DEEP-PRISMA investigates the growing risks of abusive deepfakes, focusing in particular on the ethical challenges they pose for citizens' informational self-determination and personal rights. The project combines empirical research with legal and ethical reflection to analyse how sexualised, fraudulent and defamatory deepfakes affect those involved, how effective existing protective mechanisms are, and where normative, legal and technical gaps exist. The aim is to empower people to know and protect their rights, while developing ethically and legally sound recommendations for responsible regulation, value-oriented technology design and accompanying social measures that safeguard democratic principles and privacy in a world shaped by AI.
