Biometria
In short
Biometrics uses unique physical or behavioural traits to identify a person. These measurements are used for security, such as unlocking a phone or entering a building.
In plain words
It is a way to prove who you are by looking at your body. Instead of a password, you use your fingerprint, face, or even the way you walk.
A simple example
When you hold your smartphone up to your face to unlock it, the device uses facial recognition biometrics to verify your identity.
Why it matters
It provides a much higher level of security than traditional passwords. Because your body parts are unique, it is very difficult for someone else to pretend to be you.
Easy to mix up
Do not confuse biometrics with cryptography, which uses mathematical codes rather than physical human traits.
