Yes, face recognition is an ACL system. Indeed, a fabulously done ACL
system. Which brings up a fascinating question: if ACLs could solve all
security problems, why did humans invent keys? :-)

Like I said, off-topic but amusing. There are just enough differences
between the physical and computational worlds so that the answer to the
question may well be unuseful, but it is an interesting tack.
