in research, typically the behavioral tasks are randomized to avoid this sort of thing. for practical purposes and legal decision-making, i have always envisioned a protocol where the patient is required to repeat back a random string in order to authenticate the system's output. that is, the patient is shown or played a recording of the authentication sequence (by a separate device) and then they must express it through the bci before any device output from that session can be used as communication of intent for legal purposes.
