Cops will see if your face rings a bell

Facial recognition software could roll out to police in the U.S. as soon as this fall. A device that attaches to an iPhone can snap a picture, up to five feet away, and search a criminal database for a match.

From the WSJ:

Here's how it works: To scan a person's iris, police officers can hold the special iris-scanning camera on device, called MORIS, about 5 to 6 inches away from an individual's irises. After snapping a high resolution photo, the MORIS system analyzes 235 unique features in each iris and uses an algorithm to match that person with their identity if they are in the database.
For the facial recognition, an officer takes a photo of a person at a distance of about 2 feet to 5 feet. Based on technologies from Animetrics Inc., the system analyzes about 130 distinguishing points on the face, such as the distance between a person's eye and nose. It then scans the database for likely matches.

Civil liberties advocates are up in arms.
