Fuzzy Biometric identity-based signature in the standard model
Using a biometric as an identity has the advantage that identities are unique if the underlying biometric is of a good quality,such as fingerprints,faces,irises,etc.However,biometric measurements are noisy and the existing identity-based systems cannot be used directly to construct this scheme.The error-tolerance property(Fuzzy) can be used to solve this problem.Based on the error-tolerance property,a new biometric identity based signature scheme is proposed.Our scheme is constructed in the standard model and achieves a strong security-full security.In addition,the security of our scheme is reduced to a generalized assumption-Computation Diffie-Hellman(CDH) assumption instead of other strong assumptions.
