Abstract

The tongue is a unique organ in that it can be stuck out of mouth for inspection, and yet it is otherwise well protected in the mouth and is difficult to forge. The tongue also presents both geometric shape information and physiological texture information which are potentially useful in identity verification applications. Furthermore, the act of physically reaching or thrusting out is a convincing proof for the liveness. Despite these obvious advantages for biometrics, little work has hitherto been done on this topic. In this paper, we introduce this novel biometric and present a verification framework based on the tongue-prints. The preliminary experimental results demonstrate the feasibility of the tongue biometrics.
