Abstract: Methods and apparatus for illuminating a biometric aspect, such as periocular region features or iris features, with multiple illumination configurations to create multiple illumination channels for computer analysis are disclosed. Multiple illumination channels may be used for quality assurance by comparing the actual illumination channel property of a given image to the illumination channel that was activated for image capture. Images captured at the multiple illumination channels can also be used in biometric authentication by providing additional information for comparison to a stored template generated from images taken at multiple illumination channels during enrollment. Biometric authentication using a quality assurance process may be resistant to attempts to bypass biometric authentication.

Abstract: Methods for performing user authentication based on a multi-representation eye model for devices such as head-mounted display devices are disclosed. The multi-representation eye model may be generated and updated based on feature representations of an identified eye. The user authentication process may be initiated by causing an image to be captured of a current eye under a first set of conditions that may then be transformed into a current feature representation. The current feature representation may be applied to the multi-representation eye model to determine whether the current eye is a match for the identified eye.
