DeepFake Detection by Analyzing Convolutional Traces
TL;DR: This work focuses on the analysis of Deepfakes of human faces with the objective of creating a new detection method able to detect a forensics trace hidden in images: a sort of fingerprint left in the image generation process.

DeepFake Detection by Analyzing Convolutional Traces
TL;DR: In this paper, an Expectation Maximization (EM) algorithm is proposed to extract a set of local features specifically addressed to model the underlying convolutional generative process. But the proposed technique is limited to face detection.
Journal ArticleDOI
Fighting Deepfake by Exposing the Convolutional Traces on Images
TL;DR: A new approach aimed to extract a Deepfake fingerprint from images is proposed, based on the Expectation-Maximization algorithm trained to detect and extract a fingerprint that represents the Convolutional Traces left by GANs during image generation.
Proceedings ArticleDOI
Preliminary Forensics Analysis of DeepFake Images
TL;DR: A preliminary idea on how to fight Deepfake images of faces will be presented by analysing anomalies in the frequency domain by using standard methods to identify fakeness in images.
Journal ArticleDOI
Fighting deepfakes by detecting GAN DCT anomalies
TL;DR: In this article, a new fast detection method able to discriminate Deepfake images with high precision is proposed by employing Discrete Cosine Transform (DCT), anomalous frequencies in real and Deepfake image datasets were analyzed.
