Preserving the privacy of biometric data such as fingerprint images stored in central database has become paramount importance. This can be done possible using visual cryptography for biometric privacy such as fingerprint images. A private fingerprint image is dithered into two host images(known as sheets) that are stored in two separate database servers such that the private image can be revealed only when both sheets are simultaneously available; at the same time, the individual sheet images do not reveal the identity of the private image. The images are stored in database by applying encryption. The stored images are encrypted and while verification that images are decrypted. So the authors propose biometric privacy using visual cryptography with pixel sharing.
