Abstract: The invention provides methods, systems and computer program products for secure biometric image processing. The invention involves acquiring a first image of a first field of view corresponding to a biometric camera. A first set of image information defining the first image is received at a processor implemented first high security operating environment, which first set of image information includes a second sub-set of image information relevant for biometric feature extraction or comparison. A second image of the first field of view corresponding to the biometric camera is rendered on a display, which second image is defined by a third set of image information such that the third set of information excludes the second sub-set of image information.

Abstract: The invention relates to technologies for eye based biometric authentication. The invention provides methods, apparatuses and computer programs for initiating an action based on characteristics of acquired biometric information. In an embodiment, the invention comprises (i) receiving at least one image comprising an image of at least part of an eye, (ii) determining whether the at least part of an eye has birefringent characteristics, and (iii) initiating a predefined action responsive to (a) the at least part of an eye exhibiting birefringent characteristics that are inconsistent with a predefined set of birefringent characteristics or (b) a determined lack of birefringent characteristics typical of a real eye, wherein the predefined action comprises any one or more of denying biometric enrollment, denying biometric authentication, denying access to a resource, denying a request for unlocking of a resource, or transmitting or recording information identifying a spoof.

Abstract: The invention provides methods, systems and computer program products for spoof detection in iris based biometric recognition. In an embodiment, the invention comprises (i) obtaining a first image of an iris at an imaging apparatus configured to a first exposure setting (ii) obtaining a second image of the iris at the imaging apparatus configured to a second exposure setting (iii) comparing incidence of reflection patterns within the first and second iris images and (iv) determining authenticity of the imaged iris based on a result of comparing the incidence of reflection patterns within the first and second iris images.

Abstract: The invention provides apparatuses, methods and computer program products for obtaining and processing images of one or more features of a subject's eye for biometric recognition. The invention comprises receiving a first image of a first image region within a field of view of an imaging apparatus and receiving a second image of a second image region within the field of view of the imaging apparatus. Thereafter it is determined whether image information extracted from the first image matches stored iris information corresponding to at least one iris. Responsive to the first determination rendering a non-match decision, performing a second determination comprising determining whether image information extracted from the second image matches the stored iris information.

Abstract: The invention relates to image based biometric recognition. In one aspect, the invention includes: performing a first biometric determination based on a first image by comparing information extracted from the first image against stored biometric information; performing a second biometric determination based on a second image by comparing information extracted from the second image against stored biometric information; combining outputs of the first and second biometric determinations; and, rendering a match decision or a non-match decision based on the combining of outputs. The first image may be an image of a field of view of an imaging apparatus under illumination from a first illumination source located at a first position relative to the field of view. The second image may be an image of the field of view under illumination from a second illumination source located at a second position relative to the field of view.
