Zuckerberg: Facebook Doesn't Use Your Mic For Ad Targeting (engadget.com) 257

Posted by BeauHD from the uneasy-feelings dept.
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."

      Sounds like he's making the point that when the user records a video, audio is likely included with the video, the audio is in fact recorded in that situation and submitted to facebook, and facebook might use the audio from that user submitted recording for quality control purposes. Quality control purposes may or may not include targeting more reasonable advertising.

        Zuck's outfit is certainly not alone in this, but the fact The Facebook has the ability to listen when they deem it appropriate is troublesome enough. At this point, we basically have to trust an information-gathering juggernaut not to use this ability to ever gather information about us.

        As others have wisely pointed out, listening all the time to everyone is not technologically feasible, yet the threat of a targeted listening campaign looms very possible and extremely likely to occur.

        The "OK google" and similar trigger phrases are processed by a special low power DSP. The main phone OS does not constantly listen, only the DSP does and the DSP does not contain any recording capability. It's designed for low power, always on operation.

        To record constantly would consume too much power, and would also need to either transmit a lot of data or do power-hungry processing. Voice assistants don't do speech recognition on the device, they use a cloud service because it is more accurate and can br

      • Depends on how they implemented it. If they were streaming your mic to a server, that would be trivial to detect. It would also drain your battery and use a ton of bandwidth. If they just listen locally, pick out keywords, and then piggyback a small amount of meta-data onto an existing server round-trip, you may never find it. This type of audio processing, though, may use significant CPU cycles which would give a clue but you would still have a heck of a time deciding if that was audio processing or ju

    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.
