This is an article about KPA (Key-Pattern Analysis). The idea is to analyse and look for patterns in keystrokes, and use this information to authenticate users, in addition to passwords, I guess.
The article covers research work done by a small group of Lebanese at AUB. This is somehow sensational reporting, with the title "Soon, hacking to be made ineffective!", but it contains some info and I thought I'd share it here.
I vaguely remember this idea having been studied before, so I don't know why it's presented here as a revolutionary novelty, but it's one thing worth exploring, I'm sure.
