Abstract
A method for providing a brain computer interface that includes detecting a neural signal of a user in response to a calibration session having a time-locked component and a spontaneous component; generating a user-specific calibration model based on the neural signal; prompting the user to undergo a verification session, the verification session having a time-locked component and a spontaneous component; detecting a neural signal contemporaneously with delivery of the verification session; generating an output of the user-specific calibration model from the neural signal; based upon a comparison operation between processed outputs, determining an authentication status of the user; and performing an authenticated action.
Claims21
A method for providing a brain computer interface comprising:
- within a first time window, detecting a first neural signal of a user in response to a calibration session having at least one of a first time-locked component and a first spontaneous component, wherein the first time-locked component comprises a first randomized factor associated with an unexpected modification to a first percentage of a first stimulus of the calibration session, the first stimulus not pre-selected by the user;
- generating a user-specific calibration model based on a response of the user to the unexpected modification to the first stimulus captured in the first neural signal;
- prompting the user to undergo a verification session within a second time window, the verification session having at least one of a second time-locked component and a second spontaneous component, wherein the second time locked component comprises a second randomized factor occupying a second percentage of a second stimulus of the verification session, the second stimulus not pre-selected by the user;
- detecting a second neural signal contemporaneously with delivery of the verification session;
- generating an output of the user-specific calibration model from the second neural signal;
- based upon a comparison operation between processed outputs of the second neural signal with the output of the user-specific calibration model, determining an authentication status of the user;
- and
- based upon the authentication status, performing an authenticated action.
