Finger Vein Biometric Algorithm

Synonym

Finger vein feature segmentation

Definition

Finger vein biometric algorithm is a series of software processes to authenticate a person by using biometric features extracted from his or her finger vein patterns. The algorithm is typically comprised of two major processes, namely, a finger vein feature extraction part and a matching algorithm part.

Introduction

Finger vein feature extraction, along with finger vein imaging technology, is a core technology in finger vein authentication. By applying this process, a simple raw finger vein image is converted into meaningful biometric data that can be used to identify a person. The finger vein feature extraction is executed in both the enrollment process and the authentication process of a finger vein biometric system. In the enrollment process, the extracted biometric data is used to create template data together with the associated personal information such as username or identification numbers. In the authentication process, the...
