lip, the circumference of one's irises, and the distance between the pupils,

- VIRGINIA BEACH - New software that can analyze a face
may transform the sometimes imprecise art of identifying criminals - comparing
mug shots to people on the street - into a science, police say.

software to help officers snare criminals and find runaways, police said.
-
- The Beach has used closed-circuit TV cameras to watch
the Oceanfront from the 2nd Police Precinct since 1993, largely for checking
traffic and observing crowds.
-
- Under the new system, the 10 cameras would feed images
of people as they strolled along the Oceanfront to monitors, where the
software would sort faces against a database of mugshots, looking for a
match, said Capt. Gregory G. Mullen of the Special Investigations Department.
-
- Beach police said the database includes about 2,500 outstanding
felony warrants as well as pictures of runaways and missing people, he
said.
-
- The software generally works by creating a ''map'' of
the face and then identifying 80 distinctive points. To achieve a match,
14 of those points must align with a database picture, often a mugshot,
Mullen said.
-
- By comparison, fingerprints only require 11 points to
match the whorls and ridges that make up each person's unique print.
-
- Once the computer spits out a match, an officer at the
2nd precinct would radio an officer on the street for further action.
-
- ''A match will not give officers probable cause to arrest,''
Mullen said. ''Only enough to stop and question them.''
-
- In laboratory tests, under ideal lighting, the software
had a 99.3 percent accuracy rate. It is unknown what the accuracy rate
would be on the streets with varying weather and lighting conditions.
-
- ''It's no different than a policeman holding a mug shot
in his hand on the corner as people go by,'' said Police Chief A.M. Jacocks.
''In fact, it's more efficient.''
-
- It is not clear how the new technology will be accepted
by the courts once someone is arrested because of computer identification.
-
- Several vacationers at the Oceanfront said that while
public safety is a priority, they would be concerned about cases of mistaken
identity.
-
- ''There are plenty of people that look alike,'' said
Sterling Harris of Richmond, as he paused outside a shop on Atlantic Avenue
on Thursday. ''I hope they don't sit behind the cameras looking for people
to mess with.''
-
- Police insisted that the opposite is true. Allowing a
computer program to identify someone takes the human error out of the equation,
Mullen said.
-
- But Kent Willis, director of the Virginia American Civil
Liberties Union, worries about privacy implications and the Big Brother
overtones.<p. ''This is simply the newest in a long series of new technologies
that allow the government to invade our private space,'' said Willis.
-
- Photographing people as they lick ice cream on the Boardwalk
is similar to dusting park benches and other public surfaces for fingerprints,
he said. The motive may be admirable but the result is the same - government
invading people's privacy and collecting information on citizens.
-
- The police said they would toss out any pictures that
didn't match, but Willis called those promises slippery. Once the police
started using the technology, they might decide it would be helpful to
keep photos on file.
-
- ''There's a long history of government abusing information
it has gathered,'' Willis said.
-
- Private industries, such as casinos and check-cashing
businesses, have used facial recognition technology for years, but the
software garnered nationwide attention when it was used on more than 100,000
faces at the Super Bowl last year without people's knowledge. No arrests
were made.
-
- Beach police will hear next week whether they'll get
a $150,000 grant, they will ask the City Council to chip in $50,000. If
the money comes through, the program should be up and running by spring
of 2002.
-
- ''It'll be worth it if they get the right people,'' said
Michelle Porter-Loftin, as she shopped with her two children at the Oceanfront.
''Makes me wonder. I'd be worried about mistaken identity. We'll see.''
