Zuckerberg: Facebook Doesn't Use Your Mic For Ad Targeting (engadget.com)

During today's joint hearing before the Senate Judiciary and Commerce Committees, CEO Mark Zuckerberg fully denied the idea that Facebook listens in on your conversations via microphones to display relevant ads. Engadget reports: Senator Gary Peters (D-MI) asked him to answer "yes or no" whether Facebook used audio from personal devices to fill out its ad data, and Zuckerberg said no. The CEO explained that users can upload videos with audio in them, but not the kind of background spying that you've probably heard people talk about. Peters: "I have heard constituents say Facebook is mining audio from their mobile devices for the purpose of ad targeting. This speaks to the lack of trust we are seeing. I understand there are technical and logistical issues for that to happen. For the record, I hear it all the time, does Facebook use audio obtained from mobile devices to enrich personal information about its users?"

Zuckerberg: "We do not. Senator, Let me be clear on this. You are talking about the conspiracy theory passed around that we listen to what is going on on your microphone and use that. We do not do that. We do allow people to take videos on their device and share those. Videos also have audio. We do, while you are taking a video, record that and use that to make the service better by making sure that you have audio. That is pretty clear."

      As soon as lawyers are involved it becomes hard to avoid weaseling. I see two places. I understand his statement as "we won't record behind your back but as soon as you record anything or share it, it's ours to scavenge." This may already lead to surprising end user scenarios. The other weaseling is in 'better service'.
      I imagine that at some level of implementation they do voice to text conversion and feed that in to the text processing algorithms. The voice to text doesn't have to be perfect for that and it's a standard feature in youtube by now . More data could be mined if they see potential use for it, even if this potential use comes in the form of 'there are always idiots who think more data means more value'. The NSA has for a very long time logged voice patterns which they can match fairly well with recordings to identify people automatically. To use a simple example, any recording of Bin Laden would have said anywhere would have been detected automatically. I assume it exists at least in an experimental stage on the market as well.

      I don't notice it, then again I never bothered using the app or most of Facebook's "features"

      I don't understand the outrage, I thought everyone knew everything they did on facebook was mined and didn't care. Now, there's this swarm of sudden outrage because, surprise, their information was used in a way they didn't like.

      We're not at a situation in society where Facebook is a necessity. Internet arguably is, so complaining about ISP terms/abuses is quite valid, but complaining about some silly service that isn't adding much, if any value, is mass stupidity. Stop using the service, it's that simple.

      The issue is an inactive locked phone in the room where the discussion happens about a topic, will cause Facebook to show ads on that topic a few minutes later.

      I have only seen it happen with an Android phone, however the phone (not mine) was sitting on the couch when the conversation happened, and a few minutes later on a desktop computer (with a different Facebook account) got the ads. On the same wi-fi connection.

      The phone was not "recording for facebook" at the time, but the FB app may have been open. It did have the "OK Google" voice activated stuff, but again it was locked, and not being addressed at the time.

      The fact that _someone_ is doing _something_ like that is not up for dispute, I have seen it happen several times just like what thousands of other people have reported.

      Simply "using facebook" or "audio in video" is not what is happening so you are misunderstanding what people are saying is happening... or you are whitewashing it.

      That gaming of the system does seem to work on Android at least some of the time (it's definitely not guaranteed that it will - I'd guess my success rate is 50:50), but there are a lot of variables so the testing methodology would need to be pretty good to pin down exactly who is going what. Google is almost certainly listening as well - even if only for the "OK Google" keyphrase - so you'd need to do a series of tests with various permutations of apps and services with microphone access enabled/disabled, then monitor which ad networks and data brokers are actually serving the ads related to whatever you talked about to try and game the system. Don't forget that there is a massive web of resellers at work here too, so it might not be at all obvious that a given ad served from a third-party server was targetted based on Google's data, Facebook's data, or some other source entirely.

Government actors have been caught out time and time again lying to congress without consequence. If Facebook is indeed doing this, Zuckerburg would have some kind of protection in this circumstance.

    Zuck totally owned most of the Senators. Was not expecting that.

    Number of lazy, repeat and "I'm a total dumb fuck" questions by people who could not be bothered to research issues in advance dominated the hearing.

    Most amazing question was from Ted Cruz about the Palmer Lucky firing. It made the whole thing worth listening to. Had to rewind and play it back I was laughing so hard.

    With runners up incompetently hitting on the cross site tracking dimensions and lost opportunities to expose Zucks phony ignorance on the subject. Someone I don't remember who did kind of get him to admit it but in an overly generous way.

    On Microphone targeting the obvious follow up questions about data provided by third parties were never broached.

    It never occurred to anyone to ask about end users ability to control and view data obtained by Facebook from third parties that work quite a bit differently from Zucks claims about "their data".

    Zero questions on shadow profiles and tracking of people who don't even use the service.

    No pushback on magical "AI" claims vs. thinking human adversaries. Apparently Zuck thinks AGI is 5 years out or he's full of shit. Either way he's full of shit.

    Surprisingly there were people concerned with censorship aspects of the "hate speech" banning and calling out of cowards who think the first amendment is dangerous.

    Was also impressed with TIA mention (How Zuck could never have heard of TIA strains any and all credibility) This business of government asking for social media handles for Visa applications and government asking for data was nice to get on record. However the obvious "third party doctrine" related issues were predictable never followed up on.

    In all the Senate gets a D+ for dressing themselves and showing up.

      There are people in this topic that **insist** this has happened to them. I think that, in each and every one of those cases, those persons (or their known close relations) fed just enough data to facebook so that it can occasionally get a really good target.

      Has your significant other ever called you out over subtly reacting to something emotionally, and you thought you had a perfect poker face? Your partner knows you so well that they can read you... sometimes before you realize how you're actually feeling.

      The truth is, Facebook has so much data on you, they can predict what ads to target to you. It seems like magic, so people blame secret recording. But, no, it's just that people have shoveled so much data into facebook that it can get targeted hits. Facebook -- a data aggregation and ad company -- is doing this, and somehow people are shocked that they get it eerily right sometimes?

      But that truth is too embarrassing. Embarrassing to the person who willingly gave away all that data for free, and embarrassing to facebook haters that facebook is actually really, REALLY good at its mission. So we end up getting conspiracy theories that they're listening all the time.
