1. An apparatus for converting a first biometric to an irreversibly altered biometric comprising a computer containing a program for calculating the irreversibly altered biometric by: a) Utilizing the program within a computer for parameterizing a non-invertible transform function using at least one biometric; and b) Utilizing the program within the computer for converting an additional biometric to an irreversibly altered biometric using the parameterized non-invertible transform function from step a.
