Abstract : Research performed and results achieved under the DARPA Active Authentication award Investigating Cognitive Rhythms as a New Modality for Continuous Authentication. The research under this project focused on five main tasks: (1) defining and extracting cognitive rhythms (atomic, pausality, linguistic, and revision features) from users' text production data; (2) determining the availability and discriminability of cognitive rhythm features for continuous authentication; (3) determining continuous authentication accuracies of cognitive rhythm features over a large population of users; (4) investigating the impact of non-zero effort forgery attacks against continuous authentication; and (5) prediction of a users' cognitive load levels and demographic information.
