an IR source onto your hand and using a camera to map out vein patterns beneath the skin surface. The approach is highly reliable since it is difficult for anyone to create or duplicate vein patterns.
What is Biometric Authentication?
Biometric authentication is a way to prove who you are by using parts of your body like your fingerprints, face, or eyes. It’s very difficult for someone else to copy or steal your biometrics like fingerprints. Passwords can be hacked, guessed, or stolen more easily. This article focuses on authentication techniques with the help of biometric systems and their various types.
