Utilization of biometric data

Abstract

A method of capturing and storing a plurality of biometric data by a user on a device for a future authentication request is presented. The method includes receiving a first input from a user, through a user input mechanism of the device. The first input comprises a first portion of biometric data. The method also comprises receiving a second input from a user, through the user input mechanism. The second portion comprises a second portion of biometric data. The method also comprises storing the first and second inputs from the user in a biometric data memory portion of a memory of the mobile device. Each input is stored in the memory along with a time stamp assigned by a processor of the device. Each received input is stored such that, upon receiving an authentication request, each input is retrievable by the processor, from the memory based on a recency of the time stamp, such that the most recent input is retrieved first.

What is claimed is: 
     
         1 . A method of capturing and storing a plurality of biometric data by a user on a device for a future authentication request, the method comprising:
 receiving a first input from a user, through a user input mechanism of the device, wherein the first input comprises a first portion of biometric data;   receiving a second input from a user, through the user input mechanism, wherein the second portion comprises a second portion of biometric data;   storing the first and second inputs from the user in a biometric data memory portion of a memory of the mobile device, wherein each input is stored in the memory along with a time stamp assigned by a processor of the device, and wherein, each received input is stored such that, upon receiving an authentication request, each input is retrievable by the processor, from the memory based on a recency of the time stamp, such that the most recent input is retrieved first.   
     
     
         2 . The method of  claim 1 , and further comprising:
 comparing, prior to entering each input into the memory, the first portion of biometric data to the second portion of biometric data and, upon finding a partial match between the first and second portions of biometric data, storing the second input in the biometric data memory portion.   
     
     
         3 . The method of  claim 1 , wherein the time stamp is a relative time stamp, referring to an elapsed time between a capture and the future authentication request. 
     
     
         4 . The method of  claim 1 , wherein the time stamp is an absolute time stamp. 
     
     
         5 . The method of  claim 1 , wherein the biometric data memory portion of the device is a secured memory. 
     
     
         6 . The method of  claim 1 , wherein the biometric data memory portion is periodically purged of all biometric data. 
     
     
         7 . The method of  claim 1 , wherein the biometric data memory portion is purged when an on/off status of the device changes. 
     
     
         8 . The method of  claim 1 , wherein the biometric data memory portion is purged based on a detected trigger. 
     
     
         9 . A mobile device with a touchscreen configured to provide automatic biometric authentication, the device comprising:
 a fingerprint sensor built into the touchscreen, the fingerprint sensor configured to passively capture a plurality of fingerprint portions associated with a user of the mobile device;   a memory configured to store the captured plurality of fingerprint portions, wherein each captured plurality of print is stored with a time stamp; and   a processor configured to, upon receiving an authentication request from a source, automatically assemble a set of fingerprint portions sufficient to meet a security requirement associated with the authentication request.   
     
     
         10 . The mobile device of  claim 9 , wherein the memory also comprises an enrollment template, and wherein, before storage, each of the captured plurality of fingerprint portions is compared to the enrollment template, and a matching fingerprint portion is stored. 
     
     
         11 . The mobile device of  claim 9 , wherein the security requirement comprises a number of fingerprint portions with an overlap portions captured within a secured time period. 
     
     
         12 . The mobile device of  claim 9 , wherein the plurality of fingerprint portions comprises a combination of captured touch fingerprint portions and captured swipe fingerprint portions.
