Intent Biometrics: An Enhanced Form of Multimodal Biometric Systems

Biometrics is a field in which very little progress has been made since it was first established. One of the major milestones in the field was the introduction of the multi-modal biometrics concept which uses a multi-factor authentication method. In this method, multiple factors are being authenticated as opposed to a single factor in the ´classic´ unimodal biometric systems. This paper proposes an extension to the multi-modal biometrics concept to check for individuals´ consent or intent to authenticate. It does that by checking certain physiological characteristics during authentication together with the classic biometric traits of fingerprints, iris etc. This additional physiological measurement will indicate whether the user authenticating is doing so without consent or whether the authentication is done with mal intentions.
