That reminds me of a thought I had recently. Often in movies and TV shows, someone will be torturing another for their secret information. And for some reason they always tell the truth. I've always wondered why movie characters don't lie more often in those situations. Because usually the torturer isn't in a position to confirm it's truth instantly, or sometimes at all. Passwords are the one exception to this. You can always confirm a password instantly from anywhere. But it doesn't need to be that way, you can have duress passwords. Truecrypt supports hidden archives, where entering the fake password unlocks a different encrypted folder with different files. The same thing thing is true on some "secure photo" apps for phones. For a phone, you would have a password that bricks the phone after a certain time limit, like 24 hours. But appears to work fine for the moment.
