Such a system won't need a single ID photo as 'reference'. When it notices someone leaving a house on Wisteria Lane 2401, and walking into an office on 21 Main Street, and there are postal packages send to John Smith on Wisteria Lane 2401 and social security contributions for employee John Smith by an employer registered at 21 Main Street, it doesn't take much to put 2 and 2 together and conclude that the face of that person is that of John Smith. And that's just 2 data points - think about it, how many things are there that tie a person to a name and a location? How irregular are people's movements really? Apart from putting on another mask every day, and moving house every few days, given enough processing power and some time that future system will recognize all but the most determined individuals - although I don't see how anyone can live a 'normal' life without a fixed address, job, phone, internet use, and 0 tolerance for anything that resembles a 'routine'.
