For the past several weeks, public scrutiny of Facebook has snowballed in the aftermath of the Cambridge Analytica data controversy. This week, Facebook founder CEO Mark Zuckerberg testified before Congress on the social media platform and how it handles user data and privacy. On April 11th, the news program Chicago Tonight invited UChicago CS assistant professor Blase Ur to participate in a discussion of Zuckerberg's testimony and how Facebook and other websites track and use online activity.

Appearing alongside attorney Charles Mudd, Ur gave Zuckerberg a “B” for his testimony and criticized the questions of senators and representatives, who failed to push him on critical issues of transparency and consent. He also discussed how Facebook, Google and other advertising networks collect data from internet users, and the difference between a data “breach” and the improper use of data by Cambridge Analytica. And no, he's not deleting his Facebook account.

Watch the full segment at the Chicago Tonight website, and learn more about Ur's research on privacy and security with SUPERgroup.
