Abstract

Abstract: The security of Fuzzy Vault algorithm depends on the fingerprint template and the locking algorithm. By using the functions with variable parameters to transform the original values of fingerprint characteristics, a random value of fingerprint characteristic was generated. Also the multi-fuzzy vaults were formed by the key separation which allows more users to manage the fuzzy vaults together. Thus, the revocability of the fingerprint template was achieved and then the security of the original algorithm was improved.

Key words: variable parameters, revocability, key separation, muti-fuzzy vault, fingerprint
