So I guess I'm just very worried that with Internet privacy, we're doing the same thing we're doing with medical records, is we're throwing out the baby with the bathwater, and we're not really thinking about the tremendous good that can come from people sharing information with the right people in the right ways.

You carry a phone. It knows where you are. There's so much more information about you, and that's an important thing, and it makes sense why people are asking difficult questions.

I think the main thing that we need to do is just provide people choice, show them what data's being collected -- search history, location data. We're excited about incognito mode in Chrome, and doing that in more ways, just giving people more choice and more awareness of what's going on.

For me, privacy and security are really important. We think about it in terms of both: You can't have privacy without security.

Oh, I think there are a lot of people who would be buying and selling online today that go up there and they get the information, but then when it comes time to type in their credit card they think twice because they're not sure about how that might get out and what that might mean for them.

Historically, privacy was almost implicit, because it was hard to find and gather information. But in the digital world, whether it's digital cameras or satellites or just what you click on, we need to have more explicit rules - not just for governments but for private companies.
