Application of Machine Learning to User Behavior-Based Authentication in Smartphone and Web

Authentication is the preliminary security mechanism employed in information system to identify legitimacy of user. With technological advancements, hackers with sophisticated techniques easily crack single-factor authentication (username and password). Therefore, organizations started deploy multi-factor (MFA) increase complexity access system. Despite MFA increasing digital service, usable should be given equal importance. The user behavior-based provides a means analyze interaction non-intrusive way legitimacy. This chapter presents review smartphones websites. Moreover, highlights some common features, techniques, evaluation criteria usually considered development behavior profiling.
