A low-cost Multi-Fingervein Verification System

摘要

Fingervein based biometric verification systems are widely used in various access control applications due to their accuracy and reliability. However, almost all existing fingervein systems scan only one finger at a time and this may not be a reliable solution for more secured applications demanding higher accuracy in verification and reliability. In this work, we propose a new multi-fingervein capture system that can simultaneously capture three different fingers in a single capture instance. The developed fingervein sensor is validated for operational purposes through images captured from 20 unique identities(subjects) with 600 fingervein images. The suitability of captured images for biometric applications is vetted through the use of four different state-of-the-art verification algorithms. The results are benchmarked and compared using individual fingervein data and in addition the employability of score level fusion is presented to improve the performance. The reported results in this article support the anticipated increase in performance of the multi-fingervein verification.
