mattnyc99 writes: The FBI has confirmed to Popular Mechanics that it's not only adding palm prints to its criminal records, but preparing to balloon its repository of photos, which an agency official says "could be the basis for our facial recognition." It's all part of a new biometric software system that could store millions of iris scans within 10 years and has privacy advocates crying foul. Quoting: "The FBI's Next Generation Identification (NGI) system, which could cost as much as $1 billion over its 10-year life cycle, will create an unprecedented database of biometric markers, such as facial images and iris scans. For criminal investigators, NGI could be as useful as DNA some day — a distinctive scar or a lopsided jaw line could mean the difference between a cold case and closed one. And for privacy watchdogs, it's a duel threat — seen as a step toward a police state, and a gold mine of personal data waiting to be plundered by cybercriminals."
