In addition to communication studies, AI research in general, law, and computer science are all concerned with deepfake technologies. However, other disciplines such as journalism studies, cognitive science or even science ethics are also increasingly analyzing the phenomenon. To enable a mutual exchange among the different disciplines as well as the fusion of interdisciplinary knowledge, in phase 2 interdisciplinary research collaborations are established. For this purpose, an interdisciplinary conference is organized, which allows for the exchange of ideas and thought-provoking impulses. It also is the basis for the publication of an interdisciplinary anthology. The interdisciplinary findings on how to deal with deepfakes are additionally forming the basis for the creation of information and educational material for affected stakeholders from the media, education, politics and business (e.g., on the regulation of deepfakes, media literacy).
