Risk based authentication is an approach to authenticate user based on risk score assigned to used based on previous authentication history. It is adaptive authentication in which based on risk score user is asked for additional authentication steps, if risk score is low, user will be allowed to login frictionless. The purpose of this study is to classify users based on risk in authentication as HIGH/LOW risk using K nearest neighbour algorithm and check the accuracy results of the KNN algorithm for the risk based authentication classification of genuine vs fraud login attempt.
