Abstract
The invention relates to a method detecting one or more anomalies regarding logins of a user on an authentication system. The method includes at least one iteration of a monitoring phase that includes collecting a log of successful logins of the user on the authentication system, and calculating, for each monitored parameter, a probability density, in the log, of each predetermined value of the parameter. The method also includes calculating, for each parameter, a weight, as a function of the probability density of each predetermined value of the parameter, calculating an anomaly score for the log as a function of the weights and the probability densities; and comparing the anomaly score to a given threshold in order to determine an anomaly in the daily log for the user. The invention also relates to a computer program product and a device configured to carry out the method.
