One 32x32 frame every 3 minutes? And only if you put everything right up against the screen, how terrifying.

- donkeyd 3y agoYeah, technically it's a pretty cool concept, but 'privacy risk' is way ahead of the real world.
- BizarroLand 3y agoI am so sick of "sky is falling" journalism.
- kkfx 3y agoIt's not much that the point: did you notice your phone lighting up the screen when you move around it? That's not much an "image" capture threat (meaning you covered the phone cam and allow the other sensors in that example) but a "person presence" and "person activity" threat. Essentially with apparently innocent and cheap sensors you can determine what happen in a home, perhaps selling some smart bulb who can just tune the light and light on automatically when you enter a room then turn off after a short period of time. Apparently a simple and innocent comfort idea, but also a potential cheap remote spying device. We already know some "strange" attacks like discovering keys pressed on a mechanical keyboard via the produced ambient noise, any of such potential threat alone seems innocent and low risk, but put together allow for a potentially cheap mass surveillance inside homes walls in a far less monitored ways.

- ben_w 3y agoAnd laser microphones. There's a whole range of technologies out there that people mock as unrealistic when they appear in SciFi, but turns out we can make.
- iwishiknewlisp 3y agoIts interesting, I remember reading about this is old tech from 2014, but it was about how its possible to extract speech from vibrations picked up by video. https://news.mit.edu/2014/algorithm-recovers-speech-from-vibrations-0804 https://news.mit.edu/2014/algorithm-recovers-speech-from-vib... I also found a discussion on hackerenews while looking it up just now: https://news.ycombinator.com/item?id=32466870 https://news.ycombinator.com/item?id=32466870
- onetimeuse92304 3y agoI would like to add to it that we do not know how various seemingly insignificant signals can be correlated together to reach some more significant conclusions. I always remind myself there exist people much smarter, much more motivated and with much more time on their hand who think about these things and figure stuff out. To deal with the problem (of security) seriously, the only possible sane policy is to not provide ANY unnecessary information under any circumstances. And that might not be enough, because the information that is legitimately needed to get the things we want might already be way too much.
- sandworm101 3y agoYup, its up there with the hack that turned turn hard drives into microphones: it sounds super scary until you see the practical limitations in action. They need access to your screen before even attempting to, slowly, build up a picture of your hand hovering over the phone. Its like watching them screem at the hard drives in order to get a faint peep out of the microphone.
- pona-a 3y agoI guess it's still rather interesting research, certainly within the "hacker spirit". It's just sad most have to resort to clickbait to get any any funding for such pursuits...
