Boffins convert typing sounds into text with 95% accuracy (www.theregister.com)

Researchers in the UK claim to have translated the sound of laptop keystrokes into their corresponding letters with 95 percent accuracy in some cases.

That 95 percent figure was achieved with nothing but a nearby iPhone. Remote methods are just as dangerous: over Zoom, the accuracy of recorded keystrokes only dropped to 93 percent, while Skype calls were still 91.7 percent accurate.

In other words, this is a side channel attack with considerable accuracy, minimal technical requirements, and a ubiquitous data exfiltration point: Microphones, which are everywhere from our laptops, to our wrists, to the very rooms we work in.

I think I might have achieved security through obscurity. My custom keyboard is a unique shape and almost all the keys are one unit. Not only is it different enough from a traditional keyboard that the neural network probably won't understand it, the function layers I use obscure whether I'm typing a letter at all.

Good luck listening to mine

Does that come with free fingerless gloves?

Of course not. The fingerless gloves are also niche, boutique, and premium.
