Confidential Inference and Explainability: Toward Self-Diagnosis via Imaging

This PhD topic aims to jointly address privacy and explainability of decisions obtained through image analysis using a neural network. In the context of a classification task performed on a remote server, the goal is to develop approaches that ensure the confidentiality of the explanation as well as that of the input (and output) data. Preserving the privacy of data while ensuring the transparency of the model is a crucial challenge, particularly in domains such as healthcare. The objective aligns with the emerging regulatory framework on AI at the European level (AI Act). While these issues are the subject of significant research individually - whether in applied cryptography or machine learning - the combination of explainability under privacy constraints represents a new research problem. The project will seek to identify local explainability methods based on visual information or concepts that can be adapted to a privacy-preserving mode. Confidentiality may be approached through secure multi-party computation and/or homomorphic encryption. Thanks to a collaboration with the Saint-Etienne University Hospital (France), it will be possible to fine-tune the secure AI system and conduct supervised experiments on health data, aimed at enabling self-diagnosis. The experimentation may also extend to ethical and legal dimensions, through a partnership with the University of Ottawa.

PhD Location: Laboratoire Hubert Curien (LabHC), Université Jean Monnet, Saint-Etienne, France (regular meetings at the CITI Laboratory, INSA Lyon, Villeurbanne, France).

Starting date: 01/10/2025.

The zero-knowledge group (a subgroup of the cryptography group) at the Institute of Computer Science of the University of Tartu seeks one postdoctoral researcher and one Ph.D student in contemporary zk-SNARKs. The existing zero-knowledge group comprises Helger Lipmaa, Janno Siim, and Ph.D students. Our current research interests include the provable security of zk-SNARKs (including more stringent security notions and more realistic cryptographic assumptions), the design of pairing-based, code-based, and lattice-based zk-SNARKs, and the design of zk-SNARKs for applications like zkVM and zkML. We collaborate actively with local groups on coding theory and machine learning to further our aims. While primarily focused on academic publishing, we are interested in collaborating with ZK companies.

The postdoctoral researcher should have a strong track record in areas related to the design and analysis of efficient zero-knowledge proofs. We expect the candidate to have published a few papers at IACR conferences or venues of equivalent renown. The Ph.D student must have an MSc or equivalent by this spring, a strong mathematics and/or theoretical computer science background, and an existing cryptography background. We welcome all exceptional candidates. We especially welcome candidates with a background in PQ zk-SNARKs (hash-based or lattice-based) or applications like zkML; in the case of the Ph.D student, we interpret it as a background either in coding theory, lattice-based cryptography, or machine learning.

T apply for the positions, submit a letter of motivation (clearly stating why this project and the applicant are a good match), a full research CV, names of two references, and a research statement (obligatory for the postdoctoral researcher), clearly indicating the sought position (postdoc or Ph.D student).

The postdoc position starts on August 1, 2025, or later and lasts 2-4 years, depending on the candidate and negotiations. The Ph.D. position starts on September 1, 2025, and lasts four years. The candidates may later seek further employment, but this is not guaranteed in advance. Application deadline: 25.04.2025.
