Keyboard Privacy

Prevents behavioral profiling by randomizing the rate at which characters reach the DOM.

What is Keyboard Privacy?

The 'Keyboard Privacy' extension for Chrome is an innovative tool designed to hinder attempts at behavioral profiling. It accomplishes this through randomizing the speed at which characters are acknowledged in the Document Object Model (DOM). This method effectively conceals your unique typing rhythm, a metric that can potentially be exploited by cyber threats for identification. This plugin is a result of research led by security experts Paul Moore and Per Thorsheim. Its up-to-date version adjusts to various input types, reflecting significant advances in the industry.

This seems to work @ 300ms on Keytrack but they were able to get high confidence @ 200ms for me. The Experimental port on Mozilla Addons does not work at all for me however, any chance you can finally port this to Firefox, now that they have a decent WebExtension API?

It's great stuff, super interesting.

No, as of 2017 Nov, all the "biometric" can over come this tiny trick with over 90% confidence. Even 1000 dwell/delay would not help at all.
