Cops Increasingly Trawl Through Driver's License Photos

Facial recognition software comes of age, and creepiness

|

The faces of more than 120 million people are in searchable photo databases that state officials assembled to prevent driver's-license fraud but that increasingly are used by police to identify suspects, accomplices and even innocent bystanders in a wide range of criminal investigations.

The facial databases have grown rapidly in recent years and generally operate with few legal safeguards beyond the requirement that searches are conducted for "law enforcement purposes." Amid rising concern about the National Security Agency's high-tech surveillance aimed at foreigners, it is these state-level facial-recognition programs that more typically involve American citizens.
