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.

Claims

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.

2. The apparatus of claim 1 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 parameterized non-invertible transform function.

3. The apparatus of claim 1 wherein the first biometric is voice information and the apparatus includes a sensor for obtaining voice information.

4. a method for securing biometric data using multiple biometrics comprising the step of:

a) Utilizing a program within a computer for parameterizing a non-invertible transform function using at least one biometric; and

b) utilizing a program within the computer for converting an additional biometric to an irreversibly altered biometric using the parameterized non-invertible transform function from step a.

5. The method of claim 4 wherein a plurality of additional biometrics are used to parameterize the non-invertible transform function.

6. The method of claim 4 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.

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