Deepfakes and the right to one’s own image: How you can protect yourself
A group photo on Instagram, a photo of an employee at a company party, a video manipulated using AI: Such situations are commonplace today, and the legal issues they raise are anything but trivial. Every person has the right to determine what happens to their image, whether it be a photograph, video or digital representation. This so-called right to one’s own image is not a matter of course, but a legally protected asset that is firmly enshrined in Swiss personality rights. Anyone who uses, exploits or disseminates another person’s image without their consent is, in principle, acting unlawfully. The Swiss legal system offers a multi-layered protection system through Art. 28 of the Swiss Civil Code (CC), Art. 179quater of the Swiss Criminal Code (SCC) and the revised Data Protection Act, although the limits of this system are tested daily in the digital sphere.
