Abstract[English]
The invention relates to technologies for detecting fraudulent serial user verification requests. A method for detecting anomalies in groups of users' verification requests performed by a processor comprises the following steps: receiving users' verification requests and user's device identifying parameters; generating device fingerprint; grouping verification requests; within the group of verification requests with matching device fingerprints searching for verification requests that match by at least one additional attribute of the request; in response to identifying a match of at least one additional attribute, marking the whole group as anomalous, in response to identifying a match of said additional attribute of the request in a subgroup within said group, marking such subgroup as anomalous; otherwise, marking the verification requests for which no coinciding additional attribute of the request has been found as non anomalous.[French]
L'invention concerne des technologies de détection de demandes frauduleuses en série d’authentification d’utilisateur. Un procédé de détection d'anomalies dans des groupes de demandes d’authentification d’utilisateurs mis en œuvre par un processeur comprend les étapes suivantes : réception de demandes d’authentification d’utilisateurs et de paramètres d'identification du dispositif de l'utilisateur ; génération d'une empreinte digitale de dispositif ; regroupement de demandes d’authentification ; à l'intérieur du groupe de demandes d’authentification dont les empreintes de dispositif concordent, recherche des demandes d’authentification qui concordent par au moins un attribut supplémentaire de la demande ; en réponse à l'identification d'une concordance d'au moins un attribut supplémentaire, marquage de l'ensemble du groupe comme anormal, en réponse à l'identification d'une concordance dudit attribut supplémentaire de la demande dans un sous-groupe à l’intérieur dudit groupe, marquage dudit sous-groupe comme anormal ; sinon, marquage des demandes d’authentification pour lesquelles aucun attribut supplémentaire coïncidant de la demande n'a été trouvé comme non anormales.
