Method of and system for enrolling and matching biometric data
First Claim
1. A method comprising:
- collecting a set of biometric object image data for a biometric object image from a biometric object imaging sensor during an initial enrollment window;
storing the biometric object image data in a memory as a stored enrollment template for further comparison to find a match with subsequently imaged biometric object image data;
collecting a subsequent set of biometric object image data for a biometric object image from the biometric object imaging sensor during a limited enrollment window separate from the initial enrollment window and opened after the initial enrollment window ends;
updating the stored enrollment template;
determining if the limited enrollment window remains open; and
repeating the collecting of a subsequent set of biometric object image data step and the updating step if the limited enrollment window remains open,wherein the determining if the limited enrollment window remains open comprises determining the existence of one of a stability indicator and an instability indicator, andwherein the instability indicator comprises at least one of an amount of biometric image data being added to and an amount of biometric image data being removed from the stored enrollment template exceeding a selected threshold for a selected number of updates of the stored enrollment template.

Abstract
A system and method is disclosed for comparing biometric image data to a stored enrollment template that may comprise collecting a set of biometric image data for a biometric object image from a biometric object imaging sensor; storing the biometric object image data in a memory as an enrollment template for further comparison to find a match with subsequently imaged biometric object image data; collecting a subsequent set of biometric image data for a biometric object image from the biometric object imaging sensor; updating the enrollment template; determining if a limited enrollment window remains open; and repeating the collecting of a subsequent set of biometric data step if the enrollment window remains open. Determining if the enrollment window remains open may be by determining the existence of one of a stability indicator and an instability indicator.
