Query: FakeSpotter: A Simple yet Robust Baseline for Spotting AI-Synthesized
  Fake Faces   In recent years, generative adversarial networks (GANs) and its variants have
achieved unprecedented success in image synthesis. They are widely adopted in
synthesizing facial images which brings potential security concerns to humans
as the fakes spread and fuel the misinformation. However, robust detectors of
these AI-synthesized fake faces are still in their infancy and are not ready to
fully tackle this emerging challenge. In this work, we propose a novel
approach, named FakeSpotter, based on monitoring neuron behaviors to spot
AI-synthesized fake faces. The studies on neuron coverage and interactions have
successfully shown that they can be served as testing criteria for deep
learning systems, especially under the settings of being exposed to adversarial
attacks. Here, we conjecture that monitoring neuron behavior can also serve as
an asset in detecting fake faces since layer-by-layer neuron activation
patterns may capture more subtle features that are important for the fake
detector. Experimental results on detecting four types of fake faces
synthesized with the state-of-the-art GANs and evading four perturbation
attacks show the effectiveness and robustness of our approach.
