Does gait recognition (and body tics / unique movement style) not make this moot?

My sense is that facial recognition is a stop-gap and soon to be superseded, because the tech is there for more holistic 'reads' of a person - And that those subtle things that we humans can't see are actually plain as day and as clear as a fingerprint.

If we cover our face, then the data collected on gait etc. will be more than enough. If we adopt a different gait, then the data on other foibles and styles will then give us away. Etc. (we can't hope to disguise all of these at once)

A couple of years ago there were news articles that the pentagon has a "lasers that can identify people in a crowd from 200m away based on their heart rate signatures".

No idea if that's true or overblown, but it doesnt seem unlikely that such technology becomes possible in the future.

From where did they obtain your or my "heart signature"? What about gait, etc.?
