Rysiek,

   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:
     [3]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).
