1. A processor-implemented method for facial recognition, the method comprising: comparing, by a processor, extracted facial features of an input image, provided for recognition, to facial features of each of one or more images in a gallery of known faces, to select a closest gallery image; calculating, by the processor, a first distance between the input image and the selected gallery image; comparing, by the processor, the facial features of the input image to facial features of each of one or more images in a set of decoy faces, to select a closest decoy image; calculating, by the processor, a second distance between the input image and the selected decoy image; and recognizing, by the processor, a match between the input image and the selected gallery image based on a comparison of the first distance and the second distance.
