Abstract
Method and apparatus for securing biometric data using multiple biometrics. The method includes the steps of: a) converting a first biometric to an irreversibly altered biometric using a parameterized transform function and b) prior to said conversion parameterizing a non-invertible transform function using at least one additional biometric. The apparatus is an apparatus for converting a first biometric to an irreversibly altered biometric using a parameterized non-invertible transform function comprising a computer containing a program for calculating the irreversibly altered biometric based upon input of a first biometric into the parameterized non-invertible transform function.
Claims7
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.
