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 rejec-tion. In addition, our analysis suggests that the scheme is feasible to use in practice.
