Face recognition systems are widely known for their vulnerability against presentation attacks or spoofing attacks. The exponential deployment of face recognition systems has been further challenged even by the simple and low-cost face artefacts generated using conventional printers. In this paper, we present a novel scheme to detect face presentation attacks posed by high-quality print attacks which are relatively difficult to detect. The proposed scheme leverages the phase information extracted from the spatial-frequency representation of the given image. We also present a new face presentation attack database collected using the iPhone 6S. The new database is comprised of 100 subjects collected in two different sessions that have resulted in a total of 31228 samples (or images). Extensive experiments are carried out on the newly constructed database and the obtained results show the improved performance of the proposed scheme when compared aaainst six different state-of-the-art methods.
