Facial recognition systems exhibit varying levels of performance depending on demographic characteristics such as gender, age, or ethnic origin. These biases, extensively documented in empirical studies, raise critical concerns regarding reliability, fairness, and ethical compliance. This presentation will examine the underlying sources of these biases, whether they stem from dataset composition, algorithmic choices, or intersectional … Continue reading Neily Sanon – L’identification et la mesure des biais dans les systèmes de reconnaissance facial

Post-quantum digital signatures have sparked a lot of interest in the cryptographic community in recent years. Both the NIST-selected signature Dilithium and Heatae, winner of the Korean PQC competition, rely on hardness of lattice problems and employ the Fiat-Shamir with Aborts paradigm, in which rejection sampling is used to eliminate a secret’s dependency on a … Continue reading Henry Bambury – Polytopes in the Fiat-Shamir with Aborts Paradigm
