Facebook Patent Imagines Triggering Your Phone's Mic When a Hidden Signal Plays on TV (gizmodo.com)

Based on a recently published patent application, Facebook could one day use ads on television to further violate a user's privacy. From a report: The patent is titled "broadcast content view analysis based on ambient audio recording." It describes a system in which an "ambient audio fingerprint or signature" that's inaudible to the human ear could be embedded in broadcast content like a TV ad. When a hypothetical user is watching this ad, the audio fingerprint could trigger their smartphone or another device to turn on its microphone, begin recording audio and transmit data about it to Facebook.

What can really be done?
I explain shit like this to people, they call me paranoid.
I show them proof, they say they don't care.
Privacy? They say they have nothing to hide.
They're beyond saving, but they're the majority. They don't care about their privacy, all they know is they can trade it for more cute cat mobile games.
So what can you do?

Devices Need Transient Permissions

[Anonymous Coward]

I'd love a pop-up EVERY TIME an app on my iPhone needs permission to access this or that (with the option to okay it into perpetuity should I choose). And instead of simply "OK" to grant permission, offer me a list: OK for 5/10/30 minutes, 1/3/6/12 hour(s), 1/7/30/60/90 day(s), or forever. Perhaps even the option to okay permissions for the app "for X minutes OR until the app is no longer active or is sent to the background, whichever is soonest."

Then I could be SURE that granting that one app that needed to read a QR code so got camera access doesn't FOREVER have camera access. This would fix issues with Facebook wanting to access my camera, mic, phone contact list, photo library, etc. when I'm not expecting it.

Another awesome option would be to grant FAKE permission. I.e., an app asks for my phone contacts and won't let me continue unless I grant it FULL access, I can click "OK--grant access to empty phone contacts" or "fake mic that only records white noise" or "fake camera that only records black as if obscured/covered by a phone case".

Yes, apps could detect permissions. Request access to motion/gyro sensors, grant access to fake, and suddenly movement detected is zero... that would be suspicious. Even so, I'd love that option.

And finally, I don't want apps to be able to query and discover if permissions are temporary or permanent. They just have permmissions--for now--that's all they can know.

Manually disable camera and microphone

[myid]

Phones and computers need a manual (not software) "data capture" on/off switch. This switch would physically disable the phone's microphone and cameras (and if possible, screen capture).

If I manually slide the data capture switch to OFF, then the mic and cameras are physically disabled. No matter what any data, software, or user preferences are, the mic and cameras are physically unable to capture sound or images. They can't capture sound or images again, until I manually slide the data capture switch back to ON.

The average person has a threshold that they have to be pushed beyond before they'll actually take anything

This process has a taxonomy that comes under anal fist fucking, right now they're really enjoying it but they're looking at the fire extinguisher with some mixture of fear and anticipation.
