Sizing your digital footprintIn September 2011, a new CBS drama called "Person of Interest" debuts. It explores the idea of using high-tech data to solve crimes. In reality, we all leave digital evidence, or clues, whether we know it or not. CNET's Kara Tsuboi reports.
-From the time you wake up to the time you finish your day, you've let an electronic trail of decisions and activities. It's called your digital footprint. -Digital footprint is all the record daily when you use phones, when you use computers, where you go, and what you're doing. - Peter Eckersley works for the electronic frontier foundation, a digital civil liberties organization based in San Francisco. He says the average person can have hundreds if not thousands of digital encounters a day, all adding up to one gigantic public record. -One place you will definitely leave your digital footprint is on city streets. Look around, cameras are watching your every move. -Watching us for 10,000 eyes. -Listening with a million ears. -Eckersley says, there are positives and negatives to this enormous digital footprint we're leaving behind. -It lets us such through our own records. It let's us learn things about us also. The downside is it also may let people we don't like learn these things about us. -Controlling or minimizing your digital footprint can be a daunting if not impossible task, but Eckersley recommends starting with secure browsing through https. -That means the connection is encrypted and people who are watching your network can't see what documents you're asking for, what searches you're doing, what pages you're reading. -Also make sure your cellphone is password protected and you've customized your location settings so you can't be tracked unknowingly, baby steps in reducing your digital footprint.
