Raleigh, N.C. ? In its search for fugitives, the FBI has begun using facial-recognition technology on millions of motorists, comparing driver’s license photos with pictures of convicts in a high-tech analysis of chin widths and nose sizes.

The project in North Carolina has already helped nab at least one suspect. Agents are eager to look for more criminals and possibly to expand the effort nationwide. But privacy advocates worry that the method allows authorities to track people who have done nothing wrong.

“Everybody’s participating, essentially, in a virtual lineup by getting a driver’s license,” said Christopher Calabrese, an attorney who focuses on privacy issues at the American Civil Liberties Union.

Successful search

Earlier this year, investigators learned that a double-homicide suspect named Rodolfo Corrales had moved to North Carolina. The FBI took a 1991 booking photo from California and compared it with 30 million photos stored by the motor vehicle agency in Raleigh.

In seconds, the search returned dozens of drivers who resembled Corrales, and an FBI analyst reviewed a gallery of images before zeroing in on a man who called himself Jose Solis.

A week later, after corroborating Corrales’ identity, agents arrested him in High Point, southwest of Greensboro, where they believe he had built a new life under the assumed name. Corrales is scheduled for a preliminary hearing in Los Angeles later this month.

Facial-recognition software is not entirely new, but the North Carolina project is the first major step for the FBI as it considers expanding use of the technology to find fugitives nationwide.

So-called biometric information that is unique to each person also includes fingerprints and DNA. More distant possibilities include iris patterns in the eye, voices, scent and even a person’s gait.

Establishing standards

FBI officials have organized a panel of authorities to study how best to increase use of the software. It will take at least a year to establish standards for license photos, and there’s no timetable to roll out the program nationally.

Calabrese said Americans should be concerned about how their driver’s licenses are being used.

Licenses “started as a permission to drive,” he said. “Now you need them to open a bank account. You need them to be identified everywhere. And suddenly they’re becoming the de facto law enforcement database.”

State and federal laws allow driver’s license agencies to release records for law enforcement, and local agencies have access to North Carolina’s database, too. But the FBI is not authorized to collect and store the photos. That means the facial-recognition analysis must be done at the North Carolina Division of Motor Vehicles.

“Unless the person’s a criminal, we would not have a need to have that information in the system,” said Kim Del Greco, who oversees the FBI’s biometrics division. “I think that would be a privacy concern. We’re staying away from that.”

Dan Roberts, assistant director of the FBI’s Criminal Justice Information Services Division, added: “We’re not interested in housing a bunch of photos of people who have done absolutely nothing wrong.”
