Invited to testify before the U.S. Senate, the CEO of Facebook, Mark Zuckerberg, replied to many questions asked by U.S. Senators regarding the way Facebook gets and uses information about users.
Some of the topics Mark Zuckerberg had to talk about were also rumors that Facebook is allegedly using the microphones equipped in devices ( computers, laptops, mobile phones, tablets ) to listen to the private conversations of users, and then serve up ads related to specific trigger words spoken.
Mark Zuckerberg categorically denied this rumor.
Things are however a bit different regarding the videos users post on Facebook. According to Mark Zuckerberg, Facebook does some checks to the sound of the videos with the purpose of improving the quality of the services provided by Facebook.
Zuckerberg also had to address the rumor that Facebook might be “tapping into” the private text chats between users with the purpose of serving personalized ads. Mark Zuckerberg deviated a bit from the topic by providing a reply related to WhatsApp and the way telecommunication encryption technology makes it impossible to intercept text messages.
