Biometric data: What if you “lost” your fingerprint?
Biometric authentication is becoming increasingly common. Smartphones and computers use it, banks have started to use it, and recently MasterCard began rolling out "selfie pay" allowing users to authenticate online payments by using their face at the point of sale. Biometric authentication refers to the validation of a user’s identity by measuring physical or behavioral characteristics. Biometric samples may include fingerprints, retinal scans, palm scans, face and voice recognition.
