Browser Plugin Randomizes the Rate of Your Keyed Input

If you’re really, really worried about privacy online, you can get a browser plugin that randomizes the way your keyed input appears to Web sites.

“Security researchers have refined a long-theoretical profiling technique into a highly practical attack that poses a threat to Tor users and anyone else who wants to shield their identity online. The technique collects user keystrokes as an individual enters usernames, passwords, and other data into a website. After a training session that typically takes less than 10 minutes, the website—or any other site connected to the website—can then determine with a high degree of certainty when the same individual is conducting subsequent online sessions…. The prospect of widely available databases that identify users based on subtle differences in their typing was unsettling enough to researchers Per Thorsheim and Paul Moore that they have created a Chrome browser plugin that’s designed to blunt the threat. The plugin caches the input keystrokes and after a brief delay relays them to the website in at a pseudo-random rate.”
