Abstract
This paper describes the feasibility of enhancing existing biometrics technology with a spectroscopic method in order to prevent spoofing. It goes beyond the simple approach of an aliveness detection technique and proposes the implementation of verification of a person's unique `spectral signatures' or `factors' in addition to currently employed methodologies in a multi-factor manner to reduce the likelihood of an imposter getting authenticated. This paper also shows how to augment two widely used biometrics systems (fingerprint and iris recognition devices) with spectral biometrics capabilities in a practical manner and without creating much overhead or inconveniencing their users.
