1. An apparatus for representing biometrics, comprising:

  • a biometric feature extractor for extracting features corresponding to a biometric depicted in an image, for defining at least one set of at least one geometric shape by at least some of the features, each of the at least one geometric shape having at least one geometric feature that is invariant with respect to a first set of transforms applied to at least a portion of the image; and

    a transformer for applying the first set of transforms to the at least a portion of the image to obtain at least one feature representation that includes at least one of the at least one geometric feature, and for applying a second set of transforms to the at least one feature representation to obtain at least one transformed feature representation.
