Carissa Véliz discusses her new book 'Privacy is Power', focusing on the importance of understanding how our data is used and how we can protect our privacy. Have you ever been denied insurance, a loan, or a job? Have you had your credit card number stolen? Do you have to wait too long when you call customer service? You might have the data economy to thank for all that and more. Digital technology is stealing our personal data and with it our power to make free choices. To reclaim that power, and our democracy, we must take back control of our personal data. Surveillance is undermining equality. We are being treated differently on the basis of our data. But what can we do? Join the author of Privacy is Power: Why and How You Should Take Back Control of Your Data, Carissa Véliz and Professor Rasmus Nielsen, Lead Researcher on the Oxford Martin Programme on Misinformation, Science and Media, as they discuss the need to understand the power of data better, how we can start protecting our privacy and how we need regulation. It is time to pull the plug on the surveillance economy.
