An Evaluation Of Fingerprint Security Using Noninvertible Biohash
N. Radha, S. Karthikeyan · International Journal of Network Security & Its Applications · 2011
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 re-alignment 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.
