Cognitive fraud prevention

Abstract:

A computer implemented method for preventing fraudulent activity on a user account includes analyzing a set of personal information corresponding to a user to identify one or more travel events, wherein each travel event indicates a corresponding timeframe and location, receiving an access attempt made with respect to a user account and a current location corresponding to the access attempt, determining whether the current location corresponds to a location indicated by the one or more identified travel events, analyzing one or more external sources to determine whether the current location is explainable responsive to determining the current location does not correspond to a location indicated by the one or more identified travel events, and denying the received access attempt made with respect to the user account responsive to determining the current location is not explainable.
