1. A method of confirming an identity of a user, comprising:
displaying a first visual indicator, wherein the first visual indicator is flashing at a first frequency to induce a first brainwave activity;
measuring the first brainwave activity of the user by a sensor;
comparing the first brainwave activity against a user profile to confirm the identity of the user;
displaying a second visual indicator, wherein the second visual indicator is flashing at a second frequency, different from the first frequency, to induce a second brainwave activity;
measuring the second brainwave activity of the user by the sensor;
comparing the second brainwave activity against the user profile to confirm the identity of the user, and
unlocking a security system level of a vehicle responsive to the user viewing the first visual indicator and the second visual indicator in combination, wherein
the first visual indicator and the second visual indicator are at separate locations, wherein the separate locations are located at a windshield, a rear view mirror, or an interior screen of the vehicle, and
the security system level permits a start-function of the vehicle.
