VC of IRIS Images for ATM Banking
It is of great importance over a past few years, the increasing concern to preserve the privacy of biometric data over personal information that is stored in computer systems. It mostly has increased interest in data security. For possible use in biometric identification and protection, in this paper it applies visual cryptography(VC) which is a perfectly secured method of maintaining image security. The basic concept of visual cryptography is to divide secret images in to random shares using key and decryption is performed by superimposing the shares using the similar key which is used at encryption side.
