By Professor Fraser Sampson, former UK Biometrics & Surveillance Camera CommissionerAs we look to facial recognition and other biometrics to solve social problems, an age-old challenge keeps resurfacing. As advanced biometrics like facial recognition and gait analysis are used to tackle crime, the question remains relevant today. Lumping criminals together is highly dubious but the idea of being born bad continues to find support. It sounds impressive, however diagnosing criminality from physiology has some basic hurdles and they’re as much about the crime as the criminal. Biometrics attribute identity to criminals rather than identifying attributes of criminality.
