Biometrics—like fingerprints, facial recognition, even voice patterns—are unique, measurable traits used to verify identity. First used in the 1880s by a French criminologist, biometric identification has come a long way. Today, it’s everywhere: unlocking phones, securing offices, and safeguarding sensitive data.
But as more companies adopt this tech for convenience and security, it’s important to remember it’s not flawless. Biometric systems can still be hacked, and they raise real privacy concerns. Smart, ethical implementation is key.
The questions around how safe and private this technology really is are growing along with its use. Click through the following gallery to explore the risks, the rewards, and what the future holds.
