PRNU-based image classification of origin social network with CNN [PDF]
, 2018 A huge amount of images are continuously shared on social networks (SNs) daily and, in most of cases, it is very difficult to reliably establish the SN of provenance of an image when it is recovered from a hard disk, a SD card or a smartphone memory ...

Image Splicing Localization Using A Multi-Task Fully Convolutional Network (MFCN)
, 2017 In this work, we propose a technique that utilizes a fully convolutional network (FCN) to localize image splicing attacks. We first evaluated a single-task FCN (SFCN) trained only on the surface label.
