We present a novel idea for user authentication that we call brain-thoughts. The goal of a brain-thought system would be to extract as much useful data as possible from a user's brain signals upon "transmitting" a thought. In this paper we are proposing the idea of recording the users' thoughts in the form of the P300 Positive Voltage Spikes. Provided that these brain signals can be recorded and processed in an accurate, repeatable and reliable way using software such as Matlab, Simulink, BCI2000 etc, a brain-thought system might provide a quasi two-factor, changeable, authentication method resilient to shoulder-surfing and hacking techniques. In order to reinforce the security, we are proposing a concept of integrating our P300 system with another voluntarily generated brain waves pattern which is created when the subject closes his eyelids. In this paper, we shall also discuss the motivation and potential of brain-thought authentication, the status quo of BCI technology, and outline the design of what we believe to be a currently feasible brain-thought security system along with the implementation of Signal Processing using Matlab. We also briefly mention the need for general exploration and open debate regarding ethical considerations for such technologies.
