Visual Cryptography for Providing Privacy to Biometric data

Abstract

Biometric authentication is consider as best authentication than the other, because it uses unique physiological characteristics such as face images , palm images ,iris code. It is important to keep biometric data that generated at the time of enrollment .Using visual cryptography it is easy to enhance the privacy of biometric data. A private face image is to hide into two host images and convert them into gray scale image and encrypt it and generate sheets that stored on database server. In GEVCS Authentication only done when original image and gray scale sheet and other sheets are available. So visual cryptography provides better privacy to biometric data. This system is used for any images.
