A facial recognition system being used by the US's Division of Motor Vehicle (DMV) has identified three people who were attempting to apply for multiple licences.Following cooperation between New York and New Jersey police, three men were found to be using phony aliases, birthdays and Social Security numbers to get multiple licenses, the Daily News learned.”Facial recognition has greatly enhanced our investigators' ability to deter identity theft and identify subjects committing fraud,” DMV Division of Field Investigations Director Owen McShane said.More than 30 states use facial recognition technology to take driver license photos at their DMV bureaus – the technology was initially deployed in 2009.The technology carefully examines various facial features to compare a new license photo with others that have already been taken. If a new photo appears to be nearly identical to a previous photo, the software is triggered that someone could be attempting to take on another driver's identity.
