Descripción del proyecto
Mejorar la privacidad de los datos en el aprendizaje federado con métodos nuevos
A fin de abordar las vulnerabilidades de la privacidad del aprendizaje federado, en el proyecto TRUMPET, financiado con fondos europeos, se llevará a cabo una investigación para identificarlas y se desarrollarán nuevas tecnologías de mejora de la privacidad que contribuyan a su mitigación. Su equipo también se propone crear una plataforma de servicios de inteligencia artificial (IA) federada escalable que no solo mejorará la privacidad de los datos en general, sino que además permitirá a los investigadores realizar estudios empleando la IA en conjuntos de datos europeos con mayor privacidad. Para demostrar la seguridad del nuevo método, se contratará a expertos y organizaciones de terceros para probar y mejorar la plataforma en dos casos de uso de aprendizaje federado en sanidad electrónica.
Objetivo
In recent years, Federated Learning (FL) has emerged as a revolutionary privacy-enhancing technology and, consequently, has quickly expanded to other applications.
However, further research has cast a shadow of doubt on the strength of privacy protection provided by FL. Potential vulnerabilities and threats pointed out by researchers included a curious aggregator threat; susceptibility to man-in-the-middle and insider attacks that disrupt the convergence of global and local models or cause convergence to fake minima; and, most importantly, inference attacks that aim to re-identify data subjects from FL’s AI model parameter updates.
The goal of TRUMPET is to research and develop novel privacy enhancement methods for Federated Learning, and to deliver a highly scalable Federated AI service platform for researchers, that will enable AI-powered studies of siloed, multi-site, cross-domain, cross border European datasets with privacy guarantees that exceed the requirements of GDPR. The generic TRUMPET platform will be piloted, demonstrated and validated in the specific use case of European cancer hospitals, allowing researchers and policymakers to extract AI-driven insights from previously inaccessible cross-border, cross-organization cancer data, while ensuring the patients’ privacy. The strong privacy protection accorded by the platform will be verified through the engagement of external experts for independent privacy leakage and re-identification testing.
A secondary goal is to research, develop and promote with EU data protection authorities a novel metric and tool for the certification of GDPR compliance of FL implementations.
The consortium is composed of 9 interdisciplinary partners: 3 Research Organizations, 1 University, 3 SMEs and 2 Clinical partners with extensive experience and expertise to guarantee the correct performance of the activities and the achievement of the results.
