Patent number: 10534969Abstract: The present disclosure describes systems and methods for imaging an iris for biometric recognition. An image sensor may be located a distance L from an iris, to acquire an image of the iris. The image may have a contrast amplitude comprising modulation of a signal level at the image sensor due to features of the iris being acquired, and a standard deviation of said signal level due to noise generated within the image sensor. An illumination source may provide infrared illumination during acquisition of the image. When L is set at a value of at least 30 centimeters, the illumination source can provide the infrared illumination to the iris at a first irradiance value, quantified in watts per centimeter-squared, such that the contrast amplitude is at a value above that of the standard deviation, and enables the acquired image to be used for biometric recognition.Type: GrantFiled: February 22, 2018Date of Patent: January 14, 2020Assignee: EYELOCK LLCInventor: George Herbert Needham Riddle

Patent number: 10372982Abstract: The methods and apparatus for repetitive iris recognition include an apparatus for repetitively imaging an iris. The apparatus comprises a housing defining a substantially planar outer surface, a first axis normal to the substantially planar outer surface, and a curved outer surface, opposite the substantially planar outer surface, defined by a curve rotated about the first axis. The apparatus further comprises an infrared sensor array, disposed within the housing, to acquire an infrared image of an iris via at least one first aperture in the substantially planar outer surface. The apparatus further comprises at least one infrared illuminator, disposed within the housing, to illuminate the iris during acquisition of the infrared image of the iris via at least one second aperture in the substantially planar outer surface.Type: GrantFiled: January 6, 2015Date of Patent: August 6, 2019Assignee: Eyelock LLCInventors: David McDonald, Daniel Sanchez, George Herbert Needham Riddle

Patent number: 10296791Abstract: The present disclosure is directed towards a compact, mobile apparatus for iris image acquisition, adapted to address effects of ocular dominance in the subject and to guide positioning of the subject's iris for the image acquisition. The apparatus may include a sensor for acquiring an iris image from a subject. A compact mirror may be oriented relative to a dominant eye of the subject, and sized to present an image of a single iris to the subject when the apparatus is positioned at a suitable distance for image acquisition. The mirror may assist the subject in positioning the iris for iris image acquisition. The mirror may be positioned between the sensor and the iris during iris image acquisition, and transmit a portion of light reflected off the iris to the sensor.Type: GrantFiled: April 6, 2018Date of Patent: May 21, 2019Assignee: EyeLock LLCInventors: Keith J. Hanna, Gary Alan Greene, David James Hirvonen, George Herbert Needham Riddle
