Hi,

Looks like the DOD has confirmed once again that face scanning only
works about 50% of the time under best case conditions.  My assumption
here is that the DOD was testing face scanning in an authentication
application which means they had good database photos.  A face scanning
system looking for terrorist probably doesn't have the luxury of good
database photos, so its success rate will be even lower.

At a biometrics conference on Friday, Defense Department official Steven
King said that of the 270 persons checked by the Visionics system, it
correctly recognized individuals a mere 51 percent of the time, and
identified an individual to within a range of 10 participants 81 percent
of the time. The supposedly more reliable Iridian eye-scanners,
meanwhile, correctly verified someone's identity just 94 percent of the
time.
