Description du projet
Des services Internet avec une protection intégrée de la vie privée
Chaque fois qu’une personne utilise Internet, elle doit confier ses données à un fournisseur unique de services. Cela présente un risque, car de nombreux fournisseurs de services sont situés en dehors de l’UE, et il y a eu de nombreux incidents au cours desquels des gouvernements, des agresseurs (externes ou internes) ou des erreurs humaines ont laissé fuiter des données d’utilisateurs. L’UE a pris des mesures pour prévenir les attaques de ce type, principalement en appliquant le règlement général sur la protection des données (RGPD), qui oblige les entreprises à protéger efficacement les informations personnelles de leurs utilisateurs. Le projet PSOTI, financé par l’UE, fournira une protection supplémentaire en appliquant non seulement des mesures légales, mais aussi techniques lors du traitement des données sensibles des utilisateurs. Concrètement, un cadre sera développé qui permettra aux utilisateurs de choisir parmi plusieurs fournisseurs de services. Les fournisseurs de services sélectionnés traitent ensuite conjointement les données des utilisateurs, afin qu’elles restent protégées.
Objectif
Today, when using services on the Internet, users have to fully entrust a single service provider with their data. Many of these service providers are located outside the EU and there are cases where data has not only been leaked by attacks of outsiders or insiders, but also by governments who built backdoors into software or hardware, or forced service providers to give out sensitive user data. With the new EU General Data Protection Regulation (GDPR) also companies have an obligation to properly protect users’ data. My project PSOTI will eliminate the need to trust a single service provider and empower users to freely control their data. For this, the users can choose a subset of multiple service providers that they are willing to trust who jointly process their data and privacy is guaranteed even if all but one are compromised. The main goal of PSOTI is to develop privacy-preserving services for commonly used tasks on the Internet that are feature-rich and efficient enough for practical use. This will allow to privately store, retrieve, search, and process data, and help to comply with the GDPR and preserve the fundamental rights to privacy and the protection of personal data. As underlying technology, we will build a real-world secure multi-party computation (MPC) framework that can also be used for other large-scale privacy-preserving applications such as genomics or machine learning. To achieve our main goal, we will solve the following challenges: 1) Develop private query protocols on outsourced data that process complex queries such as Boolean formulas over string matches or range queries, and even hide the query’s structure. 2) Build a real-world MPC framework that scales to large functionalities, is highly parallelized, interoperable, and fully integrated. 3) Demonstrate real-world applicability for privacy-preserving and feature-rich services on the Internet such as file storage (going beyond Dropbox), surveys (going beyond Google Forms), and email.
