Homeland Security to test iris scanners
The Homeland Security Department plans to test futuristic iris scan technology that stores digital images of people's eyes in a database and is considered a quicker alternative to fingerprints.
ACLU lawyer Christopher Calabrese fears that the cameras could be used covertly. "If you can identify any individual at a distance and without their knowledge, you literally allow the physical tracking of a person anywhere there's a camera and access to the Internet," he said.
Iris scans can be quicker than fingerprints. "You can walk up to a wall-mounted box, look at the camera, and that's it," Grother said.
Homeland Security will test cameras that take photos from 3 or 4 feet away, including one that works on people as they walk by, Vemury said.
