Rysiek,

https://en.wikipedia.org/wiki/Keystroke_dynamics

We may first want to understand the minimum resolution that timing requires. Keypress events can be randomized within this interval.

Another track:

170WPM ~= 42000 KPH ~= 11 KPS

So, maybe we have 90ms delay on average between keystrokes for a speed typist.

I didn't realize you could use keystroke analysis to identify one person out of a pool of millions, rather, that a certain keystroke pattern matches as best a certain subset of users but it wouldn't be valuable/practical for positive identification. Text analysis is probably a way more useful signal.

In for more details,

Hi all,

so, as we all know, Big Brothers tend to use keypress timings to identify
users on the Net. This of course leads to a question: are there ways to
introduce randomness in keypress timings?

I imagine a Linux kernel module that could be doing this, for instance.
Anybody heard of anything like this?

There are things like All is Text:
https://addons.mozilla.org/pl/firefox/addon/its-all-text/

But this is not really a solution, rather a work-around (for instance it does
not solve the problem for multiple browsers).
