Facebook Patent Imagines Triggering Your Phone's Mic When a Hidden Signal Plays on TV (gizmodo.com) 169

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.

      Oh, really? They are already doing it?

      Can you please explain to me how you can possibly 'trigger' your microphone only after when you detect an 'inaudible' signal from the TV? If they have a way to detect a signal before turning on the microphone, it's sure worth a patent!

      Of course, I'm just being facetious. It's probably the summary that is misguiding, as usual. In order to detect the signal, the microphone needs to be already on, i.e. the Facebook app has to already be listening to everything the phon

        You realize the Facebook app on an average phone has already been granted access to the phone's mic and could have it running constantly, listening for such an activation sound, right? So when it gets its wakeup call in bat-level frequency it starts recording and transmitting to the mothership.

    • This is pretty much how all broadcast TV is tracked. Neilson gives families trackers that listen for signals and then collects them. These psychoacoustic encodings are broadcast every 2.5 seconds. Facebook seems to have patented using a smartphone to do this rather than a dedicated device.

        The average person has a threshold that they have to be pushed beyond before they'll actually take anything like this seriously. What makes matters worse is that the average person has been so thoroughly indoctrinated by Corporate America and so-called 'social media' sites that sharing everything is what's normal and natural, and that people who want 'privacy' either have something wrong with their brains, or they're criminals with something to hide. With any luck this will all eventually catch up with everyone and there'll be a revolt. Until then all you can do is stay on-message, be consistent, and do what you can to protect yourself (i.e. don't use 'social media', so you're not part of the problem).

      I'm not even sure how this patent is supposed to work. How does your phone know to trigger the microphone unless the microphone is already triggered? Is this inaccurate reporting and the patent is really about sending the stream that is already being recorded by Facebook?

    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.

    Amazon eventually has something similar planned for Alexa, where casually spoken words (not directed at Alexa) will do exactly the same thing. The trend here is that any device in your vicinity (not even your own home, anywhere at all) can be triggered by any kind of sound (voice or ads, audible or not) to turn on your phone and record other conversation, or maybe to direct your phone web client to an online ad or retailer.

    We're screwed.

    But if it only turns on the microphone when it "hears" the sound, how does it hear it?

    Of course the microphone is turned on all the time, just that when it hears the sound it starts recording and send it home.

    Still a horrible idea and whoever conceived it should lose their basic human rights as a punishment since they want to take some of them (privacy) away from others. There is a special place in hell for people like these.

    Remember the story here [slashdot.org] just two weeks ago?

    The La Liga app, [gizmodo.com] which is the official streaming app for Spain’s most popular football league, has reportedly been using the microphones on fans’ phones to root out unauthorized broadcasts of matches in public venues like bars and restaurants.

    Sounds like the same thing.

This was picked up by small recording devices that people ("panelists") wore on their belt [wikipedia.org].

At night the user would connect the device to a base where it would recharge and send the information to the main office. Later devices used cell ph

    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.

    • by AmiMoJo ( 196126 )

      You can get cases with a cover for the camera, or stick-on privacy sliders designed for laptops but which fit phones okay. Add a bit of acoustic blocking foam to cover the microphone when closed.

      Another option to block the microphone is a dummy one in the headphone socket for phones that support headsets that way. Bluetooth and USB also work. Or you can go the other way and physically disconnect the mic on the phone, then connect an external one when you need it.

      Or rather the OS denies access to everything by default and you have to approve use when they app tries to use it. I mean all sensors, camera, GPS, microphone, accelerator/gyro, so on and so forth.

      I beleive Android does this already, not that it stops people from somnambulently clicking "allow", but it at least gives those of us who care a chance.

      Also default deny of sensor access when the application isn't open and active. A messenger application does not need to listen when I'm not using it.

When a hypothetical user is watching this ad, the audio fingerprint could trigger their smartphone or another device to turn on its microphone"

    How can it "turn the microphone on" if it was already "on" and constantly listening for this audible signal? Thus, the mic was already "on" and analyzing everything, all the time. This is aside from the asinine premise of this whole concept. I am sure we all have a BURNING need for our phones to be listening all the time, burning up the battery, doing god-knows-what in the background, sending personal info to places like Facebook, all so we can watch COMMERCIALS and then get even more automatic COMMERCIALS on our phones and give companies even more metrics about our personal lives, whereabouts, believes, and associations. Oh, man, sign me up now! I will make sure to throw away my DVR in the process, too, so I can watch COMMERCIALS religiously...

    What I want are HARDWARE switches for: microphone, cameras, and radios on my devices. Funny how many devices USED to have such things in the past.

  • This has already been done. Audio beacons. Those tracking companies hate microphone permissions on iOS (and possibly android now) for this reason.

    As I've said before [slashdot.org], I believe the best strategy for fighting this type of privacy invasion is to simply pollute their incoming data. Figure out which triggers they're using to initiate the recording (e.g. inaudible audio signal at the beginning of a commercial), and duplicate it and program your phone and other speakers to play them back anywhere and everywhere. The mall, the park, stadiums, restaurants, concerts, movie theaters, amusement parks, traffic jams (over your car stereo with your windows rolled down), YouTube videos, etc.

    There's an apocryphal story that at the end of the Cold War, members of the KGB and CIA got together for beer and to swap war stories. The CIA spooks lamented how hard their job had been. They had to struggle just to get anyone into the country since the Soviet Union was such a closed society, while the KGB could simply enter on a tourist visa and drive up to (and even take a tour of) most targets in the U.S. The KGB spooks disagreed, saying that theirs had been the harder job. The U.S. produced so much information that they had to devote huge resources to sift through it all to figure out which was credible and which was not. e.g. If the National Enquirer published a story about the USAF testing a captured UFO at Area 51, they had to figure out if it was made-up or if there was really something to it.

    • Indeed, but here is the bit I didn't initially get... if it starts recording when it hears an audio signal from a TV or the like then surely what it records will mostly be the audio from said TV. If the trigger is at the start of an advert and then starts recording then they would the record the audio of the ad... something they already know. If they collect say 10 seconds of audio from before the trigger event and run for ad-length-plus- 20 seconds they get to hear the content that precedes and follows.
