Problems solved by technology

However, fingerprint identification systems suffer from the fact that users routinely leave fingerprints on various objects—and those fingerprints can be “lifted” and reproduced to circumvent fingerprint identification systems.
Also, face and voice recognition systems may not be sufficiently accurate and can often be circumvented with relative ease.
Such biometric camera systems face a number of challenges during their operation, including 1) ambient illumination (e.g. be able to op

Abstract

Exemplary embodiments for a biometric camera system for a mobile device, comprise: a near infrared (NIR) light source on the mobile device that flashes a user of the mobile device with near infrared light during image capture; a biometric camera located on the mobile device offset from the NIR light source, the biometric camera comprising: an extended depth of field (EDOF) imaging lens; a bandpass filter located adjacent to the EDOF imaging lens to reject ambient light during image capture; and an imaging sensor located adjacent the bandpass filter that converts an optical image of an object into an electronic signal for image processing; and a processor configured to receive video images of an iris of a user from the image sensor, and attempt to match the video images of the iris with previously registered images stored in an iris database, wherein if a match is found, the user is authenticated.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of Provisional Application Ser. No. 61 / 884,778, filed Sep. 30, 2013; Provisional Application Ser. No. 61 / 885,291, filed Oct. 1, 2013; and Provisional Application Ser. No. 61 / 913,620, filed Dec. 9, 2013, each assigned to the assignee of the present application, and incorporated herein by reference.BACKGROUND[0002]Mobile devices such as laptops—and most recently smartphones—have included biometric devices with the purpose of user identification. The biometric devices for example include fingerprint scanners, iris scanners and camera systems capable of face and / or voice recognition. However, fingerprint identification systems suffer from the fact that users routinely leave fingerprints on various objects—and those fingerprints can be “lifted” and reproduced to circumvent fingerprint identification systems. Also, face and voice recognition systems may not be sufficiently accurate and can often be circumvent...
