Decision-based iterative fragile watermarking for model integrity verification

no code implementations13 May 2023 Zhaoxia Yin, Heng Yin, Hang Su, Xinpeng Zhang, Zhenzhe Gao

Our method has some advantages: (1) the iterative update of samples is done in a decision-based black-box manner, relying solely on the predicted probability distribution of the target model, which reduces the risk of exposure to adversarial attacks, (2) the small-amplitude multiple iterations approach allows the fragile samples to perform well visually, with a PSNR of 55 dB in TinyImageNet compared to the original samples, (3) even with changes in the overall parameters of the model of magnitude 1e-4, the fragile samples can detect such changes, and (4) the method is independent of the specific model structure and dataset.
