US Patent 9185095 Behavioral profiling method and system to authenticate a user

Methods and systems for behavioral profiling are described. In some embodiments, a method includes observing behavioral characteristics of user interactions during a current session with the user through one of a plurality of channels. Variations between the behavioral characteristics of the user interactions observed during the current session and a behavioral profile previously developed based on prior usage patterns of the user through the plurality of channels are identified, in real-time or near real-time. For the user to proceed in the session, a challenge level is implemented based on the variations between the behavioral characteristics and the behavioral profile.
