An iris cryptosystem for information security

Abstract

Securing information is a key issue in the field of network security and cryptography is one of the most effective ways to enhance information security. Biometric cryptography is a technique using biometric features to encrypt the data, which can improve the security of the encrypted data and overcome the shortcomings of the traditional cryptography. This paper proposes a novel biometric cryptosystem based on the most accurate biometric feature - iris. In this system, a 256-dimension textural feature vector is extracted from the preprocessed iris image by using a set of 2-D Gabor filters. And then a modified fuzzy vault algorithm is employed to encrypt and decrypt the data. Experimental results demonstrate the feasibility of the proposed system.
