Over the past few years, AI methods of generating images have been increasing
in capabilities, with recent breakthroughs enabling high-resolution,
photorealistic "deepfakes" (artificially generated images with the purpose of
misinformation or harm). The rise of deepfakes has potential for social
disruption. Recent work has proposed using ZK-SNARKs (zero-knowledge succinct
non-interactive argument of knowledge) and attested cameras to verify that
images were taken by a camera. ZK-SNARKs allow verification of image
transformations non-interactively (i.e., post-hoc) with only standard
cryptographic hardness assumptions. …
