Your Secrets Are Showing: Deep Image Hiding Models Are Surprisingly Easy to Attack

Summary

Researchers asked whether an attacker can identify the content of images hidden by deep image hiding models without knowing which model produced them. They built a dataset of stego images from 11 hiding models and trained a single decoder, based on HiNet, that extracts secret content across unseen models, with humans and machines able to recognize it. The attack also reveals content hidden by AIRPNet, a privacy-oriented image restoration method.
