face recognition software.....

ok, so i have been troubled since my first eku class....there are a handful of folks enrolled that look so very familiar....and who i cannot place......and i really could use some sort of high tech recognition program to idientify time and place without having to ask......because in asking one acknowledges that one is a daft old woman who cannot recall simple things....like where she should know you from......the most pressing identification came easily......i said innocently...'i can't put a place with your face and she laughed and explained that she used to color her hair, and that most people don't recognize her with the grey......the other person knew who i am through mutual friends, but declined to tell me if we had ever actually met...drat...i will fret until i figure this out.......
