Abstract: A multimodal biometric identification system captures and processes images of both the iris and the retina for biometric identification. Another multimodal ocular system captures and processes images of the iris and/or the from both eyes of a subject. Biometrics based on data provided by these systems are more accurate and robust than using biometrics that include data from only the iris or only the retina from a single eye. An exemplary embodiment emits photons to the iris and the retina of both eyes, an iris image sensor that captures an image of the iris when the iris reflects the emitted light, a retina image sensor that captures an image of the retina when the retina reflects the emitted light, and a controller that controls the iris and the retina illumination sources, where the captured image of the iris and the captured image of the retina contain biometric data.

Abstract: Retinal blood vessels are detected for biometric identification by: receiving at least one image with retinal data; detecting an area in the image corresponding to a spatial variation in the image; and determining a blood vessel pattern relative in the area. The spatial variation may be determined according to a spatial intensity gradient. The area corresponding to the spatial variation may be defined by a fitted shape. A specific embodiment determines a structural measurement, such as a structural center of mass, in the area, and the blood vessel pattern is determined relative to the structural measurement. The blood vessel pattern may be determined by identifying blood vessel cross sections within the area and linking the blood vessel cross sections to determine blood vessels. Furthermore, each of the blood vessel cross sections may be represented by an N-vector determined by a N-parameter non-linear fitting function or a linear function combination.

Abstract: A method and system captures a sequence of images of a biometric wherein the images include a common reference. The system aligns the images represented by the image data with respect to the common reference. Thereafter, the system analyzes an attribute of the biometric represented in the sequence of images to determine whether the attribute changes in the sequence of images in accordance with a living source.

Abstract: A method and system capture an image of the interior of the eye, for example the retina and determine whether the captured image is sufficient to provide data for identifying an individual or animal before attempting to generate the identification data. If the captured image is not sufficient, the method and system automatically capture another image of the interior of the eye.

Abstract: A method and system generates correlated biometric information by capturing an image of a retinal vessel pattern and simultaneously capturing an image of an iris minutia pattern. Retinal biometric data and iris biometric data are generated from the images. The retinal biometric data and the iris biometric data are then combined or linked to maintain the correlation between the two biometrics.

Abstract: The method of the present invention includes the analysis of data representing a bit mapped image of an area of an individual's retina that includes the optic disk where the data for each pixel of the image represents the intensity of the pixel. The method of the present invention locates the optic disk in the image and generates a unique and consistent signal pattern for identifying an individual from pixel data having a predetermined relationship to the individual's optic disk. The generated signal pattern is then used to verify the identity of the individual.
