In plain words: A trained generator makes fake face photos that look different from a real person's photo yet produce nearly the same numbers the system uses to compare faces. The fakes passed a custom face check and, tested without access to the app's code, dating apps' verification.
Abstract · Face Verification Bypass
Face verification systems aim to validate the claimed identity using feature vectors and distance metrics. However, no attempt has been made to bypass such a system using generated images that are constrained by the same feature vectors. In this work, we train StarGAN v2 to generate diverse images based on a human user, that have similar feature vectors yet qualitatively look different. We then demonstrate a proof of concept on a custom face verification system and verify our claims by demonstrating the same proof of concept in a black box setting on dating applications that utilize similar face verification systems.
