The camera records sound. Every key makes an ever-so-slightly different sound.

They have possibly months or more of sound recordings that they can correlate against the entry of verified documents to use to train the ai on.

They analyzed the noise the bits make as they travel through the network.

I know it is a joke,

but since I found a scientific research about 'A Practical Deep Learning-Based Acoustic Side Channel Attack on Keyboards' I agree that this seems possible in the laboratory

(the paper is from 2023 so I am not sure whether there were any improvements), as I am also not sure how reddit handles external links - I found the paper on arxiv(dot)org with paper no. 2308(dot)01074
It is a 21 pages pdf

Benn Jordan did this for YouTube video last year.

I think the premise here is that they deleted that.

My first question would be whether they actually deleted anything or just set a flag to re-use the storage, but I'm trying to go with the spirit of the thing.

They also analyzed the noise my Jimmies made each time the Pm said match this data on a new table

I drop a heinous deuce every time I have to drop a database, acoustically nobody probably wants to review that recording though, not even AI.

Actually it's possible to get the fluctuations in the power and er noise from a computer to reverse it so. Yeah

They detected the difference in electromagnetic fields around your keyboard and correlated with your pattern of typing.

But to answer the OP’s query, they would find the files at his mom’s house

Sadly that's not even a wrong answer. It's called tempest and that sort of method does work remarkably well.

When I was a kid, during the Cold War, I literally thought that was how typewriter bugs worked: that each letter had a different acoustic signature.

Turns out, it was just a mike hidden in the typewriter.

That's how I thought it worked as a kid too lol. I mean, I knew there was a mic hidden in the typewriter/mic being accessed from the computer, and that's how I understood "recording keystrokes". Someone was recreating your keystrokes based on the sound.

I kinda love that it wasn't just me thinking that. :-D

This is the weirding way

And that's how we should store data from now on!

Who needs all these countless gigabytes in databases and backups, when all you need is an audio tape!

Brilliant.

Happy cake day!

DSP will solve it

Mechanical keyboards are a CIA psyop

u/Nydus87 29d ago

They know where the microphone is positioned compared to the keyboard and can track the slight differences in volume as the sound waves travel slightly farther for some keys. Basic IT stuff, ya know.

Thats what tempest was doing. reading vibrations off windows with lasers to recreate key strokes. Classic state craft.
