TONGUE PRINTS AS A BIOMETRIC AUTHENTICATION TOOL

Abstract

Identity fraud is a serious threat to society. Efficient identification systems are at
urgent need to society. Among various personal identification biometric methods tongue print is
a new biometric authentication tool that is unique and cannot be easily forged because no two
tongue prints are similar. The tongue is a unique organ as it can be displayed for inspection and
palpation, in this act offering a proof of life, and yet it is otherwise well protected in the mouth
and is difficult to forge. By means of its shape and texture, its aspects and colour analysed in a
particular moment, this organ is helpful to identify from one individual to another. The tongue
also presents both geometric shape information and physiological texture information which are
potentially useful in identity verification applications. The present paper provides literature
review for tongue marks in personal identification.
