iPhone 5S: How Fingerprint Scanners Work
Fingerprint scanners - they're perhaps the most significant security feature to ever be put on a cell phone. How do they work and are they really as safe as they sound? Anthony has the answers.
How Fingerprint Scanners Work
"Computerized fingerprint scanners have been a mainstay of spy thrillers for decades, but up until recently, they were pretty exotic technology in the real world."
Your fingerprint at the scene of a crime doesn't prove anything
"We've all seen police dramas where triumphant suspects are appalled to learn that their fingerprint is on, say, the underside of the door handle of the victim's car. But what qualifies as a 'matching' print? And is the system always perfect, or does it make mistakes? Take a look at how incriminating your fingertips actually are."
The Boring and Exciting World of Biometrics
"Biometric identification has a faint whiff of the future about it, though what that future looks like depends entirely on your perspective."
How Fingerprinting Works
"Fingerprinting is one form of biometrics, a science that uses people's physical characteristics to identify them. Fingerprints are ideal for this purpose because they're inexpensive to collect and analyze, and they never change, even as people age."
Why do we have fingerprints?
"Fingerprints follow us our entire lives. Each little smudge singles us out as distinct individuals among billions of other human beings -- or at least that's what we've always been told."
Twins and Fingerprints
"Why do identical twins have different fingerprints? Why do we have fingerprints to begin with?"
