A possible solution to protect the copyright of generative models is to watermark the models so that any image generated by the models contain an invisible watermark, whose presence can be checked at a later stage for ownership verification or to trace back the image to the generator which produced…
Facial attributes editing, that is the manipulation of some specific attributes of a face image, is a new trend in the generation of synthetic images by GANs. Several recent studies have shown the possibility to detect the synthetic nature of such images by training a DL-based binary classifier. At…
Recognizing the country where a picture has been taken has many potential applications, such as identification of fake news and prevention of disinformation campaigns. Previous works focused on the estimation of the geo-coordinates where a picture has been taken. Yet, recognizing in which country an…
We investigate if the random feature selection approach proposed in [1] to improve the robustness of forensic detectors to targeted attacks, can be extended to detectors based on deep learning features. In particular, we study the transferability of adversarial examples targeting an original CNN ima…
Recent studies have shown that Convolutional Neural Networks (CNN) are relatively easy to attack through the generation of so called adversarial examples. Such vulnerability also affects CNN-based image forensic tools. Research in deep learning has shown that adversarial examples exhibit a certain d…
We consider a cooperative cognitive wireless network scenario where a primary wireless network is co-located with a cognitive (or secondary) network. In the considered scenario, the nodes of the secondary network make local binary decisions about the presence of a signal emitted by a primary node. T…
