ABSTRACT Combination of Cryptography and Biometrics to provide high security. Biometric templates play the main role in authenticating the individual identification. Biometric traits like fingerprint, retina and iris have certain merits when compared to other biometrics. Iris provides high speed of comparison and it is well suited for one-to-many identification. The iris templates are more stable or have more template longevity. Iris templates need not be updated frequently, a single enrollment can last a lifetime .This paper explores the biometric based authentication is blended with cryptography output called fuzzy vault which provides a high security. The proposed algorithm aims at generating a secret encryption key from iris textures and data units for locking and unlocking the vault. The algorithm has two phases: The first to extract binary key from iris textures, and the second to generate fuzzy vault by using Lagrange interpolating polynomial projections
