"2. Install a camera anywhere I work and focus it on my hands"
I feel like we need to be talking about this more. For all the hullabaloo concerning password strength and encryption key length, MANY of our secret key entry methods would be quite easily defeated by a common webcam and a pair of human eyeballs.
That's kind of scary! It's not about to make me stop using passwords, but it is going to make me stop and think before I log into anything in a coffee shop.
It's even worse than that. Recent studies have been able to reproduce the text you type by analyzing the sounds emitted by the keyboard[1] and even the ripples produced in the local wifi signal.[2]
I always thought that conclusion was the reason the "encryption wars" ended in the USA, and the subsequent removal of encryption from being an export controlled "munition".
Forget breaking strong encryption, far easier to use a camera, key logger, or other means of "spy craft".
