The Guardian has posted a video demonstrating how a social media tracking company can create a complex and eerie picture of your life using  just a few mobile apps: Foursquare, Facebook and Twitter.

Are you concerned about how much your phone reveals about you? The Privacy Rights Clearinghouse has more information about privacy and smartphone settings.

Here’s more from the Guardian: “These images sometimes contain latitude and longitude details – automatically embedded by smartphones within so-called ‘exif header data’. Riot pulls out this information, analysing not only the photographs posted by individuals, but also the location where these images were taken.” (Via Gizmodo)
