I'm pretty sure that the information for a fingerprint scanner is already effectively a hash. It's a list of points that can be used to uniquely (more or less) identify the fingerprint. I doubt it's storing a photo.
But even then, what's the difference? If the hash is enough to identify you that's the important thing.
- zeckalpha 13y agoSomeone with just a hash can't impersonate you.
- stormbrew 13y agoNo, but they can identify you. The danger in the mass collection of biometric data is tracking. People who want to place prints or physically break into your phone are probably also present enough in your life to do it other ways.
- chrisdevereux 13y agoYeah, I was thinking about impersonating rather than identifying. Good point.
- Raphael 13y agoSalt the hash. Then it only has meaning to the phone.
