dc.description.abstractJust as biometric authentication has replaced conventional authentication methods to improve convenience and security, fuzzy signatures (FS), a technique that replaces the signing key of a digital signature with biometric information, has been studied. This paper proposes biometricindependent fuzzy signature (BIFS), a novel FS primitive that enables biometric-independent verification, which is inherently unsolvable with conventional FS. To circumvent that problem, BIFS generates signatures through a two-party protocol using biometric information and helper keys. We also propose a construction of BIFS that can easily replace existing signature services because the signature and verification keys are in the same form as those of digital signatures.en
