No Smiling in Driver's License Photographs
In other biometric news, four states have banned smiling in driver's license photographs.
The serious poses are urged by DMVs that have installed high-tech software that compares a new license photo with others that have already been shot. When a new photo seems to match an existing one, the software sends alarms that someone may be trying to assume another driver's identity.
But there's a wrinkle in the technology: a person's grin. Face-recognition software can fail to match two photos of the same person if facial expressions differ in each photo, says Carnegie Mellon University robotics professor Takeo Kanade.
