I've tried this [0] "typing biometrics authentication" out in some test apps. It worked well in detecting typing a password between two hands, just my left hand and just my right hand. I tried to do the same cadence - but it seems to also notice keypress duration as well. Not sure how I feel about my typing rhythm being a personal signature.
Search-as-you-type interfaces, including search engines, often have enough signal to perform keystroke timing for the same purpose.
