Driver's Licenses with Digital Watermarks

ForceQuit writes "MIT Technology Review reports that Minnesota will begin issuing a unique driver's license designed to combat counterfeiting. It includes a reflective image (of a loon) that appears to float above and below the card when the license is tilted. It also includes an invisible, digital watermark capable of carrying security data such as date of birth. The information would be readable only through a computerized scanner, which law enforcement officers could carry."
