The Fear of Biometric Technology in Today's Digital World

In the age of information technology, more and more people--young and old alike–don't have problems sharing their personal information online, sometimes, even private ones. And it seems like there's no big deal when it comes to biometric identity, either. Every day, people from all over the world use facial or fingerprint recognition to unlock phones and log in to apps and games. They also want to be tagged in friends' photos, enabled by identification algorithms used by Facebook and Google. From employee IDs to national IDs, to digital and airport security, biometric identification and authentication are proliferating. The biometric signatures of a person characterize their physiological or behavioral characteristics.
