Once watched a facial recognition system fail to match a driver’s license photo against the driver’s license photo database. Same exact pictures, both digital images that weren’t scanned or anything. Slightly different resolution. Totally failed, repeatedly. A different system, same application round, would flag any man with a beard as a match for Muhammad Al-Sayyid. As a joke one of the techs fed it a photo of Shaggy Rogers and it found multiple “95%+ certainty” matches.
There’s absolutely software that can identify people, some of it deeply scary in how effective it is, but facial ID technology that works with a photo alone is never going to work until we get HD camera footage at eye level installed in every building in the country.
