Speaking of passwords, or: how I detest them so... Passwords ... other people can watch you enter them, even at distance, and are easily forged, once known. Pen & ink signatures ... the results can be replicated and are hard to verify algorithmically. Other solutions ... meh. Hand gesture inside a box, more inventive than the bird, determined by cameras. 3D gestures like if android unlock worked in augmented reality. The "box," not of the Dune kind, would start folded flat and open to be sure nothing else were inside of it. Sadly, not even Thing. Folds up to create a completely discrete puppetry stage for god knows what, but sadly it wouldn't be all that interesting. The point being that it's harder to fake or compel a performance that would basically be impossible to observe (assume trust of the system, of course, like anything... imperfect) rather than something tangible like an iris, print, voice, etc. I'm sure the DDR ATM will be next at airports, but passwords still suck.
