Dual Fingerprints Fusion for Cryptographic Key Generation

Secured data transfer is a critical issue through open networks due to attackers and intruders. This paper presents a new cryptographic key generation algorithm from dual fingerprint biometric template; the suggested approach has simplified the generation of cryptographic keys and reduces the complexity of traditional cryptosystem. . Fingerprints are permanent throughout person’s lifespan. Keys are generated from the fingerprint template for encrypting and decrypting the content of the user. This method can be implemented in MATLAB and it generates different size cryptographic keys, with limited amount of time complexity and space complexity. This is appropriate for all real time applications that establish secured information exchange between the users. Proposed method is evaluated using publicly available FVC2002 database and achieves better result.
