Fleming-Viot Selection of the Yaglom Limit for Age-Structured Bellman-Harris Processes, with Application to Livestock Epidemic Surveillance
Ouerdia Arezki, Paul-Marie Grollemund, Ali Zemouche
In this paper, we construct a Fleming-Viot particle system for a class of subcritical Bellman-Harris processes. We prove that it selects the Yaglom limit at a polynomial rate in th…
Accuracy Limits as a Barrier to Biometric System Security
Axel Durbet, Paul-Marie Grollemund, Pascal Lafourcade +1
Biometric systems are widely used for identity verification and identification, including authentication (i.e., one-to-one matching to verify a claimed identity) and identification…
Sparse inference in Poisson Log-Normal model by approximating the L0-norm
Togo Jean Yves Kioye, Paul-Marie Grollemund, Jocelyn Chauvet +3
Variable selection methods are required in practical statistical modeling, to identify and include only the most relevant predictors, and then improving model interpretability. Suc…
Exploit the Leak: Understanding Risks in Biometric Matchers
Axel Durbet, Kevin Thiry-Atighehchi, Dorine Chagnon +1
In a biometric authentication or identification system, the matcher compares a stored and a fresh template to determine whether there is a match. This assessment is based on both a…
Untargeted Near-collision Attacks on Biometrics: Real-world Bounds and Theoretical Limits
Axel Durbet, Paul-Marie Grollemund, Kevin Thiry-Atighehchi
A biometric recognition system can operate in two distinct modes: identification or verification. In the first mode, the system recognizes an individual by searching the enrolled t…
Near-collisions and their Impact on Biometric Security
Axel Durbet, Paul-Marie Grollemund, Pascal Lafourcade +1
Biometric recognition encompasses two operating modes. The first one is biometric identification which consists in determining the identity of an individual based on her biometrics…
Authentication Attacks on Projection-based Cancelable Biometric Schemes
Axel Durbet, Pascal Lafourcade, Denis Migdal +2
Cancelable biometric schemes aim at generating secure biometric templates by combining user specific tokens, such as password, stored secret or salt, along with biometric data. Thi…
Bayesian functional linear regression with sparse step functions
Paul-Marie Grollemund, Christophe Abraham, Meïli Baragatti +1
The functional linear regression model is a common tool to determine the relationship between a scalar outcome and a functional predictor seen as a function of time. This paper foc…
