RealNetworks has implemented 2 features that help in this scenario:

1. Pose Liveness Detection - Uses a face’s center pose quality to attempt to differentiate between genuine live faces and spoofed fake faces, such as from a video file.

2. 3D Liveness - A special feature of certain Intel RealSense camera models that allows them to distinguish flat images from 3 dimensional ones, thus allowing SAFR to tell the difference between a real face and a video.
