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.

Re:There's only two reasons you'd patent this:

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?

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.
