The face recognition system that can determine the real image using a deep learning-based face recognition model that can determine whether it is a real image of a person photographed with a two-dimensional face image is the face image from the face image input to the neural network. a real feature vector extracting unit for extracting at least one of a depth feature vector expressing the depth of an image, a reflection feature vector expressing light reflection of the face image, and an RGB feature vector expressing RGB of the face image; a feature vector fusion unit generating a fusion feature vector by fusing at least one of the depth feature vector and the reflection feature vector with the RGB feature vector; and a determination unit that determines whether the face image is a real image of a person by using the fusion feature vector.
