Fingerprint encryption is one of the most active research domains in biometrics recognition. However

fingerprints are human inherent characteristics

which are associated with one person permanently and cannot be changed. Once one fingerprint template is compromised

it is permanent. In order to avoid the loss of fingerprint templates

a set of irreversible transform functions

which are based on the Butterworth Low Pass Filter

are proposed. They transfer the original fingerprint templates to cancelable fingerprint templates. Those cancelable templates

stored in different recognition system

are different and irreversible

which can overcome the security limitations caused by the invariance and openness of the fingerprint templates. Experiments regarding matching precision

irreversibility and transform efficiency show that this scheme has high performance on authentication

security and computation.
