About :

For a few years now, it has been possible to unlock your phone simply by framing your face: this is facial recognition, a sophisticated technology that is also used for citizen security and is able to recognize a person's face through an image or a video frame. But why doesn't it work if we try to unlock our phone with our eyes closed or with sunglasses? And does the phone recognize us if we break our nose? In this video, we will analyze how facial recognition technology works, also trying to understand how it is used for airport security and other crowded places: spoiler, it feels like an action movie. 00:00 Intro 01:10 How facial recognition works on phones 01:51 How does the smartphone map the face: biometric data 03:08 Broken nose and aging: does the phone recognize us if our biometric data changes? 03:33 What happens if we break our nose? 03:56 What happens with aging? 04:35 The advantage of facial recognition: security 06:06 How secure is 2D facial recognition? 06:41 Why can't you unlock your phone with your eyes closed? 08:05 Other uses of facial recognition on mobile phones: photos and apps 9:00 Facial recognition and privacy: what are our rights 10:19 Facial recognition for citizen security: SARI CREDITS Tom Small RepresentUs #geopop #technology #facialrecognition
