In fact, recognising a face is only the first step of biometric surveillance, he suggests. “It’s really like an entry-level term to much broader, deeper analysis of people’s biometrics. There’s jaw recognition — the width of your jaw can be used to infer success as CEO, for example. Companies such as Boston-based Affectiva are doing research that analyses faces in real time, to determine from a webcam or in-store camera if someone is going to buy something in your store.”
Other analyses, he adds, can be used to determine people’s tiredness, skin quality and heart rate, or even to lip-read what they are saying. “Face recognition is a very deceiving term, technically, because there’s no limit,” he concludes. “It ends ultimately only with your DNA.”
