So they generated training data from one laptop and microphone then generated test data with the exact same laptop and microphone in the same setup, possibly one person pressing the keys too. For the Zoom model they trained a new model with data gathered from Zoom. They call it a practical side channel attack but they didnt do anything to see if this approach could generalize at all

>>lispis+Pq
I believe that is the generalisable version of the attack. You're not looking to learn the sound of arbitrary keyboards with this attack, rather you're looking to learn the sound of specific targets.

For example, a Twitch streamer enters responses into their stream-chat with a live mic. Later, the streamer enters their Twitch password. Someone employing this technique could reasonably be able to learn the audio from the first scenario, and apply the findings in the second scenario.

Finally, a real security weakness to cite when making fun of people for their mechanical keyboard. Time to start recording the audio of Zoom calls with some particularly loud typers...

>>TechBr+CL
Mechanical keyboard user here. Most of us use mechanical keyboards because they're a lot more fun to type on. That's it. Because if you're not having fun, what's the point?

>>tharne+oj1
I don't know, typing?

Else, something like Mai Tais on the beach sounds more fun, maybe it's just me...

>>coldte+nv1
but mai tais on beach don't get you money, and if you are going to type on something, its better to make sure its comfortable for you.

>>whatis+Bz1
But inconfortable for others. Surely you all know it bothers a good amount at least some of your colleagues, right?

Quiet switches for the office, clicky switches for home. Not exactly a hard problem to solve :)
