#66 on the Evil Overlord list:
My security keypad will actually be a fingerprint scanner. Anyone who watches someone press a sequence of buttons or dusts the pad for fingerprints then subsequently tries to enter by repeating that sequence will trigger the alarm system.
Why not have the sequence remain the password, but also scan fingerprints? If you have the wrong fingerprints (username), the right password still won't work.

- espadrine 13y agoIf the scan doesn't leave collectable fingerprints on the keys, it'd work!
- roc 13y agoIf we assume the attacker is going to (be capable/mindful enough to) dust for fingerprints, they're going to get a very small potential keyspace for a passcode.
- unfamiliar 13y ago"fingerprint or pin" means that when the fingerprint scanner doesn't work, you can use the pin to unlock your phone. "fingerprint and pin" means that when the scanner stops working, you are locked out. Apple has obviously decided this is more of a risk/inconvenience than the extra security justifies.
- stephengillie 13y agoI keep forgetting that this discussion is iPhone-focused. At this point, I'm thinking about other systems too, such as ATM number pads or entry pads for security gate/secure door systems. What if each button on the ATM was also a very fast fingerprint sensor? (What if the ATM had a cleaning device built in?)
