Abstract
Systems and methods for monitoring user authenticity according to user activities on an application server. A user-modeling process and a user-verification process are performed. In the user-modeling process, a user model is adapted session-by-session to user activities in which the user model includes a plurality of adaptive feature-specific user-behavior models. The user-verification process includes determining a plurality of feature-specific risk-score values, comparing the at least one of the adaptive feature-specific user-behavior models with a respective feature extracted from user activity in the user session on the application server, and determining a total risk-score value indicative of user authenticity by weighting and combining the plurality of feature-specific risk-score values. If the total risk-score value is greater than a given threshold, a corrective action is performed.
