Systems and methods for performing fingerprint based user authentication using imagery captured using mobile devices

Abstract

Technologies are presented herein in support of a system and method for performing fingerprint recognition. Embodiments of the present invention concern a system and method for capturing a user's biometric features and generating an identifier characterizing the user's biometric features using a mobile device such as a smartphone. The biometric identifier is generated using imagery captured of a plurality of fingers of a user for the purposes of authenticating/identifying the user according to the captured biometrics and determining the user's liveness. The present disclosure also describes additional techniques for preventing erroneous authentication caused by spoofing. In some examples, the anti-spoofing techniques may include capturing one or more images of a user's fingers and analyzing the captured images for indications of liveness.

AI Technical Summary

Benefits of technology

[0014]According to a first aspect, a method for performing fingerprint recognition is provided. The method includes the step of capturing, by a mobile device having a camera, a storage medium, instructions stored on the storage medium, and a processor configured by executing the instructions, one or more images depicting a plurality of fingers of a subject. The method also includes detecting, using a finger detection algorithm a plurality of fingers depi

Problems solved by technology

As a biometric is a biological characteristic (such as a fingerprint, the geometry of a hand, retina pattern, iris texture, etc.) of an individual, biometric techniques can be used as an additional verification factor since biometrics are usually more difficult to obtain than other non-biometric credentials.

Moreover, missing, swapping, mixing, and illegal adoption of newborns is a global challenge and using automated biometric systems has been proposed to identify new borns based on their face, iris, fingerprint, footprint, and/or palmprint.

However, to the extent iris, face, finger, and voice identity assertion systems exist and provide the requisite level of accuracy, such systems require dedicated devices and applications and are not easily implemented on conventional smartphones, which have limited camera resolution and light emitting capabilities.

ster. A disadvantage of these systems is that the fingerprint sensor adds size weight and cost to the d

evice. Furthermore, for these reasons it is advantageous to minimize the size of the fingerprint sensor, and as such the fingerprint sensor typically captures only a portion of the fingerprint which reduces the effectiveness of the identifi

cation. The smaller the region of capture for the fingerprint sensor, the more cha
