Application-specific key release scheme from Biometrics
Thian Song Ong, Andrew Beng Jin Teoh, David Chek Ling Ngo · 2008
This paper outlines a novel biometric key release scheme to bind application-specific key from biometric data such that the key can be retrieved effectively by using Discrete-Hashing and Reed Solomon Block Coding (RSB). We use fingerprint as a subject of study and our experiment shows that the proposed method could retrieve an error free key reliably from a legitimate fingerprint up to 99.8 % success rate with zero false acceptance and 0.12 % of false rejection. In addition, our analysis suggests that the scheme is feasible to use in practice. Keywords: Application-specific key, discrete-hashing, reed-solomon block coding 1
