The boost of available digital media has led to a significant increase in
derivative work. With tools for manipulating objects becoming more and more
mature, it can be very difficult to determine whether one piece of media was
derived from another one or tampered with. As derivations can be done with
malicious intent, there is an urgent need for reliable and easily usable
tampering detection methods. However, even media considered semantically
untampered by humans might have already undergone compression steps or light
post-processing, making automated detection of tampering susceptible to false
positives. In this paper, we present the PS-Battles dataset which is gathered
from a large community of image manipulation enthusiasts and provides a basis
for media derivation and manipulation detection in the visual domain. The
dataset consists of 102'028 images grouped into 11'142 subsets, each containing
the original image as well as a varying number of manipulated derivatives.Comment: The dataset introduced in this paper can be found on
