Keystroke mechanics keep being talked about as a form of biometric identification. I’m still skeptical because of how variable this can be…
I live in Iowa which means we have some pretty cold winters. I certainly do type differently if I have cold fingers.
I also type vastly differently depending on my level of inebriation (of course, this can cause regular typos in passwords anyway…)
I type differently depending on my position and mood and keyboard and life. I type far differently now than I did 5 years ago, for instance. Sometimes I am in thought and might type differently, especially on some sort of password screen.
Do I think people type in differents ways enough to be able to tell who it is with an acceptable level of accuracy? Personally, I doubt it…
