So then its probably a pretty good idea to randomize the number keypad for the lock screen, which I do. Does this defeat that, I can't think of a way it does..

The paper focused on an attack against a payment system, not the lock screen, so you'd need to randomize every password input keyboard at the system level.

Probably not a bad idea...

Another option would be to use thumbprints for all authorizations after the device is unlocked.

How do you randomize the keypad? Is it possible on iPhone?
