So they can also exfiltrate audio and video
- kevin_thibedeau 3y agoThis is why Snowden removes the microphone from his phones.
- rolph 3y agome too, and i also remove the camera[s], and put a dab of urethane over the hole. if i know there is an accelerometer i cut Voltage, and shunt it to ground

- sizzle 3y agoWhat’s the privacy issue with accelerometer?
- Veliladon 3y agoBecause it can be used to roughly track location through 3D space. It's nowhere near as accurate as practically any other method but for "good enough" a lot of the time it'll do the job.
- codebje 3y agoOne I could think of is you could use accelerometer data to know if the phone is moving, and how: is it just being lifted and interacted with, is the user walking or running, are they in a car. For a high profile target you might also be able to track their approximate location if you know their starting point and their acceleration profile - speed up, slow down, turns, time taken. Enough, at least, to execute an ambush.
- AlotOfReading 3y agoWith enough data and a high SNR, you don't even need the starting point or the velocity profile. Just the turns and distances are enough in combination with a map to uniquely identify most journeys. The problem with applying that more globally is sensor drift.
- steve_adams_86 3y ago> Drawing from existing literature, we found that accelerometer data alone may be sufficient to obtain information about a device holder's location, activities, health condition, body features, gender, age, personality traits, and emotional state. Acceleration signals can even be used to uniquely identify a person based on biometric movement patterns and to reconstruct sequences of text entered into a device, including passwords. https://dl.acm.org/doi/10.1145/3309074.3309076 https://dl.acm.org/doi/10.1145/3309074.3309076
- cpv 3y agoThere was a research in 2011 about using the accelerometer to log your keystrokes https://www.extremetech.com/internet/92946-a-wiggly-approach-to-smartphone-keylogging https://www.extremetech.com/internet/92946-a-wiggly-approach...
- jlund-molfese 3y agoGood for you. There are so many examples of cameras on internet-connected devices being used to blackmail people, and criminals are pretty creative, so they'll keep thinking of other nefarious things to do in the future.
- dtgriscom 3y agoWait a minute: how does it function as a good ol' phone?
- kevin_thibedeau 3y agoHe attaches a USB microphone.
- IYasha 3y agoAlso, it doesn't have to be USB on devices with 3.5 4-pin jack.
