Biometrics (the field)

Biometrics is the technology and science of measuring and analyzing unique physical or behavioral characteristics of individuals for authentication and identification purposes. This includes traits like fingerprints, facial features, iris patterns, and voice recognition. Biometric systems are widely used in security, such as unlocking smartphones, accessing buildings, and verifying identities at airports. They offer a more secure alternative to traditional passwords and PINs since biometrics are unique to each person and harder to replicate. However, advancements raise questions about privacy and data protection, making the ethical use of biometrics an important topic of discussion.
