Patent ID: 8798331

Claim:
A method for biometric matching with iris data, comprising: acquiring, by a sensor, a sequence of images of an iris; combining at least two images from the sequence of images of the iris to define an acquired image and to identify specularities; selecting a portion of the acquired image, the portion selected having fewer specularities on the acquired image for matching against stored iris data corresponding to the selected portion; performing one or more transformations to the selected portion to generate a plurality of transformed images, the one or more transformations comprising at least one of: translation, rotation, resizing and removal of deformation; and determining if a transformed image from the plurality of transformed images matches the stored iris data, wherein: the sequence of images includes a first image and a second image, and combining the at least two images from the sequence of images includes subtracting the first image from the second image to identify a specularity.
