Due to the discussion around #deepseek and the #privacy aspects of using it I read about #KeystrokeDynamics.
Imagine - each time you fill a form on the some website you're actually leaving fingerprints on it by the way you type. If the site reads your keyboard through a websocket connection and thereby knows the rhythm you have clicking your single keys, the time you hold down each key and the pauses you make thinking, this is a biometric that might even reveal the mood you're in.
There's tons of literature out there about various aspects of using keystroke dynamics.
I'm using a #deskhop* to connect my keyboard and mouse to my notebook and #Librem5 mobile phone to use both seamless like a multi-monitor setup.
Reading about a failed indiegogo campaign to build a usb device changing the metrics of typing in a way to cloak keystroke dynamics I had the idea that this maybe could be an extension to deskhops functionality.
