Detection of GAN-Generated Fake Images over Social Networks
TL;DR: In this paper, the performance of several image forgery detectors against image-to-image translation, both in ideal conditions, and in the presence of compression, was studied. But only the latter keep providing a high accuracy, up to 89%, on compressed data.
Journal ArticleDOI
An Investigation of Local Descriptors for Biometric Spoofing Detection
TL;DR: Assessment of the potential of local descriptors, based on the analysis of microtextural features, for the liveness detection task in authentication systems based on various biometric traits, and points out possible lines of development toward further improvements.

Do GANs leave artificial fingerprints
TL;DR: It is shown that each GAN leaves its specific fingerprint in the images it generates, just like real-world cameras mark acquired images with traces of their photo-response non-uniformity pattern.

Local contrast phase descriptor for fingerprint liveness detection
TL;DR: Experiments on the publicly available LivDet 2011 database, comprising datasets collected from various sensors, prove the proposed method to outperform the state-of-the-art liveness detection techniques.
