What to store to Data Base and with what i can compair to take attendance?

[kd1-80587]

the output of this face detection gives json object as LOG faces detected [{"bounds": {"height": 316, "width": 315, "x": 67, "y": 220}, "pitchAngle": 13.571462631225586, "rollAngle": -6.886875152587891, "yawAngle": -3.9724981784820557}] . But its value changes as we move our face then which data I can store to data base to compair and detect face for attendance?

this library is only used to detect faces not to check faces similarity. You need another sollution for this
