Question [Q] Weird process running in background

Watching the log file on my nexus 4 I see a strange process running every minute:

Log Tag : async_facetracker
Log message: Face detector initialized

I'm not using any face unlocker or something like that.

Anyone know what is it?

It's Google+.

Call me crazy but I saw it too and got a bit worried.

I have recently flashed my Nexus 4. I didn't even run Google+ once since.
I was debugging my app in Eclipse when suddenly I see thousands of messages in LogCat (see below).

Later I did actually start Google+ and I got the introductory screens that confirms I never ran it before! Including "do you want contact sync" etc.

I have no face-unlock screen either.

So either the phone was capturing my face or was it trying to face-match all my contacts with their database without asking first... what gives??

I saved the full logs but they look just like the sample below. Anyone interested let me know.
