Biometric Imaging Devices and Associated Methods
First Claim
1. A system for authenticating a user through identification of at least one biometric feature, comprising:
- an active light source capable of emitting electromagnetic radiation having a peak emission wavelength at from about 700 nm to about 1200 nm, the active light source being positioned to emit the electromagnetic radiation to impinge on at least one biometric feature of the user;
an image sensor having infrared light-trapping pixels positioned relative to the active light source to receive and detect the electromagnetic radiation upon reflection from the at least one biometric feature of the user, the light trapping pixels having a structural configuration to facilitate multiple passes of infrared electromagnetic radiation therethrough;
a processing module functionally coupled to the image sensor and operable to generate an electronic representation of the at least one biometric feature of the user from detected electromagnetic radiation;
an authentication module functionally coupled to the processing module operable to receive and compare the electronic representation to an authenticated standard of the at least one biometric feature of the user to provide authentication of the user; and
an authentication indicator functionally coupled to the authentication module operable to provide notification that the user is authenticated.

Abstract
Systems, devices, and methods for authenticating an individual or user using biometric features is provided. In one aspect, for example, a system for authenticating a user through identification of at least one biometric feature can include an active light source capable of emitting electromagnetic radiation having a peak emission wavelength at from about 700 nm to about 1200 nm, where the active light source is positioned to emit the electromagnetic radiation to impinge on at least one biometric feature of the user, and an image sensor having infrared light-trapping pixels positioned relative to the active light source to receive and detect the electromagnetic radiation upon reflection from the at least one biometric feature of the user. The system can further include a processing module functionally coupled to the image sensor and operable to generate an electronic representation of the at least one biometric feature of the user from detected electromagnetic radiation, and an authentication module functionally coupled to the processing module that is operable to receive and compare the electronic representation to an authenticated standard of the at least one biometric feature of the user to provide authentication of the user.

34. A method of authorizing a user with an electronic device for using a secure resource, comprising:
-
delivering electromagnetic radiation from an active light source in the electronic device to impinge on the user such that the electromagnetic radiation reflects off of at least one biometric feature of the user, the electromagnetic radiation having a peak emission wavelength of from about 700 nm to about 1200 nm; detecting the reflected electromagnetic radiation at an image sensor positioned in the electronic device, wherein the image sensor includes infrared light-trapping pixels positioned relative to the active light source to receive and detect the electromagnetic radiation upon reflection from the at least one biometric feature of the user, the light trapping pixels having a structural configuration to facilitate multiple passes of infrared electromagnetic radiation therethrough; generating an electronic representation of the at least one biometric feature of the user from the reflected electromagnetic radiation; comparing the electronic representation to an authenticated standard of the at least one biometric feature of the user to authenticate the user as an authenticated user; and authorizing the authenticated user to use at least a portion of the secure resource. - View Dependent Claims (35, 36, 37, 38, 39)
