Visual cryptography improvises the security of tongue as a biometric in banking system

The importance of utilizing biometrics to establish personal authenticity and to detect imposters is growing in the present scenario of global security concern. Also the Development of a biometric system for personal identification, which fulfills the requirement for access control of secured areas and other applications like identity validation for social welfare, crime detection, ATM access, computer security, etc. is felt to be the need of the day. The human tongue promises to deliver a level of uniqueness to identification applications that other biometrics cannot match in context of that it is well protected in 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. The 3D scanning of human tongue is an important tool to acquire accurate shape and texture information of tongue for recognition purposes. As we use biometrics mainly for security purpose so preserving the privacy of digital biometric data (e.g. tongue prints) stored in a central database has become of paramount importance, for this we are using visual cryptography while using it in biometric authentication system. This paper proposes the tongue biometric with visual cryptography technique to increase the efficiency of the proposed tongue biometric authentication system (banking system) using 3D database.
