Zusammenfassung:The invention relates to a method for detecting fraudulent transactions in a collection of payment transactions, consisting in submitting the transactions to a classification system trained on an training set and providing for each new transaction of said collection a probability of being a fraudulent transaction, characterized in that with each transaction is associated contextual information, and in that the classification system is a neural network. L'invention concerne un procédé de détection de transactions frauduleuses dans un ensemble de transactions de paiement, consistant à soumettre les transactions à un système de classification entrainé sur un jeu d'entrainement et fournissant pour chaque nouvelle transaction dudit ensemble une probabilité d'être une transaction frauduleuse, caractérisé en ce qu'à chaque transaction sont associées des informations contextuelles, et en ce que le système de classification est un réseau de neurones.
