The FBI has quietly been expanding a 2013 pilot program which has
reportedly collected scans of irises belonging to over 400,000 arrestees
to date. The program is part of of the FBI’s “Next Generation
Identification” initiative. While the bureau has made no secret of its interest in biometrics,
the fact that it has already amassed a collection of hundreds of
thousands of unique iris scans was only recently made public, thanks to
an exhaustive report by The Verge.
