An Evaluation Of Fingerprint Security Using Noninvertible Biohash

Abstract

Biometric analysis for identifying verification is becoming a widespread reality. It is a very challenging and tedious task to develop a biometric template protection scheme which is anonymous, revocable and noninvertible while maintaining decent performance. Cancellable biometrics is one of the best methods used to resolve this problem. In this paper, a new method called as BioHashing which follows the technique of cancellable biometrics in the fingerprint domain is proposed. This proposed method does not require the realignment of fingerprints as all the minutiae are translated into a pre-defined two dimensional space based on a reference minutia. After that, the proposed Biohashing method is used to enforce the one-way property (non-invertibility) of the biometric template. The proposed approach is very much resistant to minor translation error and rotation distortion. An Equal Error Rates (EER) of less than 1% is achieved in this approach and performance of the approach is also significant.
