Proteus is an open-source platform for AI content provenance, leveraging perceptual hashing, digital signatures, and MPC/FHE to create incorruptible, private, and robust watermarks. The Proteus paper was presented at ICML 2025 at the CODEML Workshop. The Dinohash perceptual hashing algorithm can be used independently of the Proteus system.
Upload an original image and its edited version to compare their perceptual hashes, including our DinoHash algorithm and previous algorithms. This will help you understand how closely the hashes match, indicating the degree of similarity between the two images.

We retrained the perceptual hashing head on multiple backbones of different models and hash sizes to trace the Pareto frontier between robustness and efficiency. This table shows evaluation time on 12 CPUs and different student-teacher distillations as backbones. Smaller backbones (e.g., Resnets) are faster and lighter for real-time use, while larger backbones (e.g., DinoV2) deliver higher robustness to edits at higher compute cost. The plot below summarizes the trade-off. Feel free to contact us if you want access to other ProteusHash models on the Pareto frontier.
