1. A computer-implemented method comprising:
obtaining a first image captured using a first camera disposed on a first side of a mobile device, the first image including representation of reflections visible on corneas of a subject;
obtaining a second image captured using a second camera disposed on a second side of the mobile device, the second side being on the opposite side of the first side;
pre-processing the first image and the second image to generate a third image and a fourth image, respectively, wherein a first field of view represented in the third image at least partially overlaps with a second field of view of the fourth image;
determining, based on the third and fourth images, that a scene represented in the first field of view is substantially same as a scene represented in the second field of view; and
in response to determining that the scene represented in the first field of view is substantially same as the scene represented in the second field of view, identifying the subject as a live person.
