A Novel Approach for Regenerating a Secure and Reliable Password using Iris and Fingerprint

Abstract

Cryptography - biological authentications are mechanisms that attempt to identify users by combining unique features such as physical and behavioral characteristics. The old method which was based on passwords (e.g., public key, AES, etc.) can be easily discovered by attackers. In order to improve local security key, this paper presents a method that uses biological fingerprints and iris patterns to generate cryptographic keys. In this method, fingerprint and iris images are collected from the users and the security private key will be created by combining extracted patterns of iris and fingerprint and a hash function. The private key is used for cryptographic applications. Results showed that the model presented in this paper is more resistant against attacks compared with the patterns that are solely based on passwords.
