Protection of biometric data is gaining importance because its uniqueness and digital watermarking techniques are used to protect the biometric data from either accidental or intentional attacks. Here introduces a novel secured authentication method using wavelet decomposition and visual cryptography to hide an iris image. In this report gives exhaustive study on a scheme in which iris image is secured by using a technique called Visual Cryptography (VC). In this technique, iris image is embedded in cover image and then using wavelet transform this output image is decomposed into four shares. These four shares are compressed at sender site.
