issues and concern of biometric

Authentication credentials such as fingerprint scans or voice recordings can leak from devices, from company servers or from the software used to analyze them. There is also a high potential for false positives and false negatives. A facial recognition system might not recognize a user wearing makeup or glasses, or one who is sick or tired. Voices also vary.

Human surveillance is major concern.

Government like china and five eyes group surveillance their citizens using biometric. 

In China who are against government will be traced down or even arrested using facial recognition.
