Find my Face is the Newest Feature that Google+ is getting which is related with the Facial recognition basically allowing and making Photo tagging easier on Google+ .
This feature is completely on user based choice and Google+ does not forces you to use it !
Matt Steiner , Engineer Lead of the Google+ Photos team said that in a Post on the Official Google+ page that ," Around the holidays, many of us get together with friends and family, and if you’re like me, you take lots of photos! Tagging those photos can be a lot of work. So today we’re launching Find My Face, an easier way to tag photos of yourself and your friends.
By turning on Find My Face, Google+ can prompt people you know to tag your face when it appears in photos. Of course, you have control over which tags you accept or reject, and you can turn the feature on or off in Google+ settings.
Find My Face will be rolling out over the next few days. We hope this makes tagging your photos much easier, so try it out! And as always, keep the feedback coming. "
However this feature is disabled in Google settings by default and you have to manually enable it by moving to the settings page :-

After the enormous privacy concerns came when Facebook was under the scanner regarding Photos posted on Facebook which made it to add Facial recognition , Google+ is also now in this era !
