Patent ID: 8908929

Claim:
A method comprising: transforming a first collection of biometrics and a second collection of biometrics with cancelable non-invertible biometric transforms from a collection of cancelable non-invertible biometric transforms, wherein the first collection of biometrics includes biometric information identifying individuals associated with the biometrics of the first collection, and wherein the first collection of biometrics is stored on a first server and identity information identifying the individuals associated with the biometrics is stored on a separate second server, said transforming comprises: for each biometric in the first collection, randomly selecting a cancelable non-invertible biometric transform from said collection of cancelable non-invertible biometric transforms and applying the selected cancelable non-invertible biometric transform to the biometric; and, for each biometric in the second collection, applying each cancelable non-invertible biometric transform from said collection of cancelable non-invertible biometric transforms to the biometric separately to create a collection of transformed biometrics for each biometric in the second collection; comparing the transformed biometrics from the first collection with the transformed biometrics from the second collection; and if a match is found, recording information identifying the match for determining the identity of the individual corresponding to the match based on the identity information stored on the second server.
