Odds are you will be monitored today � many times over.

Surveillance cameras at airports, subways, banks and other public venues are not the only devices tracking you. Inexpensive, ever-watchful digital sensors are now ubiquitous.

They are in laptop webcams, video-game motion sensors, smartphone cameras, utility meters, passports and employee ID cards. Step out your front door and you could be captured in a high-resolution photograph taken from the air or street by Google or Microsoft, as they update their respective mapping services. Drive down a city thoroughfare, cross a toll bridge, or park at certain shopping malls and your license plate will be recorded and time-stamped.
