Abstract: A method and apparatus to control operation of a brain-computer interface, comprising: capturing, at a sensor, a time series of brain activity in response to stimuli; passing data for the time series of brain activity to a history-based challenge generator; receiving, from the history-based challenge generator, a challenge comprising a generated stimulus with a predicted brain response derived from data for the time series of brain activity; issuing the challenge over the brain-computer interface; capturing, at the sensor, a brain response to the challenge; comparing, by an authenticator, the brain response to the challenge with the predicted brain response for the generated stimulus; and responsive to finding no match between the brain response to the challenge and the predicted brain response, preventing further activity over the brain-computer interface.
