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 non-convertible transform function and b) prior to said conversion parameterizing a non-convertible 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-convertible 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-convertible transform function.

Claims

1. A method for securing biometric data using multiple biometrics comprising:

a) converting a first biometric to an irreversibly altered biometric using a parameterized non-convertible transform function;

b) prior to said conversion parameterizing a non-convertible transform function using at least one additional biometric.

2. The method of claim 1 wherein a plurality of additional biometrics are used to parameterize the non-convertible transform function.

3. The method of claim 1 wherein the first and additional biometrics are selected from the group consisting of facial characteristics;

fingerprints;

hand geometry;

capillary arrangement in the retina;

iris ring color;

signature;

vein arrangement;

voice characteristics; and

DNA structure.

4. The method of claim 1 wherein the conversion is accomplished by substituting digitized biometric parameters of the first biometric into the parameterized non-convertible transform function to obtain the irreversibly altered biometric.

5. The method of claim 1 where the first biometric is converted into the parameterized non-convertible transform function by a computer containing a program for calculating the irreversibly altered biometric based upon input of the first biometric.

6. An apparatus for converting a first biometric to an irreversibly altered biometric using a parameterized non-convertible 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-convertible transform function.

7. The apparatus of claim 6 wherein the apparatus includes a scanner for obtaining information for a first biometric selected from the group consisting of fingerprints, facial features, vein arrangement, capillary arrangement and color and a digitizer for digitizing such information for input into the parametized non-convertible transform function.

8. The apparatus of claim 6 wherein the first biometric is voice information and the apparatus includes a sensor for obtaining voice information.
