DFREC: DeepFake Identity Recovery Based on Identity-Aware Masked Autoencoder

DFREC is a new method for identifying the original faces used to create deepfakes (fake videos where one person's face is swapped onto another's body). Unlike existing deepfake detection tools that only identify whether an image is fake, DFREC recovers both the source face (the one being used) and target face (the one being impersonated) from a deepfake image, which helps investigators trace who was involved in creating the fake and reduces risks from deepfake attacks. The system uses three components: one to separate source and target face information, one to reconstruct the source face, and one to reconstruct the target face using a Masked Autoencoder (a type of neural network that learns patterns by hiding parts of input data).
