Let's talk about your smart phone for a minute. Admit it: you love it. You depend on it. It keeps you in touch with your family and friends — wherever they are and wherever you are. You use it to browse the web, to shop and to find your way across town. It's a modern marvel.

It's a also a device of mass surveillance. Every time you slip that phone into your pocket, you're making a deal with the carrier: you get to use it, but the company gets your data. All of your data: where you are, where you travel, where you shop, who you're with, where you sleep — even who you sleep with.

Our next guest says we are living in the golden age of surveillance. Not just because of your phone; but because of your computer, the cloud — and a government security apparatus and big business that mine, track and sell your data without your consent.

Bruce Schneir says all this threatens our privacy and freedom — and it's time to wake up and do something about it.

Guest

Bruce Schneier, security technologist and fellow at Harvard University's Berkman Center For internet And Society. He's the author of the new book, "Data and Goliath: The Hidden Battles to Capture Your Data and Control Your World."
