PROCESS OF FINGERPRINT AUTHENTICATION USING CANCELABLE BIOHASHED TEMPLATE.

Early bird Template protection using cancelable biometrics prevents data loss and hacking stored templates, by providing considerable privacy and security. Hashing and salting techniques are used to build resilient systems. Salted password method is employed to protect passwords against different types of attacks namely brute-force attack, dictionary attack, rainbow table attacks. Salting claims that random data can be added to input of hash function to ensure unique output. Hashing are speed bumps in an attacker's road to breach user's data. Research proposes a contemporary two factor authenticator called Biohashing. Biohashing procedure is implemented by recapitualted inner product over a pseudo random number generator key, as well as fingerprint features that are a network of minutiae. Cancelable template authentication used in fingerprint-based sales counter accelerates payment process. Fingerhash is code produced after applying biohashing on fingerprint. Fingerhash is a binary string procured by choosing individual bit of sign depending on a preset threshold. Experiment is carried using benchmark FVC 2002 DB1 dataset. Authentication accuracy is found to be nearly 97%. Results compared with state-of-art approaches finds promising. [ABSTRACT FROM AUTHOR]
