Why does Google+ scan faces in the background?

Question

Android

Hello!
I noticed in the device logs (Nexsus 4 to 5.1) such entries

04-30 14:48:59.778: D/ME(1781): width 208 height 280 scale 4.571429
04-30 14:48:59.778: I/native(1781): motion_stabilization_wrapper.cc:29 Set up RegionFlowComputation
04-30 14 :48:59.778: I/native(1781): motion_stabilization_wrapper.cc:64 Fast tracking activated.
04-30 14:48:59.778: I/native(1781): motion_stabilization_wrapper.cc:69 Set up MotionEstimation
04-30 14:48:59.849: I/async_facetracker(1781): Will wait for the detection to finish.
04-30 14:48:59.849: V/FaceTracker(1781): facemodel: /system/vendor/media/PFFprec_600.emd
04-30 14:48:59.850: V/FaceTracker(1781): modulePath = /system/vendor /media/
04-30 14:48:59.850: V/FaceTracker(1781): ffModule = PFFprec_600.emd
04-30 14:48:59.850: V/FaceTracker(1781): min_eye_dist = 15.000000
04-30 14:48:59.850: V/FaceTracker(1781): roll_range = 45.000000
04-30 14:48:59.850: V/FaceTracker (1781): quality = 0.000000
04-30 14:48:59.850: V/FaceTracker(1781): smoothness = 0.100000
04-30 14:48:59.871: I/async_facetracker(1781): Face detector initialized

The device was in sleep mode at that moment.

04-30 14:46:00.574: I/PowerManagerService(556): Going to sleep due to power button (uid 1000)...
04-30 14:46:00.587: I/PowerManagerService(556): Sleeping (uid 1000 )...

By PID, I found a process that dumped this into the log

u0_a71 1781 198 1598580 103380 ffffffff 00000000 S com.google.android.apps.plus

Why does Google+ scan faces in the background?

Answer 1

The CIA is after you

Answer 2

Collects information.
PS And it also stores your search history, all GPS movements and much more

Answer 3

It also scans your email and follows links in emails. If there is a login and password nearby, then it tries to log in to this site

Answer 4

If you knew even a little bit of English, you would have noticed motion_stabilization_wrapper. For correct stabilization in motion (MotionEstimation), the function of detecting the presence of a face in the image (Face detector) is used. Perhaps some post-processing in the Hyperlapse style is planned to correct the blurring of photos.
And the plus application most likely contains a call to the same function, so that later you can prompt you to mark people in the image. It's not face detection, it's just detecting the presence of a face in an image. Quite a trivial function.
If there was face recognition, then there would be facial recognition in the logs.
In general, I do not think that the phone was asleep at that moment. Keeping the camera on and still processing images is very expensive in terms of resources.
Although it looks like face unlock
