Some Real Spooky Stuff From MIT

Your potato chips have a security flaw.

Researchers at MIT, Microsoft, and Adobe have developed an algorithm that can reconstruct an audio signal by analyzing minute vibrations of objects depicted in video.

Read that. Ponder the implications.

Then watch this:

Just saw this earlier. Pretty crazy stuff!

A friend of mine, who at the time worked for Hughes Aircraft in Goleta, related a visit by the NSA (this occurred in the early 1980's) and they showed him what he had been working on via screen captures from his CRT that were taken from an aircraft 3,000 feet over the building.

The tech people have been on top of this for quite a while. Who knows what they are working on now...

It's not spooky, or new - even. I've heard theories on this dating back to 7th grade math class. They're just now realizing a way to extract it perhaps, albeit, it's not really spooky at all in that most video recordings already record for sound & also there's not many scenarios in which you're "ok" you're being recorded on video, but want what you're SAYING completely private.

It is not new. You are thinking of sound being recorded from things like vibrating glass windows and such.

The sound in this case is not being recovered from the sound recording on the video. It is being recovered from the video itself. The vibration of a bag of potato chips caused by the sound in the room. The video of the bag's vibrations are translated into sound. You missed the significance of the soundproof glass.

That is totally new.

Yes. In the military we spent a lot of money on TEMPEST.

If someone has developed a new technology that adds another tool to the government's ability to invade our privacy, that is spooky. Damned straight.
