Towards a Governance Framework for Brain Data

no code implementations24 Sep 2021 Marcello Ienca, Joseph J. Fins, Ralf J. Jox, Fabrice Jotterand, Silja Voeneky, Roberto Andorno, Tonio Ball, Claude Castelluccia, Ricardo Chavarriaga, Hervé Chneiweiss, Agata Ferretti, Orsolya Friedrich, Samia Hurst, Grischa Merkel, Fruzsina Molnar-Gabor, Jean-Marc Rickli, James Scheibner, Effy Vayena, Rafael Yuste, Philipp Kellmeyer

The increasing availability of brain data within and outside the biomedical field, combined with the application of artificial intelligence (AI) to brain data analysis, poses a challenge for ethics and governance.

Constrained Differentially Private Federated Learning for Low-bandwidth Devices

no code implementations27 Feb 2021 Raouf Kerkouche, Gergely Ács, Claude Castelluccia, Pierre Genevès

This bandwidth and corresponding processing costs could be prohibitive if the participating entities are, for example, mobile devices.

Compression Boosts Differentially Private Federated Learning

no code implementations10 Nov 2020 Raouf Kerkouche, Gergely Ács, Claude Castelluccia, Pierre Genevès

In this paper, compressive sensing is used to reduce the model size and hence increase model quality without sacrificing privacy.

Federated Learning in Adversarial Settings

no code implementations15 Oct 2020 Raouf Kerkouche, Gergely Ács, Claude Castelluccia

This paper presents a new federated learning scheme that provides different trade-offs between robustness, privacy, bandwidth efficiency, and model accuracy.

Differentially Private Mixture of Generative Neural Networks

no code implementations13 Sep 2017 Gergely Acs, Luca Melis, Claude Castelluccia, Emiliano De Cristofaro

We model the generator distribution of the training data with a mixture of $k$ generative neural networks.

When Privacy meets Security: Leveraging personal information for password cracking

2 code implementations24 Apr 2013 Claude Castelluccia, Abdelberi Chaabane, Markus Dürmuth, Daniele Perito

In extensive experiments we show that it can crack up to 69% of passwords at 10 billion guesses, more than all probabilistic password crackers we compared again t. Second, we systematically analyze the idea that additional personal information about a user helps in speeding up password guessing.
