If websites are able to track their users’ typing behavior and mouse movements, then the websites may be able to use that data to fingerprint, track, and possibly identify their users. Is this a real privacy risk? If so, what are the methods to counter keyboard and mouse fingerprinting by websites? Note that I do not want to disable JavaScript.
I used to have a piece of software that had a phantoms mouse. You move this phantom pointer to where you want the mouse to be, and middle click (or something, it’s been several years), and the real pointer would be moved there on a smooth line movement. It was used to allow an old piece of software to work with windows XP. Could be useful here.
For keyboard, just type in notepad++, then copy and paste into the text field.
