Lets say someone took your fingerprints off a glass or a light-switch or your car, is there any reasonable way to prevent this?
Lets also say that you somehow become aware of them having a copy of your fingerprints and you remember that your phone requires your fingerprints to unlock; what do you do?
It's the fact that you can't permanently change your fingerprints nor restrict access to them which make them bad for authentication. Those two qualities also make them good for forensics.
- sunchild 15y agoIsn't that assuming that the system will accept a copy of a fingerprint? Are you telling me that I could easily spoof the fingerprint readers in immigration control simply by applying some kind of copies of another person's fingerprints over my own? Anyway, if copying fingerprints is possible, then they are useless for forensics, contrary to your final point.

Yes, it's pretty easy. However the immigration officer might notice. > Anyway, if copying fingerprints is possible, then they are useless for forensics, contrary to your final point. Well, it is possible to copy them, and they are not useless, therefor your conclusion has an error. And that error is that forensics does not require certainty, they require evidence. Evidence is probabilistic, and accumulating various forms of it can eventually be convincing, but each piece on its own is insufficient.
