Visual Cryptography for Providing Privacy to Biometric Data

Abstract

It is important to keep privacy of biometric data that stored in a central database. using visual cryptography it is easy to enhance the privacy of biometric data such as face images, palm images, iris code. A private face image is dithered into two images and stored them on two different database server. When the both images combine together after that we find the private image. Visual Cryptography is a process of creating shares from an Image so that it would become unreadable for unauthenticated person. This paper implements visual cryptography for color images
