I work on a facial recognition program by taking a facial image from a mobile camera...

the problem is that the user can take a picture from the camera and not a picture of his real face
Is there a way to know that the captured image is "real" and not a picture from a previously captured photo?

What I have tried:

I am thinking of a filter to distinguish the captured image whether it is two-dimensional or three-dimensional

Unless you are using a depth camera, you can't differentiate between a 2D face and a 3D face - you lack the depth information to calculate this.
