Abstract

Selon l'invention, une unité de réception (101) reçoit, provenant d'un terminal utilisé par chaque utilisateur d'une pluralité d'utilisateurs, un instant auquel l'utilisateur a effectué une opération prédéterminée sur le terminal. À partir de ces instants reçus, une unité d'acquisition (102) obtient une première distribution temporelle d'événements où l'opération prédéterminée a été effectuée. Une unité de calcul (103) calcule un niveau de coïncidence entre la première distribution temporelle obtenue et l'instant reçu de chaque terminal. Une unité d'estimation (104) estime si chaque utilisateur de la pluralité d'utilisateurs a subi ou non un événement prédéterminé préassocié à l'opération prédéterminée, en fonction du niveau de coïncidence calculé pour l'utilisateur.
