Research Reveals the Limits of Traceability Watermarks in Fine-tuned Image Generators
A new AI study maps out how well watermarks hidden in the training data of image generators actually work when models are fine-tuned to replicate specific faces or art styles.
The idea of so-called dataset watermarking is to embed an invisible mark to the human eye in the training images. This watermark accompanies the model's learning and is recognizable in the new images produced by the model. The method has been hoped to provide a solution for monitoring copyright and security as more AI models are customized with private image datasets.
The research by Xincheng Wang and an international team brings together a fragmented field and proposes a general threat model and a comprehensive evaluation framework. Watermarks are examined through three characteristics: generality (does the method work with different datasets and models), transferability (does the watermark reliably transfer from training images to produced images), and robustness (does the watermark remain when images are edited or attempts are made to clean them).
The experiments in the study show that current dataset watermarks achieve quite good results in both generality and transferability. They also withstand to some extent common image editing operations, such as typical processing done to images online.
At the same time, the study reveals clear limitations: the robustness of watermarks weakens when they are attacked more systematically. The team also presents a method for removing watermarks, as mentioned in the headline, and incorporates it into the threat model, but the summary does not yet detail its results.
The results emphasize that dataset watermarks are a promising but still incomplete tool for tracing the origin and copyrights of AI models at a time when image generators are increasingly fine-tuned with private image datasets.
