I've never took any action it just recognizes faces of those ive taken a good amount of pics with and shows them in my network including automatically naming some of them. Tho not all of them seen under People & Pets have their name automatically listed. But and again it automatically already knows whose in my network so if I take a pic of them using my Apple Glasses the glasses tech or app on iPhone could have the pic focused on them and either blur out others in public or anonmyize/randomize all other faces. This is just an idea that would help solve people's concern with smart glasses and Apple is the privacy company.
