Video Seal: Open and Efficient Video Watermarking

1 code implementation12 Dec 2024 Pierre Fernandez, Hady Elsahar, I. Zeki Yalniz, Alexandre Mourachko

To reduce these gaps, this paper introduces Video Seal, a comprehensive framework for neural video watermarking and a competitive open-sourced model.

Watermark Anything with Localized Messages

1 code implementation11 Nov 2024 Tom Sander, Pierre Fernandez, Alain Durmus, Teddy Furon, Matthijs Douze

Image watermarking methods are not tailored to handle small watermarked areas.

Evaluation of Security of ML-based Watermarking: Copy and Removal Attacks

1 code implementation26 Sep 2024 Vitaliy Kinakh, Brian Pulfer, Yury Belousov, Pierre Fernandez, Teddy Furon, Slava Voloshynovskiy

While the robustness of these systems is well-documented, the security against adversarial attacks remains underexplored.

Log-normal Mutations and their Use in Detecting Surreptitious Fake Images

no code implementations23 Sep 2024 Ismail Labiad, Thomas Bäck, Pierre Fernandez, Laurent Najman, Tom Sander, Furong Ye, Mariia Zameshina, Olivier Teytaud

We apply the log-normal method to the attack of fake detectors, and get successful attacks: importantly, these attacks are not detected by detectors specialized on classical adversarial attacks.

Watermarking Makes Language Models Radioactive

1 code implementation22 Feb 2024 Tom Sander, Pierre Fernandez, Alain Durmus, Matthijs Douze, Teddy Furon

We discover that, on the contrary, it is possible to reliably determine if a language model was trained on synthetic data if that data is output by a watermarked LLM.

Proactive Detection of Voice Cloning with Localized Watermarking

1 code implementation30 Jan 2024 Robin San Roman, Pierre Fernandez, Alexandre Défossez, Teddy Furon, Tuan Tran, Hady Elsahar

In the rapidly evolving field of speech generative models, there is a pressing need to ensure audio authenticity against the risks of voice cloning.

Functional Invariants to Watermark Large Transformers

no code implementations17 Oct 2023 Pierre Fernandez, Guillaume Couairon, Teddy Furon, Matthijs Douze

The rapid growth of transformer-based models increases the concerns about their integrity and ownership insurance.

Three Bricks to Consolidate Watermarks for Large Language Models

3 code implementations26 Jul 2023 Pierre Fernandez, Antoine Chaffin, Karim TIT, Vivien Chappelier, Teddy Furon

The task of discerning between generated and natural texts is increasingly challenging.

The Stable Signature: Rooting Watermarks in Latent Diffusion Models

2 code implementations ICCV 2023 Pierre Fernandez, Guillaume Couairon, Hervé Jégou, Matthijs Douze, Teddy Furon

For instance, it detects the origin of an image generated from a text prompt, then cropped to keep $10\%$ of the content, with $90$+$\%$ accuracy at a false positive rate below 10$^{-6}$.

Active Image Indexing

1 code implementation5 Oct 2022 Pierre Fernandez, Matthijs Douze, Hervé Jégou, Teddy Furon

First, a neural network maps an image to a vector representation, that is relatively robust to various transformations of the image.

Watermarking Images in Self-Supervised Latent Spaces

1 code implementation17 Dec 2021 Pierre Fernandez, Alexandre Sablayrolles, Teddy Furon, Hervé Jégou, Matthijs Douze

We revisit watermarking techniques based on pre-trained deep networks, in the light of self-supervised approaches.
