Systems and Methods for Biometrically Authenticating a User Using Authentication Data and Liveness Data

Abstract

Systems and methods for biometrically authenticating a user are disclosed. In one implementation, a biometric authentication system may include a finger scanner for capturing biometric data from a plurality of sections of a finger of a user. The finger may include a distal section, a medial section, and a proximal section. The biometric authentication system may further include one or more processors configured to cause the finger scanner to capture the biometric data from the plurality of sections of the finger of the user. The biometric data may include authentication data and liveness data. The processors may be further configured to access registered authentication data associated with the user, determine whether the captured authentication data matches the authentication biometric data, and determining, using the captured liveness data, whether the finger is a live finger. Additionally, the processors may be configured to authenticate the user after the captured authentication data is determined to match the registered authentication data and after the finger is determined to be a live finger.

 access registered authentication data associated with the user; 
 determine whether the captured authentication data matches the registered authentication biometric data; 
 determine, using the captured liveness data, whether the finger is a live finger; and 
 authenticate the user after the captured authentication data is determined to match the registered authentication data and after the finger is determined to be a live finger.

         8 . A method for biometrically authenticating a user, the method comprising:
 capturing biometric data from a plurality of sections of a finger of a user, the finger including a distal section, a medial section, and a proximal section, and the biometric data including authentication data and liveness data;   accessing registered authentication data associated with the user;   determining whether the captured authentication data matches the registered authentication biometric data;   determining, using the captured liveness data, whether the finger is a live finger; and   authenticating the user after the captured authentication data is determined to match the registered authentication data and after the finger is determined to be a live finger.   
     
     
         9 . The method of  claim 8 , wherein the authentication data includes front-side fingerprints from the plurality of sections of the finger. 
     
     
         10 . The method of  claim 8 , wherein the method is performed by one of: automatic teller machine (ATM), point-of-service (POS) terminal, and a portable electronic device. 
     
     
         11 . The method of  claim 8 , wherein the authentication data includes at least one of: vein pattern of the finger and bone structure of the finger. 
     
     
         12 . The method of  claim 8 , wherein the liveness data includes data indicative of at least one of: blood flow in the finger, temperature of the finger, heart rate, and pulse. 
     
     
         13 . The method of  claim 8 , wherein the liveness data includes data indicative of at least one of: boundary shapes, discoloration, pore distribution, and ridge sharpness of the finger. 
     
     
         14 . The method of  claim 8 , wherein the biometric data is captured from the distal section, the medial section, and the proximal section of the finger. 
     
     
         15 . A non-transitory computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method for biometrically authenticating a user, the method comprising:
 capturing biometric data from a plurality of sections of a finger of a user, the finger including a distal section, a medial section, and a proximal section, and the biometric data including authentication data and liveness data;   accessing registered authentication data associated with the user;   determining whether the captured authentication data matches the registered authentication biometric data;   determining, using the captured liveness data, whether the finger is a live finger; and   authenticating the user after the captured authentication data is determined to match the registered authentication data and after the finger is determined to be a live finger.   
     
     
         16 . The non-transitory computer-readable storage medium of  claim 15 , wherein the authentication data includes front-side fingerprints from the plurality of sections of the finger.
