Turns out on-call car service Uber compiles a lot of data about its customers. They can get a pretty good idea of what you are up to just by the way you use their service. Are you surprised? How much privacy is there in the age of the internet?

Marc Rotenberg is a lawyer specializing in privacy and civil rights. He is president of the Electronic Privacy Information Center, a public interest research group involved in privacy litigation and public policy. He also teaches about these issues at Georgetown University Law School in Washington D.C.

Rotenberg says he doesn't use the word fear when discussing civil liberties in the information age. It is disempowering, he feels. Rather, there are challenges to be met, problems to solve. Rotenberg sat down with Steve Scher in late November, 2014, to discuss those challenges.
