Deepfake Detection via Exploring Degradation Inconsistency

This research presents a method to detect deepfakes (AI-generated fake videos or images of faces) by identifying inconsistencies in how image quality degrades between the background and the manipulated face regions. The approach uses a framework that learns to spot these degradation differences through two connected neural networks (deep learning models), one that creates fake images and another that detects them, working together in an adversarial process similar to a GAN (generative adversarial network, where two AI systems compete to improve each other). The method shows better performance when detecting deepfakes created by new, unseen manipulation techniques.
