I am dubious about facial recognition by computer in regard to accuracy.
For some reason, I can recognize faces that I have ever seen -- those
that I don't know that sit in a restaurant, those who pass by in a food
supermarket or on a sidewalk, those that I see at a large concert, etc.
-- even for decades later after they age. Not an advantage at all for
me: I can't remember the place that I saw their face, nor can I
remember names of anyone even those that I know well (example: my
mother, my best friend, etc.).
Yesterday I was playing a concert in a local church and was obliged to
sit looking at the congregation. I will always remember the hundreds of
faces that I saw there, but several I have seen somewhere before. One
was a woman that I was unable to decide whether or not I had seen her
face before or whether her face was an identical copy of a movie
actress. Her face not only looked like a face that I remembered, but
also her facial expressions (E.g., she didn't turn her head all the way
to look where she gazed, but tilted her head a bit to the side and
shifted her eyes.) I stared at her face for so long, trying to decide,
actress or not, that she became aware of my stares, and I endeavored to
avert my eyes for the rest of the service.
My point is: even with the best of facial recognition software for the
foreseeable future, there will always be a false identification; and
following a false identification there will be much anguish. There will
be errors especially if the software uses only a still image for
recognition, not a movie that shows changes in facial characteristics in
real situations.

Depends on what database is used to check the face; if FaceBook, I can
see an iPhone app for that.
Thank you,

I think that last one is pretty much out of the question for
"normal" folks. Law enforcement and homeland security interests will
see to that.
Given Google Picassa's facial recognition which works ok and facebook tags
there is a decent chance that a face can be recognized.
