Patent ID: 8684926

Claim:
A knowledge verification method, comprising presenting probe, relevant, and gallery data to a subject in a statistically weighted, pseudo-random sequence through a data processing and control program operating on a computer; recording, in storage on the computer, a time history of the presentation of the probe, relevant, and gallery data; recording, in storage on the computer, while the subject is experiencing the presentation of the probe, relevant, and gallery data, electrical activity in the subject's brain that is measured by one or more electrodes operatively connected to the computer; analyzing the electrical activity through a neural network operating on the computer to determine if the electrical activity contains one or more p-300 responses; and determining whether any p-300 responses are correlated with the subject experiencing the probe data by comparing, through the data processing and control program operating on the computer, the occurrence of any p-300 responses to the time history of the probe, relevant, and gallery data presented to the subject.
