Biometric security systems such as Apple’s FaceID have replaced passwords for mobile device security, leav- ing users susceptible to biometric spoofing attacks. In response, Apple has implemented an anti-spoofing scheme, looking for autonomous ocular movement associated within the retina. This research aims to quantify the effective- ness of 3D printed spoof masks in regards to defeating a biometric anti-spoofing system such as Apple’s iPhone X. 3D facial spoofs were created and tested using the iPhone X through 3D printing techniques and live cast- ing. The 3D printed face masks were created from a 3D image utilizing a volumetric regression network. A series of anti-spoofing techniques were used as testing validation. These techniques range from measuring the thermal retention rate, stereoscopic facial image dispar- ity map comparisons between a live face, and a spoof image, and implementation of multitask cascaded con- volutional network for recognition of key facial features.
