A biometric authentication system operates by acquiring raw biometric data from a subject e.g., fingerprint and iris images. This original raw data is stored in the central database. Preserving the privacy of this digital biometric data has become very important. Visual cryptography can be applied for securing this information. The proposed paper preserves the privacy fingerprint and iris based authentication using Inverted Share image Visual Cryptography (ISVC). In ISVC, the authors invert one share image and stack it with other share image to obtain the extra confidential data that can used for authentication.
