Systems and methods for discerning eye signals and continuous biometric identification

摘要

Apparatus, systems, and methods are provided for substantially continuous biometric identification (CBID) of an individual using eye signals in real time. The apparatus is included within a wearable computing device with identification of the device wearer based on iris recognition within one or more cameras directed at one or both eyes, and/or other physiological, anatomical and/or behavioral measures. Verification of device user identity can be used to enable or disable the display of secure information. Identity verification can also be included within information that is transmitted from the device in order to determine appropriate security measures by remote processing units. The apparatus may be incorporated within wearable computing that performs other functions including vision correction, head-mounted display, viewing the surrounding environment using scene camera(s), recording audio data via a microphone, and/or other sensing equipment.

主权项

1. A method for providing substantially continuous biometric identification of a user, comprising:
providing a headgear comprising a plurality of cameras oriented towards an eye of the user from different angles; analyzing one or more images from the cameras to identify an iris of the eye; selecting images from multiple cameras from the plurality of cameras providing desired views of the iris; creating a composite irisCode from the selected images; identifying the user based at least in part on the composite irisCode; and authorizing the user to perform one or more actions upon confirming the user's identity, wherein the multiple cameras are selected because a large enough portion of the iris is identifiable from the images to satisfy a minimum stringency threshold needed to identify the user, and wherein the selected images provide images of the iris from multiple angles, and wherein creating the composite irisCode comprises selecting portions of the iris from the selected images and combining the portions of the iris into a composite image of the iris, the method further comprising, after authorizing the user to perform one or more actions:
a) analyzing another set of images from the multiple cameras to identify features of the iris; andb) confirming the identity of the user based at least in part on the features of the iris from the another set of images, wherein steps a) and b) are repeated when a predetermined action is selected by the user that requires confirmation of identity before performing the predetermined action.
