AFAIK Windows hello uses an array of IR sensors to map the contours of your face, which is why "a well printed photo" doesn't fool it. this on the other hand, is based on face recognition and identification in the video feed from your webcam.
- Boltgolt 4y agoIt really does not, it's simply identifying you from a picture: https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/windows-hello-face-authentication#how-it-works https://docs.microsoft.com/en-us/windows-hardware/design/dev... Notice how Microsoft shows how Hello can't be fooled by phones or by a picture. Howdy uses the same IR camera of course and thus would also not be fooled by that picture. Some (industrial) printers DO print in the IR-spectrum and can fool both.
- ohthehugemanate 4y agothank you! I learned a lot from this comment... including that it's possible to print the IR spectrum. Amazing.
