Abstract
Method for improving user authentication efficiency performed by a communication device belonging to an authentication system. The communication device includes a local machine learning engine having a set of N artificial neural network ANN1,i adapted to process N different types of input signals. The method includes the steps: receiving a first set of N input signals S_1(i) for authentication purpose; determining respectively for each of the N input signals S_1(i) by the N artificial neural networks ANN1,i, N estimations LH(i) of the likelihood that a given input signal is provided by a legitimate user; determining based on a risk scoring established using the N estimations LH(i) if the requesting user is authenticated as the legitimate user; if the requested user is authenticated, determining if at least one likelihood estimation determined for a given input signal S_1(j) is below a predetermined threshold TC,i, and if it is the case: transmitting the input signal S_1 (j) to a remote server implementing a server machine learning engine adapted to process said N different types of input signals and trained to identify a user U_C; receiving an input signal S_2(j) associated to the …
