ABSTRACT
Biometrics is a technology that enables an individual person to be identified based on human physiological and behavioral characteristics. Among biometrics technologies, face recognition has been widely used because of its advantages in terms of convenience and non-contact operation. However, its performance is affected by factors such as variation in the illumination, facial expression, and head pose. Therefore, fingerprint and iris recognitions are preferred alternatives. However, the performance of the former can be adversely affected by the skin condition, including scarring and dryness. In addition, the latter has the disadvantages of high cost, large system size, and inconvenience to the user, who has to align their eyes with the iris camera. In an attempt to overcome these problems, finger-vein recognition has been vigorously researched, but an analysis of its accuracies according to various factors has not received much attention. Therefore, we propose a nonintrusive finger-vein recognition system using a near infrared (NIR) image sensor and analyze its accuracies considering various factors. The experimental results obtained with three databases showed that our system can be operated in real applications with high accuracy; and the dissimilarity of the finger-veins of different people is larger than that of the finger types and hands.

sensors-15-16866-f007: Proposed finger-vein capturing device used to build a good-quality database.

Mentions: Figure 7 depicts our finger-vein capturing device. This device consists of six NIR light-emitting diodes (LEDs) operating at a wavelength of 850 nm and a webcam (Logitech Webcam C600) [26]. Alignment of the input finger-vein image in the capturing process was achieved by attaching two bars to the device to guide the positioning of the fingertip and the side of the finger. This was done to ensure a high similarity between images acquired from the same finger of an individual and thus, increase the matching accuracy. By adding the guiding bars, our device is able to acquire finger-vein images for each person non-intrusively. This enabled us to create a good-quality finger-vein database with enhanced alignment of the finger position, and to use the database for the following experiments.
