Cancelable fingerprint fuzzy vault scheme

Fuzzy vault is a cryptographic framework that binds the biometric template with a cryptographic key.However,attackers can easily compromise them if they steel more than two vaults of a legal user by cross matching.A new scheme named cancelable fuzzy vault was proposed to overcome this shortcoming,which generated different vaults from different cancelable templates instead of the origin template.In our scheme,a mixture of butterworth low filter was taken as the transform function which generated a cancelable template.In addition,users' passwords were adopted to encrypt the vaults to improve their security.
