I recently came across an example of an online security method I’d never seen before.
The website (for an online course) asks that the user submits a typing test every time they submit an assignment to prevent cheating.
I didn’t know this, but apparently, we all have a different type pattern, and by looking at the way, we type, the system can tell if it’s you typing or someone else.
In terms of practical application, I can’t see it replacing passwords anytime soon, but it could form part of a 2-3 part authentication (we wouldn’t want to make it too hard for the user to access their account).
