Preservation of Biometric Data Using Visual Cryptography
Preserving the biometric privacy such as digital biometric data (e.g. Face image) is very important now-a-days. In this paper, the authors explore the possibility of using visual cryptography technique. By using visual cryptography they can protect the user's important data from misuse. In the case of faces the original face image is dithered in to two host face image (known as sheet) that are stored in two separate database server such that the privacy the original image can be revealed only when both the images or sheets are available; at the same time not a single image can identify the original image.
