Biometric Encrypted Secure Storage

Abstract

In modern world, securing information is a very important task. Cryptographic systems are integral part of any system. Security requirements demand that these system be operated with very large secret keys [1]. Since it is very difficult to remember very large keys, Biometric System are used for authenticated access. In the traditional Biometric System users are identified on the basis of stored Biometric image or Biometric template of a person. Biometric authentication system have many weak points, one of them is theft of Biometric template database [2]. In this case user can’t use stolen Biometric again due to high risk of misuse. Biometric encryption is a security scheme that combines the Biometric template with a strong cryptographic scheme to provide better security by storing a key instead of Biometric template [2]. In this project a system has been designed for secure storage of data, by providing authentication by fingerprint biometric and for the security of biometric template, biometric encryption is used where a random key is generated, which is unknown to everyone. System generates another key from random key and biometric template using biometric encryption algorithm, generated key is converted into barcode and provided to user for access. System deletes biometric template form memory and stores random key as match key in database. During authentication User provides barcode and fingerprint, from them a key is generated which is matched with the stored key. If match found then authentication granted.
