Comprehensive brainwave authentication using emotional stimuli

In this paper we propose a new concept of authentication. Beyond deciding whether a user is entitled to the resources he claims, the authentication process provides information about the state of the user and his capacity to responsibly handle the resources he has the right to access. We chose emotions as credentials because aside from being inextricably linked to the user, their variation over time provides valuable metainformation about the user´s state and evolution. On a practical level, the first target of this type of authentication are disabled persons who could thus gain higher life quality by having access to online banking, education etc.
