A survey of emerging biometric modalities

Abstract Biometric recognition is the task of identifying an individual on the basis of his/her physiological or behavioral traits. Necessity of developing fool proof security systems has provided biometric research much needed impetus. Over the last three decades there has been a lot of work done on development of systems based on fingerprint, face, iris, voice etc., but in the recent past some new biometric measures have emerged which have shown prospect of enhancing the performance of the traditional biometrics by fusing these new biometric modalities with established ones. Some of these biometric measures have shown tremendous potential in forensic applications. In this paper a review of two of these emerging biometric modalities is presented.
