In the digital world, there is an enduring tension between privacy and security. What is our right to privacy from the government or the companies whose services we use? What rights does our government have to surveil us in the name of national security? 

Most of us have a general understanding of the basic tradeoff in the Internet era—you give up some data in exchange for free or freemium services like Gmail or social media apps like Instagram. But the data marketplace goes well beyond the Big Tech players we’re most familiar with, and the depth and breadth of these processes, and the players involved, are often much harder to pin down.

What role do data brokers play and what sorts of data do they have access to? Is our data simply for sale to the highest bidder? Can even the chips in car tires be used to spy on people?

Joining us to discuss all of this is Byron Tau, whose investigative work has shone a light on the connections between tech companies and government surveillance. His latest book, "Means of Control: How the Hidden Alliance of Tech and Government Is Creating a New American Surveillance State," uncovers the extensive ways our data are used to watch and influence us as the American public. Byron is also a reporter at NOTUS, a new publication covering politics and policy from the Albritton Journalism Institute, and an adjunct lecturer at Georgetown University.
