Claim One:
1. An apparatus comprising circuitry configured to: receive a plurality of images, wherein each of the plurality of images includes at least one iris; extract, from each of the plurality of images, the at least one iris image included in the image; receive a claimed identity iris image, wherein the claimed identity iris image corresponds to an identity to be authenticated based on the extracted iris images; normalize the extracted iris images and the claimed identity iris image; filter, in a first filtration process, the normalized extracted iris images to select a subset of the normalized extracted iris images, wherein the subset of the normalized extracted iris images are selected based on a similarity measurement between each of the normalized extracted iris images relative to the normalized claimed identity iris image; divide the normalized claimed identity iris image and each image of the subset of the normalized extracted iris images into a plurality of sub-images, wherein each of the plurality of sub-images is assigned a sub-image position indicating an ordered position of the sub-image within the sub-image's corresponding divided image; filter, as a second filtration process, the sub-images in a same sub-image position across all the sub-image positions corresponding to the normalized extracted iris images to select the sub-image having a closest similarity measurement relative to a sub-image of the normalized claimed identity image that is in a corresponding sub-image position to the selected sub-image; and generate a composite iris image by fusing the sub-images selected in the second filtration process.
