Abstract
A biometric authentication system, including a database of digital images of biometrics of known people, a camera for capturing a digital image of a biometric of an unknown person, a two-dimensional gradient filter coupled with said database and said camera for deriving a spatial gradient of a digital image, and a match processor coupled with the two-dimensional gradient filter for processing two spatial gradients and determining the extent to which the unknown biometric corresponds with a known biometric. A method and a computer-readable storage medium are also described and claimed.

A biometric authentication system, comprising:
- a database of digital images of biometrics of known people;
- a camera for capturing a digital image of a biometric of an unknown person;
- a match processor for identifying a second planar graph of nodes within an image of a known biometric that corresponds to a first planar graph of nodes within the image of the known biometric;
- and
- a match detector coupled with said match processor for concluding whether or not the unknown biometric matches the known biometric, based on the extent to which edges in the second planar graph align with edges in the first planar graph.
A computer processor-based method for biometric authentication, comprising:
- capturing, by a computer, a digital image of a biometric of an unknown person;
- identifying, by the computer, a second planar graph of nodes within an image of a biometric of a known person that corresponds to a first planar graph of nodes within the image of the unknown biometric;
- and
- concluding, by the computer, whether or not the unknown biometric matches the known biometric, based on the extent to which edges in the second planar graph align with edges in the first planar graph.
