Realization of correlation attack against the fuzzy vault scheme

摘要: User privacy and template security are major concerns in the use of biometric systems. These serious based on fact that once compromised, traits can not be canceled or reissued. The Fuzzy Vault scheme has emerged as a promising method to alleviate problem. is binding with secret key scrambling it large amount redundant data, such computationally infeasible extract without possession trait. It was recently claimed susceptible correlation attacks which assume availability two fuzzy vaults created using same data (e.g. impressions fingerprint) suggests correlating them would reveal hidden inside. In this work, we implemented vault fingerprints performed against database 400 (200 matching pairs). Given vaults, could successfully unlock 59% within short time. Furthermore, possible link an unknown list containing its pair, for 41% all vaults. results prove claim additional measures indeed vulnerable attacks.
