Abstract

Systems and methods securely authenticate an identity of an individual based on a pattern that is traced by the individual. Embodiments relate to prompting an individual with a pattern to trace when attempting to authenticate the identity of the individual during an identity authentication session. Motion-based behavior data that is generated by motions executed by the individual as the individual traces the pattern is captured via a motion-capturing sensor. The motion-based behavior data is unique to the individual and has a low likelihood of being duplicated by an unauthorized individual attempting to fraudulently pose as the individual. The captured motion-based behavior data is compared to previously-captured motion-based behavior data from previous traces of the pattern completed by the individual. The identity of the individual is authenticated when the motion-based behavior data is within a threshold of the previously captured motion-based behavior data.
