From my understanding, one of the tricky bits of biometrics as passwords in general is that you can't really change them. What happens when the future's equivalent of an ATM skimmer scans your iris?
Could also lead to increased violence in muggings/robberies, etc. If fingerprints or eyes become necessary to access what it is they want to take, they'll just add those to the list of things to take from you.
- screaminghawk 10y ago>one of the tricky bits of biometrics as passwords Serious question, would a passport be considered a password in this context? >ATM skimmer scans your iris Your credit card is authentication but your PIN is authorization. I imagine your iris will replace your card, not your PIN. The difference between authentication and authorization can be confusing in some real world examples.
- rfrank 10y agoInteresting point re: authentication vs. authorization. In the situation of an iris scan as authentication, what then becomes the authorization? Multi-factor biometrics, some sort of 2/3/4fa scan? Broadly speaking, solutions to that problem which involve more biometric data make me uncomfortable, in no small part because I just don't trust the people who operate the systems. Don't know on the passport thing, although my gut says no. Do you mean people just having a passport in general, so say an iris scan pulls your passport data & cross references it against a camera at the ATM? Or having it physically on you so its RFID chip is read? I've just started thinking/learning about these sorts of problems, so as of now I don't have many opinions on how things should be done haha.
