Either a photo or a live face How to check the Android camera

Question

I use the Luxand library for face recognition in my Android application. The application has 2 levels for face recognition. 1. In step 1, Open the device’s camera and record the user’s snapshot and save it on your phone. Step 2.Recognition: at this stage, the library recognizes the face. Open the camera and compare with the saved pic.and its performance.

But my problem is at the FaceRecognition stage, when I show the user’s photo in front of the camera, instead show that Live Face recognizes the user. So how to verify that it is a person or a photograph.

Answer 1

I also have a problem with my project. I know that the developer uses a warm camera for this problem. But I heard the library for this problem, now I can’t remember it, if I can add here. It must be a C ++ library. However, it is likely that this library will not work on android, so this is a difficult problem, and, as you know, there are too few arguments on the Internet.
