Forgotten Secret Recovering Scheme and Fuzzy Vault Scheme - Proposal of New Biometric-Scheme

摘要

In this paper, we revisit the Forgotten Secret Recovering Scheme for k users, referred to as FSRS(k) previously proposed by the present author. We show that FSRS(1) can be successfully applied to the various cryp-to-scheme including Fuzzy Vault Scheme (FVS), biometrics by taking advantage of the fact that Reed-Solomon code (RS code) is used in a form of systematic code. We finally present a new class of biometric scheme referred to as K-BS, based on FSRS(1).
