We consider the problem of generating a biometric image from two different traits. Specifically, we focus on
generating an IrisPrint that inherits its structure from a fingerprint image and an iris image. To facilitate this,
the continuous phase of the fingerprint image, characterizing its ridge flow, is first extracted. Next, a scheme is
developed to extract “minutiae” from an iris image. Finally, an IrisPrint, that resembles a fingerprint, is created
by mixing the ridge flow of the fingerprint with the iris minutiae. Preliminary experiments suggest that the new
biometric image (i.e., IrisPrint) (a) can potentially be used for authentication by an existing fingerprint matcher,
and (b) can potentially conceal and preserve the privacy of the original fingerprint and iris images.
