The ACSSECR invention is a biometric access control system and methodology that measures cognitive, psychophysiological responses to stimuli to confirm the identity of an individual. As an alternative to 'Logging in' with a user ID and password, this cognitive biometric authentication system is used for 'Cogging in' to a system with user ID and user-selected 'Cogkey'. ACSSECR is designed for strict access control scenarios where significant authentication confidence is required to gain access to controlled information, facilities, systems, vehicles, or devices. The system takes advantage of a behavioral and physiological characteristic of humans that is an unconscious response to a stimulus. The Event Related Potential (ERP) response (specifically the P3 ERP) involuntarily occurs when an individual perceives and reacts to an unexpected, task-relevant event. The task is for the user to recognize their Cogkey which is presented infrequently amidst more frequent non-target stimuli. There is no requirement for extensive enrollment by users, only the recognition of their Cogkey. The basic system does not store biometric data for comparison, but rather measures the user's Cogkey recognition responses in comparison to non-Cogkey stimulus responses. An individual can have multiple personas with different Cog keys.
