Biometrics are very powerful, but if handled improperly, very dangerous. With great power comes great responsibility.
How do you prove that you are who you say you are? That’s the fundamental question underpinning so much of what we do online. Our answers are varied: Passwords. Numerical codes. And, increasingly, biometrics.
Biometrics are broadly defined as an aspect of someone’s body that is unique to them and very difficult — or even impossible — to reproduce. And while we’re most familiar with things like fingerprints and face scans, Avast’s Director of Trust Services, Drummond Reed, says that the category can also include a palm scan, DNA scan, typing pattern, walking pattern — even a photograph.
