A Key Sharing Fuzzy Vault Scheme
Based on the classical fuzzy vault and the Diffie-Hellman key exchange scheme, a key sharing fuzzy vault scheme is proposed. In this fuzzy vault scheme, the two users cooperatively build their shared fuzzy vault with a shared key hidden in it using their own biometric features, and they can respectively use their biometric features to unlock the fuzzy vault to get their shared key without running the risk of disclosure of their biometric features later. The security of our scheme is based on the security of the classical fuzzy vault scheme and and the discrete logarithm problem in a given finite group.
