Abstract: Biometric cryptosystems has widespread applications in this era. Generally associated to a personal device for privacy protection, biometric references are stored in secured electronic devices such as smart cards, and systems are using cryptographic tools to communicate with the smart card and securely exchange biometric data. The biometrics used in this paper is fingerprint. In many areas, fingerprint recognition is used to improve the security and privacy. In this paper, we propose a novel system for protecting fingerprint privacy by combining two different fingerprints into a new identity called combined minutiae template, stored in both database and smart card. Smart cards are widely acknowledged as one of the most secure and reliable forms of electronic identification. Combining smart card technology with biometrics provides the means to create a positive binding of the smart card to the cardholder thereby enabling strong verification and authentication of the cardholder’s identity. Biometric cryptosystems combine cryptography and biometrics to benefit from the strengths of both fields. In such systems, while cryptography provides high and adjustable security levels, biometrics brings in non-repudiation and eliminates the need to remember a memorable password or passphrase etc. Fingerprint has been integrated in the RSA algorithm for biometric public/private key generation. Using RSA algorithm, we can generate a biometric based asymmetric keys from the biometric template of a user stored in the database. We grant authentication and using these keys we can encrypt/decrypt message. New approaches have endeavored towards merging biometrics with cryptography, so as to increase overall security of the system.
