Tongue Scanning as a Biometric Tool for Improvising the Security in Identification

Biometrics refers to a real-time identification system that is used in the identification of a person using a specific physical or behavioral characteristic which is compared with a library of characteristics of many other people.This is done using a biometric scanning device (tongue-print scan) which captures the user’s biometric data such as the tongue-print scan and converts it into a digital information that the computer interprets and verifies.Many models in biometric authentication system have come into existence such as finger print scan, iris scan, digital signature, voice recognization. These methods are using widely, even though these methods using widely they posses some demerits. This paper will discuss about the various biometric techniques and mention that “Tongue Scanning ” and how it overcomes the problems in existing techniques. keywords: tongue-print; biometric; Histogram; pattern recognition system; Tongue code; Biometrics authentication system
