People share information about themselves every day by using store loyalty cards, internet search engines, social networking sites, and online coupons. Many people — like the character in this video — decide that the benefits of these services are worth sharing some personal information with businesses, ad networks, and others.

But what if you shared information simply by walking through your local mall with your phone? What if businesses used your phone’s Wi-Fi signal to track your movements through their stores? And what if they did it without your knowledge or okay? The FTC plans to raise those questions in a seminar on Mobile Device Tracking on February 19, 2014. It’s the first event of our Spring Privacy Series.
