Cambridge Analytica whistleblower Christoper Wylie, appearing before a committee of British MPs on Tuesday, said that Facebook has the ability to spy on users in their homes and offices. …
“On a comment about using audio and processing audio, you can use it for, my understanding generally of how companies use it… not just Facebook, but generally other apps that pull audio, is for environmental context,” Wylie said. “So if, for example, you have a television playing versus if you’re in a busy place with a lot of people talking versus a work environment.” He clarified, “It’s not to say they’re listening to what you’re saying. It’s not natural language processing. That would be hard to scale. But to understand the environmental context of where you are to improve the contextual value of the ad itself” is possible.
Wylie continued: “There’s audio that could be useful just in terms of are you in an office environment, are you outside, are you watching TV?”
Facebook has long denied allegations that its app listens in on users in order to customize ads.
